Great Northern Insulation

Jun 2023

My daughter works for the gravenhurst branch and always told us that we should upgrade our attic as no updates have been done to the house since before we moved in. So Last year my husband and I upgraded our attic as we were dealing with a drafty house. We are doing a lot of updates to the house and insulation was one of them. The sales rep was very professional. I think his name was Bill Barlow. The two installers were fantastic. They arrived on time. They were very professional and worked very quickly and efficiently. I am very pleased with the service and would recommend Great Northern Insulation to everyone!

We hired Great Northern to insulate our new home in Bracebridge! Their workmanship and professionalism was excellent. We required follow up for a heat loss issue and Chris and his team made sure the problem was corrected. We can’t recommend this fantastic company enough!Liz and Ric Holder

Erin and Shawn from the Muskoka branch were super friendly and professional and the additional R value that they added to the attic will save me lots of $$$ on my heating bills this winter.
