Marsh Water Damage Restoration handles water, mold, and storm damage across San Antonio, from the limestone homes of King William to the stucco subdivisions spreading west of Loop 1604. San Antonio sits on the edge of Flash Flood Alley, so sudden cloudbursts overwhelm drainage fast, and the summer heat turns damp drywall into a mold problem within 48 hours. If you’ve got water where it shouldn’t be, call (325) 252-3917 and a live person answers, day or night.
Why San Antonio Homes Are Different
San Antonio’s housing stock spans three distinct eras, and each one fails differently when water gets involved. In the historic core, King William and Monte Vista homes sit on pier-and-beam foundations with limestone walls and lime plaster that wicks moisture upward. These houses need drying strategies that account for crawl spaces and breathable masonry, not just surface extraction. The mid-century brick veneer ranch homes that fill neighborhoods inside Loop 410 were built before modern moisture barriers, so a slab leak can travel under flooring for days before it shows. Then there’s the new construction in places like Alamo Ranch and the far west side, where water heaters in attics are standard. A failed T&P valve up there sends water through two stories of drywall before anyone hears it. Add in San Antonio’s summer humidity, and the window for simple drying closes quickly. Psychrometric readings, measuring the moisture in the air, tell us when the structure is genuinely dry, not just dry on the surface.
Restoration work we handle






Our Main San Antonio Services
Most San Antonio homeowners reach out to us for one of three reasons: a water event that needs immediate extraction, mold that has already taken hold, or storm damage from a hail or wind event. Each has its own dedicated San Antonio page with full pricing and process details.
Water Damage Restoration in San Antonio
San Antonio’s water damage calls range from burst supply lines in historic pier-and-beam homes to appliance failures in two-story production builds. We extract the standing water, map the moisture spread, and set professional drying equipment from Dri-Eaz and Phoenix before mold gets a foothold in the humid air. Every job gets a written price before we start. Water Damage Restoration in San Antonio covers what to expect in this city, including how we handle slab leaks and attic water heater failures.

Mold Remediation in San Antonio
San Antonio’s heat and humidity mean mold moves fast after any water event, and it also grows on its own in poorly ventilated pier-and-beam crawl spaces. Our crews contain the affected area, remove contaminated material, and treat surfaces so mold doesn’t return. We document everything, because insurance claims often depend on what we capture before demo begins. Mold Remediation in San Antonio explains our process and what it costs in this market.

Storm Damage Restoration in San Antonio
Flash Flood Alley storms hit San Antonio with intense rain, and spring brings hail that shreds roofs and siding. When water gets in through a damaged roof or flashing, the restoration clock starts. We tarp and board up first, then extract and dry. Storm Damage Restoration in San Antonio walks through the storm-specific process, including how we coordinate with insurance adjusters.

You’ll get a written price before any demo or drying begins, and that price doesn’t change once work starts.
