Plumbing Leak Behind Walls in Camden
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We find 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.

Crawl Space Vapor Barriers in Camden
Many homes in Camden have crawl spaces, which are very prone to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting stops ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an effective way to control humidity and prevent wood rot.
Basement Wall Sealing in Camden, NJ
Basement wall sealing is a critical part of walls waterproofing. Hot, humid summers and cold winters put New Jersey plumbing through wide seasonal swings that stress joints, valves and water heaters alike. 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 Camden, NJ basement.
Commercial Wall Waterproofing in Camden
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 discovered.
Laundry Room and Utility Wall Waterproofing in Camden, NJ
Washing machine hoses, utility sinks and water heaters can all leak into nearby walls. We replace burst-prone rubber hoses with braided stainless hoses and install leak pans and shutoff valves. Walls around water heaters and laundry boxes can be sealed to resist water damage. These small upgrades head off costly drywall repairs.
Shower Wall Waterproofing in Camden
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.
Waterproofing for Older Homes in Camden, NJ
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Newer construction around Camden typically uses copper or PEX supply lines with PVC drains, which are easier to repair and update when needed. 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 Camden, NJ
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 clearly.

Frequently Asked Questions About Walls Waterproofing in Camden
The cost of walls waterproofing in Camden, NJ can vary significantly based on the method used, the extent of the damage, and the size of your foundation. Basic crack sealing might range from $300 to $800 per crack, while a full exterior foundation waterproofing project could be $8,000 to $20,000 or more. Interior drainage systems with a sump pump typically fall between $4,000 and $12,000. We provide clear, itemized quotes after a thorough inspection.
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.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the critical importance of a sound foundation. It often involves heavy excavation, specialized equipment, precise material application, and knowledge of drainage principles and local building codes. Improper waterproofing can lead to more severe and costly damage down the line, so professional help is the smart choice.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Camden may be required. Simple crack repairs typically do not need a permit. GLN Plumbing will help you determine if a permit is necessary for your project and assist with the application process if needed.
While minor DIY fixes like patching small cracks are possible, full 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.
Walls waterproofing is a key step in preventing future mold growth by eliminating the moisture source. However, it does not remove existing mold. If mold is already present, it will need to be professionally remediated before or along with the waterproofing process. Once the area is dry and mold-free, waterproofing will help keep it that way.
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 several days.
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.
