Interior Walls Waterproofing in Dover, NH
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.

Crawl Space Encapsulation in Dover
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. Water heaters and boilers run long hours through winter, which shortens their service life compared to milder climates. An encapsulated crawl space can noticeably 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.

We use durable materials and efficient techniques to provide lasting protection, reducing the chance of future repairs. Our goal is to deliver value and confidence.
Shower Wall Waterproofing in Dover
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 attention before new tile is set.
Plumbing Leak Behind Walls in Dover
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 surfaces.
Shower Pan Leak Repair and Waterproofing in Dover, NH
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.
Laundry Room and Utility Wall Waterproofing in Dover, NH
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 prevent costly drywall repairs.

Basement Wall Sealing in Dover, NH
Basement wall sealing is a critical part of walls waterproofing. Water heaters and boilers work hard through winter, which shortens their service life compared to milder climates. 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, healthier environment in your Dover, NH basement.

Frequently Asked Questions About Walls Waterproofing in Dover
The cost of walls waterproofing in Dover, NH 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 transparent, itemized quotes after a thorough inspection.
Shower remodels that change plumbing or drain locations often require a permit. Simple membrane replacement may not. We check local requirements and obtain permits when needed.
Yes. Sealing a wall with an active leak behind it traps water and causes more damage. We always fix the leak and dry the cavity first.
Walls waterproofing is a primary 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.
Interior waterproofing addresses water after it has entered the foundation, typically managing it with sealants and drainage systems inside the basement or crawl space. Exterior waterproofing prevents water from reaching the foundation walls in the first place, usually by excavating and applying membranes or coatings to the outside of the foundation.
Yes, FVR Plumbing stands behind the quality of our walls waterproofing services. We offer comprehensive warranties on our materials and workmanship, giving you peace of mind. Warranty details will be provided with your project proposal, spelling out the coverage and duration of your waterproofing system.
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.
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.
