Waterproofing for Older Homes in Marrero, LA
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Newer construction mostly uses PEX and plastic drains, while older homes often mix copper, galvanized, and cast iron. 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.

Shower Pan Leak Repair and Waterproofing in Marrero, LA
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.
Foundation Crack Repair in Marrero
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 Marrero homes is important to avoid larger, more costly structural issues.
Commercial Wall Waterproofing in Marrero
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 reduce downtime. We also repair the plumbing behind those walls when leaks are found.
Crawl Space Encapsulation in Marrero
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, preventing mold growth and wood rot in the crawl space. Around Marrero, attic and crawlspace heat can accelerate wear on supply lines, drain pans, and any plastic piping in those spaces. An encapsulated crawl space can significantly 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.
Below-Grade and Basement Wall Waterproofing in Marrero
Newer construction mostly uses PEX and plastic drains, while older homes often mix copper, galvanized, and cast iron. 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.
Shower Wall Waterproofing in Marrero
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 reinforcement before new tile is set.

Foundation Crack Repair & Sealing in Marrero
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 indicate structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and costly future repairs.

Frequently Asked Questions About Walls Waterproofing in Marrero
The cost of walls waterproofing in Marrero, LA can vary widely, typically ranging from $3,000 for interior crack sealing to $15,000 or more for extensive exterior foundation waterproofing with drainage systems. Factors like the size of the area, severity of water damage, chosen methods, and accessibility all influence the final price. We provide detailed, transparent quotes after a thorough inspection.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Marrero may be required. Simple crack repairs usually do not need a permit. Beau's 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.
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.
