Local Waterproofing Expertise
In New Orleans, waterproofing in New Orleans protects your home and business from constant moisture, humidity, and flooding threats. Our team prevents water intrusion before it becomes damage, saving you from costly repairs and structural decline.
We follow a clear, systematic approach to identify and seal every moisture entry point in your property.
We scan your foundation, walls, roof, and interior for active or hidden moisture. Thermal imaging reveals cold spots where water seeps through.
We recommend sealants, membranes, or coatings matched to your specific structure. Clear timelines and scope prevent surprise costs.
Trained crews apply waterproof coatings, inject sealants, or install drain systems using proven techniques that hold under New Orleans humidity.
We test moisture levels after treatment and return within 48 hours to confirm all seals hold. No hidden problems after you pay.
You'll always know what's happening next—and when.
Specific solutions built for New Orleans moisture challenges and historic architecture.
Basements and crawl spaces in New Orleans sit in constant contact with groundwater and humidity. We inject epoxy sealants into cracks, apply interior membranes, and install sump systems to block moisture before it spreads to structural wood or triggers mold.

Interior sump and drain system installed in Marigny basement, protecting against seasonal seepage.
Many old shotgun houses in Bywater have clay brick foundations prone to seepage. We solve this without tearing up floors.
Flat roofs, skylights, and rusted flashings are common leak sources in New Orleans' older neighborhoods. We seal penetrations, apply protective coatings, and replace failing flashing to stop leaks before they rot attic framing or ceiling drywall.

New metal flashing and silicone seal at roof penetration in Treme property, preventing recurring leaks.
Rain-driven moisture penetrates brick, mortar, and wood siding, especially in historic Creole cottages. We apply water-repellent coatings, repair deteriorated mortar joints, and seal cracks to keep exterior walls dry while preserving original aesthetics.

Moisture-barrier coating applied to brick exterior in Uptown, protecting plaster and interior framing.
New Orleans' humidity naturally promotes mold growth inside walls and attics. Waterproofing alone stops exterior water; we also dehumidify crawl spaces, install vapor barriers, and ventilate damp areas to halt mold before it spreads.

Water damage costs thousands to repair and puts your family's health at risk.
Wood rot, mold, electrical hazards, and foundation failure all trace back to unchecked moisture. Waterproofing costs a fraction of structural repair and gives you 10–15 years of peace of mind.
Water damage in New Orleans develops faster than you think. Mold appears within 48 hours.
We've sealed basements in French Quarter cottages, waterproofed brick walls in Marigny Creole homes, and protected crawl spaces across the city. We know how New Orleans' humidity, rainfall, and historic building codes work—and what fails.
Trusted by homeowners and businesses across the city and metro area.
We work in historic Creole neighborhoods like Marigny, Bywater, and Treme, where 19th-century architecture demands careful waterproofing. We also serve Uptown's grand mansions, Mid-City's residential blocks, and French Quarter properties—anywhere in the greater New Orleans area.
The best waterproofing combines foundation sealing, roof flashing repair, and moisture control. Interior sealants stop basement leaks; exterior coatings protect brick from rain; crawl space vapor barriers prevent humidity mold. For New Orleans' climate and old buildings, layered protection works better than any single fix.

Yes. Breathable water-repellent sealers protect brick while allowing moisture vapor to escape, preserving historic integrity. We match all repairs to original materials and work within local preservation guidelines.
Waterproofing stops water entry, the main trigger for mold. Combined with vapor barriers and dehumidification, it sharply reduces mold risk. Full prevention requires interior moisture control as well.
Within 48 hours of water intrusion, before mold colonizes. We inspect for damage, dry the area, then apply waterproofing to prevent recurrence.
