Painless Overall

They came in, did what they had to do in a matter of an hour or two at most and left. Didn't leave a mess and were overall professional and polite.

Cottage floor insulation

Great Northern did an outstanding job- from the initial assessment/quote that Ian did, to the finally spraying, and office responsiveness - professionally done, with extra effort by the install team to access those difficult to reach spots! we couldn't be happier ... R. Guest, Kahshe Lake

insulation

I found that the two guys who did the insulation were very friendly, professional and efficient. They did their work effectively. It took approximately four and half hours for them to do their job. I would recommend them. The sales man was very friendly and informative. Although I had to call back to get the installation dates. They did not call me, I called them.

Great Northern Insulation Delivers As Promised

Great Northern' s sales rep Phil gave me excellent advice when I called for a quote to ensure that I was getting competitive quotes, I was getting estimates that met the building code. Other competitors were not as straight- forward on doing a job that would meet the code; a building permit is required in the Kawartha Lakes.
Northern's team arrived at my cottage on time, set up quickly and got to work. They kept a clean worksite and finished the job in our crawlspace in about four hours including a cementatious layer. Very impressed with their staff and the quality of their work. Team showed me how density was tested as a reassurance that the job was being done well.

Kitchen Renovation

I wanted to comment on the work your guys did, foam spraying my kitchen walls last Friday. Firstly, they arrived on time (maybe 5 minutes early), then they asked if they needed to remove shoes before entering my home. They sized up the job, did prep work to cover windows, doors etc. They sprayed the foam, giving me at least 3 inches of depth, then cleaned up after themselves before saying goodbye. They were done in about 2 hours and did excellent work. I was very pleased with their work and would recommend you to others.
