Water Heater Leak Water Damage Cleanup

A tank-style water heater keeps refilling as long as the cold supply is open, so a leaking tank won't run out of water on its own. Work through this before you call anyone:

1. Stop the water. Most heaters have a shutoff valve on the cold line going into the top of the tank. If it won't turn, or you can't find it, shut off the main. The Texas Department of Insurance puts it plainly: if you have a sudden leak, shut your water off at the main.
2. Cut the energy. For an electric heater, switch off its breaker, but only if you can reach the panel without standing in water. The CDC is firm on that. For gas, follow the instructions on the heater's label to turn the control off.
3. If you smell gas, get out. Ready.gov says that if you smell gas or hear a blowing or hissing noise, open a window, get everyone out quickly and call the gas company from a neighbor's home. Only a qualified professional should turn the gas back on.
4. Mind the heat. Water coming out of the tank can be hot enough to burn. Give it time and keep kids and pets away.
5. Take pictures, then make two calls: a plumber for the heater, and us for the water.

Let's be clear about who does what. Texas Damage Response doesn't repair, replace, drain or relight water heaters, and we don't do plumbing or gas work. A plumber takes care of the heater.

What the water reached is ours. That's water extraction to get it off the floor, structural drying for the drywall, baseboards and framing, and moisture monitoring until the numbers say it's dry. With the water shut off, we don't have to wait for the new heater to go in before we start. Our crew comes ready to work on the first visit.

Where your heater sits decides what gets wet. Around Central Texas, the heater usually lives in one of three places.

A burst tank is loud and obvious. The whole tank ends up on the floor, and more keeps coming while the supply stays open. You know right away.

The slow leak is the sneaky one. A weeping fitting or a drip from the relief valve line can soak the closet floor, the bottom plate of the wall and the drywall behind the heater for weeks without much showing. By the time the baseboard swells or the room smells musty, the framing has been wet a long time. The EPA says to dry water-damaged areas within 24 to 48 hours to prevent mold growth, and a slow leak blows past that window before anyone notices. If mold has started, that part of the job is mold remediation.

The difference matters for insurance, too. The Texas Department of Insurance says most policies cover sudden and accidental water damage and usually won't cover damage from gradual leaks. Which one you have is your carrier's decision. We help document the damage and work with your insurance carrier throughout the restoration process, and the claim and the deductible stay yours. Our insurance claims page explains where we fit.

Drying around a water heater usually means pulling baseboards and, where the drywall has wicked water up, cutting out the wet bottom section so air can reach the studs and the bottom plate. Saving drywall that's saturated isn't worth the risk of trapping moisture in the wall.

Once the readings confirm everything is dry, we can rebuild it. We rebuild the projects we restore, so new drywall, baseboards, paint and flooring go back in through our reconstruction team, with the plumber's new heater in place. We do this for homes in San Antonio, Seguin and New Braunfels, among other towns.
