Spray foam insulation in Culver City costs roughly $1,800 to $6,400 for a typical wall or rim joist retrofit, depending on square footage, foam type, and whether we’re working around old wiring.

Why Laurel Attic Insulation Los Angeles Is Culver City’s Preferred Spray Foam Insulation Company
Culver City sits inland from the 405, away from the coastal marine layer that keeps Venice and Santa Monica cool. That means hotter summer afternoons and chillier winter nights than people expect a few miles west. We’ve crawled through enough attics here to know the local failure pattern by heart: original knob-and-tube wiring, blackened fiberglass batts that concealed overheated circuits, and uninsulated 2×4 walls with nothing but wood lath and plaster between you and the outside air.
Chase Whitaker leads our Los Angeles crew, and the team has worked behind the Sony Pictures lot, up through Blair Hills, and across the flats near downtown Culver City. Our 365-Day Done Right Promise means if a spray foam job isn’t right, we make it right, in writing, on every single invoice. Culver City customers get the full Relay Visibility Guarantee: live arrival tracking, before-and-after photos, and a written price before a single staple is set. About that price: it’s not an estimate you’ll “find out about later.” It’s a fixed number, delivered before we start, every time.
Spray Foam Wall Insulation in Culver City
Spray foam wall insulation in Culver City is the fix for the single biggest comfort complaint in the city’s 1940s-to-1970s housing stock: uninsulated 2×4 walls that let afternoon heat pour straight through stucco and wood lath into bedrooms and living spaces. Most wall retrofits in Culver City run $2,200 to $5,800 depending on the number of exterior walls and whether we’re drilling through plaster or working from the exterior stucco side. Here’s the local truth: Carlson Park and Vets Park homes built in the 1950s frequently have no sheathing behind the stucco, just wood lath strips and plaster. That’s a challenge for some crews. For ours, it’s a normal Tuesday.
Direct Foam-to-Lath Adhesion
When there’s no sheathing, the foam bonds directly to the back of the wood lath strips and the plaster keys. Done carefully, that gives you a continuous air seal across the entire wall cavity. Done poorly, it leaves voids between lath strips that become thermal bridges on hot afternoons.
What Open-Cell Foam Does in Old Plaster Walls
We use open-cell spray foam, typically Demilec, for these older lath-and-plaster retrofits. Open-cell is forgiving: it expands gently, won’t bow the plaster, and still delivers an R-value around 3.7 per inch. In a 2×4 cavity that’s about R-13, which is roughly double what you’re getting now if you’re getting anything at all.
Rim Joist Spray Foam in Culver City
Rim joist spray foam in Culver City tackles the drafty band of wood where your floor framing meets the foundation wall, and in a 1940s stucco home it’s often the single largest air leak in the whole house. A typical rim joist job in Culver City runs $900 to $2,200 for a standard crawlspace or basement perimeter, and it’s usually finished in under four hours. Culver City’s diurnal temperature swing means cool winter nights pull cold air straight through an unsealed rim joist, and summer afternoons do the reverse, dragging heat into the crawlspace and up through the floor.
Why Closed-Cell Wins at the Rim
At the rim joist, we prefer closed-cell spray foam. It’s denser, acts as its own vapor retarder, and adds structural rigidity to the framing connection. For a 1940s stucco Culver City home, closed-cell rim joist foam also cuts the stack effect that pushes hot air from the crawlspace into the upper floors.
One Job off Braddock Drive
In a 1954 stucco home off Braddock Drive in Carlson Park, we paired a rim joist seal with an open-cell wall retrofit. The homeowner’s bedroom over the garage had been running 12°F hotter than the rest of the house every summer afternoon. We drilled through the original wood lath and plaster, pumped Demilec open-cell into the uninsulated 2×4 walls, closed the cavities with foam plugs, and sealed the rim. Within the first week, we measured a 6°F differential. Not perfect, but a massive shift for a 70-year-old house.
Trusted Brands We Service in Culver City
We stock and spray Owens Corning, Rockwool, and Demilec products for Culver City jobs, and we’ll match the material to the job rather than whatever is already on the truck. Open-cell Demilec for lath-and-plaster wall retrofits. Closed-cell Owens Corning for rim joists and roof decks where you need vapor control and rigidity. Rockwool comes into play on projects where fire resistance or sound control is the priority, and Culver City’s mix of older single-family homes and newer mixed-use buildings along the transit corridors means we see both. Same-day material pickup from our Los Angeles yard keeps turnaround fast for Culver City customers.
Common Spray Foam Insulation Problems We See in Culver City Homes
- Blackened fiberglass over old knob-and-tube wiring. Culver City attics from the 1940s and 1950s frequently have original knob-and-tube circuits. The old fiberglass batts around them get dark and compressed, which means heat was building up for years. Spray foam applied directly over live knob-and-tube can trap that heat and create a fire hazard, so we always inspect and flag it before any foam goes in.
- Uneven foam expansion between wood lath strips. In Vets Park and Carlson Park, uninsulated 2×4 walls have plaster over wood lath with no sheathing. If the foam expands unevenly between lath strips, you get small voids that act as thermal bridges on hot afternoons. We account for that with slower, staged passes and cavity-depth checks.
- Moisture trapping behind stucco exteriors. Many 1940s-era Culver City stucco homes have no drainage plane behind the stucco. Closed-cell foam applied to the interior face of a stucco wall without proper moisture management can trap water vapor against the framing during cool winter nights. This is one reason we lean toward open-cell in those older wall cavities.
- Heat stack effect from garage to bedroom. Bedrooms over garages in Culver City routinely run 10 to 15 degrees hotter in summer because the garage ceiling, the floor assembly, and the shared wall are all uninsulated. That’s not a ventilation problem. It’s a thermal envelope problem, and spray foam on the garage ceiling and rim joist is the direct fix.

FAQs About Spray Foam Insulation in Culver City
Yes, spray foam fixes most of it. The bedroom sits directly above an unconditioned garage, and in Carlson Park’s 1950s homes the garage ceiling, the floor framing, and the shared wall all lack insulation, so heat rises from the garage slab and radiates up through the floor. We spray foam the garage ceiling and the rim joist, and often the shared wall too. Most homeowners see a 5 to 8 degree drop within the first week. Call (213) 698-7067 for an exact quote, free of charge.
Yes. We drill through the plaster and lath from the exterior side or through the wall cavity, inject open-cell spray foam into each stud bay, and plug the injection holes with foam. The plaster stays in place. It requires care to avoid over-expansion that could bow the plaster, which is why we use open-cell and stage the passes slowly on lath-and-plaster walls. It’s a specialized approach we’ve done dozens of times in Vets Park and Carlson Park.
No, not over live knob-and-tube. Spray foam encases the wiring and prevents heat from dissipating, which can overheat the circuit and create a fire hazard. In Culver City homes with original knob-and-tube, we inspect the attic first. If the wiring is live, we’ll flag it and recommend an electrician evaluate it before any foam goes near it. If the wiring is abandoned and dead, we can typically proceed. Safety comes before foam, always.
Closed-cell spray foam. It’s denser than open-cell, acts as its own vapor retarder, and seals the rim joist completely against air movement. For a 1940s stucco home without a drainage plane, closed-cell at the rim also keeps ground moisture from wicking up into the framing. A typical rim joist perimeter in Culver City runs $900 to $2,200.
Spray foam outperforms fiberglass in Culver City’s inland climate because it air-seals while it insulates. Fiberglass batts only slow heat transfer; they don’t stop air movement. In Culver City’s summer, that air movement through unsealed walls and rim joists is exactly what makes the house heat up. Open-cell spray foam in a 2×4 wall delivers about R-13 and stops the air leaks, which is why it beats what’s currently in most 1950s Carlson Park walls: nothing. Free estimates at (213) 698-7067.
