"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

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

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