"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"Installation of insulation went well; EZinsul was very thorough. However, there were some clumps of insulation and a thick film of fiberglass covered everything, despite their sweeping up to â industry standardsâ . Jacob & I talked; he came back and dusted to my satisfaction. I appreciated this attention he paid to my project. I would highly recommend EZinsul. Ruth Ann White"

"They came on time and the insulation looks well done. Didn't do a great job of cleanup - some old insulation around on the ground. They weren't prepared for the steep driveway and didn't have long enough tubing, so they had to improvise by using the neighbors driveway. Would be good for them to enhance their capabilities there."

Insulation questions, answered by experts

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.
