"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 really liked CT Basement systems. The sales rep walked me through the process of the basement SaniDry I had installed. When the installer came it turned out that I didn’t need all of the duct work and I was able to save a few hundred bucks. The installer was very professional, neat and helpful . I definitely will hire this company again. Customer service even followed up with me a few days later and had to remind me to register the system (good thing because I had forgotten)."

Insulation questions, answered by experts

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

Insulation can be easy to install, depending on the condition of your walls, but there are many safety considerations and potential challenges involved. For example, most types of insulation are made from materials that can cause irritation if inhaled or if they come into contact with your skin. Additionally, installing insulation incorrectly can actually make moisture issues in your home worse.

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.
