My experience with DeVere Insulation was positive from start to finish. They were clear and detailed in their written proposal about what they were providing and the costs. The crew got the big job done efficiently – insulating the attic and the basement and putting in two exhaust fans. And at the end, I noticed I had forgotten to say I wanted the attic insulated over the garage, and the guys stayed extra time to get that done too, even after a long day.
