Condensation beading on the ductwork, a puddle that never quite dries, insulation hanging loose from the joists: a wet crawl space shows its hand in several places at once. Keeping that water in check is the whole point of crawl space moisture control, and Piedmont Pressure Seal handles it across Winston-Salem, NC, plus nearby communities like Mocksville, Lexington, and High Point. Finding the water comes before covering anything up.
Operating out of Winston-Salem, NC, Piedmont Pressure Seal LLC is a locally owned waterproofing and foundation contractor that has served the Piedmont Triad since 1989. For crawl space moisture control, it combines drainage corrections, sump systems, vapor barriers, vent sealing, and dehumidification to address standing water, ground evaporation, and humid air together. Crews from the company also encapsulate crawl spaces, waterproof basements, repair foundations, and install yard drainage.
A wet crawl space rarely has a single cause. Water seeps through the block after storms, vapor rises from the soil all year, humid air pours through the vents in July, and a slow plumbing drip adds to the pile without anyone noticing.
Triad geography sets the stage. Piedmont clay drains slowly, so rain lingers in the soil beside the foundation and works its way through block walls and footing joints. Grading that tilts toward the house, downspouts emptying at the corner, and vents open to August air all push more water into a space that already struggles to dry out.
Sorting it out means handling each source in turn. We map where water enters, correct the grading and downspouts feeding the problem, install drainage or a sump where water collects, cover the soil with a sealed liner, and add dehumidification for whatever humidity remains. Skipping a step leaves the others working harder than they should.
The payoff shows up in wood moisture readings that drop and stay down. Insulation quits falling, mold loses its footing, and the area under your house becomes somewhere you could send a technician without apologizing first.
Getting moisture under control down there protects more of your home than most people expect.
Joists, girders, and sill plates lose strength as moisture content climbs, and sustained dampness opens the door to rot and termites. Keeping wood in the dry range preserves the framing you walk on every day. Replacing rotted joists costs many times what prevention does.
Wet fiberglass compresses, loses its R-value, and eventually falls out of the joist bays entirely. Ducts sweat, drip onto the liner, and lose efficiency along the way. A dry space keeps both doing the job you paid for.
Air rises through a house, carrying whatever the crawl space holds into your kitchen and bedrooms. Controlling moisture cuts the mold spores, musty odors, and pests riding that current. Families dealing with allergies or asthma usually feel the difference.
Humid air takes more energy to cool, and damp insulation stops slowing heat transfer the way it should. Once the space dries out, your HVAC system can work the way it was designed to. Closed crawl space research conducted in North Carolina has documented measurable savings compared with traditional vented designs.
Crawl space moisture shows up fast during a home inspection and can stall a closing. Documented work tells a buyer somebody handled the issue properly. Even when selling is years away, that paperwork is worth keeping in a drawer.
Moisture control overlaps with the services below, and most homes need some combination of them.
Complete crawl space encapsulation ties the liner, sealed walls, closed vents, and humidity control into one system. It's the most thorough option we offer for homes that stay damp no matter the season.
Ground cover does the heavy lifting against soil evaporation, and crawl space vapor barrier installation puts a sealed liner across the dirt and up the piers. Most moisture control plans begin right here.
Air that stays humid after the water sources are handled calls for crawl space dehumidification. A properly sized unit holds the space in a safe range through the stickiest weeks of summer.
Expect the following from the first phone call to the final walkthrough.
Three and a half decades of crawl space work across Forsyth, Guilford, Davidson, and Davie counties has taught our team to read a space quickly. Justin Gornto, the owner, worked alongside that crew before taking the reins. All of it shows up in the first twenty minutes of the visit.
Moisture problems usually need drainage, a liner, and humidity control working together, and juggling three contractors gets old fast. Our crews handle the whole scope, so nothing falls through the gaps between trades. Scheduling stays simple too.
You'll get a written plan describing the work and the reasoning behind it, with options wherever options exist. Nobody here earns a commission, so there's no incentive to pad the job. Take whatever time you need to decide.

Membership in the Better Business Bureau, the National Association of Home Builders, and the National Federation of Independent Business keeps our work visible. Permits get handled by our office when a project calls for them, and emergency service is available upon request.
Sagging insulation, condensation on ducts or pipes, a musty smell upstairs, and rusting fasteners all point that direction. Wood reading above roughly 18 percent moisture sits in the range where fungus grows. An inspection with a moisture meter gives you a clear picture without guesswork.
Water after a big storm is common around here, though common and acceptable aren't the same thing. Soil that stays saturated keeps pumping vapor into the space and can undermine footings over time. Drainage corrections, a sump, or regrading usually solves it.
Closed, conditioned crawl spaces have been allowed here for years, and research conducted in the state found closed designs stayed drier than vented ones. Opening vents during humid weather often adds moisture rather than removing it. Sealing them works best alongside a ground cover and a dehumidifier.
Bare soil evaporating moisture, humid summer air entering through vents, groundwater pressing through block walls, and plumbing leaks are the four main sources. Piedmont clay holds rainwater against foundations long after storms pass, which keeps that supply steady. Roof runoff and the grade around the home play a supporting role too.
Removing the moisture stops mold from spreading and keeps new growth from taking hold, since colonies can't survive without it. Existing growth still needs proper remediation, which is separate work with its own protocols. We'll flag whatever we find and point you toward the right specialist when the situation calls for one.
