Insulation Company in Inglewood, CA
Blown in insulation solves a problem Inglewood homeowners know well: rooms that never hold temperature and walls that let every plane passing overhead into the living space. Comfort Zone Insulation Co has served Inglewood since 2012, installing blown-in fiberglass and cellulose in the 1920s stucco bungalows, 1950s wood-frame homes, and 1960s apartment complexes that define this city’s housing stock. Call (855) 341-7856 when you’re ready to stop hearing the 405 and start feeling the temperature you set.
Why Inglewood Homes Are Different
Inglewood’s housing rolls back to the 1920s through the 1950s: wood-frame bungalows and Spanish-style stucco homes in 90301 and 90302 that were built before wall insulation was standard. Many of these walls are empty. Some still have original knob-and-tube wiring, which changes how we approach any cavity work. A blown-in job in those homes isn’t just about R-value. It’s about safely isolating old wiring before dense-packing cellulose around it, and doing it in a way that doesn’t create a fire hazard the original builders never planned for.
The 1960s and 1970s apartment and condo stock around 90303 through 90305 brings a different set of conditions. Shared walls, flat roofs, and minimal sound isolation mean heat and noise transfer between units is constant. We see requests driven by neighbors’ air conditioners almost as often as by the homeowner’s own comfort.
Then there’s the location reality. Homes under the LAX approach and the 405 flight corridors deal with aircraft noise that no amount of single-pane glazing will fix. Inglewood’s mild coastal climate means extreme temperatures are rare. The bigger driver here is air sealing and sound control. What works in Torrance isn’t necessarily the right prescription in Inglewood, because the noise profile and the age of the housing stock are different animals.
Our Main Inglewood Services
Most Inglewood calls fall into two categories: attics that are bleeding conditioned air, and walls or rim joists that need the air-sealing power of spray foam. Here’s what each looks like in this city.
Attic Insulation in Inglewood
Attics in Inglewood’s older homes are often the single biggest comfort leak. Original insulation from the 1950s, if it exists at all, has settled to a fraction of its original depth, and attic bypasses around chimneys, plumbing chases, and recessed lights quietly move air between the living space and outdoors. We treat the attic as a system: air-seal the bypasses first, then bring the insulation depth up to what the space actually needs. In homes near the flight paths, we often pair attic work with wall treatments to cut the noise coming through the roof plane. Learn more about Attic Insulation in Inglewood.

Spray Foam Insulation in Inglewood
Spray foam earns its keep in Inglewood when air sealing matters as much as thermal resistance. Closed-cell foam in a 1950s rim joist stops the stack effect that pulls outside air through the floor. In the 1960s condo buildings with shared walls, open-cell foam inside party walls cuts both heat transfer and the neighbor’s television. Because we install Icynene and Demilec systems rather than a single proprietary line, the foam chemistry matches the specific cavity, not the other way around.

Blown In Insulation in Inglewood
Blown in insulation is the workhorse retrofit for Inglewood’s older housing stock. Most 1920s-to-1950s homes in 90301 and 90302 have empty or underfilled wall cavities, and blown-in fiberglass or cellulose is the practical way to fill them without tearing out plaster or drywall. We pair blown-in work with the local reality: homes under the LAX flight path and the 405 often get dense-packed cellulose in street-facing walls because it measurably reduces aircraft noise while adding real thermal resistance. For a deeper look at the method itself, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Rooms that swing several degrees between morning and afternoon, or walls that feel warm on the inside during a heat wave, usually mean empty or settled cavities in Inglewood’s older frame homes.
What it costs in Inglewood
Blown-in cellulose in Inglewood typically runs $1.50 to $3.50 per square foot installed, depending on cavity depth and whether we’re working around existing wiring.
How we do it
We core holes in the wall cavity, dense-pack GreenFiber cellulose to the correct density, then patch and texture the holes to match the original surface.
Blown In Attic Insulation
Signs you need it
If your attic has less than 6 inches of loose insulation or you can see the ceiling joists clearly from the hatch, you’re losing conditioned air through the roof plane.
What it costs in Inglewood
Blown-in attic insulation in Inglewood typically costs $1.00 to $2.50 per square foot, with the final figure tied to target R-value and whether we’re topping up existing material or starting fresh.
How we do it
We air-seal the bypasses first, then blow loose-fill fiberglass or cellulose to an even depth across the whole attic floor, keeping the soffit vents clear so the roof can breathe.
What Blown In Insulation Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Blown-in cellulose (wall cavities) | $1.50 – $3.50 per sq ft |
| Blown-in attic insulation | $1.00 – $2.50 per sq ft |
| Dense-pack retrofit (existing walls) | $2.00 – $4.00 per sq ft |
Two things push blown-in pricing up in Inglewood: dealing with knob-and-tube wiring that requires isolation before we can dense-pack, and working in apartments with shared walls where we need to coordinate access carefully. We give you a fixed quote before we start, and we don’t add surprise line items after the fact.
Does blown in insulation actually reduce aircraft noise in Inglewood?
Yes. Dense-packed cellulose in street-facing and roof-facing cavities measurably dampens sound transmission, which is why it’s a common request in homes under the LAX and 405 flight paths. It’s not a substitute for acoustic panels, but it makes a real difference in perceived noise. Call (855) 341-7856 to talk through your specific wall assembly.
Can you blow insulation into walls that still have knob-and-tube wiring?
Only after the wiring is properly isolated. We won’t dense-pack cellulose around live knob-and-tube because the combination creates a fire risk. In homes where the wiring is still active, we coordinate with an electrician or adjust the scope before any insulation goes in. Call (855) 341-7856 if you suspect you have original wiring in your walls.
Brands We Service in Inglewood
We install Owens Corning, Johns Manville, Knauf, and Rockwool products, and we keep the common blown-in and batt materials stocked for fast Inglewood turnaround. Rockwool’s mineral wool gets specified often here for its fire resistance and sound attenuation on shared walls. See our brands for the full list of what we carry.

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."
— Dustin Sullivan"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Marco Morales"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
