Insulation Company in Culver City, CA
Blown in insulation solves the core problem we see across Culver City: 1920s and 1930s bungalows with empty wall cavities and attics that bake in the LA Basin heat. We’re Fontana Insulation, and we’ve served Culver City since 2011. The job here is rarely about freezing winters. It’s about summer heat gain, noise from neighbors ten feet away, and energy bills that climb every August. Call (866) 271-1602 for a free estimate on blown in insulation, attic work, or spray foam.
Why Culver City Homes Are Different
Culver City’s housing stock sits on narrow lots with homes close enough to hear a neighbor’s dishwasher. The 90232 and 90230 ZIPs hold dense clusters of 1920s to 1940s California bungalows built with lath-and-plaster walls and no cavity insulation at all. Many still have original vented attics with nothing between the ceiling and the roof deck. The 90231 and 90233 areas add 1950s and 60s ranch homes with shallow wall cavities and early drywall, plus some newer infill construction.
The climate is mild and marine-influenced, which means insulation here is a heat-gain and sound problem, not a deep-winter problem. Homes face warm-to-hot summers that push attic temperatures past 140 degrees. We also work with Culver City’s wildfire-zone building requirements around ember-resistant venting. When a bungalow on a tight lot gets retrofitted, the work is about accessing old walls, dense-packing the right material, and making sure vents don’t invite embers in. The payoff is a cooler second floor, a quieter living room, and HVAC equipment that doesn’t run all afternoon.
Our Main Culver City Services
Most Culver City homeowners call us about two services: attic insulation retrofits on older homes, and spray foam for air-sealing and hard-to-reach areas. Both come with a material-agnostic recommendation, because we stock eight brands and match the product to the house rather than the other way around.
Attic Insulation in Culver City
Older Culver City attics often have nothing between the ceiling joists or a thin layer of 1940s fiberglass that’s settled to half its original depth. We assess what’s there, check venting against current wildfire-zone practices, and install blown in or batt insulation to hit a sensible R-value for this climate. For homes near the 405 or along Venice Boulevard, this work also knocks down road noise. See the full breakdown at Attic Insulation in Culver City.
Spray Foam Insulation in Culver City
Spray foam earns its place in Culver City on additions, rim joists, and rooms where air leaks are the real issue. Closed-cell foam also helps in crawlspaces under older bungalows where moisture and rodent entry are concerns. We’re an authorized installer for Icynene and Demilec, two of the most performance-tested foam brands in North America. Read more at Spray Foam Insulation in Culver City.

Blown In Insulation in Culver City
Blown in insulation is the workhorse for Culver City’s older bungalow blocks. In 90232 especially, we regularly open original wall cavities that have never held insulation in the nearly 100 years since the home was built. Blown In Insulation lets us dense-pack those walls without gutting lath-and-plaster, and it’s the fastest way to bring a vented attic up to a useful R-value for summer heat gain. Craftsman-era homes with shallow framing and no vapor barrier respond well to this method, because the material conforms to cavities batt insulation can’t fill.
Cellulose Insulation
Signs you need it
Rooms that heat up by mid-afternoon, walls that feel warm to the touch on summer evenings, and sound that travels freely between closely spaced homes.

Dense-pack cellulose for walls and attics in Culver City typically runs $1.50 to $3.00 per square foot installed, depending on cavity depth and access.
How we do it
We drill small access holes in each stud bay or attic surface, dense-pack GreenFiber cellulose to a verified density, then patch and finish the openings to match.
Blown In Attic Insulation
Signs you need it
An attic that turns bedrooms below into ovens by 3 p.m., HVAC ducts that sweat in summer, and old fiberglass that’s settled flat between the joists.

We remove small sections of siding or drill through plaster, dense-pack material into each cavity at pressures that prevent settling, then restore the surface.

How we do it
We lay down a consistent layer of loose-fill material across the entire attic floor, covering bypasses and low spots that batts leave open.

Is blown in insulation worth it for Culver City’s mild climate?
Yes. The payoff is summer heat-gain control and HVAC efficiency, not winter warmth. A well-insulated attic can keep second-story rooms 10-15 degrees cooler and cut peak-season cooling costs. The exact savings depend on your home’s current insulation and duct condition.
Can you blow insulation into old walls without gutting them?
Yes. Dense-pack blown in insulation goes through small access holes in the siding or plaster, then we patch and restore the surface. It’s the standard method for 1920s-1940s Culver City bungalows with lath-and-plaster walls. Call (866) 271-1602 for a wall cavity assessment.

What Culver City Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"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."
— Sarah Fletcher"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."
— Holly Mercer
