Great Northern Insulation

Apr 2026

Matt and John did an excellent job with the spray foam insulation in my attic. They were very professional, thorough, and clearly took pride in their work. What impressed me the most was how carefully they worked around all the tight and difficult areas to make sure everything was properly sealed. They didn’t just spray the easy spots—they made sure the hard-to-reach areas, pipes, and corners were well covered so the space is fully air-sealed. The attention to detail and effort they put into making sure everything was sealed properly really shows. I truly appreciate the quality of their work and their professionalism throughout the job. I would highly recommend Matt and John to anyone looking for insulation work done right.

Aaron provided us with a prompt quote; Gracie & Harpeet were very professional and courteous. This is our 3rd property we've used GNI for our upgrade needs and would definitely recommend.
