Insulation Company in Redlands, CA
Blown in insulation in Redlands is the most common retrofit we install, and it’s typically the right call for the citrus-era homes and 1950s-70s tract houses that dominate this city. Attics here regularly hit 140 to 160 degrees Fahrenheit in summer, which means the job is less about keeping heat in and more about slowing radiant heat from cooking the living spaces below. If your Redlands home has thin, settled, or missing attic insulation, call (866) 393-6041 and we’ll tell you straight whether blown-in fiberglass, cellulose, or a different approach actually fits.
Why Redlands Homes Are Different
Redlands sits on the hot inland side of the Orange Belt, east of where the coastal marine layer burns off, so the attic heat load is punishing. In August, roof deck temperatures routinely push past 140 degrees, and an under-insulated attic turns that heat into higher cooling bills and second-floor rooms that never quite cool down. The insulation strategy here is built around radiant heat control and air sealing, not cold-weather performance.
The housing stock compounds the challenge. The pre-1950 Craftsman, Spanish Colonial Revival, and bungalow homes near downtown and in the 92373 hills were built long before Title 24 insulation standards existed. Many of them have knob-and-tube-era construction, original single-pane double-hung windows, and minimal or zero attic insulation. The 1950s through 1970s single-story tract homes in 92374 and 92375 are better framed but often have settled fiberglass batts that perform at a fraction of their original R-value. In both cases, air leakage through redwood or cedar siding and knee-wall transitions can undo the gains from new insulation unless the sealing happens first. That’s the work we do most often in Redlands.
Our Main Redlands Services
Redlands homeowners call us most often about two specific jobs: attic insulation for older homes that never had enough, and spray foam for attics and rim joists where air sealing matters as much as R-value.
Attic Insulation in Redlands
Older Redlands homes, particularly the pre-1950 citrus-boom houses, often have attic insulation that is thin, compressed, or missing entirely. The fix usually starts with air sealing the top plates and knee-wall transitions, then blowing in fresh material to the right depth for our climate. In Redlands, that depth matters more for summer than winter. For the full rundown on materials, R-values, and what the job looks like in a 1920s Craftsman versus a 1960s tract home, see our Attic Insulation in Redlands page.

Spray Foam Insulation in Redlands
When dust, smoke, and air infiltration are part of the problem, spray foam changes the equation. Redlands gets Santa Ana wind events and wildfire smoke seasons, and open-cell or closed-cell foam can air-seal an attic in ways blown-in material alone cannot. Closed-cell spray foam creates both an air barrier and a thermal barrier in a single application. For homes with unvented attics or HVAC equipment in the attic, this is often the highest-performance option. We install Icynene and Demilec systems, and you can read the specifics on our Spray Foam Insulation in Redlands page.

Blown In Insulation in Redlands
Blown in insulation is the workhorse retrofit for Redlands because it solves the two biggest problems in this housing stock: thin or settled attic insulation and the radiant heat that builds up inside a poorly ventilated attic. In the older citrus-era homes around downtown, the original redwood or cedar siding and single-pane windows leave so much air infiltration that we often have to air-seal and address knee-wall and attic transitions before adding insulation. Otherwise the R-value gain is lost to leakage, and attic temps can still climb past 140 degrees on an August afternoon. Blown-in fiberglass and cellulose both perform well here once the sealing is done, and the material choice comes down to cost, dust sensitivity, and whether you want a recycled-content product. We install blown in insulation using fiberglass from Owens Corning and Johns Manville, and cellulose from GreenFiber. For a deeper look at how the material performs and what to expect, see our Blown In Insulation hub.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the ceiling joists, or you want a dense-packed material with better sound control and a recycled-content story.
What it costs in Redlands
Blown-in cellulose in Redlands typically runs $1.20 to $2.50 per square foot for an attic, with one-story homes on the lower end and dense-pack wall retrofits on the higher end.
How we do it
We air-seal the attic floor penetrations first, then blow GreenFiber cellulose to the depth required for R-38 to R-60, keeping baffles clear at the eaves so attic ventilation still works.
Blown In Attic Insulation
Signs you need it
Upstairs rooms run 10 to 15 degrees hotter than downstairs in summer, or your attic insulation is thin, patchy, or looks compressed and dirty.
What it costs in Redlands
Blown-in attic insulation in Redlands generally falls between $1,500 and $3,500 for a typical 1,000 to 1,500 square foot attic, depending on current R-value and how much air sealing is needed first.
How we do it
We remove or level any failed material, seal top plates and penetrations with foam or caulk, then blow fiberglass or cellulose to a consistent depth with an R-value target sized for Redlands’ cooling-dominated climate.
What Blown In Insulation Costs in Redlands
| Item | Typical range in Redlands |
|---|---|
| Blown-in attic insulation (fiberglass) | $1.20 – $2.80 per sq ft |
| Blown-in cellulose attic insulation | $1.20 – $2.50 per sq ft |
| Dense-pack wall retrofit (cellulose) | $2.50 – $4.00 per sq ft of wall |
Is blown in insulation worth it in Redlands when it rarely gets cold?
Yes. The payoff in Redlands is summer cooling, not winter heat. Attic insulation slows radiant heat moving down into living spaces, which reduces air conditioning run time and helps upstairs rooms stay closer to the thermostat setting.
Can you blow insulation over my existing attic insulation in Redlands?
Usually, yes, as long as the existing material is dry and not infested or full of dust from old roof leaks. We’ll confirm during an attic inspection before quoting.

Older citrus-era homes with knob-and-tube wiring that needs an electrician’s clearance before we work also add cost. We quote upfront and don’t add surprise line items.

FAQs About Insulation Company in Redlands
Most Redlands homes get an inspection within one to three business days. If you have exposed wiring or a leaking roof that needs another trade first, we’ll tell you what to fix before we insulate so you don’t pay twice.
For straightforward attic or wall insulation retrofits, Redlands typically doesn’t require a permit. If the work is part of a larger remodel, an addition, or if spray foam is going into an unvented attic assembly, the city may want a permit. Call (866) 393-6041 and we’ll help you determine what applies to your job.
Yes, but with a safety gate. We don’t blow insulation over live knob-and-tube wiring. We’ll inspect the attic, and if active knob-and-tube is present, we’ll ask you to have a licensed electrician address it before insulation goes in.
