Sump Pump Installation and Repair in Mandeville, LA
Sump pumps are a critical part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during heavy storms. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed properly so water does not circulate back toward the foundation.
Exterior Foundation Waterproofing in Mandeville
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most effective 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. Low-lying areas have a high water table and settling ground, which can cause sewer lines to sag, crack, or separate over time. Proper drainage solutions, such as French drains, are also integrated to divert water away.
Basement Wall Sealing in Mandeville, LA
Basement wall sealing is a critical part of walls waterproofing. Long, hot summers and heavy humidity are the main stress on plumbing in Louisiana, driving condensation, mold, and overworked water heaters. 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 Mandeville, LA basement.
Foundation Crack Repair in Mandeville
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 proven epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks promptly in Mandeville homes is crucial to avoid larger, more costly structural issues.
Shower Pan Leak Repair and Waterproofing in Mandeville, 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 & Sealing in Mandeville
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 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 indicate structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and expensive future repairs.

Interior Walls Waterproofing in Mandeville, LA
Interior walls waterproofing focuses on managing water that has already penetrated the foundation walls. This typically 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 is suitable where exterior access is limited.

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.
The duration of a walls waterproofing project varies depending on its scope. Minor crack repairs might take a few hours, while an interior drainage system could take 1 to 3 days. A full exterior foundation waterproofing project, involving excavation around the entire home, could take 3 to 7 days or more. We provide a clear timeline during our initial consultation.
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.
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.
Look for signs such as damp or wet spots on basement or crawl space walls, a musty odor, visible mold or mildew growth, efflorescence, a white powdery residue, on concrete or brick, and standing water. Cracks in foundation walls or bowing walls also point to potential water entry issues. If you notice any of these, it's wise to get a professional assessment.
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 mean water is getting behind.
The duration of a walls waterproofing project varies a lot. Smaller jobs like interior crack sealing might take a day or two, while extensive exterior waterproofing with excavation and drainage system installation could take several days to over a week. We'll provide a clear timeline during your first visit.
