Complete Insulation Services for Your Home
Professional ThermoShield Insulation service — flat-rate pricing, done right.
Attic Insulation
Top-ups and full attic installs to the R-value Texas heat demands — blown-in cellulose, fiberglass, or hybrid packages sized for your home.
Spray Foam
Open- and closed-cell spray foam for attics, crawlspaces, and rim joists — air seal and insulate in one high-performance system.
Blown-In Cellulose
Dense, even coverage that settles into gaps and around framing — fire-resistant, sound-dampening, and ideal for Central Texas attics.
Wall Insulation
Dense-pack cellulose and cavity fills for exterior walls — quieter rooms, fewer drafts, and better comfort without a full remodel.
Air Sealing
Seal attic penetrations, can lights, top plates, and ducts so conditioned air stays inside and dust stays out.
Energy Audits
Walk-through assessments, thermal imaging, and prioritized recommendations so you invest where it actually pays back.
Fixed in 4 Simple Steps
No runaround. No hidden charges. Just fast, professional insulation service from call to completion.

Our upstairs stayed 10 degrees hotter than the rest of the house all summer. ThermoShield added blown-in cellulose, sealed the attic hatch, and the difference was immediate. Flat-rate quote, clean crew, 5-year workmanship. Highly recommend.
