Insulation Company in Bloomington, CA
Blown in insulation is the most common request we handle in Bloomington, where 1950s and 1960s tract homes sit under summer sun that pushes attic temperatures past 150°F. Most of these houses still carry their original fiberglass batts, now compressed and performing well below their labeled R-value. Brea Insulation has served Bloomington since 2014, and we carry eight manufacturer brands so the material gets matched to the house, not to whatever is cheapest on the truck.

Why Bloomington Homes Are Different
Bloomington sits in the Fontana-area basin of the Inland Empire, where the defining insulation problem is radiant heat gain, not winter heat loss. A stretch of 100°F days bakes asphalt shingle roofs until the attic becomes an oven, and that heat transfers into living spaces through ceilings, ductwork, and poorly sealed top plates. The dry, dusty air makes it worse. Batt insulation settles faster here than in coastal climates, and wind-driven dust infiltrates attics through gaps that were never sealed when the house was built.
The housing stock tells the story. Bloomington is dominated by postwar ranch and stucco homes from the 1950s through 1970s, most with shallow attics and original R-11 fiberglass batts that have collapsed over decades. Our technicians routinely pull out batts labeled R-11 that are actually performing at R-4 to R-6. There is also a growing share of manufactured and mobile homes in Bloomington’s parks, and those need different approaches entirely – underbelly insulation, roof cavity work, and blown in material that can reach around the framing without tearing panels off. The work here is overwhelmingly retrofit: upgrading thin or settled attic insulation, adding radiant barrier, or blowing new material over what is already there.
Our Main Bloomington Services
Bloomington homeowners call us most about two things: fixing failed attic insulation in older tract homes, and using spray foam to seal the gaps that let hot, dusty air pour into the house every summer.
Attic Insulation in Bloomington
Older Bloomington attics are shallow, hot, and often under-vented, which means standard batt replacement work rarely solves the full problem. We inspect for settled fiberglass, top-plate gaps, and ductwork sweating before recommending whether to remove and replace or blow new material over existing batts. Because summers here are so punishing, we often pair attic work with radiant barrier to reflect heat before it soaks into the insulation. See Attic Insulation in Bloomington for the full breakdown of what this job looks like in this market.
Spray Foam Insulation in Bloomington
In a climate where dust and 100°F air push into attics through every unsealed seam, spray foam’s air-sealing capability matters as much as its R-value. Closed-cell foam performs particularly well on the underside of Bloomington roof decks, where it blocks radiant heat before it reaches the attic. For older stucco homes with irregular framing and hard-to-reach cavities, open-cell foam fills gaps that batts can’t. We install Icynene and Demilec spray foam systems. Details are on the Spray Foam Insulation in Bloomington page.

Blown In Insulation in Bloomington
Blown in insulation is the workhorse for Bloomington’s aging housing stock. Most homes here were built with shallow attics and R-11 batts that have settled into a thin, ineffective layer after 50 to 70 years of inland heat and dust. Blowing new material over the top – or removing the old and starting fresh – gets those attics back to a real R-value without opening walls or tearing out ceilings. For manufactured homes in Bloomington’s parks, blown in cellulose and fiberglass also work well in roof cavities and sidewalls where rigid batts are impractical. We use GreenFiber recycled cellulose and CertainTeed fiberglass for most blown in jobs, matched to the attic and the homeowner’s goals. Learn more about the method on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic has batts that are compressed, dusty, or no longer fill the joist bays, and rooms directly under the attic feel hotter than the rest of the house.
What it costs in Bloomington
Blowing GreenFiber cellulose into an existing Bloomington attic typically runs $1,600 to $3,400 depending on square footage and target depth.
How we do it
We air-seal top plates and penetrations, then blow cellulose to the specified depth using a calibrated machine, checking thickness with depth markers as we go.
Blown In Attic Insulation
Signs you need it
Attic insulation measures under 6 inches deep across most of the attic floor, or the house was built before 1980 and the attic has never been topped up.
What it costs in Bloomington
A full blown in attic insulation job on a typical Bloomington ranch home ranges from $1,800 to $3,800, with exact pricing set by square footage and access.
How we do it
We either blow over existing batts after confirming they are dry and intact, or remove failed material first, then blow new insulation to R-38 or the depth the attic framing allows.
Blown In Cellulose Insulation
Signs you need it
You want recycled, higher-density material that slows air movement through the attic better than fiberglass, or you are insulating a manufactured home roof cavity.
What it costs in Bloomington
Blown in cellulose for a Bloomington attic averages $1,600 to $3,400, and the higher density often performs better in dusty, drafty old attics.
How we do it
We use GreenFiber cellulose, which packs tighter than fiberglass, and we blow it to the target depth while keeping soffit vents clear with baffles.
Blown In Fiberglass Insulation
Signs you need it
You want a lower-cost, non-settling attic top-up, and the attic is dry and sealed enough that fiberglass’s lighter density is not a liability.
What it costs in Bloomington
Blown in fiberglass for a standard Bloomington attic falls between $1,400 and $3,200 depending on depth and whether old material is removed.
How we do it
We blow CertainTeed fiberglass loose fill to the required R-value, fluffing it for even coverage and using depth markers to verify consistency across the attic floor.
Loose Fill Insulation
Signs you need it
Your attic has irregular joist spacing, shallow cavities, or tight corners where batts leave gaps and compressed edges.
What it costs in Bloomington
Loose fill insulation work in Bloomington generally runs $1,400 to $3,400, with the final number driven by attic size, access, and whether we remove old batts first.
How we do it
We blow loose fill to a consistent depth across the entire attic, working around trusses, vents, and ductwork so no section gets left thin.

How long does blown in insulation last in Bloomington?
Cellulose and fiberglass loose fill both hold their R-value for decades when the attic is dry and sealed, though Bloomington’s dust and heat settle batts faster than coastal climates. A properly installed blown in job should perform well for 20 to 30 years. Call (866) 858-4033 to have us check what is actually in your attic.
Can you blow insulation over old batts in a Bloomington attic?
Yes, as long as the existing batts are dry, mold-free, and not compressed to the point of failure. We inspect for dust infiltration and moisture before recommending a top-up versus full removal. Call (866) 858-4033 for a free attic assessment.
Brands We Service in Bloomington
We stock and install certain manufacturer lines specifically because they handle Bloomington’s heat and dust well: GreenFiber cellulose for dense, air-slowing attic coverage, CertainTeed fiberglass for budget-conscious top-ups, and Icynene and Demilec spray foam for air sealing in hot attics. Parts and materials are ordered direct from manufacturer distributors, so Bloomington jobs rarely wait more than a few days for specialty product. See our brands for the full line card.

FAQs About Insulation Company in Bloomington
Most Bloomington estimates are scheduled within two to three business days. Since our crews work the Fontana basin every week, we can often fit an assessment in earlier when a homeowner calls about a specific problem like a hot second bedroom or visible settling. Call (866) 858-4033 to check our current Bloomington schedule.
Most retrofit insulation jobs – attic top-ups, blown in work, and batt replacement – do not require a permit in San Bernardino County. Some larger projects, like converting an attic to conditioned space with closed-cell spray foam, may trigger permit requirements. We handle the paperwork when needed and will tell you upfront if your job requires it.
Air sealing gets skipped. A homeowner pays for new attic insulation, but the top plates and penetrations are still open, so hot, dusty air pours in and the new material underperforms. In Bloomington’s climate, sealing before blowing is the difference between a fix that lasts and one that disappoints by August. We seal on every blown in and spray foam job we do.
