Water Heater Leak & Burst Tank Cleanup in McDonough, GA
Water heater leaking from the bottom? A failing tank can dump its whole load at once. Local water heater leak cleanup technicians extract the water and dry your garage, closet or ceiling before it spreads.
Water heater leak cleanup in McDonough, GA means removing the water a failed tank or line released, drying the floors, walls and ceilings it reached, and preventing mold in the closet or attic around it. A standard tank holds 40 to 50 gallons and keeps refilling from the main line until it's shut off, so a burst tank can flood a garage, soak a hallway or drop water through a ceiling in minutes. Water damage technicians extract the water, map hidden moisture with meters and thermal imaging, and dry the structure while your plumber replaces the unit.
Many homes in Henry County's 1990s and 2000s subdivisions still have original or second-generation water heaters, and tanks typically last about 8 to 12 years. That makes tank failures one of the most common sudden leaks in water damage restoration in McDonough.
Water Heater Leaking? Shut These Off First
- Cold water supply. Turn the valve on the cold inlet pipe at the top of the tank clockwise until it stops. If it won't turn, shut off the main water valve.
- Power or gas. For an electric heater, switch off its breaker. For gas, turn the gas control knob to "off" or "pilot."
- Stay clear of hot water. Water from the tank can be scalding.
- Move belongings out of the water's path, especially boxes stored in garages and closets.
- Photograph the tank and the damage.
- Call a plumber for the unit and call us for the water damage.
Why Water Heaters Leak and Burst
- Tank corrosion. Sediment and age wear through the inside of the tank; leaks from the bottom usually mean the tank itself has failed.
- Failed temperature and pressure (T&P) relief valve releasing water down the discharge pipe.
- Loose or corroded inlet and outlet connections at the top of the tank.
- Drain valve leaks at the bottom.
- Clogged or missing drain pan that lets small leaks spread.
- Tankless units leaking from fittings, the heat exchanger or a frozen line in winter.
Garage, Closet and Attic Water Heaters: Where the Damage Goes
| Location | Where water spreads |
|---|---|
| Garage | Across the slab, under drywall at the base of walls, into adjoining rooms and storage |
| Interior closet | Into hallway carpet and pad, under baseboards, into wall cavities and nearby flooring |
| Attic | Through insulation and ceiling drywall into rooms below (see ceiling water damage repair) |
| Crawl space or lower level | Pooling on soil or concrete, soaking joists and insulation (see crawl space water damage) |
Attic water heaters are the most damaging location, because a failure can soak insulation and collapse ceiling drywall in the rooms below.
How Water Heater Flooding Is Cleaned Up
- Confirm the water and power are off and the area is safe.
- Extract standing water from floors, carpet and pad with emergency water extraction equipment.
- Map hidden moisture under flooring, behind baseboards and up walls or through ceilings.
- Remove what can't be saved, such as soaked pad, swollen MDF trim and sagging ceiling drywall.
- Dry the structure with our structural drying setup, monitored daily.
- Treat for mold in closets and attics, where airflow is poor.
- Repair drywall, flooring and trim once the new heater is in and everything is dry.
Does Insurance Cover Water Heater Leak Damage?
Homeowners insurance usually covers the sudden water damage from a burst or failed water heater, such as wet floors, walls and ceilings. It usually doesn't cover replacing the water heater itself, since that's considered wear and tear. A tank that leaked slowly for a long time may be treated as maintenance. Photograph the tank, the leak point and the damage before the plumber hauls the old unit away.

- Add a leak sensor or automatic shut-off valve near the tank
- Flush sediment from the tank as the manufacturer recommends

Water Heater Questions from McDonough Homeowners
Water heater leaking from the bottom: is it an emergency?
Yes. A leak from the bottom usually means the tank is failing and can get worse quickly. Shut off the cold supply and power or gas, and start cleanup right away.
How do I shut off my water heater?
Close the cold water valve on the inlet pipe at the top, then switch off the breaker for electric heaters or turn the gas knob to off or pilot for gas units.
Can a water heater burst?
Yes. Severe corrosion or a failed relief valve can cause a sudden rupture, releasing the full tank and continued water from the supply line until it's shut off.
Is the water from my water heater safe to clean up myself?
It's clean water, but it can be hot. Small amounts on concrete are manageable. Water that reached carpet, walls or ceilings needs professional drying to prevent mold.
Will insurance pay for a new water heater?
Usually not. Policies typically cover the resulting water damage, not the worn-out heater itself.
