Insulation Company in Mendota, CA
Woolsey Attic Insulation is the insulation company Mendota homeowners call when their attic stops doing its job. We specialize in attic insulation and spray foam insulation, nothing else. Mendota’s older homes, flat valley heat, and widespread use of swamp coolers mean the wrong insulation approach fails faster here than almost anywhere in the Central Valley. If your cooling bill has climbed and your house still feels hot by 2 p.m., call (325) 240-5411 and we’ll give you a straight answer.
Why Mendota Homes Are Different
Mendota sits flat on the San Joaquin Valley floor with no hills to break the heat. Summer highs push past 108°F, and winter tule fog rolls in with nights dropping into the high 20s. The housing stock reflects the city’s agricultural roots: modest single-family homes built from the 1950s through the 1980s, many with original insulation that has settled into a thin, ineffective layer, plus a significant share of manufactured and mobile homes that need different insulation strategies entirely.
The biggest wild card in Mendota is the swamp cooler. A large share of homes here still run evaporative coolers instead of central AC because they cost less to operate. But swamp coolers pump moisture into living spaces, which means any insulation work has to account for vapor management in a way that fully air-conditioned homes in Fresno don’t. Get that wrong and you’re trading a heat problem for a mold problem. We plan for it on every Mendota job.
There’s also the funding reality. Many Mendota insulation projects come through LIHEAP and California’s Weatherization Assistance Program, administered locally through agencies like Self-Help Enterprises. That requires contractors who understand program documentation, income qualification, and the specific scope rules those programs enforce. We do.
Our Main Mendota Services
Mendota homeowners call us most often about two things: adding attic insulation to homes that never had enough, and sealing problem gaps with spray foam where air leaks are eating the cooling budget.
Attic Insulation in Mendota
Most Mendota attics we inspect have blown-in fiberglass or cellulose from the original build that’s settled to half its labeled depth. We remove or top it off, air-seal the attic floor, and bring the R-value up to what Mendota’s 108°F summers actually demand. Radiant barrier is often part of the recommendation here, because reflecting heat before it soaks into the insulation makes a measurable difference when the attic hits 140°F. Attic Insulation in Mendota has the full breakdown on costs, materials, and what a typical job looks like.
Spray Foam Insulation in Mendota
Spray foam is a two-part liquid that expands on contact and seals gaps airtight, and in Mendota it earns its keep by blocking both heat and the moisture that swamp coolers push into the home. We see a lot of older Mendota homes with open wall cavities and unsealed eaves where air moves freely, and closed-cell foam stops that transfer cold. When applied correctly with vapor conditions in mind, it also resists the condensation problems that Mendota’s humidity profile invites. Spray Foam Insulation in Mendota covers what to expect if you go this route.

What pushes cost up in Mendota is attic depth and access. Older homes here often have low-pitch roofs with cramped attics, and removing decades-old settled insulation takes longer than a clean new-build job. Whatever the number, we give you a written price before any work starts, and that number doesn’t move.

What Mendota Customers Say
"Insulation job was done well. Scheduling took a little longer than I'd have liked, they were booked out a couple weeks. But once they came it was quick and the house is cozier."
- Felicia Grant"The guy didn't try to sell me on foaming the whole house. He said the attic was where I'd actually feel it and left it at that. Honest, and he was right, our bills dropped."
- Angela Ruiz"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
