Waterproofing for Older Homes in Ballwin, MO
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Older brick homes in Missouri often still have galvanized supply pipe and cast iron drains, which corrode and narrow over time. 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 Ballwin
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 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 costly future repairs.
Waterproofing Costs vs. Repeat Water Damage in Ballwin, MO
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.
Cost-Effective Waterproofing Solutions in Ballwin, MO
We believe in providing honest and cost-effective walls waterproofing solutions without cutting corners on quality. Our team will conduct a thorough assessment of your property in Ballwin to recommend the most appropriate and economical waterproofing strategy. From detailed estimates to explaining the long-term savings of preventing water damage, we make sure you understand your investment. We use durable materials and proven techniques to provide lasting protection, reducing the chance of future repairs. Our goal is to deliver value and peace of mind.
Exterior Block Wall Waterproofing in Ballwin, MO
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.
Shower Wall Waterproofing in Ballwin
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.
Below-Grade and Basement Wall Waterproofing in Ballwin
Older brick homes in Missouri often still have galvanized supply pipe and cast iron drains, which corrode and narrow over time. 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 builds up.

Commercial Wall Waterproofing in Ballwin
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 Ballwin
Shower wall waterproofing with a membrane system typically 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 usually 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.
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.
Damp proofing is a less robust solution, typically a spray-on asphalt coating that resists soil moisture but isn't designed to withstand hydrostatic pressure. Waterproofing uses stronger membranes, coatings, or drainage systems specifically engineered to prevent liquid water from entering, even under pressure. For basements or crawl spaces in areas with high water tables or heavy rainfall, waterproofing is the right choice.
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 ineffective results, wasted money, and worse water damage over time.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Ballwin may be required. Simple crack repairs usually do not need a permit. FGV Plumbing will help you determine if a permit is necessary for your project and handle the application process if needed.
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 reduces the risk of hidden water damage.
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 well-known names known for their durability and effectiveness in preventing water penetration.
