In San Antonio homes built before 1970 in King William and Southtown, water from roof leaks or plumbing failures often saturates gypsum board behind baseboards and at seams. We remove affected sections to the nearest stud, treat framing with antimicrobial solutions, and install new 1/2-inch or 5/8-inch Type X drywall to match existing fire ratings. Hot summers push indoor humidity above 60 percent, so we run commercial dehumidifiers until moisture readings drop below 12 percent before taping and texturing.
River Walk and Downtown high-rises with stucco exteriors trap moisture against sheathing during mild winters when condensation forms on cooler interior walls. Technicians at White Water Restoration LLC map every wet area with infrared cameras before cutting, then feather new joint compound three to four coats to blend with original orange-peel or knockdown textures common in Alamo Heights ranches. This prevents telegraphing lines once paint is applied.
Bexar County code requires minimum 1/2-inch drywall on garage walls adjoining living space. After extraction, we verify insulation is dry or replaced, then install new panels with the correct screw spacing and fire-tape edges where needed. Homeowners in these older neighborhoods often discover hidden mold in HVAC returns once drywall is opened, requiring additional containment before repairs continue.
We match existing paint sheen and color using local Sherwin-Williams or Benjamin Moore stores rather than leaving mismatched patches. Final walkthrough includes checking every seam under work lights so no ridges remain visible after the homeowner repaints.
Technician insight
In San Antonio the thing that catches most people out with Drywall Repair is how quickly mild winter condensation plus poor attic ventilation in pre-1960 King William and Southtown homes re-wets new board if we do not also address the roof leak or ridge vent first.
Southtown Bungalow Lower Wall
A burst supply line soaked the base of two bedroom walls during a mild January cold snap. We found framing still damp behind original plasterboard and removed four linear feet per wall. After 60 hours of drying and new Type X installation, the homeowner could repaint without visible seams.

How it works
- 1
Moisture Assessment
Technicians use infrared cameras and pin meters to locate every wet area in walls and ceilings before any cutting begins.
- 2
Containment And Removal
Plastic barriers isolate the work zone while saturated drywall is removed to clean studs and prevent spore spread.
- 3
Drying Verification
Commercial air movers and dehumidifiers run until readings stay below 12 percent, typically 48 to 72 hours in San Antonio humidity.
- 4
New Drywall Installation
New panels are hung, taped, and coated in multiple layers to match original texture before priming.
- 5
Final Blend And Cleanup
Edges are feathered, texture matched, and the site is vacuumed so only the repaired section remains visible.
Pricing
Most drywall repair jobs after water damage fall between a few hundred and several thousand dollars depending on square footage and access.
