Insulation Company in Compton, CA
Blown in insulation is the retrofit workhorse for Compton’s 1940s and 1950s stucco tract homes, most of which were built with zero or minimal insulation in the attic. We see R-11 or less up there on a regular basis, with compacted batt remnants that quit doing their job decades ago. The fix is usually blown-in cellulose or fiberglass brought up to R-38 or better, plus targeted air sealing, because Compton’s inland heat means your attic hits 140°F by July and that heat pours straight into the living space. Hollywood Insulation Co has served Compton since 2018. Call (866) 605-6949 for a free estimate.
Why Compton Homes Are Different
Compton’s housing stock is overwhelmingly single-story stucco on raised foundations, built between the 1940s and 1960s. These houses are a specific animal. The walls are stucco over wood frame, so you cannot open up the exterior without a major reconstruction project. That reality makes injection foam and blown-in retrofits the practical path for wall work, because everything has to go in through small access points rather than open cavities. Many of these homes still carry original knob-and-tube wiring and plaster interiors, which means any drill-and-fill approach has to be surgical about where it penetrates.
The attics are the real story. Low-pitch, gable-vented, and baked by Compton’s position on the warmer inland edge of the LA Basin. Cooling loads dominate here, not heating. In August, an under-insulated attic in a Compton home can sit at 140°F, and if your ductwork runs through that space, you are paying to cool air that gets reheated before it ever reaches a register. Santa Ana wind events spike the thermal stress even further. The standard Compton retrofit we see delivers the biggest return in the attic first, walls second, because that is where the physics points.
Our Main Compton Services
Most Compton homeowners call us about two things: getting their attic insulation rebuilt to modern R-value, or air sealing a house that has never had a tight building envelope. Both jobs show up in these 60-plus-year-old stucco homes constantly.
Attic Insulation in Compton
Compton attics from the post-war era are typically shallow, low-pitch, and full of surprises: old knob-and-tube wiring, disconnected vents, compacted fiberglass batt that measures R-11 at best. Our attic work starts with an honest assessment of what is actually up there, then a rebuild to R-38 or higher using the right material for the space. In Compton’s cooling-dominated climate, a radiant barrier and proper ventilation make the difference between an attic that bakes the house and one that stays within a few degrees of outside air.

Spray Foam Insulation in Compton
For Compton homes with raised foundations and stucco exteriors, spray foam does what batt cannot: it air seals and insulates in one pass. Open-cell foam works well in attic roof decks where you want breathability plus a thermal break, while closed-cell brings higher R-value per inch and moisture resistance to rim joists and tight wall cavities. In an older Compton house, foam is often the only way to hit modern performance without tearing open stucco. See Spray Foam Insulation in Compton for the full breakdown.

Blown In Insulation in Compton
Blown in insulation in Compton is the fastest, least invasive way to bring a 60-year-old attic up to modern code without tearing anything apart. We pump loose-fill material through a hose into the attic or wall cavity, where it settles into gaps and covers everything with a continuous thermal layer. In Compton’s tract houses, where access is tight and the stucco exterior cannot be opened, blown-in is usually the right call over batt replacement because it fills irregular cavities completely and leaves no voids. Our Blown In Insulation work spans three manufacturers and both material types: cellulose and fiberglass.
Cellulose Insulation
Signs you need it
Your summer cooling bills keep climbing even though the AC runs fine, or rooms on the sunny side of the house run 8 to 10 degrees warmer than the rest of the floor plan.
What it costs in Compton
Blown-in cellulose for a typical Compton attic runs $1.60 to $2.80 per square foot installed, including removal of the old compacted batt when needed.
How we do it
We map the attic, seal air leaks around top plates and penetrations, then blow GreenFiber cellulose to the specified depth using a two-person crew and calibrated metering.
Blown In Attic Insulation
Signs you need it
You can see the attic floor joists through the existing insulation, or the current layer measures less than 6 inches deep in an era when Compton homes need R-38 minimum.
What it costs in Compton
Attic-only blown-in jobs in Compton typically run $2,200 to $4,800 for a 1,000 to 1,500 square foot home at R-38, with older homes trending to the higher end.
How we do it
We remove or bridge the old material, install vent baffles and a radiant barrier where the roof profile allows, then blow to a measured, consistent depth with chalked depth markers.
What Blown In Insulation Costs in Compton
| Item | Typical range in Compton |
|---|---|
| Cellulose blown-in per sq ft | $1.60 – $2.80 installed |
| Fiberglass blown-in per sq ft | $1.40 – $2.50 installed |
| Attic R-38 retrofit (1,000 – 1,500 sq ft home) | $2,200 – $4,800 |
Is blown in insulation worth it in Compton?
Yes. Compton attics regularly hit 140°F in summer, and blown-in at R-38 cuts heat transfer into the house dramatically, so cooling loads drop and rooms stay more even throughout the day.
Can you add blown in insulation over old batt?
Sometimes, yes. If the old batt is dry and uncompacted we can blow over it. If it is dusted, rodent-damaged, or compressed to nothing, we remove it first so the new material performs as specified.
Brands We Service in Compton
We install blown-in products from CertainTeed and GreenFiber, plus spray foam systems from Icynene and Demilec. Fiberglass batt from Owens Corning and Johns Manville rounds out the attic line. See our brands for the full manufacturer list and what we stock locally for Compton jobs.

Most attic and wall retrofit insulation work in Compton does not require a permit, since it is non-structural. If a job does trigger a review, we handle the paperwork. We always check current city requirements before we start so you are not caught off guard.
For the attic, blown-in cellulose or fiberglass to R-38 is the standard fix in Compton. For walls, injection or drill-and-fill foam is the only practical route since the stucco exterior cannot be opened up. The right answer depends on what is already up there, which we assess free of charge.

What Compton Customers Say
"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."
— Miguel Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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."
— Cole Sullivan
