Wall Insulation in Fresno, CA
Thousands of older Fresno homes were built with little or no wall insulation. You feel it as cold walls in winter, hot walls in summer, and noise from the street. Masterguard retrofits wall insulation without tearing out your drywall.

Wall Insulation in Fresno
Our drill-fill-patch-texture process dense-packs Greenfiber cellulose into every stud cavity through small access holes. The cellulose resists settling, so you get complete, permanent coverage — not gaps that sag over time.
Dense-pack cellulose is one of the best retrofit options for Fresno's older plaster and stucco homes. It adds real R-value and noticeable sound dampening between rooms and from outside.
When we're done, every access hole is patched and textured to blend with your existing wall finish, ready for touch-up paint.
