Damp, musty air under the house or a floor that feels clammy? We cover the soil so less ground moisture rises into your home.
A crawl space vapor barrier in North Charleston is a sheet our crew lays over the bare dirt under your house, so the soil stops giving off moisture into the space below your floors.
Usually it starts with a musty smell, a floor that feels cold and clammy, or a look under the house that turns up bare dirt or a torn sheet someone put down years ago. The price turns on the size of the crawl space in square feet, how much room there is to work, how many piers and pipes the cover has to fit around, any old material we have to pull out first, and whether you want the soil covered alone or the whole crawl space closed off. The schedule turns on how easy it is to get in and what we find once we're under there. When I come out, I write the estimate step by step so you can see what goes where.
I come out to look at every job, go under the house myself and write the estimate. Our installers do the work with me or a lead installer on site, so someone who saw your crawl space before the job is there while the cover goes down.
I spent years as an HVAC service tech working on equipment in crawl spaces and attics, and the bigger problem was usually the leaks and damp around it. I started this business in 2023 to fix that side properly, one step at a time and in the right order.
We're licensed and fully insured. South Carolina's licensing board treats a contractor doing specialty trade work for a homeowner on a job over $500 as a residential specialty contractor, so it's fair to ask any installer how that rule applies to the job they're quoting.
If your crawl space is dry and the cover you have is still doing its job, I'll say so instead of selling you work your house won't use. Satisfaction guaranteed. When you're ready, call (843) 278-0240 or send the form below.
We reply to every call and form within one business day to set a time, and then I come out, go under the house, measure and write you a free on-site estimate with no pressure and no obligation. Have your address and a rough size of the crawl space in square feet handy, since that's how this work is priced.
In North Charleston, the city's Building Department issues building permits for renovations and residential work, and city rules require proper permits before anyone alters or moves a structure. Altering, digging around or moving a structure without a permit counts as a misdemeanor under those rules, so it isn't something to guess at. We find out which office covers your address, check what it asks for and take care of any permit your job needs before we start. If you'd like to ask yourself, the city's permit office takes questions at 843-740-2562, 2564 and 2569.
We're based in North Charleston and work across the cities around it, including Hanahan and Goose Creek. Most of our calls come from homeowners in older houses, where we often find vented crawl spaces with bare dirt or a worn-out sheet, low clearance and ductwork running through. If your city isn't listed, call and ask.
It covers the bare soil under your house, which can almost completely shut off one of the biggest sources of moisture in a home. That helps keep the floor framing from breaking down when it's damp, and it keeps moisture from working up through the walls into your rooms.
In humid climates, the air outside is often wetter than the air already in the crawl space, so letting more of it in can add the very moisture a barrier is there to stop. Over time that damp air can lead to problems with the structure, mold and pests. It's why I ask about your vents when I look at your crawl space.
Weigh what each does for your house against what each costs, because the research favors closing the crawl space when you can. Building America research on crawl spaces closed to outside air found they used less heating and cooling energy and cut humidity by more than 20%. Those results come from closed crawl spaces, not from a soil cover alone, so I put both side by side on your estimate.
Across the US, crawl space encapsulation usually costs about $3 to $10 per square foot, so the size of your crawl space matters most. That's a national range for the fuller job, not our price, and a soil cover alone usually lands lower. I give you your own figure after I've measured and looked at what's under there.
Set a regular time to have the crawl space and its barrier looked at, because upkeep under a house is easy to put off. Crawl spaces are usually tight, dark and hard to get into, so nobody checks them until something smells wrong. A torn seam or a new plumbing drip is much easier to deal with when it's caught early.
