The Pros who did the work on our house were very friendly and responded to any questions and concerns I had.
The team who did the attic took the time to explain the finished results before they left. They did a great job, and took care to lay down drop sheets everywhere they needed to.
The team that did the drill and fill also did a good job, and were sure to put down drop sheets in areas we couldn't cover ourselves. The only things I was a little unhappy about was that some substance was dripped on our floors and carpeted stairs which is sticky and I'll have to try to clean it. I was surprised that the holes were not paint-ready, as the information packet said they would be. I will have to do some filling and sanding myself before re-painting. They were a little rough with some of our belongings that we couldn't move, but were very apologetic about it.
The team who did the basement missed a whole outside wall, and did not come to us with any issues they might have had. So there was some confusion or lack of communication there. But the work they did do, was good.
Overall, the experience was good. They did the work fairly quickly and were able to schedule me in sooner than I expected.
First, Great Northern Insulation was a late for appointment, just over 20 minutes But thankfully they were professional and respectful. Went over work to be done and and then got right to work. Would recommend this company.
Jeff and Tyler did a very professional job. They came early and stayed late. We were very pleased with their thoroughness,and attention to detail. They explained what they were doing,and gave opportunity for feedback and to ask questions. We appreciate their hard work on our behalf. It was a job well done.
The workers were wonderful, Jeff and Tyler, however, they were misinformed about the jobs details and did not come prepared, not for the weather and did not have all the necessary materials, through no fault of their own. They were not given the correct information from the office.
I would highly recommend Great northern insulation. They showed up on time were very efficient and explained their job well. Tim Jake and Hunter were very friendly courteous and did a great job cleaning up. Job well done.
Henry and Devon were courteous and professional. They smiled a lot!!!! They asked questions and listened to our answers. When we asked questions they listened and answered directly. They explained everything that was done and gave us assurances which were very much like those given during the estimate. I felt very comfortable having them in my house.
What I liked about my experience with Great Northern Insulation company, they arrived on time, were very courteous, and explained the process to me. What I didn't like was they did not have all the material with them and will have to come back another day to finish the job.
Workers arrived on time, put down floor coverings for cleanliness, explained what they would be doing and how. Worked efficiently I believe. Were done fairly quickly, cleaned up after themselves and both guys were very pleasant. Workmen were Sean McLaughlin and Chris L. ( don't know Chris's entire name-sorry )
Toasty warm in my garage
Your employee's worked diligently and completed the job in an orderly fashion. They were very friendly, informative and very neat on the job.
Will definitely recommend your company to friends, family and acquaintances.
Thanks for a great job
Both services were provided in the same day which was great. Both teams arrived on time and were professional. I felt comfortable leaving the house to let the teams complete their work.
The experience with GNI was excellent right from the initial contact via email, the follow-up email and phone call, the timely home visit to assess our needs, the quote provided by Bill Barlow, the follow up scheduling and payment emails and phone calls. The installation crew (Tim and Sean) were very professional, polite, explained what was happening and completed the work to our complete satisfaction. They did an excellent job cleaning and vacuuming and left our home the way it was before they arrived.
this was the third time we have used Great Northern to upgrade insulation.
The crew is always courteous and pay great attention using floor mats to protect the floors and then make sure no debris is left on the floors.
When complete the leader asks if there are any questions and generally leaves a positive impression of the service.
Jake and Aaron came in and did a great job. They were nice, knowledgeable and respectful to me and my home. If I ever need an insulation job done again, I will certainly use GNI again as well as refer them to anyone I hear who needs a job done.
I was impressed by the detail in the estimate. The estimate outlined every aspect of the job being quoted and the price was fair. I didn’t find this to be the case with other estimates I received. The knowledgeable and friendly installers showed up on time, placed protective plastic on all floors they walked on and generally kept the mess to a minimum. I was impressed that no time was wasted with personal conversations between employees or cell phone use. The workers were very professional. The job was completed exactly as quoted. I’m very happy that I chose Great Northern Insulation for my attic insulation home improvement job.
Great Crew! From the start great company to deal with. The gentleman who came to quote the job was quick, professional and knew his stuff. The install crew ( Henry, Devon and Mike) were extremely efficient and clean. In and out in just under 3 hours. Definitely recommend them.
Two young guys cameo insulate the attic. Informed me of what they were going to do and what they planned on doing. They informed me of a couple of issues and they took pictures
they left after cleaning up and left the area clean and neat. I was very impressed with the workmanship and the quality of the people and there work.
Work was performed without incident and in a reasonable timeframe. Both Henry and Devon were very pleasant and answered questions when required about the work that was being done.It was a nice experience to have this job completed properly and at a reasonable price.
3 gentlemen came to do the insulation work. They showed up on time abd where polite and professional. Plastic was laid down they got the equipment to spray the attic. I requested additional attention in one area which was promptly addressed. They cleaned up after themselves.
I was very satisfied but would have had liked the opportunity to have been able to inspect the completed job but everything had been cleaned and sealed. We are noticing that the house is warmer.
The crew (Chris L. and Sean M.) was supposed to start a 8:00 am, but through some scheduling misunderstanding they arrived at 1:00 pm. Not a big problem as I took the day off. As they were about to get started they saw that there was not enough attic space to install styro-vents over the garage. (Unfortunately this was not brought to my attention at he proposal visit.) Instead of abandoning that part of the job (one possible option presented, though nor acceptable for me as I needed the garage ceiling insulated), we came up with an alternate solution that involved me bringing in a siding contractor on an emergency basis to provide access from the soffits in order for the insulation crew to install the vents from the outside. Once the access was made, the crew was able to complete the rest of their work. Throughout the process they were very courteous, explained the difficulty clearly, showed that they understood my concerns, and worked collaboratively to find a solution that worked. They worked efficiently, were very friendly, and cleaned up after they finished. They turned a potential problem into a successful job. My thanks to both Chris L. and Sean M.
From start to finish the service from Great Northern has been top notch. The salesman was honest, upfront and provided a quote in timely fashion not to mention at least 30% cheaper than the other large company in the area. Kim was able to book a time that accommodated my families busy schedule and kept me up speed to any schedule changes.
The installers arrived on time and were careful to cover any areas that could get some some over spray on. Colin and Jon were great at explaining the process and asked me if I had any questions or concerns. A Great Northern experience. Thank for the warm basement,
I liked the quotation guy, very thorough, clearly explained options and his recommendation.
I liked the two installers, they pointed out a couple of minor leaks in the roof, which was not good news but I'm glad they told me. They were done in about 3 hours, left a bit of loose insulation material in the driveway.
Time will tell if the heating/cooling improves.
I am very pleased with the work completed. Henry and Devon were very courteous and diligent in maintaining cleanliness in our home. There was one potential issue identified which they brought to my attention right away. They were very considerate in allowing me a reasonable amount of time to investigate and fix the concern so the process could continue without having to reschedule.
I was pleased with the work done by GNI. The crew arrived within the time designated for their arrival. They covered the cold room floor to prevent a mess due to the spray foam. It took a little over an hour for them to complete the application. I was hoping for a more even coat of insulation but I am not familiar with this type of insulation because it was the first time that I have used it so maybe it was done to the best of their ability. They brought their hose in a basement window and while doing this rubbed some paint off the window sill.
All in all I was happy with the work done but I will have to wait for some cold weather to see if this process actually prevents dampness from condensation in our cold room.
Both Great Northern professionals were courteous and hard-working. They explained what they were doing and approximately how long it would take. Both Devin and Henry arrived on time and completed the job in the time they indicated.
I really enjoyed dealing with Great Northern Insulation because of their prompt, professional and comprehensive service. The install crew was punctual. They thoroughly prepared before and cleaned up after both jobs. In the attic, they ensured proper ventilation by clearing the soffit vents and installing baffles. They also insulated and air-sealed the attic hatch. The even blanket of blown-in insulation will keep us cozy this winter!
Due to a scheduling error, the crew did not bring the spray foam tanks necessary to complete the basement job. The GNI office remedied the situation by immediately shipping the materials in a separate truck. All the work was completed within the visit. Very happy every facet of this service.
The workers were very professional and courteous, took care to lay plastic down on the floor so my floors would stay mostly clean. They cleaned everything up after themselves and even vacuumed for me. I would definitely recommend them to anyone!
Excellent service, very happy with the employees and all dealings with great northern insulation. They showed up on time, explained what they were going to do, why there doing it and things I could do in future. Cleaned up after they were done and took the time to show what they had done and made sure I was satisfied before leaving.
The work crew showed up exactly when we were told they would and we're completely prepared for the task. The workers were very courteous and knowledgeable and we're speedy and clean. It was a pleasure using GNI and we will be using them for all future insulation needs.
Great Northern Insulation provided us with a reasonable quote, arrived when they said and got the job done in even less time than anticipated. We can already feel a difference in the warmth of the house, and it's only October. They left the area clean and were prompt with any communication. Everyone we dealt with was courteous and approachable. We would recommend.
The crew from Northern Insulation were on time ,friendly and very professional.
They used plastic around the attic openings to keep the dust to a minimum and when completed they vacuumed up anything on the floors. Great job.
The installers arrived on time and went straight to work. The job was completed quickly and they did a terrific job cleaning up the garage floor after they were finished. We were amazed that they could physically squeeze into the loft opening to blow the material into the empty spaces.
The guys showed up on time, were friendly, completed the job quickly and cleaned up thoroughly. Exactly the type of service that I hope to receive when hiring contractors. Well done Great Northern.
I did not get the names of 2 men or don,t remember that came the morning of insulation but they were real professionals. We left the house with our pet to a motel when time was ready for them to get the job done. I couldn,t be more pleased with the job they did. Yes, it was expensive but it sealed out the dampness & now do not need our dehumidifier running. Thank you so much for wonderful job.
I bought a house from the 50's that happened to had not insulation at all, so I decided to give this job to Great Northern Insulation. I have to say that they did such a great job!
The crew that went to my house was really knowledgeable and courteous. They got to my house on time and did the work as expected. They always advised me about their findings while working.
Now, the house is completely insulated: Attic and all exterior walls.
I am very happy with the work they did in my house and I would not hesitate to hire them again and recommend them to family and friends.
The entire process from first contact to completion of the installation was very smooth and effecient. Rob Adams was very helpful and knowledgeable when he attended for the quote. The two young men that did the installation were very friendly and worked quickly to complete the job and did a great job cleaning up after themselves.
I would not hesitate to recommend GNI to my friends.
the guys showed up on time and did the job with no fuss or mess. Only down side was the area over the front door couldn't be insulated because of access issues. We should have identified that before they started so we could have had it openned up for them. good job
I had Great Northern Insulation out to Improve the insulation in my attic.
Devon, Henry, and Hunter were the crew that arrived at my house on the 27th
They were here for about 3.5 hours and did a totally awesome job .
Plastic was rolled out to cover the floors and a very through vacuum job was the
I would highly recommend them to anyone in need of an insulation install.
My house didn't top up the insulation in the past 30 years. It is still the R10 bat. I hired Great North Insulation to top up the insulation to R50.
The guys did a great job. They sealed the kitchen and bathroom vent to the roof for me and spray 16 inches cellulose on top of the bat.
They did vacuum after the work to remove any possible insulation pieces
Good company, great work!
Great Northern, were great to deal with. They were on time and very professional. The crew even took picture of my attic after they were done to show what they did. The whole process was seamless from estimate, to booking, to the actual install from crew. Would recommend them to friends.
Special thanks to Henry and Devon for their work in my very hot attic .On a very hot day.
Hunter and Dave were friendly and accommodating.
Great Northern Insulation was an easy company to deal with.
Only small issue is that there were a few cigarette butts littered on the sidewalk outside my house after they were done. Perhaps they could take them with them on future jobs.
We have used Great Northern services numerous times in all of our homes. As always, your personnel were on time, pleasant and did a great job. Walltite Eco. is not cheap but it is well worth the added expense. We've always been happy with your services and will continue to use you for future projects as well as recommend your company to others.
My garage roof was insulated this afternoon. Henry and Devon did the job. They were friendly and polite. Looks like a good job was done and they cleaned up after themselves. They were very knowledgeable and professional. If I was getting more insulation i'd definitely call Great Northern. I would also recommend Great Northern to friends looking to get insulation done.
We learned of Great Northern Insulation from Lowes in London. Everyone throughout the insulating process from estimate to install was very nice, and very helpful. Kim, our contact at Great Northern was particularly helpful and pleasant to work with. Colin and his assistant came to spray foam the walls, crawl space and vapour barrier and did a really nice job. We're very pleased.
I recently hired Great Northern Insulation to install some spray foam in my basement. The installation was done exactly the way I wanted it to be done and I am very happy the finished work. The crew (Colin and Max) were very professional and I wouldn't hesitate to hire GNI again.
They did a A+ Job. Very professional
I liked how in-depth and knowledgeable Devon, Henry and Hunter were. They were straight forwarded, pulled no punches and got right to the point. I would recommend Great Northern Insulation to anyone.
After looking at the insulation that was sprain in my basement..I was really impressed at the neatness and coverage all on our wall. Peter D and Jake W did a great job. And so polite and efficient. Even thou I know it was a small job...I was never made to feel it wasn't important.
Steve and Cindy Felker
Very polite and diligent. They came on time, but did have a problem finding the entry point to a certain area. They explained when they were done why they had taken a 45 minute break. (one of the guys was new and they had to go over direction).
Great Northern gave us a time line of four to six weeks and stayed within that timeline. When a date was set the installers Henry and Devon showed up on time, were very courteous and performed the task in a very efficient and timely manner. No problems arose and project stayed within the proposed quote. What more could be asked!
Everything went as planned. Henry and Devon showed professionalism and great care to our home during application and cleanup.
The technicians did a great job and went under the crawlspace, even though it was a very difficult space to fit under... Both of them were very personable.
I found it very difficult to get a hold of the salesman on several occasions. This was very frustrating as I had questions that I needed answering in order to move ahead with some of the work.
We just purchased a home that needed a lot of work and we couldn't have done it without Great Northern Insulation! They offered friendly, fast and affordable services. All of the staff were a pleasure to deal with and worked around our schedule to make our plans all come together. The spray foam was beyond our expectations -- super thick and evenly covered. Henry, Devon and Hunter were amazing workers and the front office staff was the best!
This company was great from beginning to end. When our neighbour had Bill over at his place for a quote, we asked if he would mind coming to our place and giving us a quote. We did not have a appointment. Within a day or two, we had a quote and were also told how much our rebate would be. An appointment was set up to suit our schedule to have the install done. The guys came within the time frame that we were given and they did an awesome job. When my husband first saw the guys that were in the truck, he thought they looked pretty young and was a bit worried.....no need, they were very professional. Everything was cleaned up before they left. Very nice guys :) The girls behind the scenes that set up appointments and look after all of the paperwork were also great to deal with. An overall excellent experience!
Process was smooth from beginning to end. Henry and Devon arrived on time (actually they were early). They were very professional and took care in protecting all carpeting, as well as the window opening. The whole process took only around 2.5 hrs, and they cleaned up everything before they left. Would definitely recommend.
Henry and Devon did Excellent work, there on time, no fuss, no muss, cleaned up after selves took no time at all and It was way quieter than I expected it to be...thanks my dog settled right down!
Arrived on time if not before the scheduled time.
Both guys started work right away and worked hard to complete it in a timely manor.
The addressed any questions or concerns that I had.
Cleaned up the area before they left.
Great northern did a wonderful job installing blown insulation in our white oaks home.
On time, polite and courteous the boys installed everything as promised. It's made a significant difference in how the house feels. Humidity is no longer a problem and the air conditioning now cycles on and off.
I live in a condominium complex and recently had additional insulation installed by Great Northern Insulation.
I thought the staff were very polite, considerate (put down plastic prior to protect carpet and cleaned up before they left).
Henry and Devon are friendly knowledgeable we are able to complete the project in a timely manner and cleaned up after themselves. In all great experience with Great Northern insulation and would recommend.
I had Great Northern Insulation spray foam the walls in my house, as well as doing blown-in insulation in the attic.
Overall they did a good job, but I had to have them come back for both operations to re-do parts that were missing or not done up to standard. In the end, the work done was very satisfactory, even though part of it had to be redone.
Bryan and Brendan did a fantastic job of topping up our attic insulation to code. They were very professional, explaining what they were doing.
They even did a great job cleaning up when they were finished! You would not believe how many contractors don't! Nice finishing touch!
I would definitely recommend "Great Northern Insulation", especially Bryan and Brendan to every one I know.
Great job! Thank you for a great experience! We both have noticed a huge difference in temperature on our 2nd floor.
Also noticed that our air conditioner was not cycling on and off as often and our upstairs is now very comfortable for sleeping. I am sure we will notice a big difference in our heating and cooling expenditures as well. Thanks for the savings!
We turned to Great Northern after another company failed to show up for an appointment and never called to reschedule. In contrast to the other company, GNI was professional in all respects and went out of their way to accommodate our tight schedule.
The crew were punctual with their arrival. They were informative letting us know what was going to happen and went about the job efficiently, and professionally. The cleanup was well done and we are very satisfied with the job and the staff.
We were happy with the job done by Great Northern Insulation. We did have some timing constraints with when the insulation could go in (roof being done at the same time) and there were a few hiccups with getting the timing right, but overall the job was done in a timely manner and the crew were polite and efficient.
Very polite workers, took pictures off the wall and rehung them, I was surprised they knew which one went where. They had problems with the equipment (only two units experienced the dust problem) hence dust all over the place, they dusted and even tried to wash the floor. However guys will be guys and do not clean as well as myself, you need to remove the dust before you put any water to it. All in all your company and employees were great. Thank you for a job well done.
My condo hired great northern insulation to upgrade our insulation. I was afraid the appointment time I had been given would interfere with my son's nap time but was able to call and arrange to have the appointment a little later in the day. My son was still sleeping when it was time for my unit to be completed and the guys working were pretty good about keeping their voices down while in the house. My son managed to sleep through the process. The workers used a shop vac to clean up after but I still found that my upstairs was extremely dusty and there was dirty hand prints all over the attic access door. I also noticed some insulation and debris left in various parts of the complex where the truck would be parked each day.
This was one of the best renovations that I have ever experienced. The team was thorough and efficient and walked me through the process every step of the way. They were friendly and accommodating, answered all of my questions with patience and got the job done on schedule with no complications whatsoever. They left my home as they found it, protecting my valued property and cleaning up following the installation. I would recommend Great Northern Insulation for the best quality product and service anywhere! I have already noticed the difference the new insulation is making during this extreme heat wave! Five Stars *****
Unfortunately we are not happy with the work that was done at our property because they caused damage to the ceiling in one of the bedrooms. After the insulation work was done the ceiling drywall pushed down causing a screw hole to form and cracks along the drywall seams.
The actual work they did seems to be fine, but we are upset about the damage to the ceiling. We just had it painted when we moved in two years ago. And we are not sure what the outcome of these cracks are going to be.
I was very impressed as to how polite, professional and on time the Team was. Colin B. and Max J. explained what they were going to do and the benefits to my home and family. They did an excellent job protecting the areas they were entering/exiting, and cleaned up after the job was complete.
Great Norther Insulation came to seal up all of the areas exposed during a major house renovation. I trust that it is going to provide a significant increase in heating/cooling efficiency and great comfort for my family. The service was all very professional. They walked through the process, gave adequate explanation, and worked hard in a timely manner.
This was the 2nd time I use Great Northern Insulation with very satisfactory results. The the first time was for foam spraying my entire basement through the Union Gas Energy Rebate Program and most recently for applying blown insulation in the attic under the Green Ontario Fund Program.
Everyone at the company that I interacted with was very professional, informative and a pleasure to deal with, beginning with Bill who came out take measurements and provided me with an estimate, to the staff in the office who coordinated the scheduling, took care of the rebate program paperwork and payment processing etc., right to the employees (Dan, Henry & Desi) who completed the work in a timely manner and were also very contentious of the fact that they were working in the upstairs bedroom areas of my house and made sure that when they were done, everything was cleaned up nicely.
I have no hesitation in recommending Great Northern Insulation to anyone - their quality of work is good, their workers are respectfully, well trained and are happy to answer any of your questions and you will find their prices are very reasonable.
Right from the first call I made to Great Northern Insulation to the hand shake just before they left after the job, I was impressed.
Rob Adams was full of really good information about the product and the best way for me to proceed.
Pete and Jake, the two that came to do the work were very polite, informative and worked steady to get the job done. Two Great young men.
Stephanie and Marilyn on the phones were again full of information and helped me with decisions and payments. Very friendly on the phone.
I had my contractor come back to see the job and he too was very impressed with the product. He said that is the best insulation he has ever seen. He has been in cottage and house lifting for 30 years. He also said he will be telling anyone needing insulation about the product. He also took pictures.
100% Happy with the Whole job.
They did a quality job. I had them remove insulation and blown back into attic. Worked around our reno schedule for installation and kept me informed during the work. Have used them in our North Bay house as well. Good Job!
Sales Rep Matt Reesor arrived on time reviewed our attic and gave us our quote.
The 2 gentlemen who did the install were fantastic and afterwards vacuumed the entire area the work was done. Our only issue was the people who do the scheduling. We were told Mon. May 21 between 2-4pm no show and no call, we had to call the Tuesday to be told the work would be done Wed. 23 around 11am, we were then called and told they had a cancellation and that they would arrive at 8am well 8am came and went and so did 11 no show, no call. We had to again contact the office and the crew did arrive around 1pm, no explanation given. Other than this I would still recommend your service but would advise to be active in calling your office.
Great Northern Insulation did an amazing job. My home is about 18 years old, attic was sitting at about an R30 so topped up to an R60. Matt(our adviser) was very knowledgeable, air and offered options on what product/ R-rating we should go to. The crew were in and out in about an hour and a half. I highly recommend GNI and will definitely be using there services again!
We hired Great Northern Insulation to install blanket insulation in our basement. Ryan Hyndman arrived on time and was very efficient. He finished on time and cleaned up the area leaving everything as he found it.
We would definitely recommend this company.
Yesterday our attic was insulated by Matt Rittan, Phil and Hebron. They arrived promptly, completed the work quickly, expertly and efficiently and cleaned up the garage after they were finished. They took the time to answer questions, explain the product and were courteous and knowledgeable.
All of our contacts with Great Northern Insulation were positive ones - from our first inquiry call and their first visit to quote on the job, to the actual installation of the insulation.
They also provided the required information and forms for the government rebate.
We wouldn’t hesitate to recommend this company to friends and family.
I would highly recommend Great Northern Insulation for the following reasons:
1. Matt in sales was professional, courteous, and knowledgeable. Every step in the process was as he indicated to us before hand. His pricing estimates were fair and accurate. Best of all he was only a phone call away if I had a question.
2. The install teams again were knowledgeable and professional and did not do any short cuts! I am picky and the work they did was as per the contract (and maybe a little extra) and they left the job site as clean as they found it.
3. The administration team was friendly and efficient. They got the applications off to GreenOn the day they said they would...Thank you.
I was hesitant in hiring someone to complete the insulation for my basement after hearing stories from friends, but as soon as I completed the online request for quote and call back, I was met with incredible service. Matt answered the many, many questions I had prior to commitment and Great Northern Insulation was able to accommodate my dates in a small window and did an excellent job. I was on vacation when the work was completed and payment and service were seamless.
Two gentlemen arrived on time and were friendly and polite. They completed exactly what was scheduled and kept me informed as the day progressed. I am very happy with the workmanship and customer service provided.
First it is very reasonable price.
Second The appointment should be between 7-8am, but the technician came after 12 noon, when we called the office who told us the their truck was broken down, actually they had morning job in Hamilton. The should told us early so we don’t need to waste our time to wait.
Third the technicians they are nice and professional. But for the results which we have to wait to see in the winter time.
The team that came for the spray insulation was fairly professional, cleaned up after themselves.
They were supposed to show up in the morning, but I got a call about an hour before the scheduled time that they were having mechanical issues with their trunk and would not be able to make it till after lunch.
This did show up and finished the work as expected.
The team that came for the blown in cellulose was also fairly professional and completed the job to my satisfaction.
I would recommend GNI to anyone who asked.
We had our basement spray foamed by Great Northern Insulation. We loved the service and professionalism of work crew that had them come back a second time to complete the entire basement. Now the basement is air tight solid and worth every penny. Great investment great service provider. Very happy.
Thank you GNI for a great customer experience.
From your sales rep Matt taking the time to explain the process of what needed to be done and what I needed to do before hand, and also for his emails and calls for follow ups on any concerns we had.
Also to Shannan for the ease of scheduling and payment for the
Mostly I would like to thank your installers Tim and Jamie who worked under adverse conditions.Who knew it would be over 30 degrees in May!!!
They arrived on time and finished on time and cleaned up after completing the job.You wouldn't even know they were here.
Thanks guys for your hard work and dedication.
We are very pleased with the work done by Great Northern Insulation. The estimate and work was done quickly and neatly. They submitted our information to Green ON for rebate. Overall, we are very pleased and are looking forward to the difference in our heating bill this Winter.
My experience with this company and the staff was a very positive one. There were a few minor issues but they went out of their way to correct things.
Jason was very helpful in getting things set up as soon as possible to rectify the situation.
My phone dealings with Jason was very positive. He was very gracious and understanding. He gladly offered my a generous compensation for the error and time that was lost.
I liked the service provided by Great Northern Insulation because the installers arrived on time and explained what work they were doing. They maintained a clean working environment throughout the entire process.
A+ service. Crew was very friendly and took their time covering everything near the attic access. There is a noticeable difference on our second floor during the recent heat wave...definitely cooler than before. I highly recommend GNI.
We were VERY impressed with the crew that came to our house. We would highly recommend them to everyone. They were respectful and made to sure that they didn't leave a mess. They were friendly, knowledgeable, and really helpful - They helped fix one of our issues in our roof. A++++
Great Northern Insulation installed insulation in two properties and did an amazing job, both with the installation AND taking care of the GreenOn rebates. Will use them again on future properties. :)
The men arrived at the time that I was told they would and completed the work within an hour and half.
There were a couple of things that I wasn't to impressed with (not anything major):
-the hose had to come through a bathroom window which was ok but when they removed the screen from the window they just pushed it from the inside and it just dropped on the ground very close to where my car was parked
-I wasn't aware that the job would be so dusty but that's fine it is what it is but they only have a shop vac and straw broom to clean up after which doesn't work well on hardwood floors without possibly scratching them. I didn't expect them to clean up all the dust and pieces, just the area where the hose came into my house.
All in all they did a good job.
Dealing with Great Northern Insulation has been a pleasure. From first booking an inspection to the delivery of finished product all has been a very good experience. The employees of GNI have been very knowledgeable and helpful in providing product information, making suggestions of improvements booking installation and the processing of rebate.
The only problem I had was on installation day the truck was late by 2 hrs and I had to call to see where they were at. I was informed they were behind due to transportation issues. I would have appreciated a telephone call to advise me of the delay,rather than myself calling them.
Would highly recommend this company to family and friends.
We were very pleased with the professionalism that Great Northern Insulation showed when insulating our attic. They showed up when promised, were very clean and did the best that they could to minimize the dust in our house.
They seemed very qualified and like they knew their stuff. They completed the job in the amount of time that was promised.
My only worry now is that the Green On rebate comes through as promised but I realizes I'm filling this out prior to the completion of the grace period for this rebate.
