Plumbing Leak Behind Walls in Cary
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.
Waterproofing Costs vs. Repeat Water Damage in Cary, NC
Waterproofing a shower or wall costs far 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 Pan Leak Repair and Waterproofing in Cary, NC
A cracked or poorly sloped shower pan often causes wet baseboards and stained ceilings below. We test the pan by plugging the drain and flooding it to confirm the leak. Then we rebuild the pan with correct pre-slope, a new liner or bonded membrane and a properly clamped drain. A second flood test confirms the pan is watertight before tile.
Shower Wall Waterproofing in Cary
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.
Sump Pump Installation and Repair in Cary, NC
Sump pumps are a key 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 heavy storms. 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 correctly so water does not circulate back toward the foundation.

Crawl Space Encapsulation in Cary
Crawl space encapsulation involves sealing the crawl space entirely with heavy-duty vapor barriers and often includes a dehumidifier. This not only waterproofs the walls but also controls humidity, stopping mold growth and wood rot in the crawl space. High humidity can rust exposed metal pipe and fittings under homes, so crawlspace plumbing deserves a regular look. An encapsulated crawl space can significantly improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use durable, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.

Frequently Asked Questions About Walls Waterproofing in Cary
The cost of walls waterproofing in Cary, NC 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 usually fall between $4,000 and $12,000. We provide clear, itemized quotes after a thorough inspection.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Cary may be required. Simple crack repairs typically do not need a permit. HFN Plumbing will help you determine if a permit is necessary for your project and assist with the application process if needed.
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 make sure it stays that way.
Look for bubbling paint, soft drywall, stained baseboards and musty odors. White crust on block or stucco walls is another sign of moisture moving through. Loose tiles or cracked grout in a shower also mean water is getting behind.
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 warning signs, as they often point to ongoing water intrusion.
When professionally installed using high-quality materials, walls waterproofing can last for decades, often 20 to 50 years or even longer. The lifespan depends on the materials used, the quality of installation, and environmental factors like soil movement and water exposure. Modern membranes and sealants are designed for long-term durability.
A shower wall waterproofing project typically 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.
We commonly install Schluter Kerdi, Custom RedGard, Laticrete Hydro Ban and similar systems. The right choice depends on your shower design and tile. We follow each manufacturer's installation steps to keep the warranty in force.
