Great Northern Insulation

Punctual, courteous, professional and tidy would describe our recent insulation upgrade experience with Mike, Bill & Matt from the Durham Port Perry Branch. I would highly recommend this company for your insulation needs.

Had an excellent one-on-one visit with the estimator. He gave us a lot of options and was very friendly. They weren't the cheapest of the three companies that we got estimates from, but were definitely the most professional and we felt right giving them our business. They were kind of busy in terms of scheduling a crew to come, and we ended up having to split up their work over two days when it could have been done in one, but otherwise no criticisms.

Very polite, professional, great personalities and hard working men. Having the attic done will add great comfort to our home as well as value.
Thank you

VERY HAPPY WITH THERE SERVICE AND FRIENDLY STAFF WITH TERRIFIC RESULTS. ALSO VERY HAPPY FOR THE HELP WITH GETTING A GOVERNMENT GRANT TO HELP THIS GET DONE , THANKS A BUNCH :)

I saw them at the home show and really like what they had to say. They came and gave us a quote and we booked them to come out. They came on a 38 degree day and I felt bad on how hot it was. They did such an efficient job and vacuumed and left everything cleaner than it was. Matt and Brent did a fantastic job. Thanks

Just wanted thank Great Northern Insulation and your crew of Erin and Ross who were here this morning and did an outstanding job. They answered any and all question I asked. They were very pleasant and polite as they went about their work. They cleaned up better then I would have and that's really appreciated. I have to say that this was probably a very tough job especially in this heat and in such a confined space. Again I want thank GNI for a job well done, I will definitely recommend you to anyone who asks about insulating a home.

Bill,Matt,and Kyle were very pleasant to deal with. Very pleased with them and the work they have done. Would certainly recommend Great Northern Insulation to family and friends . Thank you

Decided to gut and renovate the basement in this home. Chose to use GNI because spray foam is the preferred material in this application. 3-person crew was well informed, courteous, prompt, and competed the job quickly with a good cleanup-up for a messy material.

Just had our basement insulated by the folks at GNI. Very pleased with the entire process i.e., initial inspection, estimate, application and final results. The crew that performed the work were polite, professional and very clean. After completing the work, they took the time to review the job site with me to ensure that I was completely satisfied. I've used the services provided by GNI on a couple occasions in the past and I've never been disappointed. I would highly recommend the folks at GNI for all your insulation needs,,,,, you won't be disappointed.

I would definitely recommend Great Northern Insulation. I can't remember the names of the two guys that did the work, but the sales rep. I dealt with was Angelo. They were punctual, did a great job & left my basement nice & tidy. I'm hoping for a much warmer & dryer cottage this winter!
