Who We Are
There's no shortage of insulation companies in Waco. Here's why thousands of homeowners call us first.
Locally Owned Since 2012
ThermoShield Insulation was founded in Waco by Brooke Lang, a Waco native and lead insulation specialist with 14+ years in the trade. We're not a franchise — every decision is made locally, every call is answered by someone who lives here.

Every installer on our team is background-checked, BPI-aligned, and bonded & insured. We treat every attic and living space with the same respect we'd want for our own families.
