A wet basement can ruin stored keepsakes, invite mold, and turn perfectly good square footage into a space you'd rather avoid. Piedmont Pressure Seal provides basement waterproofing in Winston-Salem, NC, and nearby areas, stopping leaks and seepage so your lower level stays dry season after season. We'll figure out why water's getting in and recommend a fix that suits your home, and you'll never get a hard sell from our team.
Piedmont Pressure Seal is a locally owned waterproofing contractor based in Winston-Salem, NC, that has served homeowners throughout the Piedmont Triad since 1989. Our company offers basement waterproofing that includes interior and exterior systems, leak and seepage repair, sump pump installation, and basement moisture control. Our exterior work often features Delta®-MS membranes from Dörken Systems Inc., which come with the Delta®-MS Dry Foundation Guarantee.
Basement moisture rarely announces itself with a flood. More often, it shows up as a clammy feel in the air, a faint mildew odor, rust on the washer legs, or cardboard boxes that soften and sag after a few months on the floor.
Most of that dampness starts outside. Rainwater soaks into the clay soil around your foundation, and once the ground is saturated, it pushes moisture through porous concrete and tiny cracks. Humid summer air condenses on cool basement surfaces, much like the beads of water on a glass of sweet tea.
Fixing it starts with tracking down every entry point. We check the walls, floor, grading, and gutters, then put together a plan that may include sealing cracks, adding interior drainage and a sump pump, installing an exterior membrane, or running a dehumidifier to tame the humidity. Many basements need a mix of these methods, and we'll explain each one before any digging or drilling begins.
With the right fixes in place, your basement can weather even the rainiest Winston-Salem spring. The air smells fresher, your belongings stay safe, and that extra square footage finally becomes space you can enjoy as a workshop, guest room, or movie night hangout.
Water can enter a basement from several directions, so each waterproofing service we offer targets a different weak spot.
Even without active leaks, high humidity can make a basement feel damp and encourage mildew growth. Our moisture control solutions pair dehumidification with sealing and drainage improvements to bring humidity down to a healthy range.
Some homes need protection from the outside in, while others do best with an interior system that manages water after it enters the home. For exterior jobs, we excavate to the footing and apply a Delta®-MS membrane to provide strong basement wall waterproofing from the soil side. Inside, a drainage channel along the base of the walls routes water to a sump pit before it spreads across the floor.
Seepage through cracks, pipe openings, and the seam where the walls meet the floor is one of the most common problems we see in Triad basements. After sealing those entry points, we add basement floor waterproofing whenever water pushes up through the slab. Tackling leaks early stops a small drip before it becomes a big mess.
Waterproofing basement spaces the right way the first time spares you from repeat repairs and patchy quick fixes. Every system we design accounts for your home's soil, grading, and drainage so it keeps working for decades. Our Delta®-MS installations even come with a lifetime warranty for added reassurance.
During heavy storms, a sump pump removes water that collects in your basement, keeping it away from the foundation. We install new pumps, replace worn-out units, and set up backup systems so a power outage or pump failure won't leave you stranded. Regular testing keeps the whole setup ready when you need it most.
Good prevention starts outside the basement, which is why we inspect your gutters, downspouts, and yard grading at every visit. Redirecting runoff and sealing vulnerable spots keep groundwater from building up against the foundation in the first place. It's a simple step that helps every other part of your system work better.
Cold floors in winter and sticky air in summer often trace back to a crawl space that's letting in too much moisture. We handle crawl space encapsulation by sealing the ground and walls with a thick vapor barrier, then managing humidity to keep mold, wood rot, and bugs at bay.
If you've spotted gaps around your windows or a floor that seems a bit uneven, your foundation may be shifting. Our foundation repair team pinpoints the cause of the movement, then corrects settlement and structural issues using methods designed to stabilize your home.
Pooling water in the yard or around the foundation is a clear sign your property needs a better way to shed rain. Through our drainage installation services, we design and build systems such as French drains, underground downspout lines, and yard drains that move water off your property.
Backed-up drains always seem to happen at the worst possible moment. Our drain cleaning service removes debris and sediment that clog your lines, restoring normal flow. Regular maintenance visits help stop repeat clogs before they start.
Every time it rains, wet soil pushes water against your foundation with surprising force. Our exterior waterproofing process relieves that pressure by excavating, installing a Delta®-MS membrane from Dörken Systems Inc., and adding drainage along the footing.
A sump pump works quietly in the background until the day you really need it. We specialize in interior waterproofing and sump pumps, installing perimeter drains, upgrading worn-out pumps, and adding backup systems for stormy nights. If water has already made a mess, we'll pump it out and help you get back on track.
Cracks show up in foundations for all sorts of reasons, from soil movement to normal concrete curing. Our foundation crack repair solutions address wall cracks, damaged concrete, and bowing walls with sealing and carbon fiber reinforcement that hold up over time.
Solving a water problem doesn't always require a full-scale drainage system. Our small drainage projects focus on targeted improvements such as rerouting downspouts, addressing surface runoff, and grading small areas to ensure water flows away from your house.
Condensation on pipes, peeling paint, or a stubborn mildew smell can all mean moisture is building up somewhere in your home. With our water and moisture management approach, we evaluate your basement and crawl space together and then recommend solutions to reduce humidity, prevent water intrusion, and prevent mold.

It depends on the size of the job. Exterior work involving major excavation, new drainage connections, or structural repairs may require a permit, while many smaller interior projects don't. A reputable waterproofing company will check with the Winston-Salem/Forsyth County inspections office and handle the paperwork for you.
Plan on one to three days for most interior basement waterproofing projects, depending on the basement size and the system being installed. Exterior waterproofing usually takes longer because crews have to excavate around the foundation, apply a membrane, and backfill. Rainy stretches can also push the timeline back, since wet ground slows down outdoor digging.
Exterior waterproofing prevents water from ever reaching your foundation walls, making it the most thorough option for many North Carolina homes. When digging outside isn't practical, an interior system can catch water that has already entered and direct it to a sump pump. The right choice depends on your home's layout, soil, and budget.
The red clay soil around Winston-Salem homes holds water like a sponge after storms, building pressure against foundation walls until moisture pushes through cracks and joints. Clogged gutters, short downspouts, and yards that slope toward the house make things worse. Over time, even tiny gaps can turn into steady leaks.
North Carolina's humid climate and frequent heavy rains put basements at constant risk of leaks, mold, and moisture damage. Waterproofing protects your foundation, keeps your belongings safe, and helps preserve your home's value. It can also turn a damp, unused basement into a space you'll actually enjoy.
