Insulation Company in Inglewood, CA
Blown in insulation is the most common call we take from Inglewood homeowners, and for good reason: most of the city’s housing stock predates modern energy codes, leaving walls and attics under-insulated or empty. Homes near Century Boulevard carry an extra burden, with LAX flight path noise pushing sound control up the priority list alongside thermal comfort. Hollywood Insulation Co has served Inglewood since 2018 with blown-in cellulose, fiberglass, and loose fill systems matched to each home’s actual construction.

Why Inglewood Homes Are Different
Inglewood’s residential fabric is dominated by 1940s through 1960s single-story stucco homes and low-rise apartment buildings. Many of these structures were built before wall insulation was standard practice, so the original cavities often sit empty. When insulation does exist, it has usually settled, compressed, or been pulled apart during decades of rewiring, plumbing repairs, or wall fur-outs. The city’s mild coastal climate means heating and cooling loads are moderate, but the intense afternoon sun on west-facing walls and occasional Santa Ana heat spikes can turn an uninsulated attic into an oven that radiates heat into living spaces for hours after sunset.
The flight path complication is real. Homes in the 90307, 90308, 90309, and 90310 ZIP codes that sit under LAX approach routes get persistent aircraft noise, and we field regular requests for wall and ceiling insulation upgrades aimed at dampening that sound. Technicians working near Century Boulevard often find that original 1950s walls have been furred out with extra drywall or soundboard over the decades. Those improvised assemblies conceal hidden conduits and require careful probing before any retrofit begins. We adjust our drilling, filling, and cleanup approach accordingly, protecting the existing sound barrier while adding thermal performance.
Our Main Inglewood Services
Two services account for most of the insulation consultations we book in Inglewood: attic insulation and spray foam. Each addresses a different failure pattern in our local housing stock.
Attic Insulation in Inglewood
Inglewood attics in 1940s through 1960s homes typically hold a thin, matted layer of original batt insulation, often R-11 or less. In summer, that attic layer is the single biggest driver of upstairs heat gain. We inspect the existing assembly, check for ventilation and any knob-and-tube wiring that complicates retrofit work, and then recommend either blown-in fill over the old batts or a full removal and replacement. Air sealing of top plates, light fixtures, and plumbing penetrations is part of the job, not an add-on. Read the full breakdown: Attic Insulation in Inglewood.
Spray Foam Insulation in Inglewood
Spray foam earns its keep in Inglewood where air leakage and sound are the main complaints. Closed-cell foam is particularly useful in the low-rise apartment walls near transit corridors, where sound transmission between units is a persistent issue in older construction. We install both Icynene open-cell and Demilec closed-cell systems, choosing the chemistry based on the cavity depth, moisture exposure, and whether the homeowner is chasing R-value, air sealing, or noise reduction. See the methods and applications in detail: Spray Foam Insulation in Inglewood.

Blown In Insulation in Inglewood
Blown in insulation is our most requested service in Inglewood because it matches the retrofit reality of the city’s older homes. Drilling and filling existing wall cavities, topping up settled attic insulation, and dense-packing open bays account for the majority of our blown-in work. The method works without tearing out plaster or drywall, which matters when homeowners want to preserve original 1950s wall finishes or the soundboard layers that have accumulated over them. We install Blown In Insulation using GreenFiber cellulose or Johns Manville fiberglass, selected for the cavity and the job. Inglewood’s stucco exteriors respond well to the drill-and-fill technique, since patching a small stucco hole is far less disruptive than opening walls from the inside.
Cellulose Insulation
Signs you need it
Rooms that stay hot in summer or cold in winter despite a running HVAC system, or walls that feel hollow and transfer every outdoor sound, usually point to empty or settled cavities in these older Inglewood homes.
What it costs in Inglewood
Blown-in cellulose for attics typically runs $1.00 – $2.50 per square foot, and wall cavity dense-pack usually lands between $1.50 – $3.50 per square foot in Inglewood.
How we do it
We drill small access holes in existing walls or lay a hose into open attic floors, then dense-pack or loose-fill GreenFiber cellulose to the specified depth, patch the holes, and clean up the work area.
Blown In Attic Insulation
Signs you need it
An attic floor with less than 11 inches of existing loose fill, or visible bare spots where old batts have been moved, means R-value has dropped well below what modern code expects for Inglewood’s climate.
What it costs in Inglewood
Blown-in attic insulation typically runs $1.00 – $2.50 per square foot for blown-in fiberglass or cellulose in Inglewood, depending on depth and whether we are topping up or starting clean.
How we do it
We air seal penetrations, mark target depth, blow loose fill evenly across the attic floor with a calibrated hose, and verify final R-value before we leave.
Blown In Fiberglass Insulation
Signs you need it
When blown-in fiberglass is specified, it is usually because the cavity needs a product that will not settle over time and can be removed more easily later if hidden wiring must be accessed.
What it costs in Inglewood
Blown-in fiberglass runs $1.00 – $2.70 per square foot for attic work and starts around $1.50 per square foot for wall applications in Inglewood.
How we do it
We blow Johns Manville fiberglass into open attics or through access holes in walls, using density checks to reach the specified R-value without compressing the material.
What Blown In Insulation Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Blown-in attic insulation (cellulose or fiberglass) | $1.00 – $2.70 per sq ft |
| Wall cavity dense-pack cellulose | $1.50 – $3.50 per sq ft |
| Air sealing before blowing | $0.50 – $1.00 per sq ft |
Two factors push cost higher in Inglewood: the extra care required when walls have been furred out with soundboard and hidden conduits, and the need to work around original knob-and-tube wiring, which requires inspection before any insulation touches those cavities. We quote the full job upfront, no surprise line items on the invoice.
How long does blown in insulation take in Inglewood?
Most attic blow-ins wrap up in four to six hours, while drill-and-fill wall jobs take a full day for a typical single-story Inglewood stucco home. We schedule and finish on time.
Can you match blown in insulation to Inglewood’s older walls?
Yes. We dense-pack GreenFiber cellulose into original 1940s and 1950s wall cavities through small exterior or interior openings, preserving the drywall and any soundboard layers already in place.

Our Inglewood crews install GreenFiber cellulose, Rockwool mineral wool, and Owens Corning fiberglass on a routine basis, and we keep CertainTeed batts and Icynene spray foam systems stocked for the wide mix of housing eras across the city. That brand coverage means we are never forcing one product onto a job it does not fit. See our brands.

What Inglewood 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."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong"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
