"Brayden and his crew were as friendly as a favorite relative! They worked professionally and neatly. And cleanup was complete and exact. The final walk down also proved to be encouraging as well, with everything put back in its place! I wouldn't hesitate hiring them again in the future ever! They were GREAT!!"

"I had someone come out to my home to take a look and they were very professional and answered every question I had. The install guys came a couple days later and they were both great and showed me the work they did and I was very pleased. So far I have noticed a huge change in my bill and will definitely be recommending to my friends and family!"

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.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

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.

Yes, insulating your pipes can reduce plumbing noises because it dampens vibrations and reduces the transmission of sound, making your home a quieter place. So if you've ever been annoyed by the sounds of water rushing through your pipes or the clanging noises when someone turns on the faucet, insulation can help.
