"Since we had squirrel damage on some electrical wiring in the attic, we hired them to first remove the old insulation so the electrician could more easily do the wiring repair. Cost more to remove the old stuff (old and worthless), but it saved $500 on the electrical work bill. After the electrical work was done, they came back and filled in the attic with R49. The guys doing the the removal and installation work were great, and it went quickly and efficiently. Terry was a good guy to work with for estimates and scheduling, and Brian for invoicing. Overall, we are very happy. Wish that work with all home contractors went this well."
