Insulation Company in Glen Avon, CA
Blown in insulation is the most common retrofit we handle in Glen Avon, and for good reason: much of the housing stock dates to the 1950s through 1970s, when attic insulation was either absent or a thin layer of fiberglass that has long since settled. Summer temperatures above 100°F turn these attics into ovens that radiate heat into living space all night. We fix that by air-sealing the attic floor and blowing insulation to a depth that actually holds up against Riverside County heat. Call Fontana Insulation at (866) 271-1602 for a free estimate.
Why Glen Avon Homes Are Different
Glen Avon sits in the Jurupa Valley area of Riverside County, where summer heat routinely exceeds 100°F and many homes were built before modern energy codes existed. The attics in these ranch-style and tract homes from the 1950s through 1970s often have R-11 fiberglass batts at best, and just as often nothing but exposed ceiling joists. When outside air hits 105°F, an uninsulated attic can reach 150°F or more. That heat does not stay in the attic. It presses down through the ceiling all afternoon and evening, so the air conditioner runs constantly and the bedrooms still feel warm at midnight.
We also see another pattern in the older tracts near the 60 Freeway: minimal air sealing. Original construction left gaps around plumbing penetrations, recessed light fixtures, and top plates that let conditioned air escape into the attic. Adding insulation without sealing those bypasses is like filling a bucket with a hole in the bottom. In Glen Avon, a proper retrofit almost always starts with sealing before blowing.
The semi-arid climate matters too. Winters are mild, so the primary job is keeping heat out rather than trapping it in. That shifts the material conversation toward reflective barriers, ventilation, and dense-packed blown material that resists heat transfer. Homes with single-pane windows and uninsulated walls lose less heat in winter than you might expect, but they gain heat aggressively in summer through the ceiling. That is why attic work delivers the most noticeable comfort improvement here.
Our Main Glen Avon Services
Most Glen Avon homeowners call us for one of two things: attic insulation retrofits or spray foam for hard-to-reach areas and air sealing. Both are handled in-house by the same crew.
Attic Insulation in Glen Avon
Attic retrofits in Glen Avon usually involve removing old, settled fiberglass, sealing the attic floor, installing baffles to keep soffit vents clear, and blowing new material to the target R-value for our climate zone. We often find original insulation compressed to a fraction of its rated depth, especially in homes along the 60 Freeway corridor. See Attic Insulation in Glen Avon for the full breakdown of materials, costs, and what to expect.
Spray Foam Insulation in Glen Avon
Spray foam earns its keep in Glen Avon on cathedral ceilings, bonus rooms, and band joists where batts and blown material leave gaps. Closed-cell foam also acts as an air barrier, which matters in older homes where air leaks are the bigger energy problem. We install Icynene and Demilec open- and closed-cell systems. For details on where foam makes sense in Glen Avon homes, see Spray Foam Insulation in Glen Avon.

Blown In Insulation in Glen Avon
Blown in insulation is the workhorse retrofit for Glen Avon attics. Most homes here from the 1950s through 1970s have thin, settled fiberglass or bare ceiling joists, and summer attic temperatures above 150°F make the ceiling the single biggest source of indoor heat gain. Blowing loose fill over a sealed attic floor is the fastest, least disruptive way to correct that, and it usually takes one day. This is the core of what we do. For more on methods and materials across the region, see Blown In Insulation.
Cellulose Insulation
Signs you need it
You can see the ceiling joists in your attic, or your existing insulation is paper-thin, dark with dust, and level with or below the joist tops.
What it costs in Glen Avon
Blown-in cellulose in a typical Glen Avon attic runs $1.50 to $3.00 per square foot installed, depending on depth and access.
How we do it
We air-seal the attic floor, install baffles at the eaves, and blow GreenFiber cellulose to the specified depth using a calibrated machine so density is consistent wall to wall.
Blown In Attic Insulation
Signs you need it
Upstairs rooms run 10-15 degrees hotter than downstairs in summer, or your AC runs nonstop on hot afternoons and the house still does not hold temperature.
What it costs in Glen Avon
A full blown-in attic retrofit in Glen Avon typically ranges from $1,500 to $3,200 for a 1,000-1,500 square foot attic, including air sealing.

We remove any compromised old material, seal penetrations, mark final depth, and blow Knauf or CertainTeed fiberglass or GreenFiber cellulose to the R-value target agreed on before work starts.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old batts that are torn, compressed, or shoved to the side, leaving bare drywall visible across large sections.

Blown-in fiberglass in Glen Avon attics falls between $1.00 and $2.50 per square foot installed, with depth calibrated to our climate zone.
How we do it
We prep the attic floor, seal bypasses, confirm ventilation, then blow Knauf or CertainTeed fiberglass to an even depth across the entire attic.
Loose Fill Insulation
Signs you need it
You have an attic with tight access, low clearance, or awkward framing where rolling out batts is not practical.
What it costs in Glen Avon
Loose fill blown in Glen Avon homes runs $1.25 to $2.75 per square foot including prep, material, and cleanup.
How we do it
We run a hose from the truck to the attic, blow loose fill into every corner, and level it to the target depth for uniform coverage.
What Blown In Insulation Costs in Glen Avon
| Item | Typical range in Glen Avon |
|---|---|
| Blown-in attic insulation (full retrofit, incl. air sealing) | $1,500 – $3,200 |
| Blown-in cellulose | $1.50 – $3.00 per sq ft |
| Blown-in fiberglass | $1.00 – $2.50 per sq ft |
Attics with very low clearance, difficult access, or extensive air sealing needs will trend toward the higher end. We give a fixed price before work starts, so the number on the proposal is the number you pay.
How long does blown in insulation last in Glen Avon heat?
Cellulose and fiberglass both hold up well in our climate, but extreme attic heat can settle some materials over 15-20 years. We check depth on every job and top off low spots before blowing new material. Call (866) 271-1602 if your attic needs a depth check.
Can you blow insulation over old fiberglass in my Glen Avon attic?
Sometimes, but only after we inspect. If the old material is dry, not compressed, and free of rodent damage, we can blow new fill right over it. If it is damp or packed down, removal comes first. Call (866) 271-1602 and we will tell you which applies.
Brands We Service in Glen Avon
We install and stand behind Knauf and CertainTeed fiberglass, Rockwool mineral wool, and Icynene spray foam in Glen Avon homes. Because we stock competing brands across price tiers, the recommendation is driven by your attic, your walls, and your budget, not by what we happen to have on the truck.

What Glen Avon Customers Say
"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."
— Sarah Fletcher"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."
— Holly Mercer"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Nadia Aziz
