"Attic Elite is BY FAR the most professional insulation contractor. When you are looking at a major purchase (over 10k) it's good to know the contractor isn't "flying by the seat of their pants", especially when asbestos is involved."

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

"I was extremely impressed with the service provided by Air Sharks, who replaced my aging furnace and damaged heat ducts. Elizabeth provided a detailed explanation in a friendly, professional and understandable way. Pricing seemed reasonable, and was 25% below a previous estimate. Daniel and his crew did a fantastic job removing and replacing the new furnace and the duct system in a very tight crawl space. They left the furnace looking absolutely beautiful and clean. I highly recommend them"
