Bob, the owner of Northwest Insulation did the installations. Bob was punctual in his time commitments, and professional in his work ethic, as well as being a very pleasant person to deal with. He paid close attention to all details, including not only those required for a first-rate completion but also corrected corollary items that were not in the agreement. These included replacing a broken trapdoor, going to Home Depot for shingles to match those damaged by the installers of the replaced fan, and repairing a wrongly installed can light, all with no additional fee. We couldn't be more satisfied and would certainly recommend Bob and his Northwest Installation Company.
