I couldnt be happier with Great Northern Insulations work in my house. Jermaine, Ryan, and Gracie come to top up the extremely insufficient insulation that I had in my attic previously. From the moment they arrived, they took great care to protect my home from what could be a very messy job. After prepping the house, they quickly prepped the attic, protected the soffit vents, and boxed in the hatch with cardboard and foam insulation. Then Jermaine applied the insulation throughout the attic and it looks amazing. The end product will definitely improve our home and our comfort.
