Fast, Reliable Spray Foam Insulation Across Lawndale
Spray foam insulation in Lawndale typically runs $2.50 to $6.50 per square foot installed, depending on whether the job calls for open-cell or closed-cell foam, and most attic retrofits on the city’s 1950s stucco homes land in the $3,800 to $8,500 range. We service all of Lawndale, from the 90260 side streets off Hawthorne Boulevard to the 90261 blocks near Marine Avenue, usually with same-week scheduling. If your attic still has the original 1950s batts or nothing at all, call us at (866) 605-6949 and we’ll tell you straight whether spray foam is the right fix or whether you’d be better served by blown-in or batt work.
Why Hollywood Insulation Co Is Lawndale’s Preferred Spray Foam Insulation Company
We’re insulation specialists, not a general contractor who picks up a spray rig on slow weeks. Every job we run in Lawndale starts with the same question: what is this house actually doing wrong? On a 1952 stucco bungalow off a 90260 side street, our crew found a shallow-pitch roof over an attic where the original batts had sagged and been tunneled through by rodents, with fog-dampened sheathing and condensation staining along the north slope. We pulled the compacted batts, air-sealed the party-wall and top-plate penetrations, dried the deck, then laid closed-cell Icynene against the sheathing and finished with Owens Corning R-value where the cavities opened up. The homeowner got a dry, sealed attic instead of an R-value number stapled over a wet problem. That’s the difference between guessing and diagnosing, and it’s what Lawndale homeowners call us for.
Noel Camacho leads our crews, and he holds the team to one standard: the foam goes in right, or it doesn’t go in. We carry open-cell and closed-cell systems from Icynene and Demilec, so the recommendation is driven by your roof pitch, your sheathing condition, and how much marine-layer moisture your attic sees, not by whatever’s loaded on the truck. Eight manufacturer brands sit on our shelf, but we’ll only quote the one that fits your house.
Crawl Space Spray Foam Insulation in Lawndale
Crawl Space Spray Foam Insulation in Lawndale is a job we run most often on the small-footprint bungalows and low-rise apartment buildings where raised foundations sit over damp, tight-access dirt floors. Most of the crawl spaces under Lawndale’s older homes were never insulated when the houses went up, and the ones that were got fiberglass batts that have since sagged, soaked up ground moisture, or been shredded by rodents. Closed-cell Demilec sprayed against the subfloor and rim joists seals the assembly and keeps the damp marine-layer air from wicking up through the floor system. A typical Lawndale crawl space runs $1,800 to $4,200 depending on access and square footage.
Rim Joist Air Sealing
The rim joist is where the floor framing meets the foundation wall, and on Lawndale’s 1940s and 1950s builds it’s almost always a straight shot for outside air. We spray closed-cell foam into the rim cavities to cut the stack effect that pulls damp crawl space air up through the walls and into the living space.
Subfloor Underside Coating
For homes where the floor feels cold in the morning even with the heat on, a 1.5 to 2 inch layer of closed-cell foam under the subfloor stops the thermal bridging and adds a vapor barrier at the same time. It’s faster than pulling up floors and it works with the house as built, not against it.
Garage Spray Foam Insulation in Lawndale
Garage Spray Foam Insulation in Lawndale makes sense on the attached garages that sit under the low-slope roofs common to 90260 and 90261, where the garage ceiling shares a cavity with bedroom floors above. If the garage is attached and the ceiling is uninsulated, the room above it will never hold temperature, no matter what the attic has in it. We spray closed-cell foam across the garage ceiling and down the shared wall to break that thermal path. A single-car garage ceiling in Lawndale typically runs $1,200 to $2,600; a two-car with walls is closer to $3,000 to $5,000.
Attached Garage Ceiling Retrofit
The garage side of a shared wall is rarely framed with insulation in mind, so we foam the ceiling joist bays first and then the party wall top plate. That seals the air path that lets garage heat climb into the house all afternoon while the marine layer keeps the roof deck cool.
Party Wall Sound and Thermal Break
For attached garages that double as workshops or laundry rooms, open-cell Icynene on the shared wall cuts sound transfer and stops the garage from acting as an unconditioned heatsink against the house. It’s a two-problem fix in one pass.
Trusted Brands We Service in Lawndale
Our Spray Foam Insulation crews install Icynene open-cell and Demilec closed-cell systems, and we stock the full accessory line for both: nozzles, hoses, and the air-sealing tapes and can foam we need for top-plate and party-wall work. For Lawndale homeowners who want a fiberglass or mineral wool option instead, we carry Owens Corning and CertainTeed batt products, plus GreenFiber blown-in cellulose for walls and attic floors. We keep local stock for Lawndale jobs so a change order on a 90260 bungalow doesn’t mean waiting a week on a parts truck. Most jobs wrap in one or two days.
Common Spray Foam Insulation Problems We See in Lawndale Homes
- Fog-dampened sheathing under closed-cell foam. Lawndale’s inland-edge position means marine-layer fog rolls in most nights, and on shallow-pitch roofs that condensation settles on the sheathing. Closed-cell foam sprayed directly over damp decking traps that moisture against the wood and starts rot. We dry the deck and check for staining before any foam goes down.
- Rodent-compacted and sagging legacy batts left in place. On the 90260 side streets, we routinely pull out original rock wool or fiberglass batts that rodents have tunneled through. Spraying foam over compacted batts leaves voids and air paths behind the foam, so the R-value on the spec sheet never shows up in the house.
- Unsealed party walls and top plates on attached garages. Lawndale’s tight lots mean attached garages share framing with the living space, and those top-plate gaps are a straight air path. A single-pass foam job that misses them leaves the house leaky even with new attic foam.
- Irregular attic cavities over flat and shallow-pitch roofs. Low-slope roofs create wedge-shaped attic bays that a uniform foam pass can’t fill evenly. We shoot irregular cavities in stages and check thickness with a depth gauge, because a thin spot over a ceiling joist is a heat path in summer and a condensation point in winter.
Pricing for Spray Foam Insulation in Lawndale, CA
Spray foam insulation in Lawndale runs on square footage and foam type. Open-cell foam runs $2.50 to $4.00 per square foot installed and works well for interior walls and sound control. Closed-cell runs $4.50 to $6.50 per square foot, and we spec it for Lawndale’s damp attics and crawl spaces because it acts as its own vapor retarder. A full attic retrofit on an 800-square-foot 1950s bungalow in 90260 typically lands between $3,800 and $5,800. A crawl space runs $1,800 to $4,200. A garage ceiling is $1,200 to $2,600. The variable is access, sheathing condition, and how much legacy material has to come out first. Call (866) 605-6949 and we’ll give you a fixed quote before any work starts.

FAQs About Spray Foam Insulation in Lawndale
Yes, but only after the sheathing has been dried and the source of the moisture addressed. Lawndale’s marine layer dampens attic sheathing on most nights, and closed-cell foam sprayed over wet wood traps that moisture permanently. We dry the deck, fix any ventilation issues, and then foam. Call (866) 605-6949 to have us inspect your attic before you commit to a quote.
Lawndale’s housing stock is mostly 1940s to 1960s builds, and the attics in those homes have had decades for rats and mice to tunnel through the original batts. The damp coastal air makes the fiberglass sag faster than it would in a dry climate. We pull the old material and air-seal before any new foam goes in, so you’re not layering good insulation over a rodent problem.
It does, especially on the shallow-pitch and flat-roof attached garages where the garage ceiling shares a cavity with a bedroom or living space above. Closed-cell foam on the garage ceiling and party wall stops heat from climbing into the house and blocks the air path along the shared top plate. Expect to pay $1,200 to $2,600 for a single-car garage ceiling in Lawndale.
Closed-cell is the better default for Lawndale because it acts as its own vapor barrier and won’t absorb the marine-layer moisture that settles in attics and crawl spaces every night. Open-cell lets vapor through, which is fine on interior walls but risky against damp sheathing. We stock both Icynene open-cell and Demilec closed-cell and spec based on the actual assembly, not a blanket rule.
We do, and most of the Lawndale crawl spaces we see are tight, damp, and uninsulated. Closed-cell Demilec sprayed on the subfloor and rim joists seals the floor assembly and keeps ground moisture from wicking up into the house. Most Lawndale crawl space jobs run $1,800 to $4,200, and we’ll give you a firm number before we start.
