What a licensed remediation job actually involves, in the order it happens. Every step below is the contractor's work, not ours.
-
Step 1: Assessment
A licensed assessor establishes whether there is growth, how far it extends, and where the moisture is coming from.
-
Step 2: Containment
Barriers and negative air pressure go up first, so disturbing material does not move spores into clean rooms.
-
Step 3: Removal
Porous material that cannot be cleaned comes out - drywall cut past the moisture line, insulation, carpet pad, cabinet bases.
-
Step 4: Drying
Dehumidifiers and air movers bring the structure back to a dry standard, with readings logged from the material rather than the surface.
What drives moisture problems in San Antonio
Our local pros provide mold removal services in San Antonio and the surrounding area, including New Braunfels, Schertz, and Converse. Much of the city lies over the Edwards Aquifer recharge zone, and it is the driest of the major Texas metros at 32.38 inches of rain a year.
Housing stock
San Antonio's housing has a median construction year of 1985, and roughly 59% of units were built in 1989 or earlier. Near-downtown districts — King William, Lavaca, Monte Vista — hold late-1800s to 1920s stock in limestone, masonry, and pier-and-beam frame, while post-war expansion filled Bexar County with slab-on-grade ranch homes. Soils shift from shallow caliche and limestone over the northern aquifer-recharge zone to expansive clay on the south and east sides.
Climate and water risk
San Antonio is drier than the Texas coast, averaging 32.38 inches of rain a year (1991–2020 normals at the airport), but it sits at the wet edge of Flash Flood Alley below the Balcones Escarpment. May is the wettest month at 4.40 inches, with a second push in September (3.88 inches) and October (3.75 inches) as tropical moisture arrives. Storms stall against the escarpment and drop several inches in a few hours, so most damage comes from sudden runoff rather than steady rain.
Common moisture and mold problems in San Antonio
- Flash flooding off the Balcones Escarpment that fills low crossings and slab homes within hours of a stalled storm
- Expansive clay on the south and east sides cracking slabs and letting water track under floors
- Slow-drying pier-and-beam crawlspaces beneath late-1800s King William and Lavaca homes
- Wall-cavity condensation during 100-degree summers when closed-up, air-conditioned houses trap humidity

Frequently asked questions
Can San Antonio's summer heat cause water damage on its own?
It can. Through 100-degree stretches a house stays closed up and air-conditioned, warm humid air meets cool wall cavities and duct runs, and the condensation that forms has nowhere to dry. It surfaces as staining or musty air with no leak behind it, most often around an attic air handler or on a shaded exterior wall.
Does it matter which side of San Antonio a home sits on?
It changes how the water behaves. Over the recharge zone to the north, shallow caliche and limestone shed runoff toward a house rather than absorbing it. On the south and east sides the ground is expansive clay that cracks through drought and lets water track beneath a slab. One storm can produce two different problems.
Why does flooding hit San Antonio hard if it's a dry city?
Because the rain arrives all at once. San Antonio averages only about 32 inches a year, but storms stall against the Balcones Escarpment and drop several inches in hours, so creeks and low crossings flood fast. A home can take on runoff in a single May or October storm even during an otherwise dry year.
