Insulation Company in Redlands, CA
Blown in insulation is the most common fix we recommend for Redlands homes, and for good reason: a large share of the housing stock near downtown was built before modern energy codes existed. These Craftsman and Spanish Revival bungalows in 92373 often have shallow attic cavities or legacy material that has settled into a thin, ineffective layer. When summer temperatures push past 100°F, that under-insulated attic turns the whole house into an oven. North Tustin Insulation has served Redlands since 2011 with blown-in fiberglass and cellulose retrofits matched to each home’s ceiling framing and venting. Call (877) 265-5712 for a free estimate.
Why Redlands Homes Are Different
Redlands sits in the inland Inland Empire east of Los Angeles, where the climate punishes attics all summer. Long stretches of 100°F+ days heat attic air to 140°F or more, and that heat radiates down through ceilings for hours after sunset. Homes in the 92374 growth areas – mostly 1950s through 1970s ranch tract builds – were insulated to standards that looked fine in 1965 and look terrible today. Many have three or four inches of original fiberglass batts in the attic, sometimes less. The older citrus-belt blocks around downtown are different again: original vented attics under clay-tile Spanish roofs, low-clearance access, and wall cavities that date to the knob-and-tube era. Blown in insulation works well in both conditions because it fills irregular cavities and settles around obstructions, but the tile roofs and low attics require careful access planning and vent placement that tract-home work elsewhere doesn’t. The mature tree canopy is beautiful and also drops debris into attic vents, which is worth inspecting when we assess airflow.
Our Main Redlands Services
Redlands homeowners call us most often about two things: fixing or upgrading attic insulation, and sealing the building envelope with spray foam. Both are covered below.
Attic Insulation in Redlands
Attic insulation makes the biggest difference in Redlands because heat gain through the roof is the dominant cooling load here. We inspect existing material, measure depth across the attic floor, check vent baffles, and then blow in new fiberglass or cellulose to the R-value the home needs. Older bungalows near downtown often need air sealing first, since gaps around ceiling fixtures and top plates let conditioned air escape constantly. Learn more about how we handle these retrofits on our dedicated page: Attic Insulation in Redlands.
Spray Foam Insulation in Redlands
Spray foam earns its keep in Redlands when a homeowner wants air sealing and insulation in one step. Closed-cell foam works well in low-clearance attics under tile roofs, where batt or blown material would compress or block airflow. Open-cell foam suits wall cavities in mid-century ranch homes that need the air sealing benefit without the full rigidity. We install both Icynene and Demilec systems, which means the recommendation follows the home’s framing and ventilation reality, not the other way around. See Spray Foam Insulation in Redlands for the full breakdown.

Blown In Insulation in Redlands
Blown in insulation in Redlands is a retrofit-friendly way to bring an under-insulated attic up to current performance without tearing out ceilings or rebuilding roof framing. The method works especially well in the older 92373 homes with irregular joist spacing and low-clearance attics, because loose material flows around obstructions and fills the cavity completely. Settled or compacted legacy insulation – common in 1950s and 60s ranches across 92374 – can be topped up with fresh blown-in material to restore the full R-value. We carry GreenFiber cellulose and fiberglass from multiple manufacturers, so the material follows the home’s needs. This is our core service, and you can read the full method breakdown on our Blown In Insulation hub page. Here’s what Redlands homeowners ask us to do most often.
Blown In Attic Insulation
Signs you need it
Rooms under the attic feel hot by mid-afternoon even with the AC running, and the upstairs thermostat fights to hold the set temperature.
What it costs in Redlands
Blown in attic insulation in Redlands typically runs $1,800 to $3,800 depending on the attic’s square footage, current depth, and whether we remove settled material first.
How we do it
We seal air leaks at the ceiling plane, install or verify vent baffles at the eaves, then blow loose fiberglass or cellulose to the target depth across the full attic floor.
Loose Fill Insulation
Signs you need it
Your attic has bare spots, thin coverage, or old material that has compacted to an inch or two below the top of the joists.
What it costs in Redlands
Loose fill insulation for a typical Redlands attic costs $1,600 to $3,400, including material, equipment, and cleanup of any existing debris.
How we do it
We remove or level the old material as needed, mark target depth, and use a calibrated blowing machine to distribute loose fill evenly to the specified R-value.
Cellulose Insulation
Signs you need it
You want a recycled-content option with better sound damping and air-blocking performance than standard fiberglass, and your attic has accessible coverage area.
What it costs in Redlands
Cellulose insulation in Redlands typically costs $2,000 to $3,900, with GreenFiber recycled cellulose available as a sustainable choice.
How we do it
We install GreenFiber cellulose with a blowing system that fluffs the material, fills cavities, and creates a dense thermal blanket that resists settling over time.
What Blown In Insulation Costs in Redlands
| Item | Typical range in Redlands |
|---|---|
| Blown in attic insulation | $1,800 – $3,800 |
| Loose fill insulation | $1,600 – $3,400 |
| Cellulose insulation | $2,000 – $3,900 |
Can you blow insulation over existing material in Redlands attics?
Yes, in most Redlands homes we can blow new material directly over existing loose fill or batt insulation, as long as the old material is dry, free of mold, and not heavily settled or compressed. We inspect first and level or remove problem areas before adding new depth.
How much does blown in insulation cut cooling costs in Redlands?
Most Redlands homeowners see a 15 to 25 percent reduction in summer cooling costs after bringing attic insulation from R-11 or less up to R-38 or R-49, depending on the home’s orientation, window area, and AC efficiency. Call (877) 265-5712 for a specific estimate.

What Redlands Customers Say
"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Nathan Padgett"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Gabriela Herrera"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Ryan Rhodes
