The First 24 Hours After a Leak

By the Austin Restoration Pros team · Updated September 2026

Stop the Water Before Anything Else

Every decision after this one is smaller. If the water is coming from inside the building, the fastest fix is usually a valve rather than a bucket. Look first for a shutoff at the fixture itself: under a sink, behind a toilet, on the wall beside a washing machine. If that will not do it, or you cannot reach it, go to the main. On most properties around here the main shutoff sits in a meter box set into the ground near the curb or the property line, with a valve next to the meter that needs a meter key or a wrench. Plenty of houses also have a valve where the supply enters the building or near the water heater.

Two rules apply. If the valve does not turn with reasonable effort, leave it and call, because a snapped valve at the meter turns one problem into two. And if reaching it means standing in water near an outlet, an appliance or an electrical panel, do not. Electricity and standing water are the one combination worth waiting on, and a restoration crew can bring the right equipment.

If the water is coming from outside, from a storm, an overflowing creek or runoff crossing the yard, there is nothing to shut off. Move to keeping people safe and getting a record instead.

Keep People Away From the Real Risks

Three things hurt people in the hours after water gets into a building. The first is electricity: outlets, extension leads, floor boxes and appliances at or below the waterline. Keep off wet flooring anywhere near them and leave the circuits for that area switched off until someone has looked.

The second is a ceiling holding water. Wet drywall is heavy, it sags before it fails, and it usually comes down all at once. Clear the room, do not walk underneath it and do not poke a hole to drain it, whatever the internet says. Turn off the light circuit for that room if the switch is outside it.

The third is contamination. Water from a drain, a sewer line or the street is a health risk, not just unpleasant. Wear boots and gloves, keep children and pets out entirely, do not track through carpeted rooms that were dry, and leave the air conditioning off so the ductwork does not carry it around the building.

Photograph Everything Before You Tidy

The instinct is to start moving things. Take the pictures first. Photograph each affected room from the doorway, the waterline on the walls, the wet flooring, the ceiling, the source if you can see it, and any furniture or possessions that got wet. Video walking through is even better. Note the time you found it and the time you shut the water off.

This matters for two reasons. An insurer will ask what the damage looked like before anyone touched it. And the restoration crew uses it to work out how far the water travelled, which is rarely obvious once furniture has been shifted and towels have been thrown down.

What Is Worth Doing Yourself

Small clean-water spills on hard flooring you can mop up. Beyond that, the useful jobs are the ones that limit further damage rather than fix anything. Lift rugs off wet floors. Move small items, books, electronics and anything made of paper to a dry room. Put foil, plastic or blocks under furniture legs so the finish does not stain the carpet. Open drawers and cabinet doors so air can get in.

What is not worth doing: running a household vacuum over standing water, renting one fan and calling it drying, pulling up flooring without knowing what is under it, or opening windows on a humid Austin afternoon when the air outside holds more moisture than the air inside. Proper structural drying works because dehumidification and airflow are controlled together, and the equipment guide explains why.

Why the Clock Matters in Austin

Warm, humid air is the local complication. Through spring and most of the summer, wet material in an Austin house is sitting in conditions that suit growth, and a couple of days is genuinely enough to change the job from drying into removal. Almost every home here is built on a slab with no basement, so the water spreads sideways under baseboards and into wall bases rather than draining down, and it turns up two rooms away from where it started.

The other local factor is that a lot of damage arrives all at once. In a flash flood, or during a freeze like February 2021, every restoration company in the region is working a queue. Calling early gets you into that queue with the water already off and the damage already photographed. Out in the newer subdivisions where plumbing often runs through the attic, the same principle applies from above: our Leander page covers what that looks like.

Arrange an Inspection

Once the water is off and the photographs are taken, the next step is someone taking moisture readings to find the real edge of the wet area.
