Insulation Company in Oakhurst, CA
Woolsey Attic Insulation is an insulation company serving Oakhurst, CA, and the surrounding Sierra foothills. What makes insulation work here different from the Valley floor comes down to elevation. At roughly 2,300 feet, Oakhurst homes face hard winter freezes and triple-digit summer heat, often in the same year. The housing stock reflects that: 1960s and 1970s vacation cabins with minimal original insulation, manufactured homes, and a growing number of post-Creek Fire rebuilds. Our two main Oakhurst services are attic insulation and spray foam insulation, each with its own dedicated page linked below. If you’re not sure which one fits your home, call (325) 240-5411 and we’ll talk it through.
Why Oakhurst Homes Are Different
Oakhurst sits in the Sierra Nevada foothills at an elevation that creates a genuine four-season thermal load. Winter nights routinely drop into the teens and 20s, with occasional snow. July and August regularly push past 95°F, and 100°F days are not unusual. That swing means insulation here has to fight heat gain in summer and heat loss in winter, a dual performance demand that low-elevation cities like Fresno rarely experience to the same degree. An attic that’s fine in Clovis in January becomes an icebox off Highway 41 in Oakhurst.
The housing stock adds another layer. Much of Oakhurst was built as summer-retreat cabins in the 1960s through 1980s, when insulation was an afterthought or skipped entirely. Manufactured and mobile homes are common. And the 2020 Creek Fire triggered a wave of rebuilding and permitting under current Title 24 energy codes, so fire-rated assembly compliance and upgraded thermal envelopes are now routine expectations on local jobs. Add in the second homes and short-term rentals being converted for year-round use, and you have a market where most attics and crawl spaces are decades behind what the climate actually demands. We see it every week on the roads toward Bass Lake: seasonal cabins with exposed crawl spaces and no ground vapor barrier, now running as rental properties. That crawl space becomes the first and most obvious energy failure.
Our Main Oakhurst Services
Most Oakhurst homeowners call us about one of two projects: bringing an older attic up to current standards, or air-sealing a post-fire rebuild or converted cabin with spray foam. Each service has its own Oakhurst page with full details and local pricing.
Attic Insulation in Oakhurst
Oakhurst attics run the full spectrum: blown-in fiberglass from a 1970s cabin reno, bare rafters over a two-bedroom mobile home, or brand-new trusses on a post-Creek Fire rebuild. The job usually starts with us measuring what’s actually up there, because “some insulation” is often not enough for a January night in the teens. In many older Oakhurst homes, the existing attic insulation has compressed, settled, or been chewed through by rodents, and the fix is a full removal and fresh install. Radiant barrier work is also common here, because summer attic temperatures above 130°F are routine. Attic Insulation in Oakhurst covers all of it, including what we charge per square foot.

Spray Foam Insulation in Oakhurst
Spray foam, a two-part liquid that expands on contact and seals gaps airtight, is the service we recommend most often for Oakhurst homes with crawl space problems or irregular attic shapes. Many older cabins on the Bass Lake side have open crawl spaces with zero vapor barrier, and owners converting them to year-round rentals find that no amount of attic work fixes a frozen floor if the crawl space is wide open. Closed-cell foam handles that directly. It also works well on post-fire rebuilds where current Title 24 air-sealing requirements are in play. Spray Foam Insulation in Oakhurst explains the difference between open-cell and closed-cell and what each costs here.

What pushes prices up in Oakhurst? Access. Steep lots, tight attic hatches, and cabins built onto hillsides all add labor time. A manufactured home with a low-pitch roof costs less to insulate than a 1970s A-frame with a 12:12 pitch. Whatever the job, you get a written price before any work starts. That’s the Kingswell Way, and it applies to every job in Oakhurst, no exceptions.
