"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."

"Every person that came into our home from Tri-County was very professional and respectful. They covered everything with plastic before removing the insulation and again when blowing it back in. They cleaned up and disposed of the plastic, vacuumed the attic and cleaned up after themselves such that you would never have known they were here. The job of sealing the attic was done so well that the inspector made a comment that he had never seen a job done as well as this and ask who had done the work. He gave them very high praise.
The salesman we had, Bryan Zailer, was very knowledgeable and helpful. He would call back immediately if we had a question and stop by to check on things. I would highly recommend Tri-County to everyone for their insulation needs."

"We had an inspection and we had to replace the insulation in the attic. We were able to get a good deal from this company after we reached them via a referral.
The work that they did was very good and professional. there were several employees at the house for the 2 days work that they did. We do recommend this company for any insulation replacement that you may need.
