After my eco-energy audit I had trouble finding a company that specializes in doing attics. Dominion was referred by a friend who has had then do his last 2 houses. I had their salesman Steve over from Dominion and he answered all my questions, even ones about bad reviews on this site, which is why I felt obligated to write in. I went with Dominion because of 2 reasons, my friends referral; and they didn't want any money down and Steve said payment is due upon completion, which to Dominion means, complete customer satisfaction, so do not pay until you are. The job went off without a hitch, I look and measured myself, 17.5", good enough to get my rebates. The auditor was around 2 days later and confirmed. Now just waiting for my money from the Eco program, wish the government was as efficient as Dominion.
