Fast, Reliable Spray Foam Insulation Across Inglewood
Spray foam insulation in Inglewood typically runs $2.50 – $6.50 per board foot installed, with most whole-attic or rim-joist jobs landing between $1,800 and $7,200 depending on foam type, depth, and access. We’ve been in and out of homes in the 90301 and 90304 flats under the LAX approach long enough to know that half the reason homeowners call us is noise, not just energy bills. That changes how we spec the foam, how thick we spray it, and where we put it. Brea Insulation is a dedicated insulation contractor, which means spray foam is what we do, not something we tack onto a remodeling bid.

Why Brea Insulation Is Inglewood’s Preferred Spray Foam Insulation Company
Insulation is the only trade on our menu. That’s not a slogan. When you call Brea Insulation for a spray foam job in Inglewood, you get a tech who has spent years working inside attics, rim joists, and crawl spaces, not a generalist squeezing your job between a water-heater swap and a drywall patch.
Phil Darnell built Brea Insulation around a simple idea: carry eight material brands, offer all three installation methods, and match the product to the house rather than the other way around. That means an Inglewood bungalow with open wall cavities gets a different foam spec than a stucco fourplex near the stadium. We stock Owens Corning, Icynene, Demilec, and GreenFiber among others, which gives us room to be honest about what each job actually needs. No split attention across unrelated trades. Just insulation, done by people who know the difference between open-cell and closed-cell foam and when each one earns its cost.
Response time to Inglewood is usually same-week, and we cover 90306, 90307, 90308, and 90309 on a regular basis. We’ve walked enough of those pre-war floor plans to know where the rim joist is hiding and how the roof deck handles August sun.
Rim Joist Spray Foam in Inglewood
Rim joist spray foam in Inglewood is the single highest-impact air-sealing job we do on the 1920s – 1950s bungalows that line the streets between Florence and Manchester. The rim joist is the framed band where your floor system meets the foundation wall, and in older Inglewood homes it’s almost never sealed. That gap pulls marine-layer humidity into the floor cavities and lets whatever air moves under the house find its way into the living space. Closed-cell foam shot into the rim joist seals it and adds structural rigidity, which matters on older framing.
Acoustic Sealing at the Floor Line
On homes under the LAX final approach in 90301 and 90304, the rim joist is also a sound path. Jet noise doesn’t just enter through windows. It moves through the unsealed floor-to-wall transition and up through wall cavities. Sealing the rim with closed-cell foam closes that flanking route before air or low-frequency sound can get through.
What It Costs
A typical rim joist spray foam job in Inglewood runs $900 – $2,800 depending on crawl-space access, linear footage, and whether we’re working around existing wiring or plumbing. It’s usually done in under a day.
Crawl Space Spray Foam Insulation in Inglewood
Crawl space spray foam insulation in Inglewood is a moisture-control job first and an R-value job second. Marine-layer humidity rolls into the 90306 and 90307 ZIP codes most mornings, and unsealed crawl spaces pull that damp air into floor systems all day. Foam applied to the crawl space ceiling seals the floor assembly and stops moist air from condensing on joists and subfloor. Applied to the crawl space walls, it turns the space into a conditioned buffer instead of a wet, drafty void.
Moisture First, Then Foam
We won’t spray over damp wood. If the crawl space has standing water, active leaks, or heavy condensation, we address that first, because closed-cell foam over moisture traps it and rots the framing from the inside out. In Inglewood’s coastal air, this is not a corner to cut.
What It Costs
A crawl space spray foam job in Inglewood generally runs $2,200 – $6,500 for the full perimeter and band joist. Floor-only applications land lower, around $1,800 – $3,400. We’ll walk the space with you before quoting, so the number matches what’s actually under your house.
Trusted Brands We Service in Inglewood
We carry an eight-brand material bench including Icynene, Demilec, GreenFiber, Owens Corning, Johns Manville, Knauf, Rockwool, and CertainTeed. For Inglewood jobs we lean on Icynene and Demilec for closed-cell acoustic and air-sealing work, and GreenFiber when a customer asks for recycled-content cellulose in the attic. Keeping all these brands on hand means we’re not steering you toward whatever’s cheapest to stock. The spec drives the material, not the other way around. Parts and material for follow-up work are available quickly across all four Inglewood ZIP codes.
Common Spray Foam Insulation Problems We See in Inglewood Homes
- Jet-noise flanking through open wall cavities. Bungalows built before 1950 have empty stud bays, and in the 90301 and 90304 flats under the LAX approach, that means aircraft noise moves through the wall assembly almost unimpeded. Closed-cell foam adds mass and seals the cavity in one pass.
- Marine-layer moisture on rim joists and crawl space framing. The morning marine layer leaves joists damp, and open rim joists pull that air into the floor system. Foam over unaddressed moisture traps rot. We always check moisture content before spraying.
- Radiant heat gain at low-pitch and flat roof decks. Inglewood has a lot of 1920s – 1950s stucco homes with minimal attic space, and the summer sun loads the roof deck hard. Thin or uneven foam leaves hot spots that turn the ceiling into a radiator.
- Unsealed penetrations near remodeled electrical and plumbing. Many of these older homes have been rewired and replumbed multiple times. Every new penetration through a top plate or rim joist is another air and sound leak until foam seals it.
Pricing for Spray Foam Insulation in Inglewood, CA
Here’s what Inglewood homeowners typically pay at today’s material prices. Open-cell spray foam runs $1.10 – $2.10 per board foot installed. Closed-cell runs $2.50 – $4.50 per board foot. A full attic in a 1,200-square-foot bungalow typically lands between $3,800 and $6,800 in closed-cell. Rim joist work runs $900 – $2,800 as noted above. Crawl space perimeter work runs $2,200 – $6,500. The biggest cost drivers are foam depth, access, and whether we’re working around existing mechanicals.

FAQs About Spray Foam Insulation in Inglewood
Yes, closed-cell foam in wall and ceiling cavities measurably reduces jet-noise transmission, but it’s not a cure-all. The foam adds mass and seals flanking leaks around penetrations, which are the main ways low-frequency aircraft rumble enters a home. On a 1940s stucco bungalow off the 90304 flats, our crew pulled the original wall sheathing to find uninsulated cavities on knob-and-tube-era framing and an open rim joist drawing marine-layer air into the floor system. We sealed the rim with closed-cell Icynene and foamed the ceiling plane to add mass against jet noise, then handed the walls back for the drywall and window package the homeowner was already specifying. The foam handles the cavity and flanking path. Windows and wall assemblies still matter. Call (866) 858-4033 and we’ll tell you honestly what your home’s assembly needs.
Because the R-value alone misses the whole job. A 1920s – 1950s Inglewood bungalow has empty wall cavities, open rim joists, and a roof deck that bakes in summer sun. Closed-cell foam air-seals those cavities, which stops both jet-noise flanking and marine-layer air movement. R-value is only part of what the foam is doing. The air barrier and acoustic mass are the rest.
The most common failure is foam over damp wood. Marine-layer humidity in Inglewood keeps crawl space joists damp, and closed-cell foam sprayed directly onto that moisture traps it against the framing. Rot follows. The fix is simple: dry the space first, then foam. We check moisture content with a meter before any crawl space application. Skip that step and you’re buying a much bigger repair later.
Yes, and it’s one of the more common commercial-adjacent jobs we do in Inglewood. Small 2-to-8-unit stucco buildings from the 1950s and 1960s have the same empty wall cavities as the single-family stock, plus party walls that transmit sound between units. Closed-cell foam in the rim joist and ceiling plane cuts both exterior noise from stadium traffic and interior sound transfer between units. The buildings near the stadium also get heavier use now than they did a decade ago, which means air-sealing and moisture control matter more.
Icynene and Demilec for closed-cell acoustic and air-sealing work, especially in the flight-path flats. GreenFiber when the priority is recycled-content blown-in cellulose for an attic top-up. Owens Corning and Rockwool when the job calls for mineral-wool or batt work in specific assemblies. We carry eight brands total so the house drives the spec, not our inventory. Call (866) 858-4033 and ask which one fits your Inglewood home.
