cellulose upgrade to our attic insulation

The team of 3 arrived a little early... no problems. They put protection over anything that their hose might chafe and went to work. Apparently, our attic was 'easy to do' because of the older roof joist pattern. They were in and out in less than 2 hrs... 18" full depth.

Very personable and professional. two were experienced, and one was a bit of a deer in the headlights. They treated him well!

Would be my pleasure to recommend.

Basement spray foam

Very satisfied with the work performed by Great Northern. And the price is super competitive as well. The labourers left the area clean and tidy. I couldn't be any more happy with this job

Basement spray foam insulation

Our basement was really very drafts and cold so we contacted this company and had it spray foam insulation. Huge difference. We now have a warm basement. The company was very good and reliable to deal wth. The workers very professional. Couldn’t be happier!

Adding home insulation

Your crew working at 752 Walsh Street, Kincardine on December 4/19
arrived on time and performed exceptionally well. Even with a difficult access to our lower attic, they found a way, completed job in both attics successfully and left the house completely clean.
Nice work guys!

Jerry Dvorak.

Another great job by GNI

Like the consensus here among reviewers...Great Northern Insulation provided high quality work time and on budget. Would recommend for sure.

We selected GNI over some cheaper companies and sure glad we did.

Insulation installation

My home was approved for retrofit work under the Union Gas Home Weatherization Program - attic insulation, wall insulation with dense pack cellulose and comprehensive air sealing. Bryan, Jesse and Jeremy from Great Northern Insulation did the work.

Small Job Done Well

I had a small job done, just spray foam insulation around my basement joists, and under the soffit of my porch to warm up my son's room. Very happy with the job, the guys who did the job, and the warmer home.

Cottage and Garage Upgrades

GNI just finished a very large job to update our cottage and 2 new garages.

All 3 crews were very professional, neat , tidy and organized. The quality of work was excellent. I was especially happy to see very clean and well organized trucks...I knew the crews would likely be efficient.

I highly recommend GNI
