Insulation Company in Bloomington, CA
Insulation work in Bloomington, CA comes down to one fact: this unincorporated San Bernardino County community sits in the floor of the Inland Valley, where summer attic temperatures routinely pass 150°F and the housing stock from the 1960s through 1980s was built to standards that now fall far short of California’s Title 24 code. Most Bloomington attics test at R-8 or below, while Climate Zone 10 requires R-38 or better. That gap is why so many homeowners call us about attic and spray foam insulation. Woolsey Attic Insulation brings written pricing, background-checked crews, and the Kingswell Guarantee to every Bloomington job. Call (325) 240-5411 for a free estimate.
Why Bloomington Homes Are Different
Bloomington’s housing stock leans heavily toward single-family ranch homes built between the 1950s and 1980s. Because Bloomington is unincorporated, those homes were built under San Bernardino County jurisdiction, not a city building department, and the inspection oversight was lighter than what incorporated neighboring cities had. The practical result: many of those attics originally got R-11 fiberglass batts or less, and decades of settling, rodent activity, and simple heat degradation have pushed effective performance even lower. We routinely open Bloomington attics and find insulation that measures at a fraction of what the label once promised.
There’s another layer here. Bloomington is in the San Bernardino Valley basin, a geography that traps radiant heat. Summer highs above 108°F are common, and that heat-sink effect is far more punishing than what you’d find 50 miles west in coastal LA markets. Southern California Edison bills in July and August tell the story. When an attic is under-insulated in this kind of climate, the air conditioner runs almost constantly, and the temperature differential between attic and living space works against the house all day, every day.
Permits matter too. Because Bloomington is unincorporated, insulation permits run through San Bernardino County’s building department rather than a city office. Out-of-area contractors who don’t know the county’s submittal process and inspector scheduling often stall jobs by days or weeks. Our team coordinates Bloomington permits through the county the right way, so the inspection doesn’t become the bottleneck.
Our Main Bloomington Services
Bloomington homeowners call us about two insulation services more than anything else: attic insulation and spray foam insulation. Each has its own dedicated page, linked below, with full pricing, local details, and what to expect.
Attic Insulation in Bloomington
Most Bloomington attics we see were built with far less insulation than today’s code requires, and the valley heat turns that shortage into a monthly utility bill problem. Attic insulation work here means removing or topping off old, settled material and bringing the attic to R-38 or better, which is what California Title 24 demands for Climate Zone 10. We work with brands like Owens Corning and Johns Manville, and we give you a written price before any work starts. You can see the full breakdown on our Attic Insulation in Bloomington page.
Spray Foam Insulation in Bloomington
Spray foam, or a two-part liquid that expands on contact and seals gaps airtight, is a strong fit for Bloomington’s older ranch homes because it addresses both insulation and air sealing in one pass. The valley heat finds every crack, gap, and opening in an attic, and spray foam closes those paths in a way that batts alone can’t. We install open-cell and closed-cell foam using materials from brands like Demilec and Icynene. Get the full picture on our Spray Foam Insulation in Bloomington page.

Most Bloomington service calls get same-day or next-day response.

Because Bloomington is unincorporated, permits run through San Bernardino County’s building department, not a city office. Some insulation jobs, like simple top-offs, may not require a permit, while structural or spray foam roof deck work often does. We handle the county submittal and inspection scheduling for you, and we’ll tell you up front exactly what your job needs.
Yes, and we see this regularly. Bloomington’s older homes often test below what Title 24 now requires, and that gap shows up on energy audits during resale. Bringing the attic to R-38 or better closes that compliance gap and often cuts the visible utility bill enough to be a selling point on its own. The written Kingswell Guarantee transfers with the work, too.

What Bloomington Customers Say
"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"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
