    I have had Great Northern for three jobs now I wouldn't have any other kind of insulation in my house. They are always fast and very neat and clean up after they are down. They arrived one hour late this last visit but normally arrive on time.

    Everything from quote through to insulation was completed in the committed timeframes, thoroughly and professionally. The installation team was neat and tidy leaving no trace of their work other than a bunch of new insulation in our attic! Thanks GNI!

    Great service from the start with our quote to the end with the insulation. They were ready to go within days of our quote and were on time when scheduled. They used various tools to keep our house clean and cleaned up well after themselves. I would definitely use them again and recommend them to anyone who asks.
