"I've used Thermal Comfort a few times in the past to insulate entire homes, but this time I had a small job. Although this was a small job, they didn't treat it as one. From the start, I called Dason and he came to my property right away to look at the scope of work. I told him I'd like to get the work done ASAP. Although they were busy he squeezed me in, I was on his schedule within a week. The two techs, Randy and Walt were professional and got the job done in a timely manner. I will continue to use Thermal Comfort for my spray foam needs."

"I requested an estimate for blowing insulation into my attic. Jim came out once to do an assessment, and offered a reasonable estimate. We scheduled installation. He returned on my request after I removed the existing insulation to reassess the attic. It was determined that there was already insulation blown under the floor, and Jim stated that he would not recommend any further work. Jim did not charge me for the multiple visits for assessments, and was very gracious about the necessity of canceling. I would recommend his services without reservation."

"Tyler was the first to respond to an Angi List search, came the next day, and told me that my attic insulation, while not perfect, wasn't in need of adding more. I appreciated his honesty, even at the cost of losing a contract. I recommend this company based on honesty."

Insulation questions, answered by experts

Yes, many professionals offer insulation options, such as insulated siding (including insulated metal siding), to improve your home's energy efficiency.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

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.

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.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.
