Why Walt’s Insulation Is Burbank’s Preferred Crawl Space Encapsulation & Vapor Barrier Company
We’ve been doing this work since 2000, and Burbank homeowners keep calling us back because we show up when we say we will and we don’t disappear after the check clears.

Our Crawl Space Encapsulation & Vapor Barrier Services in Burbank
Here’s what our Crawl Space Encapsulation & Vapor Barrier team handles for Burbank homes. Each job starts with a free inspection, a written estimate, and a straight answer about what you actually need.
Crawl Space Vapor Barrier
A vapor barrier is the first line of defense for Burbank’s raised foundations. We install 12-mil reinforced poly over the dirt floor, run it up the foundation walls, and seal every seam with tape that holds. On a 1,200 sq ft crawl space, expect $1,900-$3,400 depending on how much demolition and prep the space needs. In Burbank’s hard-packed clay yards, we also check for sprinkler run-off that’s been soaking the soil directly against the foundation.
Crawl Space Encapsulation
Full encapsulation means sealing the entire crawl space: vapor barrier on the floor and piers, rigid foam board over every foundation vent, closed-cell foam on the rim joists, and a dehumidifier if the space needs it. This is the fix for Burbank homes where the musty smell returns every summer no matter what you do. A full encapsulation on a typical 1950s ranch near Victory Boulevard runs $6,000-$11,500. The job takes one to two days, and you stay in the house the whole time.
Crawl Space Insulation
Most older Burbank crawl spaces have zero insulation anywhere. That means every summer night, humid valley air condenses on the cool floor joists, and every winter night, cold air bleeds up through your floors. We install closed-cell spray foam on rim joists and band boards, which seals the air leaks and insulates in one step. For Burbank’s flatland ranches, this is the single most effective upgrade for stopping that damp-crawlspace smell.
Crawl Space Moisture Control
Moisture control is more than laying plastic. In Burbank, the issue is often sprinkler overspray hitting the foundation, flat yards that don’t drain, and clay soil that holds water against the stem walls. We assess the grade around the house, check where the downspouts discharge, and measure the relative humidity in the crawl space before we recommend a solution. Sometimes a dehumidifier is necessary; sometimes regrading a section of yard fixes the problem. We’ll tell you which one you actually need, not just the expensive one.

Trusted Brands We Service in Burbank
We install products from manufacturers we know hold up in Burbank’s heat and moisture conditions. For crawl space work, that means reinforced vapor barriers rated for direct ground contact, closed-cell foam from Demilec and Icynene for rim joists where humidity swings are brutal, and Owens Corning rigid foam board for sealing foundation vents. We keep common materials stocked for Burbank jobs, so we’re not waiting on a truck from out of state when your crawl space is already torn open. Faster turnaround, fewer delays.
Common Crawl Space Encapsulation & Vapor Barrier Problems We See in Burbank Homes
- Crawl spaces under 1940s-1960s stucco ranches often have zero insulation and open vents. Humid valley air condenses on cool floor joists every summer night, which leads to sagging floors and mold growth inside the joist bays.
- Dirt-floored crawl spaces become a wicking layer after sprinkler run-off from Burbank’s flat, hard-packed yards. The subfloor stays damp even when the attic is bone-dry, and that’s when you start seeing cupping hardwood and peeling baseboards.
- Homeowners install a thin 6-mil poly sheet without sealing the foundation vents or lapping seams. That creates a balloon of moisture under the house: the barrier traps rising vapor but doesn’t stop ambient air infiltration, so the musty smell returns within a season.
- Older Burbank homes near Victory Boulevard and the Rancho area often have pier-and-beam crawl spaces with brick vent openings. These were designed for a climate nobody actually lives in anymore. The vents let in Burbank’s 100°F summer air and every ounce of humidity the valley can produce.
Pricing for Crawl Space Encapsulation & Vapor Barrier in Burbank, CA

What moves the price: crawl space height (some Burbank crawl spaces are only 18-24 inches, which slows the work), how much debris and old insulation needs removal, and whether your foundation vents are brick or concrete.

FAQs - Crawl Space Encapsulation & Vapor Barrier in Burbank
Because Burbank’s “dry” climate is only dry above ground. The valley floor sits on hard clay that holds irrigation water from your sprinklers and your neighbors’ sprinklers against your foundation walls year-round. That moisture wicks up through a dirt crawl space floor and into your subfloor, even when the air outside feels bone-dry. A vapor barrier stops that ground-to-joist moisture transfer, which is why it matters here as much as it does in Seattle. Call (408) 837-7384 to schedule a free inspection and we’ll show you the moisture readings from your own crawl space.
You can, but most DIY vent covers leak air and create the exact moisture balloon we described earlier. Proper vent sealing uses rigid foam board cut and fitted to each opening, then caulked or foamed in place. If you don’t also address the dirt floor and the rim joists, sealing vents alone just traps moisture. We offer a free second opinion on any written estimate, so you can see what a full job includes before you decide whether the DIY route is worth it.
One to two days for most Burbank bungalows in the 1,000-1,400 sq ft range. You don’t need to move out. Our crews work through the crawl space access, not through your living room. We lay floor protection from the entry to the crawl space access, and the only thing you’ll notice is the smell disappearing after we seal everything up. Call (408) 837-7384 to get a specific timeline for your home.
Both, but mostly less humid. When you stop ground moisture from wicking into the floor joists, your floor assembly dries out, and dry floors mean your AC doesn’t have to work as hard to remove latent heat from the air. Burbank summers push attics to 150°F, and any moisture under the house makes the cooling load worse. You’ll notice the musty smell goes first, then a more stable indoor temperature.
A 12-mil reinforced poly barrier, which is rated for direct ground contact and holds up against punctures from rocks and debris under Burbank’s older homes. We run it up the foundation walls and piers, not just across the floor, and we tape every seam. For pier-and-beam ranches near Victory Boulevard and the Rancho area, we also recommend closed-cell foam on the rim joists to seal air leaks at the same time. Call (408) 837-7384 for a free estimate, and ask about our $40 off any repair over $200 and 10% senior and veteran discount. We answer live, 24/7.
