Insulation Company in Culver City, CA
Blown in insulation is the most common fix for Culver City’s 1940s and 1950s homes, because the original rock-wool or foil-faced batts in those attics have usually slumped, compacted, or simply disappeared over 70 years of marine-layer humidity. We install blown-in cellulose and fiberglass across Culver City’s 90230, 90231, 90232, and 90233 ZIP codes, matching each house to the right material rather than forcing one product onto every job. Hollywood Insulation Co has served Culver City since 2018, and you can reach us at (866) 605-6949 for a free estimate.
Why Culver City Homes Are Different
Culver City’s housing stock sits squarely in the post-WWII building boom, when whole tracts went up quickly around the old MGM lot and the Helms Bakery corridor. Those homes, mostly 1940s to 1960s stucco-clad bungalows with raised wood floors and exposed attic joists, were built when insulation was an afterthought. Many still have the original rock-wool batts in the rafters, now sagging and compressed to a fraction of their original R-value. On top of that, Culver City’s coastal-influenced basin brings cool nights, morning marine-layer humidity, and mild damp winters. That means insulation here isn’t just about staying warm in January. It’s about keeping moisture from condensing inside unvented attic cavities, cutting street noise from dense westside traffic, and stopping the afternoon heat from baking upstairs bedrooms. The stucco and plaster walls common to these older homes also make adding wall insulation much trickier than in newer construction, which is why attic and blown-in upgrades deliver the most immediate results.
Our Main Culver City Services
The two services Culver City homeowners call about most are attic insulation and spray foam, and each has its own dedicated page with full pricing and local detail.
Attic Insulation in Culver City
Most Culver City attics we see have either fiberglass batts that were installed decades ago and have compressed, or loose-fill that’s settled to a thin layer at the bottom of the joist bays. Working south of Venice Boulevard especially, we find the original foil-faced or rock-wool product still sitting behind the plaster when garages and attics get converted into studios or offices, and that old material has to come out before anything new goes in. Read the full breakdown on our Attic Insulation in Culver City page.

Spray Foam Insulation in Culver City
Spray foam earns its place in Culver City when a homeowner is converting a garage, finishing an attic, or building an ADU behind the main house and needs both air sealing and high R-value in a limited cavity depth. Closed-cell foam from Icynene or Demilec also handles the moisture concerns that come with the marine layer, since it acts as its own vapor barrier. See what’s involved on our Spray Foam Insulation in Culver City page.

Blown In Insulation in Culver City
Blown in insulation in Culver City is the fastest way to bring an under-insulated attic up to current standards without tearing open walls or ceilings, which matters in older stucco-and-plaster homes where wall retrofits are invasive and expensive. Most of the original batts in these 1940s and 1950s attics have slumped or compacted, leaving gaps that let conditioned air leak straight through the ceiling, and blown-in cellulose or fiberglass fills every irregular joist bay and corner in a single pass. We install both materials across Culver City, and our Blown In Insulation service comes with an honest recommendation based on your home’s actual ceiling structure and climate exposure, not what’s left on the truck.
Cellulose Insulation
Signs you need it
Your attic has thin, uneven coverage, you can see the tops of the ceiling joists, and upstairs rooms run noticeably hotter than the rest of the house in late summer.
What it costs in Culver City
Cellulose insulation in Culver City typically runs $1.50 to $3.50 per square foot installed, depending on depth and access.
How we do it
We air-seal the major bypasses first, then blow GreenFiber recycled cellulose to the specified depth across the entire attic floor using a calibrated hose and density checks.
Blown In Attic Insulation

How we do it
We remove any failed or compressed old material when needed, seal the top plates and penetrations, then blow fresh insulation to R-38 or R-49 depth, depending on the zone and your budget.
Blown In Fiberglass Insulation
Signs you need it
The existing fiberglass batts have collapsed, or there are gaps around wiring, recessed lights, and the attic hatch where air moves freely.
What it costs in Culver City
Blown in fiberglass insulation in Culver City costs roughly $1.20 to $3.00 per square foot installed, with the final number set by depth and prep work.

We blow loose-fill fiberglass from Owens Corning or Johns Manville at an even density to the target depth, then level it across the joist bays and recheck the coverage.

Signs you need it
Your attic has settled loose-fill that’s compacted to a dense, air-leaky mat, or some areas are bare while others are overfilled.

What Culver City Customers Say
"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."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Miguel Garcia
