"Easy company to work with. In our large crawl space a few spots were missed. One call and the crew was back in 2 days to do touch up. Note that this was difficult work-lying on your back spraying above you with respiratory & eye protection so to miss a few spots might be expected as well as how insulation expands. They did great job removing old batt insulation Filled w mouse poop"

"Recently had my attic insulated by Best Homes. Chris and his crew were professional and very efficient with their work. They insulated my attic within a few hours and left my house cleaner than it was before they got there. I wouldn't want the job done by anyone else."

"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."

"The consultation went great. Cary came out and spent about an hour measuring and evaluating our basement. He left me with a quote the same day as well as my options. Although a little pricey we decided to go for it. The guys came out a few weeks later to insulate and were here all day. No issues there. However, the basement has not warmed up since and we spent quite a bit of money and were told it would be about 60-65° down there. It only increased by maybe 5° and still isn’t even close to 60/65°. I emailed the guy Cary who came out and was told he’d talk to his guys about it. No response. I had to follow up. Then he said he’d send someone out. Never got a call or anything to schedule it. Again I had to reach out. Weeks later he finally said he’d come out on 3/18/21 at noon. It’s now almost 1pm and he’s still not here. Their service was great when they wanted our money but now that we have paid, it seems we are not longer a priority and they don’t care to come fix whatever the problem may be. Very disappointing. We spent thousands of dollars and our basement still feels very cold!"

"They provided blown in insulation for my home. They were able to schedule an appointment quickly and showed up on time. Their price was approximately market price (not a bargain). They did a satisfactory job, but their cleanup left a lot to be desired and they had to quickly repair something that was accidently damaged during the blow-in process. The employees were nice and professional, but didn't seem to be experts in the field. Their office was helpful in answering questions and handling payment processing and energy tax rebate questions."
