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

Drainage System Integration in Merced, CA
Lasting walls waterproofing often requires a solid 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 Merced, CA properties, so water is managed well and moved away from your home's vulnerable areas.
Laundry Room and Utility Wall Waterproofing in Merced, CA
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.
Plumbing Leak Behind Walls in Merced
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.
Commercial Walls Waterproofing in Merced
Beyond residential properties, FBL Plumbing also offers walls waterproofing services for commercial buildings in Merced. Protecting commercial basements, equipment rooms, and underground parking garages from water damage is vital to business operations. We understand the need for minimal disruption and efficient project completion for commercial clients. Our team works with property managers and business owners to implement robust waterproofing solutions that fit the demands of commercial structures and their code requirements.
Exterior Block Wall Waterproofing in Merced, CA
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 for good.
Waterproofing for Older Homes in Merced, CA
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Newer homes across Northern California mostly use PEX or copper with plastic drains, and many owners are repiping older houses to restore water pressure. 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.

Foundation Crack Repair & Sealing in Merced
Even minor cracks in foundation walls can allow serious water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points for good. 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 expensive future repairs.

Frequently Asked Questions About Walls Waterproofing in Merced
Shower wall waterproofing with a membrane system usually runs $1,200 to $3,500 including demolition and backer board, not counting new tile. Exterior block wall sealing often costs $800 to $3,000 depending on size. Below-grade foundation waterproofing generally ranges from $2,500 to $8,000.
Yes. Our workmanship is warrantied, and many membrane systems carry their own manufacturer warranty when installed correctly. We explain the coverage in your written quote.
Interior waterproofing addresses water after it has entered the foundation, usually 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, FBL Plumbing stands behind the quality of our work. We offer comprehensive warranties on our walls waterproofing installations, covering both materials and labor. The warranty details will be outlined in your service agreement, giving you peace of mind about your investment. Our goal is your complete satisfaction and a dry, healthy home.
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 pull 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.
FBL Plumbing works with trusted 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.
