Insulation Company in San Bernardino, CA
Blown in insulation is the most common retrofit we install in San Bernardino, where single-story tract homes and mid-century bungalows sit under 150°F attics all summer. The older wood-frame houses in 92410 and 92411 rarely have more than R-11 up there, and decades of Santa Ana dust plus rodent traffic have usually crushed what little exists. We’re Orange County Insulation, an insulation-only contractor, and we’ve served San Bernardino since 2013. Call (877) 680-3557 when you’re ready to stop paying for cooled air that slips straight through your ceiling.
Why San Bernardino Homes Are Different
San Bernardino sits in the Inland Empire’s heat bowl. Summer highs routinely blast past 100°F, and the Santa Ana winds strip away whatever buffer your attic might have held. That means attic temperatures spike to 150°F or more, and heat pours down through your ceiling faster than your AC can fight it. This is not the mild coastal retrofit logic that dominates Orange County or LA. Here, the insulation priority is cooling-season performance: keeping the heat out, not the warmth in.
The housing stock compounds the problem. Most of San Bernardino is post-WWII single-story tract homes with low-pitch or flat roofs and vented attics that bake under the inland sun. In the older central and east-side neighborhoods like 92404, 92410, and 92411, we routinely find original rock wool or thin fiberglass batts that have sagged, been crushed by decades of foot traffic, or been chewed through by rodents. Flex-duct runs baking in those attics leak conditioned air straight outside. An “insulation upgrade” here is often really a rodent-damage and duct-sealing repair job before any new R-value goes in.
Our Main San Bernardino Services
The two jobs San Bernardino homeowners call us about most are attic insulation and spray foam, and each has its own dedicated San Bernardino page linked below.
Attic Insulation in San Bernardino
Attic work is the single highest-ROI trade in this city. When your attic is 150°F and your living room is 78°F, the insulation between them is the only thing standing between you and a $400 August electric bill. In homes across 92408 and 92410, we pull out old, settled material, seal the ductwork and top plates, and install fresh insulation matched to the roof pitch and venting. Most San Bernardino attics we see were built for a different climate and a different energy price. The fix is specific, not generic. Attic Insulation in San Bernardino covers exactly what we do up there.
Spray Foam Insulation in San Bernardino
For San Bernardino homes with low-pitch roofs, cathedral ceilings, or bonus rooms that never cool down, spray foam changes the equation. Closed-cell foam air-seals and insulates in one pass, which matters when Santa Ana dust pushes through every gap in a vented attic. We install both open-cell and closed-cell systems using Icynene and Demilec products, so we’re not steering you toward the one foam we happen to stock. Spray Foam Insulation in San Bernardino explains when each makes sense here.

Blown In Insulation in San Bernardino
Blown in insulation is the most practical retrofit for the vast majority of San Bernardino homes, because it fills irregular attic cavities fast and hits the R-values that make a real difference against 100°F-plus summers. Most houses here have vented attics with original or under-insulated material, and blown-in cellulose or fiberglass lets us cover the entire attic floor evenly, including the spots batts never reach. We install Blown In Insulation as a standalone service, which means every crew member on the job is there for one reason only: getting the attic right.
Cellulose Insulation
Signs you need it
Your attic insulation looks like old, gray, settled newspaper or rock wool, and your upstairs rooms heat up within an hour of the AC cycling off in summer.
What it costs in San Bernardino
Blown-in cellulose for a typical San Bernardino attic runs $1.10 to $2.40 per square foot, depending on the target R-value and how much old material we need to remove first.
How we do it
We remove damaged or rodent-soiled material, air-seal the top plates and penetrations, and blow cellulose from GreenFiber to the specified depth, typically R-38 to R-60.
Blown In Attic Insulation
Signs you need it
Your attic has thin, patchy coverage, usually R-11 or less, and the ceiling feels warm to the touch by mid-afternoon.
What it costs in San Bernardino
Blown-in fiberglass attic insulation in San Bernardino runs $1.00 to $2.20 per square foot, with the final figure depending on depth, access, and whether the attic needs rodent cleanup first.
How we do it
We seal the attic floor penetrations, mark target depth, and blow loose-fill fiberglass from Owens Corning or Johns Manville evenly across the entire attic floor.
Blown In Fiberglass Insulation
Signs you need it
You see bare drywall or wooden joists between thin, dusty pink or yellow batts, and the insulation shifts when you touch it.
What it costs in San Bernardino
Blown-in fiberglass for a typical San Bernardino attic runs $1.00 to $2.20 per square foot, including removal of the old smashed batts and new blown-in coverage.
How we do it
We vacuum out the degraded material, seal the attic floor, and blow fiberglass from Knauf or Johns Manville to the depth that hits your target R-value.
Loose Fill Insulation
Signs you need it
The existing insulation is uneven, settled into the joist bays, or completely missing in corners and around roof penetrations.
What it costs in San Bernardino
Loose fill insulation retrofits in San Bernardino run $1.00 to $2.40 per square foot, depending on whether we’re topping off existing material or starting from a bare attic.
How we do it
We level the attic floor, air-seal gaps, and blow cellulose or fiberglass in a consistent layer so every square foot gets the same thermal resistance.

Is blown in insulation worth it in San Bernardino’s heat?
Yes, and it’s usually the best dollar-for-dollar fix in this city. San Bernardino attics hit 150°F, and blown-in coverage at R-38 or higher cuts the heat transfer into your living space dramatically. The first August bill usually shows it. Call (877) 680-3557 for a free estimate.
How long does blown in insulation last in San Bernardino?
Cellulose and fiberglass both last 20 to 30 years if the attic stays dry and rodent-free. In San Bernardino, the bigger issue is decades of settling and dust; once we top it off or replace it, you’re set. Call (877) 680-3557 to schedule an attic check.
