Insulation Company in Inglewood, CA
Blown in insulation is the retrofit workhorse for Inglewood’s older homes, and it’s the service we perform most often across ZIP codes 90307, 90308, 90309, and 90310. The typical Inglewood house was built between 1920 and 1965, which in this trade means open wall cavities, shallow attic floors, and decades of settled or missing material. Ruby Insulation specializes in filling those gaps correctly, matching the right product to the right cavity instead of assuming one material works everywhere. Call (833) 356-0182 for a free estimate.
Why Inglewood Homes Are Different
Inglewood sits directly beneath LAX departure corridors, and that single fact changes what insulation is actually for. Keeping a home cool matters, but keeping the rumble of a 6 a.m. takeoff out of a bedroom matters just as much. Homeowners in the 90301, 90302, and 90303 neighborhoods call us about two problems at once: heat and noise. Dense-pack cellulose and mineral wool both solve the acoustic half better than most people expect.
The housing stock does not offer many shortcuts. Most of what we work on is wood-frame stucco from the pre-war through the mid-1960s, much of it with knob-and-tube-era wall construction and zero cavity insulation. The May and June marine layer pushes damp, cool air through those unsealed walls every morning, and that moisture is the real mold risk if insulation goes in without an air-sealing plan. Homes in the 1950s tracts of 90303 and 90304 often have knee-wall attics with so little clearance that old vermiculite or rock wool has to be spotted, handled carefully, and removed before new material can be blown in. Inglewood is not a speculative new-build market. It is a retrofit market, and the work here rewards a specialist who has seen what lurks inside seventy-year-old walls.
Our Main Inglewood Services
Two services account for most of the calls we take from Inglewood homeowners: attic insulation and spray foam. Each one routes to its own dedicated Inglewood page with full pricing and sub-job detail.
Attic Insulation in Inglewood
Attic work in Inglewood usually means removing old, settled fiberglass or vermiculite from a shallow attic floor and replacing it with a properly rated blown-in material. The low-slope and knee-wall attics common across 90303 and 90304 leave little room for error, and we measure before we quote. Our full breakdown of attic jobs in Inglewood, including what to do about old knob-and-tube wiring and moisture traps, lives on its own page. Attic Insulation in Inglewood
Spray Foam Insulation in Inglewood
Spray foam earns its keep in Inglewood wherever air sealing and moisture control matter as much as R-value. Under a flight path, closed-cell foam applied to the roofline cuts both heat gain and low-frequency noise, and open-cell foam in rim joists stops the damp crawlspace air that feeds mold in older stucco homes. We install Icynene and Demilec systems, both of which require authorized training to purchase. Spray Foam Insulation in Inglewood

Blown In Insulation in Inglewood
Blown in insulation is the fastest, least destructive way to bring a 1920s or 1950s Inglewood house up to a livable thermal envelope. Most of the bungalows and duplexes across 90301, 90302, and 90303 have open wall cavities and uninsulated attic floors, which is exactly the condition blown in material was designed for. For a full national overview of the service, see Blown In Insulation. In Inglewood, the material also pulls double duty as sound control under the LAX flight paths, and dense-pack cellulose in particular makes a measurable difference in bedroom noise levels.
Cellulose Insulation
Signs you need it
Your attic has less than six inches of old, settled material, or your walls are cold to the touch and sound leaks through from outside.
What it costs in Inglewood
Cellulose attic blow-ins in Inglewood typically run $1.50 to $3.50 per square foot of attic floor depending on depth, and dense-pack wall work lands between $2.00 and $4.50 per square foot of wall.
How we do it
We air-seal the attic floor or wall cavities first, then blow GreenFiber recycled cellulose to the target density and depth, checking coverage with a thermal imaging walkthrough.
Blown In Attic Insulation
Signs you need it
Upstairs rooms run ten degrees hotter than the rest of the house in summer, and the attic floor is bare or covered in old, compressed fiberglass.
What it costs in Inglewood
In Inglewood, blown in attic insulation usually falls between $1.50 and $3.50 per square foot, with a typical 1,000-square-foot attic running roughly $1,500 to $3,500 for a standard depth increase.
How we do it
We remove any old material that has settled or gotten damp, seal wiring and plumbing penetrations, then blow the chosen material to a measured R-value across the full attic floor.
Blown In Cellulose Insulation
Signs you need it
You want the acoustic and recycled-content benefits of cellulose specifically, and your walls or attic have accessible cavity access for a blow-in application.
What it costs in Inglewood
Blown in cellulose in Inglewood runs $1.50 to $3.50 per square foot for attics and $2.00 to $4.50 per square foot for dense-pack walls, which includes the added step of cavity drilling or netting.
How we do it
We install either loose-fill in the attic or dense-pack in walls, blowing GreenFiber cellulose at the density that stops settling and provides the sound control Inglewood homes under the flight path need.
What Blown In Insulation Costs in Inglewood
| Item | Typical range in Inglewood |
|---|---|
| Blown in attic insulation (per sq ft) | $1.50 – $3.50 |
| Dense-pack wall insulation (per sq ft) | $2.00 – $4.50 |
| Old insulation removal (per sq ft) | $1.00 – $2.50 |
How long does blown in insulation last in Inglewood’s climate?
Loose-fill cellulose and fiberglass both last 20 to 30 years in Inglewood if the attic stays dry and roof leaks get fixed promptly. Damp marine-layer air trapped in a sealed wall cavity is what shortens that lifespan. Call (833) 356-0182 and we’ll check the existing material before you pay for anything.
Can blown in insulation reduce noise from LAX flight paths?
Yes. Dense-pack cellulose and mineral wool in walls and attic floors meaningfully cut airborne noise, including low-frequency rumble. Older Inglewood homes with hollow wall cavities benefit the most from dense-pack work, and it costs less than a window retrofit. We’ll tell you honestly how much difference to expect in your specific house.
