Insulation Company in San Bernardino, CA
Woolsey Attic Insulation is the San Bernardino insulation company that works with the city’s real conditions: 105°F summer afternoons, below-freezing winter nights, and a housing stock full of 1950s and 60s tract homes with original or degraded attic insulation. If your San Bernardino home has never had an insulation upgrade, you’re likely paying for comfort you don’t get and heat you don’t keep. Call (325) 240-5411 and we’ll give you a written price before any work starts.
Why San Bernardino Homes Are Different
San Bernardino sits at the foot of the San Bernardino Mountains, and that position creates one of the most thermally extreme spots in Southern California. Summer days routinely cross 105°F, driving attic temperatures past 150°F on the south-facing hillside slopes. At night, cold air drains off the mountain front through the Cajon Pass corridor, pulling winter lows below freezing. That swing means insulation here has to work against heat gain and heat loss with equal effort, which is a stronger return-on-investment argument than you’d make in Riverside or Ontario.
The housing stock adds another layer. Most of the city’s residential base was built between 1945 and 1975, wood-frame stucco construction with whatever minimal insulation the code allowed at the time, often R-11 batts or bare sheathing. Decades of deferred maintenance mean a large share of those attics still carry compressed, degraded original batts. Homeowners in neighborhoods along the alluvial fan north of downtown, places like Muscoy and the Verdemont foothills, tell us the same story: winter heating bills that sting and summer AC units that never shut off. The fix is usually air-sealing at the attic plane plus a real R-value upgrade, not just throwing more batts over the old ones.
Our Main San Bernardino Services
We install and service two types of insulation in San Bernardino, each with its own dedicated page covering local pricing, the job process, and what to expect.
Attic Insulation in San Bernardino
Most San Bernardino attics we open are running on 50-year-old fiberglass batts that have compressed to a fraction of their labeled R-value. An attic insulation job here typically means removing what’s failed, air-sealing the bypasses where mountain air leaks through, and installing fresh blown-in or batt insulation matched to Title 24 Climate Zone 10 requirements. Homes in the Verdemont foothills and other areas near the mountain front often need the air-sealing step more than anything else. Attic Insulation in San Bernardino has full pricing and process details.
Spray Foam Insulation in San Bernardino
Spray foam, a two-part liquid that expands on contact and seals gaps airtight, works especially well in San Bernardino’s older tract homes where the attic plane is full of unsealed penetrations. Open-cell foam fits vented attics common across the city’s postwar stock, while closed-cell handles the higher demands of south-facing roofs that bake under 150°F attic heat in August. We work with several major brands and match the material to your roof and county requirements. Spray Foam Insulation in San Bernardino covers the details and local cost ranges.

In San Bernardino, two things push prices up: severe attic heat that makes August and September work slower and more physically demanding, and the frequent need to remove failed original insulation before installing anything new. Whatever the number, you get it in writing before any work starts, and it’s the number you pay.
