I received a quote from Great Northern Insulation and was pleasantly surprised at the price. The installers, Devon and Mark were nice young gentlemen who did a great job. They were courteous and professional. the job they did was excellent and I would recommend GNI to anyone thinking of insulating an attic.

I had draft issue with walkout basement. I had estimator come out and give me advice and estimate on options. I was able to schedule easily and crew that came to do work were professional and tidy. Basement temperature is much better after getting one wall done. I am looking at getting them back to do portions of other walls.

From sales and purchasing to install these guys very courtious and respectful to our needs. After completion I was asked to check their work....when they left there was no mess....well done.

We are very pleased with the whole experience with Great Northern Insulation. The people we dealt with were polite, efficient and took great care while working in the house. I am impressed at the team effort from start to finish. It was nice to start off with a great informative website and then have staff who were solidly behind the messaging. I now have "the peace of mind" that our attic insulation has been very well looked after.

We renovated our basement and needed to insulate the concrete foundation. We called GNI, there was great service as far as time it took to get is a quote. The team was accomodating with the dates so we went ahead. Great work, very happy.

Was very pleased from start to finish. From online inquiry to on site inspection and quote (by John) to day of installation (by Phil and Tom). All crew members were professional, clean and courteous. Very pleased with care of installation and clean up. Thank you.

I Can say , a very efficient and professional company to deal with, prompt, sevice providers where knowledgable on the work they where gong to do, provided advice on attaining better air circulation in attic, cleaned up after work was done. And I would highly recommend them to anyone I talk to. regards tim

We recently hired Great Northern Insulation to insulate an attic. The workers were on time and very professional. They were careful not to damage the freshly painted walls and did an excellent job cleaning up after the job.

Booking and getting a quote was fast and easy as was scheduling. Work occurred sooner than expected and payment was also a breeze. Used a combination of phone and online. Guys onsite were Tom and Brian and were punctual, polite, and clean. Dealt with parking issues like champs!

Our attic is a loft and attic in one, GNI came in with a combo of spray foam, added vents and topped up insulation. Great crew and service and now my home is much more efficient. Appreciate the work and the clean-up.
