Attic insulation

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.

Basement Insulation

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.

Attic Insulation Upgrade

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.

Attic insulation

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.

Great job blowing in cellulose

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!

Great Service

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.
