"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."

Drywall Insulation FAQs, answered by experts

There are some instances when you can use extra drywall in your garden. Ideally, unused scraps of new drywall are best for amending soil without the concern of additional chemicals or mold. However, drywall with paint, mold, or potential asbestos requires specialized disposal by a professional and should be kept out of your garden.

Through expert matching of texture and paint for an invisible repair.

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.

You may need to replace drywall because of smoke damage. If the drywall is covered in soot, you may be able to clean it, but it will require a lot of time and effort. You could spend hours cleaning the drywall only to find there is more damage and it needs to be replaced anyway. It’s usually easier and safer to remove the smoke-damaged drywall and replace it.

Plaster walls typically last between 30 and 70 years, but depending on the quality of the materials and the moisture levels in the building, they can last for over 100 years. With expert application and consistent maintenance, plaster can even last for centuries. To extend its lifespan, it is important to have the plaster professionally installed, address any water damage promptly, and repair small cracks as they appear. Regular inspections by a professional can help identify and address concerning cracks before they become significant issues.
