Fast, Reliable Blown-In Insulation Across Inglewood
Most blown-in insulation jobs in Inglewood run $1,800 to $4,500 for a full attic, and our crew can typically inspect, price, and schedule the work within 48 hours of your call. We dispatch from our Los Angeles office and carry dense-pack cellulose, fiberglass, and full air-sealing kits so we’re not making a second trip for materials. Call (213) 306-2607 and a live person will pick up, 24/7.
We’ve worked the post-WWII bungalows along Crenshaw Boulevard, the ranch homes near Century Boulevard, and the larger lots west of Prairie Avenue where detached workshops sit under the same LAX flight path as the main house. Inglewood’s housing stock and its acoustic challenges are specific, and we price every job in writing before anyone touches a tool.
Why Topside Attic Insulation West Hollywood Is Inglewood’s Preferred Blown-In Insulation Company
Our reputation in Inglewood was built on documentation, not promises. Homeowners here read three-star reviews as carefully as five-star ones, so we publish before-and-after blower-door numbers on every applicable job and deliver a Documented Photo Record on every visit. You see the pressurization reading, the sealed penetrations, and the finished insulation depth, not a verbal summary.
Response time to Inglewood neighborhoods, including the areas near Hollywood Park and the blocks east of La Brea Avenue, is typically same-day or next-day for inspections. Our technicians are background-checked, uniformed, and arrive with a written scope and flat price. Under Haven Standard Clause 1, no work starts without both.
We understand the local conditions that affect blown-in insulation in Inglewood: the original uninsulated wall cavities in 1940s-1960s construction, the marine layer moisture that can degrade old fiberglass batts, and the LAWA sound-insulation program documentation that many homeowners need for grant funding. Wes Okafor has trained our crew on these specs since we opened under The Haven Standard in 2016.
Our Blown-In Insulation Services in Inglewood

Blown-In Cellulose
We install GreenFiber cellulose in Inglewood attics and walls at 1.5 to 2.5 pounds per cubic foot for loose-fill, or at dense-pack pressure for wall cavities. Cellulose performs well acoustically, which matters here more than in most LA Basin cities. A typical attic job in a 1,200-square-foot Inglewood bungalow runs $2,200 to $3,800, including air sealing of top plates and can lights before the blower hose goes in.

Blown-In Fiberglass
We blow Owens Corning and Johns Manville fiberglass for attic top-ups and full replacements where the existing insulation has compressed or degraded. Fiberglass doesn’t settle as severely as cellulose over decades, and it’s the material LAWA’s program often specifies for thermal performance documentation. Most Inglewood attic top-ups with fiberglass run $1,800 to $3,200.

Dense-Pack Wall Insulation
This is our most-requested service in Inglewood, and for specific reason. The city’s post-WWII wood-frame bungalows and ranch homes were built with empty wall cavities, no insulation at all. We drill 2-inch holes at stud spacing, dense-pack cellulose at 3.2 to 3.5 pounds per cubic foot until the cavity is full and firm, then patch and texture-match. The result hits STC ratings that matter for LAX noise reduction. A full dense-pack on a 1,000-square-foot Inglewood home runs $3,500 to $5,500.

Blown-In Top-Up
Many Inglewood attics have some old fiberglass or rock wool, but it’s compressed to R-11 or R-19 and no longer effective. We remove debris, air seal, then blow new material over the top to reach R-38 or R-49 per current Title 24 guidance. This is the most cost-effective upgrade for homeowners who don’t need full replacement. Typical range: $1,800 to $3,000.

We stock Owens Corning, Johns Manville, and Knauf products on our Inglewood-area trucks, plus GreenFiber cellulose for dense-pack work. No proprietary lock-in means we match the material to your home’s condition and any LAWA program requirements, not to a single supplier’s inventory. Our Los Angeles warehouse turns orders fast, so we’re not delaying your job for a back-ordered batt size.
Common Blown-In Insulation Problems We See in Inglewood Homes

- Loose-fill fiberglass dumped into wall cavities without dense-packing. This leaves voids at the top and bottom of studs, does almost nothing for sound transmission, and fails LAWA’s STC verification. We see this shortcut on homes near Florence Avenue where acoustic performance was the whole point of the job.
- Detached workshops and garage door frames left unsealed. Inglewood’s larger lots, especially west of Prairie Avenue, often have rear structures with oversized or heavy doors that were never insulated at the frame perimeter. Blowing attic insulation while ignoring these gaps lets air, sound, and moisture keep moving.
- Missing LAWA program documentation. Contractors who don’t learn the Residential Sound Insulation Program’s specs, approved STC ratings, and required paperwork disqualify homeowners from grant funding. We complete the documentation as part of our scope.
- Insulating over unsealed attic floors. We don’t blow anything until top plates, plumbing penetrations, and can lights are sealed. The blower-door test tells us when we’re done, not a visual guess.

FAQs - Blown-In Insulation in Inglewood

Yes, dense-pack blown-in insulation significantly reduces aircraft noise transmission, and in Inglewood that’s often the primary reason homeowners install it. The STC rating improvement from filling empty wall cavities with cellulose at 3.2+ pounds per cubic foot, combined with attic air sealing, dulls the LAX approach noise that penetrates uninsulated wood-frame construction. Call (213) 306-2607 and we’ll measure your current wall insulation, if any, and quote the acoustic upgrade.
LAWA’s program is an FAA-funded grant that covers acoustic insulation upgrades for homes within LAX’s 65+ dB CNEL noise contour, which includes most of Inglewood. The program pays for qualified insulation work, windows, and doors when installed to approved STC specs and documented correctly. We know the program’s material and paperwork requirements and complete the documentation as part of our standard scope. Call (213) 306-2607 to check your eligibility and get a written price that aligns with program guidelines.
Almost certainly not. Inglewood’s residential core was built before California required wall insulation, and the wood-frame bungalows and ranch homes from the 1940s through 1960s typically have empty wall cavities. We verify this with a borescope inspection through a small hole before quoting. Dense-pack drill-and-fill is the standard retrofit for these homes. Call (213) 306-2607 for a free inspection.
Yes, and we specifically address the air and sound leaks around heavy door frames that most insulation crews ignore. Inglewood’s larger lots, particularly west of Prairie Avenue, often have rear structures with doors that were never sealed or insulated at installation. We dense-pack the walls, blow the ceiling, and seal the frame perimeter in one trip. Call (213) 306-2607 for a written scope on your workshop.
The thermal ROI in Inglewood is modest compared to inland cities because summer highs stay in the mid-70s to low 80s and winter heating loads are light. We don’t oversell energy savings here. The acoustic benefit from LAX noise reduction is the stronger financial and comfort argument for most Inglewood homeowners, and we price and scope accordingly. Call (213) 306-2607 for honest numbers on your specific home.
