Insulation Company in Redlands, CA
Most insulation work in Redlands comes down to one problem: heat pouring through the ceiling. We specialize in blown in insulation because it’s the fastest, most complete way to bring an older Redlands attic up to modern thermal performance without tearing the house apart. Homes in the 92373 core were often built before insulation was standard, and even the 1960s and 70s tract houses in 92374 have settled batts that barely slow a 150-degree attic down. If your upstairs rooms cook all summer, call Birch Insulation at (866) 511-7592 and we’ll tell you exactly what’s going on in your attic.
Why Redlands Homes Are Different
Redlands sits in the hot, dry Inland Empire east of Los Angeles, where summer design temperatures regularly pass 100°F and attics can exceed 150°F. That means cooling loads drive insulation decisions here far more than heating ever will. The primary enemy is attic radiant heat and solar gain, which is why the ceiling plane matters so much more than walls or floors in almost every home we inspect across 92373, 92374, and 92375.
The housing stock complicates things. Downtown and the older core of 92373 are full of early-1900s Craftsman and Spanish Colonial Revival homes, many with original knob-and-tube wiring still running through the attic. Before any blown in or batt work goes in, that wiring has to be identified, cleared away from insulation contact, or re-routed. Plaster walls and minimal venting are common too. In 92374, the mid-century and 1960s-70s tract homes usually have some insulation, but it’s often thin, compressed, or settled into uselessness. Newer exurban builds on the city’s edges tend to have other issues: air leaks around can lights, poorly sealed top plates, and undersized attic access hatches that let conditioned air escape all year.
There’s also the fire reality. Redlands gets Santa Ana wind events and occasional wildfire smoke. That makes air-sealing and fire-resistant detailing more than a nice-to-have. We see it as part of doing the job correctly here, not an upgrade.
Our Main Redlands Services
Most Redlands homeowners call us about two things: bringing an under-insulated attic up to code-plus performance, or sealing the entire attic with spray foam to stop heat and air leaks in one pass.
Attic Insulation in Redlands
Attic work in Redlands starts with an honest look at what’s already up there. In older 92373 homes, that often means original uninsulated attics or thin, settled batts over knob-and-tube wiring. In 1960s-70s tract homes, we typically find R-11 or R-19 fiberglass that’s compressed and dirty. The fix depends on the attic’s condition, but most Redlands attics benefit from air-sealing first, then adding blown in fiberglass or cellulose to reach R-38 or better. Radiant barrier work also makes a real difference here because of how hot the roof deck gets. Attic Insulation in Redlands

Spray Foam Insulation in Redlands
Spray foam makes sense in Redlands attics where venting is poor, ducts run through the space, or the homeowner wants to condition the attic itself. Closed-cell foam adds structural strength and moisture control, which helps in older homes with plaster ceilings. Open-cell foam is more cost-effective for sealing the roofline and quieting the house. Both applications stop the radiant heat path that drives up cooling bills here, and both require an experienced installer to get right. Spray Foam Insulation in Redlands

Blown In Insulation in Redlands

In a city where attic temperatures hit 150°F in July, blown in insulation is usually the most practical way to get an older Redlands home up to modern thermal performance. Homes in 92373 and 92374 were often built with thin or no attic insulation, and blown in fiberglass or cellulose can be installed directly over settled batts to bring the ceiling to R-38 or R-49 without a full tear-out. We carry both Blown In Insulation materials and match the product to the attic, not the other way around.
Cellulose Insulation
Signs you need it
Your cooling bills stay high even after the AC runs constantly, and walking upstairs in summer feels like stepping into a wall of heat.
What it costs in Redlands
Cellulose insulation in Redlands typically runs $0.90 – $1.70 per square foot installed, depending on depth and attic access.
How we do it
We air-seal the attic floor first, then dense-pack or loose-fill GreenFiber cellulose to the target R-value, keeping it clear of any old wiring.
Blown In Attic Insulation
Signs you need it
The attic floor has bare spots, or the existing batts are thin, compressed, and coated in dust from years of air movement.
What it costs in Redlands
Blown in attic insulation in Redlands typically costs $0.90 – $2.30 per square foot, with most attics landing between $1,500 and $3,200 all-in.
How we do it
We seal the top plates and penetrations, install baffles where needed, then blow fiberglass or cellulose to an even R-38 or R-49 across the entire attic floor.
Blown In Fiberglass Insulation
Signs you need it
The existing insulation is fluffy and looks thick, but the upstairs rooms still heat up fast because the material has settled below the joists.
What it costs in Redlands
Blown in fiberglass insulation in Redlands typically runs $0.90 – $1.90 per square foot installed, including air-sealing in most attics.
How we do it
We blow Owens Corning fiberglass to a consistent depth across the attic floor, checking depth markers as we go so the R-value is uniform from edge to edge.
Loose Fill Insulation
Signs you need it
Your attic has odd geometry, low clearances, or hard-to-reach corners that batts can’t cover without gaps and compression.
What it costs in Redlands
Loose fill insulation in Redlands typically costs $0.90 – $2.30 per square foot depending on material choice and attic size.
How we do it
We loose-fill the entire attic floor with either fiberglass or cellulose, working around ducts, framing, and electrical according to code clearances.
What Blown In Insulation Costs in Redlands
| Item | Typical range in Redlands |
|---|---|
| Cellulose insulation | $0.90 – $1.70 per sq ft |
| Blown in fiberglass insulation | $0.90 – $1.90 per sq ft |
| Blown in attic insulation (full job) | $1,500 – $3,200 |
Is blown in insulation enough for Redlands summers?
Yes, if the attic floor is air-sealed first and the material reaches R-38 to R-49. Blown in fiberglass or cellulose stops the radiant heat path that drives most cooling costs in Redlands.
Can you blow insulation over old knob-and-tube wiring?
No. Knob-and-tube wiring must be cleared or re-routed before any insulation goes in around it. We inspect for it in every older 92373 attic before work begins. Call (866) 511-7592 for an assessment.

What Redlands Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Katie Whitaker"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Amit Shah"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."
— Neil Hayes
