Spray foam +attic insulation fo new home

Great northern insulation installed foam and attic cellulose in my new house project. Spray foam was applied throughout main floor, on a cathedral ceiling spec and on cantilevered soffit areas. They also sprayed all ductwork in the attic space.

The installers were fast, thorough and clean. Minimal overspray (which was cleaned up after) and consistent application. Pricing was very competitive. Scheduling with the office was a breeze.

Thanks Great Northern Insulation for your work on this project!

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

Blown cellulose insulation in attic

Retained GNI to install insulation in attic. Their quote was competitive. The team of Tom, Logan and Emil were professional and courteous. Did a good job with site preparation and clean up.

insulation

~The salesman showed up when he said he would for estimate
~The workers showed up when they said they would
~They refused to complete the job until the site was prepared properly so they could do the job properly. They did not just go ahead to get it done and move on.
~They offered advice on additional work to improve insulation, and how to do it.
