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

Laundry Room and Utility Wall Waterproofing in Laconia, 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 head off costly drywall repairs.
Foundation Crack Repair & Sealing in Laconia
Even minor cracks in foundation walls can allow significant water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points permanently. 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.
Waterproofing for Older Homes in Laconia, NH
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. The housing stock in New Hampshire includes many old farmhouses and village homes, often with cast iron drains and galvanized supply lines. 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 respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.
Plumbing Leak Behind Walls in Laconia
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.
Waterproofing Costs vs. Repeat Water Damage in Laconia, NH
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 clearly.
Below-Grade and Basement Wall Waterproofing in Laconia
The housing stock in New Hampshire includes many old farmhouses and village homes, often with cast iron drains and galvanized supply lines. Wherever a home has a basement or below-grade walls, heavy rain and snowmelt can push water through foundation walls and cracks. We seal cracks with injection products, apply interior or exterior waterproofing and install drainage where needed. A sump pump may be added if groundwater collects.

Commercial Wall Waterproofing in Laconia
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 limit downtime. We also repair the plumbing behind those walls when leaks are discovered.

Frequently Asked Questions About Walls Waterproofing in Laconia
The cost of walls waterproofing in Laconia, 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 clear, itemized quotes after a thorough inspection.
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.
We use a range of high-performance waterproofing membranes and coatings depending on the application and foundation type. These can include liquid asphalt-modified polyurethane, rubberized asphalt membranes, bentonite clay systems, and crystalline coatings. Brands often include trusted names known for their durability and effectiveness in preventing water penetration.
Yes. Our workmanship is warrantied, and many membrane systems carry their own manufacturer warranty when installed correctly. We explain the coverage in your written estimate.
Skilled DIYers can roll on liquid membranes, but mistakes at seams, corners and drains often lead to leaks. Shower pans also require correct slope and flood testing. Professional installation lowers the risk of hidden water damage.
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.
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.
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 suggest water is getting behind.
