Insulation Company in Riverside, CA
Woolsey Attic Insulation is the insulation company Riverside homeowners call when summer attic heat turns the upstairs into an oven and winter nights leak warmth through the ceiling. Riverside sits in California Climate Zone 10, one of the most thermally demanding inland designations under Title 24, where summer attic temperatures routinely hit 150°F or higher. Most tract ranch homes built during Riverside’s 1950s-1970s suburban boom left the factory with 2-3 inches of blown fiberglass, if that. We’re the team that fixes it. Call (325) 240-5411 and a live person answers, any hour.
Why Riverside Homes Are Different
Riverside’s housing stock tells a specific story. When the citrus groves declined and commuter families arrived in the 1950s and 1960s, builders put up tract ranch homes fast. Attic insulation was an afterthought – often just a thin layer of blown fiberglass that has since settled and compacted. Walls were 2×4 with no insulation at all. The historic core near downtown and the Mission Inn district adds another layer: pre-1940s craftsman and Victorian homes where homeowners want to insulate without disturbing original wood lath and plaster. That’s a recurring Riverside challenge.
The climate makes it worse. The Inland Valley location creates a temperature swing coastal cities never see – summer highs above 105°F and winter lows that periodically dip to near-freezing. Insulation here has to work hard in both directions. The basin geography traps radiated heat overnight, so a poorly insulated Riverside home loses its cool well before dawn in a way a Santa Monica home with identical insulation would not. We spec jobs for this reality, not for a generic California climate.
Our Main Riverside Services
Two jobs account for most of the calls we take from Riverside homeowners. Each has its own dedicated page with full details.
Attic Insulation in Riverside
Most Riverside attics need more than a top-up. The standard R-38 attic insulation without a radiant barrier performs significantly worse here than in neighboring coastal markets, because Riverside’s basin geography and dark composite roofing push attic temperatures to 155°F on a 105°F day. We inspect what’s up there, tell you honestly what it’s doing, and write a price for the fix before any work starts. Learn more on our Attic Insulation in Riverside page.
Spray Foam Insulation in Riverside
Spray foam – a two-part liquid that expands on contact and seals gaps airtight – is a strong fit for Riverside’s 1960s-70s slab-on-grade tract homes in neighborhoods like Canyon Crest and Magnolia Center. Those homes often have no under-floor insulation, and open-cell foam in the attic can cut the heat gain that makes upstairs rooms unusable in August. See the full breakdown on our Spray Foam Insulation in Riverside page.

What Riverside 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"Spray foam in the crawlspace and new attic insulation. They wrote up the whole price and the two jobs came in exactly as quoted. Floors upstairs aren't freezing in the morning anymore."
- Nathan Pruitt"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."
