Insulation Company in Redlands, CA
Blown in insulation is the workhorse retrofit for Redlands homes, especially the older Craftsman and Spanish Colonial Revival houses packed around downtown that were built when nobody thought about attic R-value. We spend a lot of time in Redlands attics that have either nothing up there or a thin layer of settled fiberglass from the Nixon administration. The summer heat regularly pushes past 100°F, and without proper attic coverage the air conditioner runs constantly just to keep a ceiling at 78. Call us at (855) 382-3451 and we’ll tell you what’s actually going on above your ceiling.
Thermal Insulation Co has served Redlands since 2012. We’re a dedicated insulation contractor, which means insulation is all we do, and we carry eight material brands plus three installation methods so the recommendation fits the house rather than whatever happens to be on the truck.
Why Redlands Homes Are Different
Redlands sits east of Los Angeles in the Inland Empire, where summer heat regularly exceeds 100°F and the Santa Ana winds strip moisture from the air. Insulation here has to perform as a radiant-heat barrier as much as a thermal blanket. Older Redlands attics often bake because they lack radiant barriers and adequate attic ventilation, even when the insulation itself was installed to inland California standards when the home was built.
The housing stock compounds the problem. Near downtown you find historic Craftsman and Spanish Colonial Revival homes, many with knob-and-tube era attics that have never seen insulation. Move north or east and you hit mid-century ranch tract homes from the 1950s and 60s with thin, settled fiberglass batts that were under-insulated from day one. Newer subdivisions in 92373 and 92374 tend to be better sealed, but even they benefit from attic upgrades because the sun here is relentless from May through October.
The dry climate and seasonal Santa Ana winds matter for material selection. Blown-in fiberglass behaves differently in a 110°F attic than it does in a coastal climate. Cellulose handles the dry air well but needs proper ventilation above it. And in the older neighborhoods around downtown Redlands, original Craftsman bungalows often have attic spaces with minimal ventilation, so a standard blown-in job can trap heat unless the crew adds proper venting and a radiant barrier. We see that pattern on almost every pre-1950 Redlands attic we open.
Our Main Redlands Services
Redlands homeowners call us most about two things: attics that are under-insulated, and spray foam for rooms or additions that fiberglass cannot fix. Here’s what each involves locally.
Attic Insulation in Redlands
Attic insulation is where most Redlands homes lose the most cooling energy. Whether the attic is a 1920s Craftsman attic with nothing in it or a 1960s ranch with flattened fiberglass batts, the fix is usually the same: air seal the attic floor, bring ventilation up to standard, and install insulation matched to the home’s R-value target. The Santa Ana winds dry everything out, so attic work happens year-round without weather delays. For a full breakdown of how we handle attic jobs in Redlands, see Attic Insulation in Redlands.
Spray Foam Insulation in Redlands
Spray foam insulation solves problems blown-in and batt insulation cannot: air sealing, hard-to-reach cavities, and enclosed spaces. In Redlands, we use open-cell foam for interior sound control and closed-cell foam where moisture resistance or higher R-value per inch matters, using Demilec and Icynene systems. Older Redlands homes with unvented attics or converted garage spaces often benefit from foam where loose-fill would underperform. Details on the two foam types and where each makes sense are on Spray Foam Insulation in Redlands.

Blown In Insulation in Redlands
Blown in insulation is the most common retrofit we install in Redlands, because so much of the housing stock was built before modern energy codes and now has either bare attics or a thin layer of settled material that was under-specified from the start. In the older neighborhoods around downtown, we regularly find attics above Craftsman bungalows with nothing but exposed joists and maybe a few batts tossed in decades ago. The hot, dry Inland Empire summer means those attics hit 130°F or more, and that heat radiates down into the living space all afternoon. Blown in insulation, installed to the correct depth over an air-sealed attic floor, cuts that heat transfer dramatically. We carry both fiberglass and cellulose loose-fill so the material choice matches the home’s conditions. For a deeper look at the method and material options, see Blown In Insulation.
Cellulose Insulation
Signs you need it
You want a higher-thermal-mass attic insulation, prefer a recycled-content material, or have an older Redlands attic where the existing insulation has settled below the joist tops.
What it costs in Redlands
Blown-in cellulose in Redlands typically runs $1.15 to $2.00 per square foot, depending on target R-value and prep work like air sealing.
How we do it
We air seal the attic floor, mark target depth, then blow GreenFiber cellulose to the specified R-value using calibrated equipment so the coverage is even.
Blown In Attic Insulation
Signs you need it
Rooms below the attic run hot in Redlands summer afternoons, the AC cycles constantly, or you can see bare joists and settled insulation when you look up there.
What it costs in Redlands
Full attic blow-in jobs in Redlands typically run $1.15 to $2.00 per square foot, with a 1500-square-foot attic falling around $1,725 to $3,000.
How we do it
We seal bypasses and penetrations, install or verify attic ventilation, then blow loose-fill insulation to the R-value the home needs, usually R-38 or higher in Redlands.
Blown In Fiberglass Insulation
Signs you need it
You have an attic with existing fiberglass batts that have settled or flattened, and want to top them up without removing them.
What it costs in Redlands
Blown-in fiberglass in Redlands typically runs $1.20 to $1.90 per square foot, depending on depth and whether we air seal first.
How we do it
We blow loose-fill fiberglass from Owens Corning or Johns Manville over the existing insulation or bare attic floor, using depth markers to hit the target R-value consistently.
What Blown In Insulation Costs in Redlands
| Item | Typical range in Redlands |
|---|---|

Does Redlands weather affect blown in insulation performance?
The dry heat and Santa Ana winds dry out blown-in insulation and keep it lofted if the attic is ventilated, but poor ventilation can trap hot air and make the home hotter. A proper venting check comes standard on every Redlands attic job.
Is blown in insulation worth it in an old Redlands home?
Yes. The pre-1950 homes near downtown Redlands were built with no attic insulation at all, so a blow-in retrofit is often the single highest-impact upgrade for cooling comfort and summer energy use.

What Redlands Customers Say
"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Maya Singh"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Christine Park"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
