"Thermal Comfort exceeded my expectations for scheduling my project, and the quality of their work is excellent. They did a great job of protecting everything prior to application, and the cleanup was done well. As a retired architect and professional engineer, I expect and watch for quality, and was very pleased with this company. I recommend this company to anyone requiring a foam insulation project of fine quality and a good value."

"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."

"Was very happy with the work they did insulating my cathedral ceiling. They were very polite, organized and cleaned up after they had finished working. I could not get all of the old insulation out in some spots and there were some clips that needed to be removed. They took care of that for me, which I greatly appreciated. Great company to deal with. Also, thought their pricing was good."

Customers say: Quick response

"Specific project was attic, dense pack, and foam insulation. Very clean, friendly, and professional crew. Took the time to explain what they were doing, why, and what was wrong with what they found. Did a Focus on Energy assessment along with this work, recommended by Premier North, to make sure we let the science dictate the work. Very impressed with my overall experience."

Insulation questions, answered by experts

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.
