"Made a mess, insulation droppings on the floor and covered up electrical wiring and junction boxes. Used this in an unfinished basement and it caused problems when it came time to finish."

"We contacted Angie’s List for recommendations for Blow-in Insulation to refresh older insulation in our attic. Three companies we recommended to us. Two phoned the next day. I never heard from the third. I told both I was gathering information and would call to schedule an estimate. I called and scheduled two companies, including USA Insulation, to come make an estimate. One company called one minute before scheduled and wanted to re-schedule. Chris from USA was on time. We were pleased with his offer and accepted. He scheduled the installation for the next day. William and his helper arrived, set everything up, and went to work. I checked regularly and photographed the attic. When they were through, they thoroughly cleaned the area. We were quite pleased. Shortly after completion, Michael, a company inspector, arrived to check the work. I would give the company an A+."

"Estimate was fair and Warm Home was available to do the job two days later so I enlarged my scope to address other needs. Plastic was put down to protect carpets. On completion, I was pleased with the quality of their work and clean-up. Satisfied customer. I'd call them again without hesitation."

"It was a small job. They sealed the vents to the crawlspace, then, since there was already solid insulation panels on the walls, put a vapor/moisture barrier, in the form of a tarp, 4 feet wide and as long needed, completely around the crawlspace. It was then sealed to the walls with "nails" and adhesive. This seals the wood frame of the house from the 'Outside", the ground, which is the floor of the crawlspace. A 20 mil thick, quite heavy, "floor" was installed, also in the form of a tarp, It went up the walls about 3 feet and was taped to the 'tarp" on the walls, using a tape made for this application. The piers were wrapped with the same stuff and taped to seal the inside from the outside. the "floor" is also a vapor/moisture barrier, but, heavy enough to walk on if needed. This basically makes the crawlspace another room, rather than the outside. Our house is one year old and was already getting mold on the floor joists. Since the air in the crawlspace will now be heated in the winter and cooled in the summer, just like the rest of the house, the mold and cold (52 degrees) floors we experienced last winter will hopefully be eliminated. We shall see when dumb winter gets here."

Insulation FAQs, answered by experts

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

No, you shouldn’t wrap a towel, old T-shirt, or other porous fabric around your faucets. These materials absorb water, which can make your faucet more likely to freeze. Instead, you want to use waterproof, insulative covers that can seal tightly around the spigots for the best protection against frozen outdoor faucets and pipes.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

Yes, professionals install and upgrade insulation for all home or business areas.
