Insulation Company in Kerman, CA
Woolsey Attic Insulation is the Kerman insulation contractor built for the San Joaquin Valley’s hardest-working homes. In Kerman, we’re not just adding fluff to attics; we’re undoing fifty or sixty years of Valley heat and Tule fog that has crushed and compacted original fiberglass into a thin, useless mat. Most Kerman homes – the ranch houses and manufactured homes that hold this town together – were never insulated to handle a 150-degree attic in July. That’s the exact job we do every week. Call (325) 240-5411 and we’ll tell you, in writing, what your attic actually needs before a single door opens.
Why Kerman Homes Are Different
Kerman’s housing stock tells the town’s story. Built mainly from the 1950s through the 1980s for the families feeding the raisin and almond harvests, these are modest single-story ranch homes and manufactured homes on pads – almost none of them built with the kind of attic insulation modern California building codes expect. The batt insulation that went in during the Eisenhower or Carter years has settled under decades of gravity and heat, been chewed through by rodents, and now often sits at R-value levels that barely registered as insulation even when new.
Then there’s the attic heat. A Kerman summer pushes daytime temperatures to 105 to 115 degrees. Up in the attic, where your insulation lives, it bakes toward 150 degrees and stays there for weeks. That kind of sustained radiant load doesn’t just make a house hot – it actively accelerates the breakdown of old fiberglass batts. Every summer you don’t address it, the remaining insulation gets a little more brittle, a little less effective.
And Kerman still has a surprising number of swamp coolers – evaporative systems that work on open airflow, not a sealed house. When a homeowner converts to central AC, the insulation requirement changes entirely. The attic now needs to support a tight building envelope: better venting, sealed penetrations, and insulation that blocks radiant heat instead of just slowing air movement. That’s a two-part conversation we have regularly in Kerman, and one that rarely comes up in the newer, AC-ready subdivisions over in Clovis or northwest Fresno.
Our Main Kerman Services
Kerman homeowners call us for two things above all else: attic insulation that actually survives a Valley summer, and spray foam that seals a house the way a swamp-cooler-to-AC conversion demands. Each service has its own Kerman page where we get into the real specifics, local pricing, and what the job looks like at your house.
Attic Insulation in Kerman
The classic Kerman attic job is removing what’s left of the original fiberglass – sometimes just a gray, papery layer two inches deep – and replacing it with blown-in insulation rated to modern standards. In a 1,200-square-foot ranch home, that often means the difference between an August bedroom that never drops below 80 degrees and one that actually cools. We also handle the manufactured homes that make up a large share of Kerman’s lots, where the roof cavity and belly board need a different approach than site-built construction. Attic Insulation in Kerman has the full breakdown, including what materials we recommend for low-pitch, radiant-heat-heavy roofs.
Spray Foam Insulation in Kerman
Spray foam – a two-part liquid that expands on contact and hardens into an airtight seal – is the insulation conversation that comes up most when a Kerman homeowner moves from evaporative cooling to central air. The house no longer wants open airflow; it wants a tight envelope that keeps conditioned air in and 150-degree attic heat out. Closed-cell foam does that job better than anything else on the market, and it’s especially useful in Kerman’s manufactured and low-roof homes where cavity space is limited. Spray Foam Insulation in Kerman covers the details, including what open-cell versus closed-cell means for your specific house.

What pushes a Kerman job toward the upper end is usually access: a low-pitch roof makes attic work slower, and rodent-damaged batts mean more removal time before any new material goes in. The Kingswell Way says you see the written price before any work begins. No door-step changes, no “we found something once we got up there” surprises.

What Kerman 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
