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.

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!
