Commercial Wall Waterproofing in Winston-Salem

We also repair the plumbing behind those walls when leaks are found.

Below-Grade and Basement Wall Waterproofing in Winston-Salem
Homes built from the late 1970s into the mid 1990s may still have polybutylene pipe, which is known for sudden failures. Wherever a home has a basement or below-grade walls, heavy rain and snowmelt can push water through foundation walls and cracks. We seal cracks with injection products, apply interior or exterior waterproofing and install drainage where needed. A sump pump may be added if groundwater collects.
Plumbing Leak Behind Walls in Winston-Salem
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We locate the leak with moisture meters, thermal imaging and pressure tests. The damaged section of pipe or valve is replaced, and wet drywall is cut out and dried. Once the cavity is dry, we restore the wall and seal any wet-area walls.
Commercial Walls Waterproofing in Winston-Salem
Beyond residential properties, HFN Plumbing also offers walls waterproofing services for commercial buildings in Winston-Salem. Protecting commercial basements, equipment rooms, and underground parking garages from water damage is essential to business operations. We understand the need for minimal disruption and efficient project completion for commercial clients. Our team works with property managers and business owners to install robust waterproofing solutions that fit the demands of commercial structures and their code requirements.
Crawl Space Vapor Barriers in Winston-Salem
Many homes in Winston-Salem have crawl spaces, which are highly susceptible to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting prevents ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an affordable way to control humidity and prevent wood rot.
Sump Pump Installation and Repair in Winston-Salem, NC
Sump pumps are a critical part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during flash floods. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed properly so water does not circulate back toward the foundation.
Shower Wall Waterproofing in Winston-Salem
Tile and grout are not waterproof on their own, so water reaches the backer board in every shower. If the walls were built without a proper membrane, moisture soaks into studs and drywall. We remove failing tile, install cement board or foam board and apply a membrane such as Schluter Kerdi, RedGard or Hydro Ban. Seams, corners and niches get extra reinforcement before new tile is set.

Interior Walls Waterproofing in Winston-Salem, NC
Interior walls waterproofing focuses on managing water that has already passed through the foundation walls. This usually involves installing an interior drainage system, often called a French drain, along the perimeter of the basement floor. Water is collected and channeled to a sump pump, which then sends it safely away from the foundation. While not preventing water from entering the wall, it stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and works well where exterior access is limited.

Absolutely. By preventing water intrusion through your walls, waterproofing greatly reduces the moisture and humidity levels in your basement or crawl space. This creates an environment less conducive to mold and mildew growth, improving air quality and protecting your belongings from moisture damage.

Yes, HFN Plumbing stands behind the quality of our walls waterproofing services. We offer full warranties on our materials and workmanship, giving you peace of mind. Warranty details will be provided with your project proposal, outlining the coverage and duration of your waterproofing system.
While minor DIY fixes like patching small cracks are possible, complete walls waterproofing is best left to professionals. It involves specialized knowledge of drainage, foundation mechanics, and proper material application. Improper DIY work can lead to poor results, wasted money, and worse water damage over time.
A shower wall waterproofing project usually takes two to four days, including drying time between coats. Exterior block sealing can often be completed in a day. Larger foundation jobs may take a few days.
The duration of a walls waterproofing project varies depending on its scope. Minor crack repairs might take a few hours, while an interior drainage system could take 1 to 3 days. A full exterior foundation waterproofing project, involving excavation around the entire home, could take 3 to 7 days or more. We provide a clear timeline during our first consultation.
Key signs you need walls waterproofing include damp or wet basement walls, visible mold or mildew growth, a musty odor in your basement or crawl space, efflorescence on concrete walls, cracks in the foundation, or standing water after heavy rains. Don't ignore these indicators, as they often point to ongoing water intrusion.
