Insulation Company in Inglewood, CA
Fountain Valley Insulation installs blown-in insulation, attic insulation, and spray foam across Inglewood, CA, with a focus on jobs most LA-area contractors never touch: sound-rated wall cavities near LAX, moisture control in 1940s and 1950s stucco tract homes, and dense-pack filling for post-war framing that was never built for modern comfort. If your Inglewood home runs warm in summer, stays damp in the marine layer, or lets jet noise leak through walls and attic seams, call (833) 390-3099. We match the material to your home, not the other way around.
Why Inglewood Homes Are Different
Inglewood sits in a marine-influenced coastal climate where the thermometer rarely swings hard, but the work insulation does changes completely. In most of the country, insulation is bought and installed for thermal resistance. Here, the real job is condensation control, sound attenuation, and air sealing. The marine layer pushes damp, cool air against stucco walls and into under-ventilated attics for months at a time. Older stucco-and-drywall assemblies from the 1940s through 1960s were framed fast, with minimal cavity depth and no vapor management. When warm indoor air meets those cool exterior walls, moisture condenses inside the wall cavity, and that leads to mold, musty smells, and drywall that feels soft to the touch.
Housing stock varies block by block in Inglewood. The 90301 and 90302 ZIP codes hold a large share of pre-war bungalows and mid-century single-story tract homes, many with original framing and either no wall insulation or a thin layer that has settled into uselessness. The 90303, 90304, and 90305 ZIP codes include a growing number of newer multi-family and rebuilt infill projects, where insulation scope and code requirements differ completely from a 1955 bungalow. Technicians working in the airport-facing neighborhoods routinely find that the homeowner’s biggest complaint is not temperature but jet noise. That changes what we specify: dense-pack wall cavities, sound-rated batts, and tight air sealing around every penetration.
Our Main Inglewood Services
Most Inglewood homeowners call us for one of two jobs: attic insulation upgrades in the older housing stock, or spray foam for the moisture and sound problems that fiber-only contractors never solve. Each has its own page for this city.
Attic Insulation in Inglewood
Older Inglewood attics tend to have a thin layer of settled fiberglass, if they have anything at all. The bigger problem is the attic access hatch, recessed can lights, and wiring penetrations that let conditioned air escape and marine-layer dampness in. In the neighborhoods closer to LAX, the attic also acts like a drumhead for aircraft noise, transmitting sound straight into the living space below. We inspect framing, ventilation, existing material, and then recommend what actually fits: blown-in coverage, batts, or air sealing first. Read the full breakdown on our Attic Insulation in Inglewood page.
Spray Foam Insulation in Inglewood
Spray foam earns its keep in Inglewood when a home has uninsulated walls, a crawlspace that breathes damp air, or a homeowner who wants the tightest possible air seal against both jet noise and marine-layer moisture. We install closed- and open-cell foam through Icynene and Demilec, two brands most general insulation companies do not carry. The material expands into every stud bay, rim joist, and awkward cavity, which matters in older Inglewood framing where nothing is square. See the details on our Spray Foam Insulation in Inglewood page.

Blown In Insulation in Inglewood
Blown in insulation is the workhorse solution for most Inglewood attics and the only practical way to insulate the wall cavities of an older home without tearing out drywall. In a 1950s stucco ranch near Centinela Avenue or a pre-war bungalow off Manchester Boulevard, blown-in material reaches around original framing, settles into the odd-shaped spaces, and costs significantly less than spray foam. For Inglewood specifically, we always account for the marine layer: blown-in fiberglass and cellulose both need proper attic ventilation above them, or trapped moisture will degrade the material and the framing it touches. Our crew dense-packs wall cavities in the airport-facing neighborhoods because loose fill in a stud bay does far more for sound when it is packed tight, not blown loose. If you want the full picture on material options, start with our Blown In Insulation overview.
Cellulose Insulation
Signs you need it
Your attic has old, settled fiberglass that is original to a mid-century Inglewood home, and your upstairs rooms stay warm even when the marine layer keeps outdoor temperatures mild.
What it costs in Inglewood
Cellulose insulation in Inglewood attics and wall cavities typically runs $1.10 to $1.80 per square foot installed, depending on depth and access.
How we do it
We air-seal the attic floor, verify ventilation, then blow GreenFiber recycled cellulose to the specified depth and density, including dense-pack wall cavities where sound control matters.
Blown In Attic Insulation
Signs you need it
The attic floor has bare spots or less than six inches of material, and rooms below trap heat or let aircraft noise through the ceiling.
What it costs in Inglewood
Blown in attic insulation in Inglewood generally lands between $1.50 and $3.50 per square foot installed, with most whole-attic jobs in older homes falling between $1,800 and $4,200.
How we do it
We remove or top up failing material, seal penetrations and the attic hatch, install vent baffles at the eaves, and blow the covering to the R-value that fits your home and budget.
Blown In Cellulose Insulation
Signs you need it
You want a denser, sound-attenuating fill than fiberglass, particularly in a home between La Brea and Prairie Avenues where jet noise is constant.
What it costs in Inglewood
Blown in cellulose runs $1.10 to $1.80 per square foot installed in Inglewood, and dense-pack wall applications sit at the higher end of that range.
How we do it
We use GreenFiber cellulose, a recycled-content product, and blow it to either loose-fill depth in attics or dense-pack density inside wall cavities, depending on the job.
Loose Fill Insulation
Signs you need it
Your attic floor has uneven coverage or compressed sections where old material has flattened over time, and you can feel air movement at ceiling fixtures.
What it costs in Inglewood
Loose fill insulation in Inglewood typically costs $1.40 to $2.80 per square foot installed for attic applications.
How we do it
We prep the attic floor, seal bypasses, mark depth, and blow loose fill to an even, consistent layer across the full attic footprint.

Does blown in insulation help with jet noise in Inglewood?
Yes, especially dense-pack cellulose in wall cavities and a thick loose-fill layer across the attic floor. The mass of the material interrupts the sound path that travels through framing and ceiling drywall. Call (833) 390-3099 for an exact quote on your home’s layout.
Can you install blown in insulation the same week in Inglewood?
In most cases, yes. We schedule blown-in jobs throughout Inglewood weekly, and single-attic jobs usually take one day. Larger wall-cavity dense-pack work may add a second day. Call (833) 390-3099 to check current availability.
Brands We Service in Inglewood
We carry and install Rockwool mineral wool, CertainTeed fiberglass, Icynene and Demilec spray foam, and GreenFiber recycled cellulose across Inglewood. Because we work with eight manufacturer brands rather than one house line, we stock what each job actually needs and can get specialty materials fast. See our brands or ask us why we carry Rockwool, spray foam, and recycled fiber when most contractors carry none of them.

What Inglewood Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Hector Vargas"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"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."
