"Prompt service and good work. The drilled holes in the stucco and the patch work was excellent, can't easily see the patch, if at all in some cases. The only negative is that since they finished after dark, the cleanup wasn't as good as I would have liked."

"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!"

"Attic Elite is BY FAR the most professional insulation contractor. When you are looking at a major purchase (over 10k) it's good to know the contractor isn't "flying by the seat of their pants", especially when asbestos is involved."
