Batt, Rolled or Reflective Insulation Install or Upgrade
We hired ThermaCore Insulation to remove our old attic insulation, air seal the attic, and install new insulation. Kamal and his crew were professional, honest, and easy to work with from start to finish. During the inspection, they found several air leaks and duct issues that other companies completely missed. They explained everything clearly, completed the work on time, and left the area clean. We noticed a big improvement in comfort right away. Great service, fair pricing, and quality workmanship. Highly recommend ThermaCore Insulation!

Blown In Insulation Install or Upgrade
We found signs of rodent activity in our home and after talking to several companies, we decided to go with ThermaCore insulation . We are incredibly happy with the work they have done. There was an active rat infestation in one of the attics and they acted quickly - cleaned and sanitized all spaces where rodent activity was found, pulled out all the old insulation out and cleaned, cleaned the duct work, and did a very thorough walkthrough of the home to find and close entry points (and there were a lot of entry points, sigh, Everyone I have worked with have all been professional, friendly, and knowledgeable - especially, Kamal and his professional team.

Blown In Insulation Install or Upgrade
We had an outstanding experience with ThermaCore Insulation from start to finish. Their team was professional, punctual, and extremely knowledgeable throughout the entire attic restoration process. They removed all of the old insulation carefully, completed a full sanitation treatment, sealed all rodent entry points, and professionally air sealed the attic to improve energy efficiency. After everything was prepared correctly, they installed the new insulation with great attention to detail and left the attic clean and organized. You can tell they take pride in their work and genuinely care about the quality of the job they deliver. The difference in air quality, temperature control, and overall comfort in our home was noticeable immediately. I highly recommend ThermaCore Insulation to anyone looking for honest, high-quality attic and insulation services. Five-star service all the way.
