An emergency water damage call from a San Marcos rental usually opens with the same problem: nobody in the house knows where the water shuts off. Tenants are not shown the valve, the water heater sits in a closet that is padlocked or inside a unit nobody can open, and a house divided into units often still has one meter and one main at the street serving all of it. So at one in the morning the answer is frequently the valve at the street, which cuts water to everybody on the property, and at that hour that is the right call.
Before that, look for a fixture valve, because it is faster and it does not shut four other people off. Under a toilet or a sink there is a small oval or lever handle on the riser going into the wall or the floor. A washer has two of them behind the machine. If water is coming through your ceiling from the unit above, none of those valves are in your unit at all, and the fastest thing anyone can do is get somebody to that door while another person finds the main. If water has reached outlets or is running down a wall with a switch on it, that circuit goes off before anybody wades in.
What happens between the call and the truck
The crew loads and rolls while you are still on the phone, and the technician stays on the line: what to lift, what to block up, what to pull out of the bottom cabinets, and what not to touch. That conversation is worth more here than almost anywhere else we work, because this is the far south end of the map we cover and the drive is real. The crew confirms the source is off, walks the floor with a meter until the wet area has a boundary, extracts, takes out what the readings condemn, and leaves air movers and a dehumidifier running before the truck goes. Photos and readings start at the front door, since that file is far easier to build now than to reconstruct for an adjuster next week.
- Somebody on the phone who tracks down your shutoff while the truck loads
- Extraction and drying gear aboard before the truck leaves the yard
- The wet edge found with a meter, including where it crossed into another unit
- Photographs and numbers starting at the front door, for whoever files

If what is on the floor came back up out of a drain, stop and wait for the crew. That is category three water, and porous material it touched leaves the house rather than getting dried in place. Everything else gets smaller the sooner it stops moving. Call (512) 271-5099 with the address, the unit, and what gave out.
