Why Fresno Trusts Masterguard
40+ Years of Experience
Serving Fresno and the Central Valley with insulation expertise since 1982.
Energy-Efficient Solutions
Right-sized R-values and air sealing built for Fresno's climate.
Skilled Local Crews
Trained, uniformed Fresno insulation professionals you can trust in your home.
Honest, Affordable Pricing
Upfront Fresno estimates with no hidden fees and no high-pressure sales.
Lower Bills, Higher Comfort
Fresno summers are brutal on AC systems. A properly insulated and sealed attic stops conditioned air from escaping and blocks radiant heat from baking your ceilings — meaning lower bills in July and a warmer, more comfortable home in January.
Built for Real Performance
Most energy loss in a Fresno home happens through the attic. We combine deep blown-in insulation, targeted air sealing around can lights and ducts, and proper attic ventilation so your home performs the way it should every season.
Proudly Serving Fresno
Proudly serving homeowners and businesses in Fresno and surrounding California communities — from Old Fig Garden and Tower District to Woodward Park, Sunnyside, and beyond.
What California Homeowners Say
Real homeowners. Real comfort. Real energy savings.
Masterguard re-insulated our attic and the difference was instant. AC barely runs midday now and our July bill dropped over $90. Crew was clean and respectful.
Removed old insulation that had rodent damage and installed fresh blown-in. Honest pricing and zero mess left behind. Would absolutely recommend.
Forty-plus years of experience really shows. They explained everything, recommended the right R-value for our home, and the install was flawless.
Added attic fans and topped off insulation. House finally stays cool upstairs in summer. Fair quote, on-time crew, professional all around.
Quoted us less than two competitors and did better work. The whole house is quieter and more comfortable. Real California pros.

Best contractor experience we've had. They sealed all the attic gaps before insulating and our bedrooms finally hold temperature overnight.
Masterguard handled our wall insulation upgrade during a remodel. Clean, fast, and the new rooms feel completely different — much more comfortable.
Used them for our small commercial building. Professional, fully insured, and finished ahead of schedule. Energy bills are noticeably lower.
After a roof leak we needed full insulation removal and replacement. They handled it all — even coordinated with our roofer. Top-notch.
Decades in business and you can tell. Knowledgeable, fairly priced, and the install made an immediate difference in comfort and noise.
