FAQ

Frequently asked questions

"How do I know if I need insulation?"

"Look for these signs: uneven room temperatures, drafts, high energy bills, or ice dams on your roof. Homes built before 1980 almost always need better insulation. Call us for a free assessment."

Is spray foam insulation worth the investment?

Yes — spray foam insulation is one of the most effective long-term investments for your home. While the upfront cost is higher than traditional materials, it delivers superior air sealing, reduces energy loss, and helps control moisture. Over time, this leads to lower utility bills, improved comfort, and even added structural strength. For many homeowners, the system pays for itself through energy savings and reduced maintenance.

How does the Mass Save rebate program work for insulation?

The Mass Save program helps homeowners improve energy efficiency by covering a large portion of insulation costs. After a home energy assessment, eligible projects can receive between 75% and 100% coverage, depending on the scope of work. At Thermal Core, we guide you through the entire process — from assessment to paperwork — making it simple and seamless to take advantage of the program and reduce your out-of-pocket investment.
