We had 3 quotes for attic ins. (blown in) first one was way high and even suggested we do it ourselves, next one was high and wanted to know if there was more, third was Northern Ins. Quoted us in the next few days. Quote was bang on, Rob Adams was very honest helpful and observant to our needs not the company's. It was scheduled a.S.P. After accepting the quote. When the crew came to do the job they were professional, efficient, and clean. To us it seemed like big job or small job they were there to help and do the job. Staff at this company cheerful, helpful and on the ball. Have and will continue to recommend great northern insulation to friends and strangers.
We had our attic insulation increased from an R20 tp R50 by Great Northern Insulation. The process was very easy. First we had an estimate then arranged for the application which took about 2 hours. The men that did the work were pleasant and took precautions to miniseries any mess. There was a ceiling pot light loose after the work and the company came back to fix it! The whole process was quick and painless!
We are still waiting for the pep rework to be completed for the GreenOn program which should be another week or so.
I highly recommend Great Northern Insulation.
The quote went smoothly and all my questions were asked and answered efficiently. You have to give your credit card information over the phone which was a bit concerning and old fashioned.
The work was scheduled efficiently and the team arrived on time and were professional.
Because the work is in the attic we did have a light fixture come loose which they returned to fix quickly.
The rebate process requires "trust" - you pay the full amount with a promise that you'll get 75% or more back in rebates but I'm not sure how long the process takes.
Initial contact - Rob - was sincere, honest and displayed well groomed customer service skills.
Inside contact was courteous.
Installers - where punctual, friendly and cleaned the attic access area when job was complete.
Overall - this was a comfortable contractor / customer transaction.
Sales rep did thorough inspection of crawl space and very tight attic space before giving a very competitive quote.
Very knowledgeable workers who did a great job and discussed before what they were going to do. They were neat and tidy.
The first time they came they sprayed some pipes INTO the insulation.
It cost me $150 just for the plumber to show up, and over $300 total to fix it.
Then they came back again and were supposed to spray my garage ceiling and didn't, and did a half-assed job on the two walls that they did do.
Also, the second visit they were told to come in the afternoon and showed up first thing in the morning.
Arrived on time as scheduled. Plastic drop sheets placed to keep hose clean. Stairs and room with hatch closet covered with plastic. The 3 guys worked great as a team. All debris cleaned up and job finished in a timely manner. Have already recommended them to family members and neighbors.
Service was excellent beginning with sales representative arriving on time and answering my questions. The installers arrived promptly at the pre-arranged time and were courteous and polite. I am very pleased that my attic is now up to code for insulation.
The person that provided the quote was very knowledgeable and provided quick service. The crew that came to do the install was very courteous and efficient. Excellent job all the way around and I would definitely recommend Great Northern Insulation to others.
Great Northern was very quick when it take to setting up the date to come and do the job, their installers were also very friendly and efficient! They brought my attic up to R50. The only thing I had an issue with was communication with the office, something that needs a little improvement.
Thanks for topping me up!
GNI provided a competitive quote. The Ladies in the office had a cancellation and got a quick installation date set up for me. The installers showed up on time and completed the work, cleaned up and were on their way. All in all a very efficient job from quote to installation.
This is a great company to deal with. Upon meeting they provided us with thorough and easy to understand process for insulating our home. They also provided and assisted us with the rebate program available to us. Matt Reesor was very informative and promptly organized the insulation of our home. Office staff was very professional to deal with. Installation crew were prompt, efficient and cleaned up after the work.
All in all very satisfied and have recommended their services to friends and family.
The team at Great Northern Insulation were great. Period. The quote was very competitive and in fact the lowest of the bunch but what sealed the deal for us was they could delivery quickly when we needed them to. In and out - did not rush but finished as planned. Even though we covered everything up front then still went in and did a better job at covering things up than we did. Really impressed with that as they could have left it. No overspray and consistent application. ie. when they said 2 inches it was 2 inches etc. across the board. Best part was it was easy. Simple - done - clean and good price and the guys were nice to deal with and polite. And, that matters to me. They cared.
As far as I know, they did a great job. However, there was no contact from the installer either before he started or after he finished the job. I have no idea what the pictures look like. I have no idea how much insulation they put in and the installer did not knock on my door to tell me he was starting or that he finished. If I hadn't heard the truck I would not even have known he was here.
Overall, I am not happy with the fact that I did not receive any communication on the state of the attic or any details on what was installed. For all I know I have paid for something that may or may not have happened according to the quote.
I just got finished with Great northern insulation and I would highly recommend them. The service was perfect, instal was a breeze and the techs cared enough to make sure we knew to be out of the house since I am pregnant and have little ones, they really do an amazing job and know their stuff. Plus the cost was perfect with the GreenOn rebates offered right now. If your looking for a great reliable company look no further.
The spray foam was done nicely. However the helper had no idea what to do. I had brought my insulation down past floor 4 inches so spray foam could be sprayed to it to form a good seal which I had discussed with the sprayer. I was informed they had to put something between joists to avoid overspray which is understandable. When they were done the insulation had been pushed out of the way and other batts had been shoved into this area. The insulation that was used was a bag of R20 24's. This was my insulation that had a purpose and $60 price on it. I was not asked if this could be used which I was not impressed with!! It was cut into various lengths. All that was needed was something to go up to existing insulation to avoid overspray. Now I have a mess along this area and I do not have a good seal! After all was done I had a garbage bag and a half full of garbage that was left.. helper did not know how to run a broom and did not care about his job or know the proper process.
Great service, very informative sales process. Sales Rep Bill was knowledgeable regarding GreenON rebate program and helpful in determining and recommending the products and services that I required. Service was booked promptly and completed on time and as quoted.
I liked the way Great Northern Insulation handled our initial request. Firstly, the gentleman who came to give us the quotation was very though and very knowledgeable. All questions were answered.He then gave us an estimate for the work and approximate time it would be completed. The insulation itself was done without a hitch, they arrived at the appointed time, completed the work in a timely fashion. They cleaned up after they were done. All in all were were completely satisfied with the work done! We recommended Great Northern Insulation to our neighbours and relatives.
The sales person that came to measure our attic was professional and courteous, and got back to us promptly with a quote.
The installation guys did a great job as well. They were quick and they cleaned up after themselves. I could feel the difference of having the insulation blown in the attic immediately. Our house is so much warmer now.
We had an initial visit from Bill who took the measurements, took pictures of the existing insulation and answered all our questions. Shortly after we received a written quote with the eligibility for government rebate. We shopped around previously, but GNI provided the best quote and given great reviews we decided to move forward. Our appointment was scheduled only 2 weeks after us providing the deposit, everything was done great and professionally, guys even cleaned upon completion. I highly recommend Great Northern Insulation for their exceptional service, professionalism and overall quality of work.
I personally prefer this company over any one because they explained me the problem i was having with my living room getting cold. The service they provided was beyond my expectations. I am person who loves to do a clean job and wish the same from others. It was a very clean job and care was taken not to spread the insulation all over my carpet.
I would recommend my family and friends.
We are very pleased with the work completed by Great Northern Insulation. Both the technicians were friendly and considerate. The work was completed in a timely and professional manner. The work areas were cleaned up after the work had been completed.
Over all Great Northern Insulation did a great job increasing my attic insulation to about R65 from R25. Jake, Alex and Dan showed there passion for doing a good job and did there very best to minimize any dirt and dust in the house. They arrived 5 min early and were kind and informative throughout the entire process. If I would add some feedback for places to improve, it would be to have better communication and quote times up front. I understand it's a busy time right now but lacking in this area could send a bad message to a potential customer and take the focus away from the excellent job done by Great Northern.
It was great to call a company recommended by someone and have a good experience. I was impressed with the courteous and professional interaction I had at all employee touch points from start to finish. I am very happy with the service, price and quality. No fuss, no mess, all in all a great experience.
I had a very positive experience with great northern insulation. We had them in to do our attic with blown in insulation and it was a positive experience from the beginning to end.
The gentleman doing the quote showed up on time, and within a week of calling. The follow up call for organizing the work to be done was handled very well, and the lady on the phone was quite polite, even though we got disconnected half way through. The gentleman who actually did the work were polite and efficient. They built up a wall around the attic access hatch to prevent any insulation from falling out, insulated the hatch itself and put a gasket around it as well. Very happy with the service.
I was impressed that GNI provided a reminder call, they showed up in the early part of the time bracket given and went to the extra care to ensure floors and stairs were appropriately covered so everything was kept clean and damage free. Customer service was also always pleasant whenever I called in.
We were very pleased of the work that was done in our attic the gentleman explained everything and cleaned up after they were done. Very satisfied with the work.
Thank you, I have recommended two other families to get a quote from your company.
The sale quote was done the same day and the bill was the same as the quote even though they had to blown in some extra because they ran out of bags on the last day. I really appreciated the hard / dusty work they had to do install insulation!
The only problem we had is they were booked to far ahead so we had to wait several weeks to get the job done.
3 weeks ago I had Great Northern Insulation spray foam my basement walls and rim joists. Two men arrived on time and did an excellent job! They were courteous, helpful, and respectful of my property. A very clean, professional job was done and the difference in warmth was immediate! Very happy with the product and service, and the price was very competitive.
GNI did a good job as they did what they said they were going to do and the work seems to have filled the goal we wanted (improving upstairs temperature, less heating).
Marks deducted as they were supposed to contact me when they were on their way so I could leave work to meet them and they did not. In addition, not all the materials required were on hand when they arrived but the situation was rectified quickly and apparently some sort of communication error.
The installers were very respectful and courteous.
Foam and spray were scheduled as 2 different visits. The foam insulation went smoothly. The technician was quick, courteous and arrived on time. Unfortunately I do not know his name.
The spray insulation was not quite as smooth. No one told me when I made the appointment that we had to vacate our home for 24 hours after insulation so we had to reschedule. Our next appointment was scheduled for 830-1030 and the techs showed up at 720 which was quite an inconvenience. They removed the old pink insulation and replaced it with spray which looks fantastic. Unfortunately they left quite a bit of pink insulation in the crawl space when they were to remove it all. All in all, the job was done well and I would recommend them.
The team at Great Northern Insulation has been great to deal with from start to finish. The crew that did the work on the house were very clean and professional. Would definitely use this company again for future products.
The quote and the install off the insulation inside the house, was great. Awesome job!! The 2nd phase to blow in the ceilings was changed a few times and they also arrived unannounced, didn't expect that. But over all we thought the job was done well.
The two young man from Great Northern Installation arrived when they were expected, were friendly, professional and extremely courteous.
The premises were left neat and clean and they locked up the house for us.
We have been trying the last few days to get in touch with you to rectify this situation. Please call us at your earliest convenience so we can look into this further. 1.800.265.1914.
We were happy with the job done. A good consistent coverage added to existing insulation. Cleaned up well after and were careful with equipment coming into house. Only complaint was we were scheduled for noon and they arrived 2 hours early. Just good luck my wife was here at the time.
Those two guys that did the job were efficient and knowledgeable. They kept the rooms relatively clean considering how messy it was. Clean up afterward was satisfactory. They worked almost without breaks and finished it the same day. We notice the difference in temperature the first night after the job. It was warmer.
We were advised the Government were giving incentives to upgrade our insulation in our attic. We contacted Matt, a gentleman came out - had a look, advised us what we did have up in the attic and suggested that we get the sprayed in foam to upgrade our insulation to 60. An appointment was scheduled, 2 gentlemen came "early" for the appointment (which was nice), laid plastic from the front door to the attic hatch. After they were finished, they cleaned EVERY little bit of insulation up, and were on their way. A Job Well Done, and we would Recommend this company to our Family and Friends. Looking forward to receiving the cash back from the Government.
Dealing with Great Northern Insulation was a good experience from start to finish. They were prompt at coming out to provide a quote and once quote was accepted they made effort to set an appointment date that was suitable. In advance they also made me aware of any potential rebate programs that I might be able to take advantage of and were willing to assist with that. The workers arrived on time as scheduled and were respectful of the house by laying plastic for them to walk on. They allowed me to view their work prior to leaving and answered any questions/concerns I raised. They also cleaned up after they left. Payment was easy as they accept most any form. I would definitely use this company again in the future and totally recommend Great Northern Insulation to others.
I was so happy with Great Northern Insulation. First off, they made me an appointment for the quote at 7.30 am and he was there at 7.25 am.
When they came to do the work, they came at 8 am and with 2 crews so I only had to take a ½ day off work. They where so clean you can not tell they evan came. And every guy on the crew was very nice and happy.
This was a mixed bag experience. They came out to do the quote very quick and friendly. They were very busy so they didn't actually get to my house for a month where I was informed that the exterior walls couldn't be done with blown insulation due to lack of sheathing. That is fine and I'm glad they didn't do anything that would be bad for me in the future, however, I could have taken down the exterior walls during that month in preparation for insulation instead of finding out (a month later) the work couldn't be done.
The crew were nice but left my toilet seat soiled, garbage on the exterior/interior and broke my stair railing.
Payment has been interesting since they were supposed to take a 20% deposit but didn't. Randy was also very nice about returning my drill that the crew somehow took by mistake.
When the installers came to blow in the insulation they were very professional. They asked before they started the work if we were going through the government grant. As this was a new program I had not looked into the details. They were great in proving that to me. They made sure to take a bunch of pictures before and after installations so they could complete the application for us.
When they completed the job, they cleaned everything up and made sure the furniture was put back in it's original position. I would defiantly recommend GNI to other people.
Attic in the shop and house needed insulation blown in. Called GNI for a quote and they immediately responded by sending out a saleperson. Very nice people. 3 weeks later the insulation was blown in, installation crew was very professional and quick.
I was very impressed with Great Northern Insulation. They got back to me quickly with a quote, and the estimator gave me information on how they could save me money using the new government grants. The scheduling people were very friendly and easy to work with, and called a few days before the installation date to confirm the date and time. There installation crew showed up on time and was very professional. They walked through the job with me and answered all my questions. At the end of the installation the site was clean and they filled out the paperwork for the grant. The only thing that I can find fault with is a couple of the rim joists were overfilled with foam. It will make it hard to put Roxul insulation in them for the fire rating.
We had insulation blown into our attic of our home. We were very satisfied with the service. Workers arrived exactly on time and were very friendly and courteous. They cleaned up everything and there was no mess when they finished. We are very pleased with Great Northern!!! Great service.
A great experience with Great Northern...sales/service and installation people all customer oriented...The appointment was kept, on time and the 3 installers worked effectively together....cleaned up after, and thanked me for the business....I would recommend your organization again...and hopefully your doing my installation of upgrading my home will have others ..who are part of our immediate neighbors will consider doing do the same...They took before and after photos which I was told I could get anytime from the sales contact number.
We have batt insulation installed on our new two storey home, with spray foam in certain areas of the home. The quoting process was easy and came back very affordable. The scheduling was completed easily, and this included some last minute changes within a week before the start date. Once realizing we needed spray foam in some areas behind back framing they showed up the next day, although they did miss a spot that was requested.... the came back the next day again to finish. They did leave a bit of a mess for me to clean up, but it wouldn't stop me from using them or recommending them.
The girls I dealt with in the office for payment are very friendly and easy to deal with over the phone. I wasn't a big fan of leaving a cheque on site in a home under construction as there really isn't a good spot to leave it... I would suggest that after you pay the 20% down ahead of time, they bill you the rest and have an option to mail a cheque.
I was pretty impressed with the service and work that was done.
The guys did a great job and were very professional and cleaned up after them. The only thing was that they didn’t do above the garage and my garage gets very hot in the summer and I was hoping that this top up would help it cool down, I called and they explained that they don’t do it unless you have a heated garage. But if I was to put heat in my garage they would have to come back, set up and do that small space. Thats like a double job. I thought a supervisor would have come after the job and inspect the job to sign it complete.
Your people arrived on the scheduled date. They were very polite and took care of my belongs. Put down plastic over the rugs on stairs and removed shoes when necessary. They were able to put hose through upstairs window and started to work. When finished they cleaned up and left everything as it was. They asked if I had any questions and answered what I had and what to expect. Very pleased with job and the workmen that did the job. Very satisfied.
The installers, Dan and Henry, were top notch. Dan noticed an issue in my attic on the day of my installation and rather than just going ahead and finishing the job he actually pointed out the problem to me and recommended that I fix it before the insulation was installed. This was done and they came back a few weeks later to complete the job. I appreciated his genuine concern for making sure that the work was done right.
The guys were great. Showed up during a snowstorm and did a awesome job. Covered all my stuff in the garage and vacuumed up everything when they were done. Great job and I highly recommend them!
I was very happy with the service provided by Great Northern Insulation. They came when expected, took the time to keep things clean and tidy and made sure I was satisfied before they left. Reasonably priced, and efficient.
At first I was very happy with the job but then it kinda went down hill. The workers were very friendly but after they left I found a few minor details that were missed such as leaving plastic over the lightbulbs.. tape over the outlet covers and some overspray on our brand new washer and dryer. Now the overspray came through a area at the top of a wall that was being coated and went into the next room landing on the machines. I have since contacted Northern Insulation 6 times just to find out what to use to remove this stuff with out damaging the machines. I was told the service department would get back to me and still I have heard nothing. I was told its a special removal product that cant be bought in stores. Fine. So here I sit still waiting one month later and still nothing. Very disappointed.
The sales person was up front about the timing of the job completion and scheduling and work was all completed as per telephone discussion. Everyone we dealt with was very professional and friendly. Although an estimate was only given ahead we thought the final price was fair.
Thank you for your service.
Professional, quick and efficient. Quote was dead on with no hidden fees. Guys came in and completed the job leaving no trace of them having been there except for a warm house. Would highly recommend.
I am happy from start to finish with Great Northern Insulation. From receiving the initial estimate to completion of work, everything was professional and completed in a timely manner. The foam insulation to our unfinished basement has already made a difference to the feel of our home in this cold winter. I would not hesitate to recommend Great Northern Insulation.
The two workers that came were very polite and concerned to minimize any mess. They communicated what they were planning to do and gave a rough estimate of how long it would take them barring any unforeseen challenges.
Had no issues with the workers and how they conducted themselves.
As for how to tell if they did a good job in the attic, I guess I will now know until we have the energy audit completed in a couple weeks.
My only suggestion is maybe provide the workers with a camera so they could take a picture to show the customer, if the customer is unable to go up into in my case the attic.
Overall a pleased customer and would recommend!
The crew from Northern Insulation were wonderful from the beginning of our job right until the very end.
Courteous, professional, competent and efficient.
We would highly recommend them to others.
Thank you, Northern Insulation.
Service was great. The workers showed up when they said they would, and did exactly what they said they would. They communicated all the steps, and showed me the result when they were done. Very meticulous when they cleaned up afterwards and apologetic when the hose put a mark on the wall. There was not a lot they could have done to prevent it. Overall, I thought the service on all ends was great and I would recommend them to others.
Unprofessional. No paperwork reviewed. Just left without a discussion with customer. Seemed like 2 kids out of school with no customer service training. Insulation left all over our bedroom.
We are very sorry to hear that your experience was less than satisfying. We pride ourselves in customer service excellence and it is very clear that on this occasion our service was below our customer standards.
We would like the opportunity to discuss this matter with you further if you can please contact us at 1.800.265.1914.
Thank you for your feedback.
I contracted GNI to spray foam the basement walls in our century home. The whole process from start to finish was very professional, from the initial consultation, to follow up for appointments and guidance for the provincial rebates. They came on time on the original appointment date. The guys were very professional and courteous. The application was consistent and the clean up was thorough. Overall the experience was very good and I would recommend them to family and friends.
I have gone back to Great Northern Insulation yet again for their services, and was not disappointed.
Their quote guy Matt is friendly, professional and provides top notch customer service.
A small area that was supposed to be insulated was missed the last time I used their services. I called Matt right away to inform him of the honest mistake, and he had the crew back to my house that same day to finished the job, so I could move forward with my work. You don't come by that too often anymore.
The work was done properly with very reliable crews who clean up when they are done. What more do you want?
The first pair of installers arrived on time, and were great to deal with. The first guy hopped out of the truck(sorry I can't remember names), and I said you're not fitting in there(it was a pretty tight crawl space). The second installer was smaller, so he was elected. Once they warmed up the truck the actual spraying didn't take very long. I went down in the basement, and headed into the crawl space later in the day, to hook some duct work back up. Unfortunately I noticed some cold draughts because in some hard to reach spots there were holes in the foam. After a few phone calls they set up an appointment for a truck to come back and do some touch ups. The second pair of guys were super polite and easy going. The guy working the truck said it was his first day on the job. They spent more time touching up than the original spray job took. They fixed everything that I had marked and mentioned concern for one area that was nearly impossible to get at. Overall a good experience, and I have recommended them to other people.
I liked the work performed. The crew showed up on time as scheduled and completed the expected work without incident. Also provided some tips at each step to better prepare for the next step. I would use Great Northern Insulation again for my next project.
Friendly service, showed up on time and the guys were great! However they didn't bring enough bales (short 3) of insulation to complete the job (because the new shipment didn't arrive on time in that morning), so I drove back to Woodstock from Ingersoll with one of the guys in my pickup truck to get more bales so we could continue with the job. That was totally my offering to do so, the installers didn't ask me to do that. They first called in to try and arrange someone to deliver but no one was available. It was easier and quicker for me to go than them in the big truck. My communication review is poor because of one step in the process. The scheduling process. After i accepted the quote, I was supposed to receive a call within a few days to setup the install and i didn't. I had to call a couple times to get that setup, (phone tag) I think that can be improved on (at least in my case it could of been).
The young crew who applied the spray foam insulation worked quite quickly and efficiently ensuring that there would be minimum overspray. They answered all questions that were asked. They cleaned up thoroughly when finished. My only concern was that, when spraying in the space behind where two drawers are housed, either too much insulation was sprayed or it expanded too much. The result was that several inches of the side runners for each drawer and the back support for one of the drawers were completely covered and the drawers could not close. It took a total of about 5 hours to scrape off sufficient insulation to permit the drawers to close.
The 2 men who came to do the batts install were rude and worked very slowly, arrived late and left early.
The fellows that did the blow in were great They arrived did their job in a timely manner and did not leave till they were finished. any negative rating is for the first 2.
GNI was contracted to to spray foam our basement headers and overhang. The whole process went smoothly from the quote to the install. Communication along the way from GNI was really good. Install went well with no mess afterwards.
Would highly recommend their team for your insulation needs.
Two young guys came, one was new and learning. They were very fast to set up and kept everything clean and tidy in the home. They were friendly and professional. The only problem I had was when I paid by phone with my credit card I wanted to receive a paper copy of my receipt but I never received one and had to call back and get an email copy sent to me.
This company, from the sales team, office ladies to the installers were fantastic! They provided us with a detailed quote, scheduled the time for installation and were prompt, clean, professional and friendly.
Everything was done beautifully and they left the area spic and span. We are completing our main floor renovation as well as our basement and I wouldn’t go anywhere else for our insulation needs.
Fantastic company and team!! Thank you for a PERFECT job!
We demolished an existing home and rebuilt custom. GNI was easy to get a hold of and provide an accurate estimate for services required based upon architectural drawings. This abiltiy seemed challenging for a number of other companies contacted for the same services during the budgeting phase. Once framing was completed, I had a GNI representative visit the site to visualize any challenging aspects and verify the original estimate was accurate. The revised quote was marginally LESS than the original estimate, despite some challenging aspects and my requirement for various phases of work to be completed at particular times during construction. I had others quote on the work at this time as well and GNI was both the most professional (in most cases by a very wide margin) and the least expensive. Not often a common combination of attributes.
GNI was always accommodating of my requirements and specifically trained (and certified where required) crews for the work required were sent in a timely manner each time. 1. Spray foam rim joist cavity only prior to basement framing 2. Spray foam entire exterior perimeter from footings to attic 3. Attic and soffit prep Moore vents, batts in tight attic corners at perimeter above coffered ceiling sections and vapour barrier 4. R60 attic blow-in fiberglass.
I will note, some minor damage to a bathtub and front door system was caused and GNI was again easy to deal with and reconcile the situation in a mutually agreed upon manner.
I am EXCEPTIONALLY particular on how everything is completed and I would certainly use GNI again. I would merely ask that further care be exercised when applying accustical sealant to vapour barrier/top plate and when working around brand new fixtures.
We're so please Christian, that we were able to work with your schedule and any hiccups that may have arose we were able to accommodate to your needs! Thank you for the recommendation and we hope we can work with you again for all your future insulation needs.
Thank you for choosing Great Northern Insulation!
Great norther insulation: Had my mobile home floor spray foamed. Staff was on time polite and professional. Did a great job. I Would Highly recommend.
Thanks Dave for the recommendation and for the great review! It was our pleasure to help with your insulation needs and we hope you consider GNI for all your future insulation projects!
Thanks again Dave for choosing Great Northern Insulation.
They did a good job of the work they were hired for. They showed up on time and were efficient. The price was what they quoted.
Thank you Dale for taking the time to review us! We're overjoyed that you were so satisfied with the work we did, thank you for choosing Great Northern Insulation!
Both of the technicians were very professional. They added the extra insulation through the trap door in the garage very efficiently. The best part was that they swept up all of the little particles of insulation that were left in the garage. They were very efficient and polite.
That's so great Lizzy, Thank you for taking the time to review us! We're so happy that you were so impressed with our services from start to finish as we pride ourselves on being the best! We hope you've already started noticing a difference in the temp of your home and please think of us again for all your insulation needs!
Excellent service, the gentlemen on the spray truck were knowledgeable, professional. When job was complete, cleaned up job site.
Thanks Eric for the great review! We're so happy you were thrilled with our service from start to finish. Thank you for choosing Great Northern Insulation!
Very happy with our dealings with Great Northern Insulation. Great product, employees, & price.
Our pleasure Jonathan, Thank you for taking the time to review us as well as the 5 star rating! Much appreciated. Thank you for choosing Great Northern Insulation for your project's needs.
We had GNI insulate out attic a few years ago when the 2 levels of governments were offering grants on energy upgrades. Great experience.
So when we recently replaced our 3 season sunroom with a 4 season one, and when it came to insulating the deck on which it sits, we decided to try GNI again. We weren’t disappointed.
The technicians got there ahead of schedule and finished up ahead of schedule. The job itself was done quickly and efficiently, and there was no mess left under the deck. I had asked for an un-used window to be sealed up as well, and it was. The technicians were polite, professional and answered our questions.
I have no reservation what so ever about recommending GNI.
Thank you so much for recommending us Jamie. We're thrilled that you've been so happy with our services and we hope that you've already started noticing a difference in the temperature of your home!
Everyone from the salesman the girls in the office to the two guys that did the job henry an other man. Sorry can't remember name were excellent. They explained what they were going to do 'did it' did an excellent job of cleaning up thanked us and left. Hopefully 2 very valued employees.
Thank you Bob for the wonderful review! We're so pleased that you were happy with our service from start to finish!
Thanks again for choosing Great Northern Insulation.
The two Great Northern Technicians were courteous and extremely careful to cover our white carpet when entering our 2 story home. They completely covered the entire walkway through our home with plastic to ensure that they did not soil our carpet. That sooo impressed my wife and I as we NEVER walk barefoot on our carpet. We ALWAYS wear slippers.
These guys were courteous and very professional -- ensuring that they cleaned up everything before leaving our home.
We'd recommend them to our friends in a "heart beat"!

It was great working with Great Northern for our spray foam insulation needs. Bill who provided the quote was helpful and took time to answer our questions, and provided helpful advice in a follow-up call several weeks later. Due to some renovation scheduling issues, we had to rebook the insulation a couple times, and the staff were always friendly and accommodating over the phone and via email.
It was our pleasure working with you Sarah, We hope that you've already started noticing a difference in your home. We're also thrilled that we were so accommodating to your schedule and needs as we pride ourselves on that! Thank you for choosing Great Northern Insulation.
Guys were on time and organized. There was little to no over spray due to the ploy they put up. All in all very pleased with everything. Would recommend them to anyone.
Thank you Brad for taking the time to review us and for the 5 stars! We're so pleased that you were happy with the work we did!

We're so happy that you were impressed with our services from start to finish Ken! Thank you for choosing Great Northern Insulation and we hope to work with you again!
This is a very easy company to do business with. The initial quoting process took only 10 minutes and the actual job was finished in a half hour with no mess. I had in error booked the job in my calendar for the wrong day and was not home when they arrived. After they found me by phone they offered to come back that afternoon to do the job. I really appreciated that.
No complaints here. I would use them again.
That's so great to hear Bryan! We're thrilled that we made the whole process super easy and were able to accommodate to your needs! Thank you for choosing Great Northern Insulation and we hope to do business with you again!

On Oct.13, 2017 I had insulation blown into my roof area by Great Northern.
The 2 installers Ross & Justin arrived on time and introduced themselves They were very pleasant and explained how the insulation was going to be blown in. They took off their boots and checked my closet upstairs where the attic door was into the roof. They then laid floor covering on my entrance way and up the stairs and reminded me to be careful if I had to use the stairs. They quietly went about doing the job and Justin explained that my bathroom vent had fallen off inside the attic and that he had fixed it.
The job was done quickly and efficiently and before they left they lifted all the floor coverings and checked that the floors were left clean. On leaving they shook hands with my husband & I and thanked us for choosing Great Northern.
This is our 2nd home where we have used Great Northern for our home insulation needs and would not have a problem recommending them to anyone.

Great Northern Insulation did a great job on insulating my attic. They arrived on time, were very professional and informative about what they were doing. Honoured their quote although is was a more costly job than originally priced. Very pleased with their work.
Wow Tish! thank you for the awesome review, it's feed back like yours that keep us going and obviously let us know we're doing a great job too!
Thank you for choosing great Northern Insulation!
Great Northern Insulation was amazing to deal with. I got a quote from them and the guy was so helpful and explained everything and what would be my best options. Then after I made my decision, booking, paying and having the work done was so easy! They were right on time, estimated it would take a few hours but took no time at all, were clean, polite, and didnt even make much noise. It was a rainy day so they put plastic down all the way from the door to where they were working so clean up was a breeze, and then once they were done they explained what they did and asked if I had any questions. Would Highly Recommend them to friends and family.
Thank you Heather for the 5 star rating. We're all so thrilled that you were impressed with our services. We pride ourselves on being the best and we're so happy you saw and experienced this at all stages of your insulation project!
Thank you again for choosing Great Northern Insulation and we hope you use us again for all your future needs.
Dan and Henry were the gentlemen who attended to our condo unit to upgrade the insulation. What a credit they are to your company! They were on time, answered my questions, let me view the work done and cleaned up after themselves. A portion of our skylight insulation had fallen off at one end - they taped the piece back up and secured the rest. Polite, friendly and helpful. My husband arrived as they were about to leave, they answered his questions, spending quality time with the customer. We are extremely happy with the service and would definitely recommend your services.
Thank you Wakt and Kathy for taking the time to review us! We'll make sure to tell the crew on how impressed you were with the service! It's employees like Dan and Henry that make GNI so great! Thank you for recommending us and we hope you've already started noticing a difference in your home!
The 2 man crew that came out to top up my attic were very professional curious and humorous.
I could tell they enjoyed their job and worked well together. They did the job right and I am very happy with their work.
The only thing I would like to see improvement on was the service from the office.
The sales rep didn’t bother to contact me regarding confirmation on installation times and dates. I had to make several calls and multiple emails to ensure they were coming.
Thank you Stuart for taking the time to review and for giving us 4.5 stars! We're thrilled that you were so impressed with our services, We'll make sure to tell the crew! As far as the office, we apologies that we missed the mark on this one but thank you for the feed back as it allows us to become better!
Thank you for choosing Great Northern Insulation.
We have a home built in 1846. We had Great Northern in to quote on adding insulation to our attic. Up until that point, running the A/C had no effect on the temperature inside our home. Great Northern brought in a fantastic team. They showed us how we could receive energy audit rebates and did a whole home evaluation. It turned out that our basement was as big a problem as the attic. They suggested we have our old stone foundation spray foamed. We also have a crawl space with a dirt floor that they suggested vapour barriering. We also had channels running from our attic to our basement. Terrible for temperature control. They removed all of the old insulation from our attic, air sealed all leak points in the attic with spray foam, and then blew in new insulation to to an R60.After learning about the importance of air sealing, I am so glad we didn't go with a company that would have just blown in a bunch of insulation and left us with a leaky house. The Great Northern Team did an outstanding job. We had been told by two HVAC companies that to properly control the temperature in our home, we needed to completely remove the existing ductwork and have it rerun. The cost would be $8,000-$12,000. We decided to let Great Northern do their thing first. I am so glad we did! Our home now heats and could great, without the costly ductwork change. You are making a great decision if you choose Great Northern to help you in this area. Great Company with even greater employees!
Wow Marshall, Thank you so much for the great review! It's feed back like yours that makes us feel so proud of what we do!

Insulation was added to attic on the first visit to my home. On the second visit, they applied poly and insulation to the crawlspace. Work was done professionally and complete.
Thank you John for taking the time to review us! We're so happy we excited your expectations! Thank you again for choosing Great Northern Insulation!
I received a referral for Great Northern Insulation from a relative who was very pleased with their work at his place. Going with GNI was an excellent experience. Bill came by very quickly to perform the quote. He was extremely professional and took the time to answer all questions which we had. Booking the job was easy and they were able to accommodate me for the date which I was hoping for. The crew that showed up were very courteous. They were very careful with the spraying and there was no mess was left behind for the homeowner to deal with. Overall great experience and I would recommend this company.
