Shower Pan Leak Repair and Waterproofing in Lebanon, 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 verify 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 proves the pan is watertight before tile.

Foundation Crack Repair in Lebanon
Even small cracks in your foundation walls can allow water to seep into your basement or crawl space. Our walls waterproofing service includes foundation crack repair using specialized epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks promptly in Lebanon homes is important to avoid larger, more costly structural issues.
Crawl Space Encapsulation in Lebanon
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 significantly improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use tough, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.
Interior Walls Waterproofing in Lebanon, 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.
Laundry Room and Utility Wall Waterproofing in Lebanon, 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.
Exterior Foundation Waterproofing in Lebanon
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most reliable method for preventing water from entering the basement or crawl space. We use high-quality asphalt-modified polyurethane membranes or polymer-based coatings that resist hydrostatic pressure and soil movement. Most homes have basements, so foundation drainage and sump systems matter for keeping the lower level dry. Proper drainage solutions, such as French drains, are also added to divert water away.
Basement Wall Sealing in Lebanon, NH
Basement wall sealing is a critical part of walls waterproofing. Water heaters and boilers run long hours 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 Lebanon, NH basement.

Exterior Block Wall Waterproofing in Lebanon, NH
Block and stem walls often show efflorescence, which is the white mineral crust left when water passes through masonry. Irrigation and sprinklers aimed at the house are common culprits. We adjust or reroute irrigation, clean the wall and apply a breathable masonry sealer or elastomeric coating. Proper grading and drip line placement help keep the wall dry.

Frequently Asked Questions About Walls Waterproofing in Lebanon
The cost of walls waterproofing in Lebanon, 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 usually fall between $4,000 and $12,000. We provide transparent, itemized quotes after a thorough inspection.
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.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Lebanon may be required. Simple crack repairs typically do not need a permit. FVR Plumbing will help you determine if a permit is necessary for your project and assist with the application process if needed.
FVR Plumbing works with reputable manufacturers known for high-quality waterproofing products. We commonly use products from brands like Xypex, Tremco, and Sika for their proven effectiveness and durability, from crystalline admixtures to elastomeric membranes and sealants. We select the best product for your foundation type and site.
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.
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.
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.
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 valid.
