Insulation Company in Fresno, CA
Woolsey Insulation Fresno handles attic and spray foam insulation work across Fresno, from the Tower District up to Woodward Park and every neighborhood between. Homeowners here deal with a specific set of problems: summers that sit above 100°F for weeks, older attics where original insulation has settled flat, and a San Joaquin Valley sun that bakes low-pitch roofs all afternoon. We work with eight insulation brands, put a written price in your hand before anything starts, and answer the phone with a real person every time you call (559) 785-2658.
Why Fresno Homes Are Different
Fresno’s housing stock skews older. A large share of homes went up between the 1950s and 1980s, and they’re typically wood-frame with stucco or siding and low-pitch roofs. The problem, as any homeowner who’s peeked through the attic hatch in July already knows, is that most of these houses never got enough attic insulation to begin with, and what’s up there now has been baking and settling for 30 to 60 years. Original fiberglass batts in many Fresno attics have compressed to a fraction of their rated R-value, leaving ceilings that radiate heat into living spaces by mid-afternoon. Add in the valley’s poor air quality and the math gets simple: a better-sealed attic means less outdoor dust working its way into the house and a cooling system that doesn’t run nonstop from June through September.
Our Main Fresno Services
Most Fresno homeowners reach out about one of two things: getting more insulation into an underperforming attic, or air-sealing the whole assembly with spray foam. Each service has its own Fresno page with the full details, local pricing, and what to expect.
Attic Insulation in Fresno
Fresno attics get hot, and the older the house, the more likely the existing insulation has settled or degraded. Blown-in fiberglass or cellulose is a common retrofit here because it fills the gaps and gets R-value back up to what the ceiling actually needs. We measure first, explain what’s up there and why it’s underperforming, then give you a written price before any work begins. The full picture, including Fresno-specific cost ranges and how we run the job, lives on the Attic Insulation in Fresno page.
Spray Foam Insulation in Fresno
Spray foam is a two-part liquid that expands on contact and seals gaps airtight, which matters in a city where the gap between indoor air and outdoor heat can be 40 degrees or more. Open-cell foam works well for interior cavities, while closed-cell adds structural strength and a vapor barrier. For Fresno homes fighting heat gain through the ceiling plane, the air-sealing performance is what makes the difference. See local pricing and a full breakdown on the Spray Foam Insulation in Fresno page.

Brands We Service in Fresno
We’re material-agnostic in the way that matters: the recommendation comes from what a Fresno attic actually needs, not whatever happens to be sitting on the truck. Our crews install Owens Corning, Johns Manville, and Rockwool products, and we keep common attic insulation materials in local supply for faster turnaround. Take a look at our brands.

What pushes a Fresno job toward the upper end of these ranges is mostly attic accessibility, the amount of old material that has to come out first, and the square footage involved. What doesn’t change is the number after we hand you the written quote. Call (559) 785-2658 and we’ll give you a real price for your specific house before any crew steps inside.

What Fresno Customers Say
"Drafty old house that never felt comfortable. After the attic and some air sealing it's a different place. On time, clean, and the quote didn't change. Wish I'd done it years ago."
- Dmitri Kozlov"Our old insulation was flattened and basically useless. They removed it, cleaned up, and blew in new. Furnace isn't running constantly anymore and the first bill already showed it."
- Carl Yeung"Showed up on time, laid down protection on the floors, and were careful going into the attic. Explained exactly what they were doing and why. House holds its heat so much better now."
- Preston Hale
