Schedule Your Free Inspection (https://intercoastalcrawlspace.com/free-estimate) Warning signs ## Seven signs something is wrong below You do not have to crawl under the house to know something is off down there. A crawlspace problem shows up in the rest of the home first, usually as a smell. One sign is enough reason for a free look. Schedule Free Inspection: https://intercoastalcrawlspace.com/free-estimate - Standing water or damp soil under the home - A musty smell in the rooms above - Insulation sagging or lying on the ground - Cupped, springy, or cold floors - Condensation on ducts or pipes - Visible mold or dark staining on the subfloor - A humidity reading upstairs that will not come down What we do ## How we fix what is under your home Every service below is scoped to the actual problem, priced from the readings we take on site. ### Crawlspace Cleanouts We haul out debris, torn plastic, and fallen insulation. A clean space is the only way to find the moisture source. Learn moreabout crawlspace cleanouts (https://intercoastalcrawlspace.com/services/crawlspace-cleanout) ### Vapor Barrier Installation Bare Lowcountry soil pushes moisture up all year. A lapped and sealed barrier stops it at the source. Learn moreabout vapor barrier installation (https://intercoastalcrawlspace.com/services/vapor-barrier-installation) ### Crawlspace Encapsulation Full liner, sealed vents, and a controlled space. We recommend it when the moisture load calls for it. Learn moreabout crawlspace encapsulation (https://intercoastalcrawlspace.com/services/crawlspace-encapsulation) ### Insulation Removal Wet batts hold water against your subfloor and lose R-value. We remove them and replace once the space is dry.

We size the unit to the space and set the drain up right.

We read the crawlspace first and recommend second. Call (843) 408-3877 (+18434083877) > If your crawlspace only needs a vapor barrier, that is what we quote. We will not sell you an expensive and unnecessary encapsulation to solve a simple vapor barrier problem. How it works ## Inspect. Document. Fix. Three steps from the first call to a crawlspace that stays dry. ### Inspect. A technician goes all the way under the home, not just to the hatch. Ground cover, piers, subfloor, ducts, insulation, and vents all get looked at, with wood moisture and humidity readings taken as we go. ### Document. You get labeled photos and the actual numbers, so you can see what we saw without crawling under there yourself. Nothing gets described to you that is not also shown to you. ### Fix. We write a scope for the work the readings support, at a flat price. We say what is urgent, what can wait, and what needs nothing at all. Why it matters ## The air in your crawlspace does not stay down there A house breathes from the bottom up. Warm air rises and leaves through the top of the home, and the air that replaces it gets pulled up from below. In a vented crawlspace, that means the damp air under your floor ends up in the rooms you live in. That is why the first sign is usually a smell, not a puddle. It is also why a dehumidifier upstairs never fixes the problem. The moisture is coming from the ground, so the ground is where we start. Charleston makes it worse than most places. High water tables, long humid summers, and foundation vents at grade keep pulling wet air into a space that never gets a chance to dry.

A homeowner gets shown a few dark photos and a five-figure number for work nobody measured. We do it the other way around. The readings come first, and the scope follows the readings. Sometimes the honest answer is that your crawlspace needs one thing. Sometimes it is that it needs nothing at all. You will get that answer either way, in writing, with the photos to back it up.
