Basement Wall Sealing in Gastonia, NC
Basement wall sealing is a key part of walls waterproofing. Mountain areas see much colder winters than the coast, so plumbing needs differ quite a bit from one end of the state to the other. We apply high-quality sealants to porous concrete and masonry walls to prevent moisture from wicking through and causing dampness, mold, or musty odors. This service can be performed alone or as part of a larger waterproofing system, offering a drier and healthier environment in your Gastonia, NC basement.

Sump Pump Installation and Repair in Gastonia, 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.
Commercial Wall Waterproofing in Gastonia
Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure. We waterproof commercial showers, mop sink walls and restroom wet walls with durable membranes. Work can be scheduled after hours to reduce downtime. We also repair the plumbing behind those walls when leaks are found.
Drainage System Integration in Gastonia, NC
Lasting walls waterproofing often requires a robust drainage system to divert water away from your foundation. This can include interior perimeter drains that channel water to a sump pump, or exterior French drains that collect surface water. Our team designs and installs custom drainage solutions for Gastonia, NC properties, so water is managed well and moved away from your home's vulnerable areas.
Foundation Crack Repair & Sealing in Gastonia
Even minor cracks in foundation walls can allow significant water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points permanently. This method fills the entire depth of the crack, restoring strength and preventing water penetration. We address both vertical and horizontal cracks, knowing that horizontal cracks can signal structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and costly future repairs.
Waterproofing for Older Homes in Gastonia, NC
Older homes, especially those built before modern waterproofing standards, are especially prone to water intrusion. Much of the housing in North Carolina was built after the 1970s, and many of those homes use CPVC, copper or PEX supply lines. Many older foundations may lack adequate exterior drainage or proper sealing. We specialize in assessing and upgrading waterproofing systems for these properties, often combining exterior excavation with interior drainage solutions. We take care to respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.
Waterproofing Costs vs. Repeat Water Damage in Gastonia, NC
Waterproofing a shower or wall costs much less than repeated drywall, cabinet and flooring repairs. Ignoring moisture also invites mold, which can be expensive to remediate. A typical shower wall waterproofing project falls in the low thousands, while exterior block sealing varies with wall size. We give you a written quote so you can compare options side by side.

Shower Wall Waterproofing in Gastonia
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.
