Lakewood’s postwar tract homes were built fast and tight to the ground. That means shallow crawl spaces, original fiberglass batts that have long since slumped into the dirt, and moisture problems that homeowners in pier-and-beam cities like Long Beach rarely deal with. We know exactly what we’re walking into when we arrive at a Lakewood home, because we’ve been through hundreds of these crawl spaces since 2011.
Key Takeaways:
- Full encapsulation in Lakewood: $4,000-$9,500, most jobs done in one day

Our Crawl Space Encapsulation & Vapor Barrier Services in Lakewood
Every Lakewood home has its own quirks, but the 1950-1953 construction era means we see the same failure patterns again and again. Here’s what we do about them.
Crawl Space Vapor Barrier
A vapor barrier in a Lakewood crawl space typically costs $1,200-$3,200 depending on access and square footage. Because so many Lakewood crawls sit under 18 inches of clearance, we use flexible 12-mil reinforced polyethylene that our technicians can maneuver into tight corners without tearing. The Del Amo Boulevard, Bellflower Boulevard, and Carson Street corridors all have homes with the same tight-clearance challenge, and we’ve dialed in the technique for it.
Crawl Space Encapsulation
Full encapsulation in Lakewood runs $4,000-$9,500 and includes sealing the ground with a heavy vapor barrier, sealing foundation vents and rim joists, insulating the perimeter walls, and often adding a dehumidifier sized for the space. The tight clearances in Lakewood’s slab-on-grade ranchers require low-profile materials and flexible sealing work that a generalist contractor typically won’t know how to execute. Our crew has done this enough times off Del Amo, South Street, and Woodruff Avenue that we can plan the job before we even arrive.
Crawl Space Insulation
The original fiberglass batts in Lakewood crawl spaces were installed in 1950 and have been absorbing humidity for over 70 years. They’ve compressed, slumped, and in many cases are hanging down like wet towels. We remove the degraded material and replace it with rigid foam board or closed-cell spray foam from brands like Icynene and Demilec, which won’t absorb moisture the way fiberglass does. For the perimeter walls of these shallow crawls, 2-inch foam board is often the right solution.
Crawl Space Moisture Control
Moisture control in Lakewood is a year-round issue, not just a rainy-season one. Winter irrigation and the occasional heavy storm saturate the soil under the home, while summer heat pulls that moisture up through the slab and into the house. We install dehumidifiers, vapor barriers, and drainage solutions sized for the specific conditions of each crawl. A compact dehumidifier in a 900-square-foot Lakewood ranch typically adds $800-$1,800 to a project depending on capacity.

Trusted Brands We Service in Lakewood
We install and service crawl space products from Owens Corning, Icynene, and Demilec, and we keep common materials stocked for Lakewood jobs so we’re not waiting on a warehouse shipment. If your existing vapor barrier was installed by another company and it’s failing, we’ll tell you honestly whether a repair makes sense or a full replacement is warranted. Most Lakewood crawl space jobs use Owens Corning 12-mil reinforced barrier material because it holds up to foot traffic in tight clearances better than thinner films.
Common Crawl Space Encapsulation & Vapor Barrier Problems We See in Lakewood Homes
- Sagging, waterlogged fiberglass batts. The original insulation in 1950s Lakewood homes has absorbed decades of humidity, lost its R-value, and is often hanging onto the ground. We remove it and start clean.
- Torn DIY vapor barriers. Shallow crawls mean anyone working down there is on hands and knees, and thin plastic rips within months. Seams separate and moisture wicks through. We see this constantly in the neighborhoods off Bellflower Boulevard.
- Rusted floor registers and furnace ducting. Trapped moisture rusts the metal components above the crawl. On a recent job off Del Amo Boulevard, our crew found a 1952 ranch with registers so rusted they crumbled when touched. Encapsulation stopped the moisture at the source.
- Persistent musty odor that returns after cleaning. If you’ve had your carpets cleaned and the smell came back in a month, it’s coming from the crawl. Sealing the ground and controlling humidity stops it permanently.

FAQs - Crawl Space Encapsulation & Vapor Barrier in Lakewood
Because the crawl spaces were never designed to stay dry. Lakewood’s tract homes were built on slab foundations with shallow perimeter crawl spaces, and 70 years of winter irrigation, rain, and ground moisture have saturated the soil underneath. Even in summer, moisture wicks up from that soil into the house. Encapsulation seals that pathway off.
Yes. It’s harder work, but it’s absolutely doable. We use flexible 12-mil reinforced material and install it in sections that our technicians can maneuver into 18-inch clearances without ripping or leaving unsealed seams. DIY attempts in these tight spaces almost always fail within months because thin plastic tears under foot traffic. Call (424) 622-5846 for an assessment.
A vapor barrier covers the ground. Full encapsulation also seals the rim joists, vents, and perimeter walls, creating a conditioned space that stops moisture from entering the home altogether. For Lakewood’s slab-on-grade ranchers with musty smells coming through floor registers, full encapsulation is usually the fix that actually works long-term.
Almost always, yes. The musty odor is mold and moisture in the crawl space rising through the duct system and floor registers. Sealing the ground and installing a dehumidifier eliminates the moisture source, and the smell goes away for good. We’ve had Lakewood homeowners on Del Amo and Woodruff comment that the smell was gone within 48 hours of the job finishing.
No. We handle the cleanout as part of the job. Debris, old insulation, and dead pests get removed and bagged, then we install the new barrier and sealing materials. Most cleanouts run $400-$1,200 depending on how much has accumulated in the crawl. Call (424) 622-5846 and a live person will walk you through what to expect.
