Took forever for us to decide to insulate our attic mostly because we had so much junk up there. But this group took everything away, put in new flooring and great insulation. We went from R11 to R42! What a difference. We set the thermostat to 60 at 9pm each evening but it never gets to that because the insulation does such a good job of keeping heat in. Also insulated where we had a frozen pipe situation and no frozen pipes this winter. Group very nice to work with.
