Nobody enjoys hauling soggy boxes out of the basement after a storm. From interior and exterior systems to leak and seepage fixes and sump pumps, our basement waterproofing solutions are built for long-term protection. After more than 35 years of keeping Triad basements dry, we've learned how to match the right fix to your home and your budget.
A damp, earthy smell drifting up through your floors usually starts right below your feet. With crawl space encapsulation, we seal the area with a durable vapor barrier that reduces moisture and humidity, helping keep mold and pests away and improving the air you breathe upstairs.
Sticking doors, sloping floors, and fresh cracks can all point to trouble with the ground your home sits on. We start every foundation repair with a thorough inspection, then handle structural and settlement-related fixes, tackle water intrusion, and bring in an engineer when a project calls for one.
Rainwater always takes the path of least resistance, and sometimes that path leads straight to your foundation. Our team handles all kinds of drainage installation projects, including French drains, exterior drainage systems, and downspout lines that carry water safely away from your house.
Got a drain that gurgles, backs up, or takes forever to empty? We clear clogged lines, track down the causes of recurring backups, and offer residential drain cleaning and preventive maintenance to keep things flowing. Addressing small clogs now can save your drainage system from bigger trouble down the road.
Stopping water before it ever touches your walls is our favorite way to keep a basement dry. For exterior waterproofing, we excavate around your foundation and install the Delta®-MS membrane from Dörken Systems Inc., often paired with GMX products and exterior drainage.
When water gets inside, a good interior system gives it somewhere to go other than your floor. Our approach to interior waterproofing and sump pumps covers interior drainage, sump pump installation and replacement, and backup pump systems for extra peace of mind. If you've already got standing water, we'll remove it and get your basement back to normal.
Here in the Triad, shifting clay soil and seasonal freeze-thaw cycles can leave cracks in even well-built foundations. Our foundation crack repair covers everything from hairline wall cracks to bowing basement walls, using sealing and carbon fiber stabilization from the inside or outside.
That soggy corner of the yard or puddle by the back steps might only need a simple fix. We gladly take on small drainage projects, such as extending downspouts, improving surface drainage, and redirecting runoff away from your home.
Excess humidity can quietly cause musty odors, mold, and wood damage long before you ever spot a leak. Through water and moisture management, we look at your whole home, from the basement to the crawl space, and put together solutions that reduce humidity and prevent moisture buildup.
We serve homeowners throughout Winston-Salem, Greensboro, High Point, Kernersville, Thomasville, and many surrounding communities.
Our basement waterproofing services tackle leaks and seepage at their source, whether that means an exterior membrane system, interior drainage paired with a sump pump, or a combination of both. After more than three decades of working in Winston-Salem's red clay soil, we know how water moves around local foundations and which solutions keep it out over the long run. The result is a dry, usable basement and the peace of mind that comes with lasting protection.
Humid North Carolina summers can turn an open crawl space into a damp, musty mess that invites mold, wood rot, and pests. With crawl space encapsulation, we install a durable vapor barrier to control moisture and humidity, protecting your home's structure and improving the air your family breathes upstairs. Many homeowners also enjoy a boost in energy efficiency once the job's complete.
Cracks, sloping floors, and sticking doors often signal a foundation that's settling or taking on water. Every foundation repair project we take on begins with a thorough inspection, and when a job calls for it, we work alongside engineers to design repairs that address structural damage, settlement, and water intrusion. That careful approach helps stabilize your home for years to come.
We combine decades of local experience, established products, industry connections, and customer-focused service to help homeowners address water and foundation concerns.
Since opening our doors in 1989, our hometown crew has earned a reputation throughout the Triad for top-tier waterproofing, quality workmanship, and genuine care for every customer.

Yes, because mold needs moisture to grow, and waterproofing cuts off the water that feeds it in basements, crawl spaces, and foundation walls. In North Carolina's humid climate, pairing waterproofing with humidity control gives you the strongest defense. When mold has already taken hold, have a qualified professional remove it before sealing up the space.
Your home usually drops hints, like musty smells, damp spots on basement walls, puddles after heavy rain, or white chalky deposits called efflorescence on concrete. Foundation cracks, a soggy crawl space, and rising indoor humidity can also point to water issues. A professional inspection can pinpoint where the water gets in and which fix makes the most sense.
A waterproofing service keeps groundwater and rainwater out of your home's lower levels by sealing the foundation, installing drainage systems, and managing moisture in basements and crawl spaces. Around Winston-Salem, that work often includes exterior membranes, interior drains with sump pumps, crawl space encapsulation, foundation crack repair, and yard drainage improvements. The goal is to stop water at its entry points so your home stays dry and structurally sound.
Many Winston-Salem homeowners schedule exterior waterproofing for late summer or early fall, when excavation tends to go smoothly, and the work wraps up before winter's freeze-thaw season arrives. Interior waterproofing and crawl space projects can happen any time of year, rain or shine. If water is already getting in, though, waiting for the perfect season only gives the damage more time to spread.
Winston-Salem's Piedmont clay swells when it's wet and can remain saturated for days after heavy rain, exerting steady pressure on foundation walls. Humid summers, pop-up thunderstorms, and leftover rain from tropical systems only add to the moisture load around local basements and crawl spaces. Waterproofing helps protect your home's foundation, air quality, and value from that ongoing exposure.
