Insulation Company in Hemet, CA
Woolsey Attic Insulation handles attic and spray foam insulation work across Hemet, CA, where the job almost always comes down to one thing: a home built for milder weather trying to survive a valley that bakes at 110°F and freezes in the 20s. The manufactured-home stock here, much of it dating to the 1970s through 1990s, brings a specific set of insulation failures we see over and over again. If you’re losing cooled air by June or feeling floor drafts by December, call us at (325) 240-5411 for a straight answer and a written price before anything starts.
Why Hemet Homes Are Different
Hemet sits deep in the San Jacinto Valley, and the geography does something most homeowners don’t fully appreciate until their first summer electric bill arrives. The valley traps heat and pushes temperatures to 108 – 112°F for long stretches, while winter nights routinely dip into the mid-20s. That’s an 80 – 90°F thermal swing between seasons, and it punishes insulation that was barely adequate when the home was built.
The housing stock compounds the problem. Hemet has one of the highest concentrations of manufactured and mobile home communities in inland Southern California. Many of these units still carry the original ceiling insulation, which was thin by 1970s standards and has since settled, compressed, or been torn apart by rodents and time. Under the floor, the belly board – the fiberglass batt wrapped beneath the chassis – often sags, shreds, or disappears entirely, leaving large gaps directly under living spaces. Coastal contractors rarely see this at scale. For crews working Hemet parks every week, it’s the bread-and-butter failure.
Tract homes from the 1980s – 2000s have their own issues: builder-grade attic insulation that met code minimums of the era but falls far short of what R-value makes sense in a valley this hot. The result in both housing types is the same: hot ceilings in summer, cold floors in winter, and an HVAC system running far more than it should.
Our Main Hemet Services
Two services cover nearly every insulation problem we encounter in Hemet, and each has its own detailed page written specifically for this city.
Attic Insulation in Hemet
Most Hemet attic work involves removing old, compressed fiberglass that’s lost its loft, then air-sealing the ceiling plane and blowing in fresh insulation to a depth that actually works for this valley’s summer extremes. In manufactured homes, ceiling cavities are shallow and often unvented, so material choice and placement matter more than in a standard stick-built attic. We walk the home first, measure what’s there, and give you a written number before any work begins. Details are on the Attic Insulation in Hemet page.
Spray Foam Insulation in Hemet
Spray foam – a two-part liquid that expands on contact and seals gaps airtight – works particularly well in Hemet’s manufactured and mobile homes, where the floor-to-wall seam and rim areas leak air constantly. Closed-cell foam also adds structural rigidity to older chassis units, which matters as floors flex over decades. It’s a bigger investment than blown-in fiberglass, but it addresses the air leakage that drives the worst of Hemet’s indoor temperature swings. See Spray Foam Insulation in Hemet for what the job involves here.
