"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

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.

The lifespan of insulation depends on the material type. Fiberglass can last between 80 and 100 years, but it is important to start checking it around the 15-year mark. Spray foam has a lifespan of up to 100 years, and mineral wool can last up to 100 years. Cellulose, an eco-friendly option, has a lifespan of 20 to 30 years.

When installing metal siding, a high-quality house wrap is considered the best protection against condensation and moisture infiltration. House wraps can increase a home's efficiency significantly. However, a house wrap is not a replacement for a vapor barrier because it can be permeable when moist air passes through siding. This is why it's essential to follow manufacturer instructions for insulating siding when installing new siding.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.
