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!

They were on time as I booked this appt 2 months ago, did the job. Forgot too ask some questions, will find out if they did a good job. When the energy auditor comes in too check their work

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

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.

team did a great job , very professional ,
special thanks to Eric for such a great clean up job.
Thanks Guys we already feel a difference in the temperature of the house.

~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.

Only good things to say about Mike (sell rep) and the crew that came to do the work.
Professional opinion and advice, adequate price (purchased through Costco).
The crew did very clean and neat installation.
At every step my questions were answered and followed through in a timely manner.
Would definitely recommend.

I was lucky enough to have Joel and Gabe come and help
With my home Insulation project. They were knowledgeable and offered suggestions and information for everything I requested. They even patched the drywall ! It was incredible. Then during install they noticed a hot water leak which explained my high water bill. Thank goodness I immediately called the plumber and had it fixed!
So
Thank you I
Will be toasty warm!
M I forgot to take a picture sorry!

The only reason that this review doesn’t get a zero or 1 star is that I will give Great Northern customer service some credit for trying to make our spray foam insulation job at our cottage right.

The spray foam work done deserves a zero or no stars. Our old cottage had exposed 2 by 4 walls and there was not a single cavity that the foam did not protrude beyond the studs, making installation of any wallboard impossible. On top of this despite stapling up plastic barrier (we know because we had to pull out hundreds of staples, some on unfinished parts of the cottage but also some in our floors, the wall quarter-rounds and even in some of the finished wood areas or the cottage) there was overspray everywhere, most significantly on our ceiling where we intended to leave natural wood with a whitewash finish. So GNI tried to make it right. They sent crews for 2 more days meaning we were displaced from our place and it required vacation days to be there. After two days of working with 2 people on the first day and 4 people on the second day with work involving what they call scarfing (sawing) the walls to remove excess foam and scraping the ceiling and then sanding the ceiling I asked the site foreman on day 2 if there were vacuuming the walls. He insisted that the crew would sweep and vacuum the walls. The did run one vacuum (they could have used three) and then wrapped up the job. Going back into our place and starting to put furniture back in place we realized there was bits of purple foam dust everywhere. My wife and I vacuumed with two vacuums for 2 hours on Saturday and another 2 hours on Sunday. Upon more correspondence GNI offered to come back to do more cleanup but I declined. At this point I no longer wish to be displaced from my place nor do I trust their quality of work. As I said to them, when a job is done this poorly it is almost impossible to make it right. My wife and I plan to do a complete wall vacuum with a brush attachment to try to remove as much of the loose foam as possible on our next trip to the cottage. Hopefully this will somewhat remedy the situation until we can drywall.

Did GNI attempt to provide good customer service? Yes. Did they do the job with any sort of quality? No. Would I recommend them? I leave that to your judgement.

From the very start of the process to have the property insulated, sales to vapour barrier to the installation things were seamless. Along the journey there was constant follow-up to ensure things were moving forward to my satisfaction and timeline.

If I had one complaint it is that I have none. Special thanks to Angelo and the tallest man on stilts Frank! Great Job!!
