Fast, Reliable Spray Foam Insulation Across Inglewood
Spray foam insulation in Inglewood typically runs $2.80 – $6.50 per board foot installed, with a full 1,200-square-foot attic usually landing between $3,400 and $7,800 depending on open-cell or closed-cell, and most homes can be done in one to two days. That’s the honest range, and it holds across 90301, 90302, 90303, 90304, and 90305. If you’re losing the battle against aircraft rumble from the LAX arrival corridor or the constant low-frequency growl of Century and La Cienega traffic, the right foam application changes how your walls and attic behave.

Why Orange County Insulation Is Inglewood’s Preferred Spray Foam Insulation Company
We only do insulation. No roofing, no HVAC, no remodeling work pulling our attention away. Every crew member who steps onto an Inglewood job site spends every working day installing, air-sealing, and retrofitting thermal and acoustic envelopes. That single-trade focus means we’ve seen the specific failure patterns of 1920s stucco bungalows off Crenshaw, the piecemeal attic rehabs in the 90301 flats, and the thin-wall townhome infill going up off La Brea.
Inglewood homeowners call us because the spray foam conversation here is different from other parts of the South Bay. A home under the LAX departure path needs sound attenuation as much as thermal gain control. If you’ve had another contractor quote batts and move on, you haven’t had the conversation we’ll have with you. Noel Carrasco, who leads our crew, has spent years matching the right foam type to the actual wall assembly and noise load of each house. We’re state-licensed, insured, and bonded, and our track record across Inglewood is built on jobs that actually changed how a house feels, not just what the invoice says.
Open Cell Spray Foam in Inglewood
Open Cell Spray Foam in Inglewood is the workhorse for attic roofs, top plates, and joist-bay air-sealing in the 1920s through 1950s stucco bungalows that dominate the 90301 and 90302 flats. It’s a lighter-density foam that expands to fill odd cavities, which matters when you’re dealing with plaster-over-wire-lath construction that was never framed to modern dimensions. Open-cell runs $2.80 – $4.50 per board foot installed, and a typical 1,000-square-foot attic job in Inglewood lands around $2,800 – $4,500. It’s not a structural barrier, but it’s the right tool when the goal is sealing air movement and cutting the low-frequency drone that makes its way through unsealed top plates and kneewalls.
Attic Top-Plate Sealing
Inglewood homes that got attic insulation in the 1970s or 80s often have fiberglass blown over open joist bays with no air-sealing underneath. That leaves a direct acoustic path from the attic into the living space. We cap those top plates and joist bays with open-cell Icynene, which gaskets the framing and stops the air channel that carries aircraft rumble and Century Boulevard traffic noise into the bedrooms.
Noise-Buffering Wall Cavities
When a homeowner off La Cienega asks us to cut the low-frequency load in a 1940s plaster bungalow, open-cell sprayed into the wall cavities behind a new drywall layer adds meaningful acoustic damping. It won’t replace resilient channels on the worst LAX-contour homes, but it takes the edge off the constant hum and helps the house hold its conditioned air. We install this as part of a controlled retrofit, never as a spray-and-pray over old plaster that needs to breathe.
Spray Foam Insulation Contractors in Inglewood
Spray Foam Insulation Contractors in Inglewood shouldn’t be generalists with a foam rig in the back of a pickup. The city’s building stock, mostly 1920s plaster-over-lath stucco, demands a contractor who knows when open-cell is the right call, when closed-cell earns its cost, and when spray foam is the wrong material altogether. A closed-cell application in Inglewood runs $4.20 – $6.50 per board foot installed, with a rim joist or garage ceiling job typically $1,800 – $4,200. The reason our team gets called in for re-dos is almost always the same: someone sprayed without a vapor and air-sealing plan, or they sprayed single-layer drywall and called it a day, and the client still feels every arriving 737.
Closed-Cell in Garage Ceilings and Rim Joists
Inglewood’s lot lines are tight, and many garages sit directly under occupied bedrooms. A garage ceiling sprayed with closed-cell Demilec does double duty: it’s a thermal break against the afternoon heat that radiates off west-facing stucco and it dampens the structural transfer of alley and street noise. Rim joists are the other place we spec closed-cell often, because they’re the leaky seam where the 1920s crawlspace framing meets the foundation, and open-cell’s permeability isn’t the right fit.
Retrofit-Sealed Roof Decks
Some Inglewood bungalows have unvented attic conversions done in the 60s and 70s, where the roof deck itself becomes the insulation plane. On those homes, we spray closed-cell directly under the roof sheathing. It stiffens the deck, seals the tile or shingle assembly from interior moisture, and creates a single monolithic air barrier that actually works in the marine-influenced coastal edge climate, where the real summer problem is radiant heat gain, not cold-weather loss.
Trusted Brands We Service in Inglewood
We stock and install foam from Icynene and Demilec, which covers both open-cell and closed-cell applications with products we’ve tested in Inglewood’s specific conditions. When a job calls for something other than foam, we also work with GreenFiber cellulose and Owens Corning batts, because the right answer isn’t always spray foam. We keep materials on hand for Inglewood jobs so we aren’t waiting on a supplier in Torrance to release a pallet. For Inglewood homeowners, that means the crew lands with the right product ready to spray, and you’re not paying for a second mobilization because the material wasn’t on the truck. That’s what single-trade specialization looks like in practice.
Common Spray Foam Insulation Problems We See in Inglewood Homes
- Closed-cell sprayed directly against old stucco-and-plaster without a vapor plan. This is the most common failure we’re called to fix in the 1920s – 1950s bungalows. The foam traps moisture inside the cavity, and six months later the lath is rotting and the exterior paint is blistering. It’s a materials science problem, not a workmanship problem, but it’s also fully avoidable.
- Attic rehabs that skip top-plate and joist-bay sealing. A piecemeal 1970s attic retrofit with open-cell foam over unsealed top plates still lets low-frequency aircraft noise flow through the thermal envelope. Homeowners think they got a bad foam job, when actually they got an incomplete one.
- Single-layer drywall over foam in LAX-contour homes. This meets the R-value target on paper and fails acoustically in real life. If you’re on the flight path, one layer of 5/8-inch drywall over foam is not enough. We routinely spec double-layer drywall plus resilient channels for these jobs.
- Small 1960s – 70s apartments with uninsulated framing cavities. We see this across 90304 and 90305, especially in fourplexes and small apartment buildings where the original construction never included cavity insulation. The wall framing is empty, the stucco radiates heat in the afternoon, and the tenants hear every car on the side street. Dense-pack or open-cell retrofits change that.
Pricing for Spray Foam Insulation in Inglewood, CA
Open-cell spray foam in Inglewood runs $2.80 – $4.50 per board foot installed, and closed-cell runs $4.20 – $6.50 per board foot installed. A typical 1,000 to 1,200-square-foot attic job lands between $2,800 and $8,000, depending on which foam we spec, whether we’re air-sealing top plates, and whether the roof deck is accessible. A garage ceiling spray foam job in Inglewood typically runs $1,800 – $4,200. A rim joist package across a standard crawlspace is usually $1,400 – $3,000. What moves the number: the age of the wall assembly, whether we’re pulling plaster for a dense-pack retrofit, and whether the home sits directly in the LAX noise contour and needs an acoustic assembly, not just thermal air-sealing.

FAQs About Spray Foam Insulation in Inglewood
Yes, but only when the application is designed for acoustics, not just thermal R-value. The low-frequency rumble from arrivals and departures moves through framing, not just air, so closed-cell against a roof deck or open-cell in wall cavities does part of the job, but the meaningful reduction comes from sealing top plates, dense-packing empty wall cavities, and adding a double layer of 5/8-inch drywall on resilient channels. On the worst-contour homes off La Cienega, we’ve watched a “constant” drone drop to a background hum. Call (877) 680-3557 to talk through whether your specific block warrants that full assembly or a lighter touch.
Because the original wall cavities in those 1920s – 1950s plaster-over-wire-lath homes are irregular, and fiberglass batts won’t fill them completely. Batts leave voids at the corners and around framing, which become air channels that carry noise and heat. Dense-packed GreenFiber cellulose conforms to the cavity, and open-cell Icynene gaskets it. In a 1940s bungalow off La Cienega, we pulled the plaster at the seams, dense-packed the empty cavities, and closed with two layers of drywall, and the difference was immediate. In those walls, batts are a false economy.
Yes, but it requires planning. The failure we see from other contractors is closed-cell foam sprayed directly against the back of old stucco-and-plaster without an air-sealing plan or a vapor management strategy. That traps moisture from interior humidity and exterior rain penetration inside the cavity, and the lath rots. We don’t do that. We design the assembly, which often means open-cell or dense-pack in the walls with the right interior finish, not closed-cell against the back of the plaster. The material choice depends on the wall’s orientation, the stucco condition, and whether there’s existing moisture. No responsible contractor gives a blanket “spray it all” answer on these homes.
For many Inglewood homes, the honest answer is that attic air-sealing plus a proper insulation layer is the highest-return first step. The climate rarely freezes and rarely hits extremes, so the thermal load is moderate, and the real pain is summer heat gain through uninsulated attics and the noise. But if you’re directly under the LAX corridor or on a busy arterial like Century or Prairie, spray foam plus an acoustic drywall assembly does something air-sealing alone cannot, because it adds mass and damping to the wall itself. We’ll tell you if you don’t need the foam. That is literally our job, match the material to the situation.
Open-cell, which we install primarily with Icynene, is lighter, expands more, and is our default for attic top plates, joist bays, and wall cavities where we need gasketing and acoustic damping. It runs $2.80 – $4.50 per board foot. Closed-cell, installed with Demilec, is denser, acts as a vapor retarder to manage moisture ingress, adds structural rigidity, and is the right material for rim joists, garage ceilings under bedrooms, and unvented roof decks. It runs $4.20 – $6.50 per board foot. The spec isn’t a preference, it’s a function of where the assembly sits and what’s trying to get through it. Call (877) 680-3557 and we’ll walk you through which one your house actually needs.
