When a water heater fails, the tank can empty onto the floor within minutes, and a standard residential tank holds a few dozen gallons. In Owings Mills that water usually spreads through a basement, utility closet or laundry room, then wicks into drywall and out under flooring. Water heater leak cleanup means removing the water, drying the room and documenting the loss for your insurer, and our 24/7 line is open now.
This page covers tank and connection failures. If the source is a washing machine, dishwasher or refrigerator line, the appliance leak page applies instead.
Water heater leaking right now: what to do
Never touch a heater or its wiring while standing in water. If you smell gas, leave and call the gas utility or 911 first.
- Turn off the power to an electric unit at the breaker, or set a gas unit to pilot or off, only if the area around it is dry and safe.
- Close the cold water supply valve on the line feeding the tank, usually on top of the heater.
- If water is rising and you cannot reach the valve safely, close the main water valve.
- Move belongings off the floor and keep everyone out of standing water near the unit.
- Call the 24/7 line and tell us how far the water has spread.
Why water heaters leak
Tanks corrode from the inside, and a slow weep at the base can turn into a full failure. Other causes include a stuck temperature and pressure relief valve, loose supply connections and a failed drain valve. Sediment buildup speeds up corrosion.
Ask your plumber the age of your heater and when the anode rod was last checked. A unit approaching the end of its life is cheaper to replace on your schedule than after a flood. Replacement is plumbing work, and Baltimore County requires permits for plumbing and electrical work done by licensed trades.
What the water reached
Heaters sit in basements, garages and closets, so water often runs toward the lowest drain or seam. Finished basements take the worst of it because carpet, pad and lower drywall absorb water fast.
We check the heater room first, then the rooms next to it, because water crosses door thresholds and runs along baseboards. Moisture meters and a thermal camera show wet drywall and flooring that looks dry from the surface.

Cost factors and insurance
Sudden failure of a water heater is the kind of sudden and accidental event homeowners policies often cover for the resulting water damage, while the heater itself is frequently excluded as wear and tear. Check your policy or ask your insurer.
- How much water the tank released and how long it ran
- Whether the room is finished or bare concrete
- Carpet, pad and drywall that must be removed
- Drying days and equipment count
- Rebuild scope after drying

Frequently asked questions
Yes. Tanks tend to fail without warning, and our dispatch line answers 24/7. The dispatcher walks you through the tank shutoff first, then lines up a crew for same-day response if one is free.
No. Replacement is plumbing work. We handle the water removal, drying and documentation, and we coordinate timing with your plumber.
A steady puddle can mean a failing tank or a loose connection. Shut the cold supply, call a plumber and consider a moisture check, because slow leaks soak flooring and drywall unseen.
Often the resulting water damage is covered when the failure is sudden, but the heater is typically not. Policies vary, so check yours or call your insurer.
