Get your free estimateFast, Reliable Water Damage Repair Across San Antonio
Water damage repair in San Antonio typically runs between $850 and $4,200 depending on the source and how far the water traveled. Most jobs from a burst pipe or supply line leak land in the $1,100 to $2,800 range when caught within the first 24 hours. We’re on-site fast because we know that in this city’s hot, humid climate, wet drywall starts smelling sour within 48 hours and mold colonizes shortly after. Call (325) 413-9949 and a live person answers, 24/7, not a voicemail.
We work across San Antonio, from Alamo Heights to Stone Oak to the neighborhoods inside Loop 410, and we know the homes here. Slab-on-grade construction, expansive clay soil, cast-iron drain lines from the 1960s and 70s. These are not abstract concepts to us. They’re the reason water ends up under your tile, behind your baseboards, and inside wall cavities without you ever seeing a puddle.
Why Wendell Restoration San Antonio Is San Antonio’s Preferred Water Damage Repair Company
Wendell Restoration San Antonio is part of the Relay Home Co. family, founded in 2006, and this location is independently owned and operated. Our Water Damage Repair crews work under IICRC, RIA, and IFA standards, which means the drying process follows documented protocols, not guesswork. Every job includes a written price before any work starts. Not an estimate range. The actual number, in writing, before a single tool comes off the truck.
Blake Sorensen leads our San Antonio team, and the standard he set is simple: background-checked, uniformed technicians show up with a live arrival time you can track, not a four-hour window. You get before-and-after photos by text, so you can see exactly what was done. And every repair carries the 365-Day Done Right Promise in writing: if it’s not done right, we make it right, plus a free second visit if the repair fails. That’s not a slogan. It’s on the invoice.
Restoration work we handle
Burst Pipe Cleanup in San Antonio
Burst Pipe Cleanup in San Antonio is most often triggered by cast-iron supply lines and drain lines stressed by shifting clay soil, especially in slab-on-grade homes built before 1985. When the pipe fails, Category 1 water (clean water from a supply line) moves under the slab and wicks up into walls, baseboards, and flooring. The cleanup starts with extraction, then moisture mapping across the slab to find how far the water traveled, then structural drying with professional equipment. A typical burst pipe cleanup in San Antonio homes runs $1,200 to $3,400, depending on whether water breached wall cavities or stayed contained to one room.
What We Do First
We stop the source, then map the water. Using thermal imaging and penetrating moisture meters, we trace the path of water under tile, laminate, and carpet. You’d be surprised how often a small puddle in the kitchen means water traveled 15 feet under the slab to the hallway closet. That’s why we never skip mapping on slab foundations.
Drying a Slab Without Tearing Everything Out
When water sits under flooring on a slab, drying means creating airflow through the affected cavities and monitoring humidity levels daily. We use Dri-Eaz extraction units, XPOWER air movers, and Phoenix dehumidifiers, and we track drying logs until moisture readings return to the home’s pre-loss baseline. If we can dry in place, we will. If water sat for days, we’ll tell you honestly that flooring removal is the cheaper long-term option.
Drywall Water Damage Repair in San Antonio
Drywall Water Damage Repair in San Antonio homes is usually the second phase after a slab leak or burst supply line behind a wall. Wet drywall wicks moisture upward, and by the time you see staining or bubbling paint, the water has often been present for days. Repair means cutting out the saturated section, treating the framing with antimicrobial agents, and replacing with new drywall, texture-matched and painted. In San Antonio, drywall water damage repair typically costs $450 to $1,900 depending on the height of the water line and whether insulation or trim also needs replacing.
When to Replace vs. Dry In Place
Drywall exposed to Category 1 water from a clean supply line can sometimes be dried in place if we arrive within a few hours and the water didn’t soak the insulation. But once drywall has been wet for more than 48 hours, or if the water came from outside or a drain line, replacement is the only safe option. We don’t play games here. If it needs to come out, we say so.
Matching Texture and Finish
San Antonio homes range from smooth-wall modern builds in Stone Oak to orange-peel and knockdown textures common in 1980s and 90s neighborhoods like Thousand Oaks and Cibolo Canyons. Our repair techs match the existing texture so the patch doesn’t scream “repair job” every time you walk past it.
Trusted Brands We Service in San Antonio
We deploy professional restoration equipment from Dri-Eaz, Phoenix, XPOWER, B-Air, and Injectidry, and we stock parts and supplies locally so San Antonio jobs don’t wait on shipping from Dallas or Houston. Injectidry systems, in particular, let us dry wall cavities and under cabinets without ripping out finished surfaces, which matters when you have custom trim or limestone entryways we’re trying to preserve. We also follow IICRC, RIA, and IFA standards on every job, which is the same certification framework used on large commercial loss sites. You get the same process, just sized to your house.
Common Water Damage Repair Problems We See in San Antonio Homes
- Slab leaks from expansive clay movement. San Antonio sits on some of the most reactive clay soil in Texas. When the ground shifts through wet-dry cycles, pipes under slab foundations flex and crack, sending water under floors slowly over weeks or months.
- Pooling water against foundations on the northwest side. The limestone-heavy soils near Helotes and the Dominion don’t absorb water quickly. After a heavy rain, water pools against foundation walls and finds its way through hairline cracks.
- Cast-iron drain line failures in older Loop 410 neighborhoods. Homes built from the 1950s through the 1970s often have original cast-iron drains under the slab. Clay movement stresses these rigid pipes until they crack, causing recurring water damage in the same wall or floor area.
- Rapid mold growth in humid summers. A home that stays wet for 72 hours in San Antonio’s July humidity is not the same as a wet home in El Paso. Mold moves fast here, which is why we prioritize same-day dispatch for water events.

FAQs About Water Damage Repair in San Antonio
Mold can begin colonizing wet drywall within 48 to 72 hours in San Antonio’s warm, humid climate, especially during spring and summer. In a home with a slab leak that’s been running for weeks unnoticed, mold is often already established behind the baseboards by the time moisture mapping finds the leak. If you suspect a slab leak, call (325) 413-9949 and we can dispatch a technician to map the moisture before it becomes a mold problem.
Yes. Category 1 water from a burst supply line is clean at the source and can sometimes be dried in place if we arrive quickly. Flash flood water is Category 3, meaning it carried soil, sewage, or other contaminants into your home. That requires full antimicrobial treatment, controlled demolition of saturated materials, and more aggressive drying protocols. The difference matters for both safety and cost.
The northwest side sits on shallower, limestone-heavy soil that drains slowly compared to other parts of San Antonio. When a storm drops 3 inches in an hour, the ground can’t absorb it fast enough, and water sheets toward the lowest point, which is often a foundation line. Homes in this area benefit from French drains and grading corrections, but when water does get in, we dry it out and repair the damage the same way we would anywhere else in the city.
Recurring water damage from a cast-iron drain line usually means the pipe has cracked or collapsed under slab movement. Cleaning up the water is only half the job. The pipe itself needs evaluation, often with a camera scope, before any drywall or flooring repair makes sense. We’ll dry and repair the damage, photo-document everything for your insurance claim, and refer you to a licensed plumber we trust for the pipe repair.
Sometimes. If the leak is caught early and the water didn’t sit for more than a few days, we can often use Injectidry systems and targeted air movement to dry under tile or laminate without pulling it up. But if moisture has been trapped under flooring for weeks, removal is usually the only way to prevent subfloor rot and mold. We’ll show you the moisture readings and explain the trade-offs before any work starts.
