Insulation Company in Compton, CA
Blown in insulation is the most practical retrofit for Compton’s 1940s and 1950s tract homes, where original attic insulation is usually compacted to half its rated R-value or missing entirely. Creekside Insulation Co has served Compton since 2016, and we carry eight insulation brands so the recommendation matches the house, not our inventory. Cooling drives energy use here, so the work usually means air-sealing first, then blowing in cellulose or fiberglass to block summer heat gain. Call (844) 948-3251 for a free estimate.
Why Compton Homes Are Different
Compton’s housing stock was built fast after WWII, and it shows in the attics. Most of the single-story stucco homes and duplexes we work in across 90220, 90221, 90222, and 90224 went up between 1945 and 1965, with low-pitch vented attics and whatever insulation the builder could get cheap that week. Sixty years later that material has settled, been trampled by storage boxes, or been pulled apart by HVAC crews running ductwork. The marine layer keeps summers mild compared to the Valley, but from June through October the sun still turns those dark composition shingle roofs into heat radiators, and without a proper attic blanket that heat pours straight into bedrooms and living rooms. Compton also has more garage conversions and unpermitted room additions than almost anywhere we work. Those rooms rarely have any insulation at all, and the attic access often got sealed over during the conversion. We find knob-and-tube wiring in maybe one attic in ten, which changes how we plan the job – cellulose and fiberglass settle against old wiring differently, so the approach has to account for it. The short version: Compton insulation work is retrofitting, air-sealing, and correcting sixty years of shortcuts, not just adding R-value on top of a clean new build.
Our Main Compton Services
Most Compton homeowners call us for two reasons: their attic is baking the house all summer, or they have rooms that never hold temperature because the walls and ceiling were never properly insulated. Here are the two services that cover those problems.
Attic Insulation in Compton
An attic in a Compton tract home is usually where half the cooling budget disappears. The original insulation is typically compacted to R-11 or less, the attic floor has gaps around every ceiling fixture, and nobody air-sealed anything when the house was built. We remove or top up the old material, seal penetrations, and install a fresh layer matched to the home’s sun exposure and roof pitch. For low-pitch vented attics, that often means blown-in fiberglass or cellulose; for homes with HVAC equipment up top, we build proper dams and keep airflow clear. Read more on our Attic Insulation in Compton page.

Spray Foam Insulation in Compton
Garage conversions and unpermitted additions are common across Compton, and they are almost never insulated. Open-cell spray foam is often the only practical way to insulate a converted garage without tearing out drywall, because it can be injected into closed cavities and expands to fill odd framing. Closed-cell foam, through Icynene or Demilec, handles the other local problem: flat or low-slope additions where heat builds against the roof deck and ventilation is already compromised. Spray foam also doubles as an air seal, which matters when the original building envelope has more gaps than sealed seams. Details on our Spray Foam Insulation in Compton page.

Blown In Insulation in Compton
Blown in insulation is the go-to retrofit for Compton’s 1940s and 1950s homes because it gets into every odd corner of an old attic without tearing anything apart. In a city where original insulation has settled to nothing and attic floors are full of gaps, loose-fill material covers the whole surface evenly and stops heat at the hottest point of the house. Our crews use GreenFiber cellulose or Johns Manville and Knauf fiberglass. For a deeper look at the options, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation looks like a thin gray blanket from 1962, your upstairs rooms run 8 to 12 degrees hotter than the rest of the house in summer, or you can see bare drywall between the joists.
What it costs in Compton
Blown-in cellulose in a Compton attic typically runs $1.10 to $1.80 per square foot installed, including air-sealing and removal of compromised material.
How we do it
We air-seal all penetrations, dam around any recessed lights or flues, then blow GreenFiber cellulose to the target depth with a calibrated machine and level it across the attic floor.
Blown In Attic Insulation
Signs you need it
Your energy bill climbs every summer even though the thermostat stays put, and the second you open the attic hatch in August the heat hits you like an oven door opening.
What it costs in Compton
A full blown-in attic insulation job in Compton, including removal of old compacted material, air-sealing, and new loose-fill to R-38, usually falls between $1,800 and $3,600 depending on square footage and access.
How we do it
We inspect the attic floor for penetrations and old wiring, seal every gap with foam or caulk, install baffles at the soffits, then blow the insulation to an even depth across the entire attic.
What Blown In Insulation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Cellulose attic insulation (per sq ft) | $1.10 – $1.80 |
| Full attic blow-in, including removal and air-sealing | $1,800 – $3,600 |
| Blown-in insulation for garage conversion or addition | $900 – $2,400 |
How long does blown in insulation last in Compton’s climate?
Cellulose and fiberglass both hold up well here, though Compton’s marine layer means we check for moisture in the attic before blowing anything in. Properly installed loose-fill stays effective for 20 to 30 years. Call (844) 948-3251 for an attic inspection.
Can you blow insulation into walls without removing drywall?
Yes, if the wall cavities are accessible from the attic or exterior. We drill small access holes, blow the material in, and patch them cleanly. In older Compton homes with fire blocking, a wall inspection tells us if dense-packing will work before we start.
Brands We Service in Compton
We install and service GreenFiber cellulose, Owens Corning, Johns Manville, and Knauf fiberglass across every Compton zip code. Parts and materials are stocked locally in our Midway City shop, so most projects start within days, not weeks. See our brands for the full line.

Most insulation retrofit work in Compton does not require a city permit, though if your project involves a garage conversion or addition, the original construction may need to be brought up to code first.

What Compton Customers Say
"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Ernesto Torres"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."
— Vivian Lin"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."
— Craig Kowalski
