Musty smell, bare dirt or a torn old sheet under the house? We deal with any water problem first, then cover the ground.
A crawl space vapor barrier is a plastic sheet laid over the bare dirt under your house. In Redondo Beach we put one in to help hold back the ground moisture and soil gases that rise into the space and up toward your floors.
Most people who call me have a musty smell they can't place, cold floors, or a crawl space nobody's been down in since they bought the house. The price mostly turns on how much ground there is to cover, which sheet you pick and what has to be fixed or cleared before it goes down, and the schedule turns on that same work plus any permit the city asks for. If the floors over the space feel cold too, crawl space insulation is worth talking about on the same visit, and you'll see what your job needs in the written plan from the estimate.
I do every estimate myself, and I'd rather you see what's under your house than take my word for it. If you've never been down there, I'll show you the dirt, the pipes and any wet spots, and explain what each one means for your house.
I grew up on a farm where you fixed what was actually broken and nothing more. If a patched pipe and a new sheet will keep your crawl space dry, that's what I'll tell you, even when a bigger job was on the table.
I learned insulation working on other crews before I started this business in Redondo Beach in 2023. Our crew does the installs, and I come out on site to check the work before we call a job done.
We're licensed and fully insured. Every job is backed by our satisfaction guarantee. When you're ready, call (424) 254-3847 or send the form, and tell us whether your crawl space has vents, any standing water, leaks or mold you've seen, and what's stored down there.
We reply within one business day to set up a free estimate at your house, with no obligation. I'll come walk the house with you, then leave you with photos of what we found and a written plan that shows what comes first and why.
Permits in Redondo Beach go through the city's Building and Safety office, and applications are done through the city's permit portal. The city doesn't take its paper application anymore, so if you've got an old printed form in a drawer, it's out of date. Whether your vapor barrier job needs a permit is something I look up for your address, and I'll tell you at the estimate what I found. When a job does call for one, we handle the application as part of the job.
A lot of the crawl spaces we go into around here haven't been looked at in years, with an old torn sheet or none at all and boxes or leftover lumber shoved into a corner. We're based in Redondo Beach and do the same work across the South Bay, in Torrance, Hermosa Beach, Manhattan Beach, Gardena and other cities nearby.
No, a vapor barrier only blocks moisture coming up from the ground, so it won't stop a leaking pipe or rainwater running under the house. One barrier maker says those need other waterproofing on top of the barrier, which is why the water fix goes first in our plan.
Find out whether your crawl space is vented or unvented, because the work is different for each and you'll want to know before you compare quotes. Federal guidance, which calls this sheet a vapor retarder, has the seams and the openings around pipes sealed with a durable sealant in unvented crawl spaces only. If you're not sure which you have, I'll tell you at the estimate.
A thin 6-mil contractor-grade sheet lasts about 3 to 5 years and a 20-mil reinforced barrier lasts 25 years or more, by one cost guide's estimate. Mil is thickness, a thousandth of an inch, so the heavier sheet is a lot tougher. It costs more at the start, so you're weighing that against replacing the thin one several times over.
It can help, though it reduces radon rather than removing it. The same federal guidance says a well-installed barrier helps to minimize ground moisture vapor and soil gases such as radon. How well it's put in matters, which is part of why we cover as much ground as we can reach.
Clear out what you can, because the sheet should cover all of the crawl space ground, or as close to all of it as is reasonably possible. One barrier maker also advises drying the space out first by removing standing water, wet insulation and debris, and considering professional remediation if there's mold. If you'd rather not crawl in, our crew handles the clearing as part of the job.
There's no single price, because the cost comes from your crawl space and not a chart. A heavier reinforced sheet costs more than thin plastic, sealing the seams in an unvented space adds work, and a leak, an old torn sheet or a lot of stored stuff all add to the job. Call (424) 254-3847 and I'll come look before you decide anything.
