24/7 Emergency Help for Leaking Water Heaters in Fort Myers
Turn off the cold-water supply to the heater and cut its power or gas before anything else.
Water from a heater closet spreads under baseboards, carpet and vinyl plank into nearby rooms, so the wet area is usually bigger than the puddle.
The plumber replaces the heater; the floors, walls and cabinets around it still have to be measured and dried.
Water heater leaking right now? Do this first
- Turn off the cold-water valve on the pipe going into the top of the heater. If it won't turn or the leak is heavy, shut off the main water to the house.
- Cut the power or gas. For an electric heater, switch off its double breaker at the panel. For gas, turn the control knob to "Off" or "Pilot." If you smell gas, leave the house and call the gas company from outside.
- Stay away from hot water. Water near the tank can be scalding. Let it cool before you reach into it.
- Keep clear of wet outlets and extension cords on the garage floor.
- Move boxes, rugs and stored items out of the water, and lift anything sitting on the garage or closet floor.
- Photograph and video everything before cleanup: the tank, the label with its age, the floor, and the walls around it.
- Start drying the same day. In Fort Myers humidity, mold can start within 24 to 48 hours.

Why water heaters leak
Most tank water heaters last roughly 8 to 12 years. After that, the steel tank inside can rust through, and once it does, it can't be repaired.
| Where the water is coming from | What it usually means |
|---|---|
| Bottom of the tank | Tank corrosion; usually means replacement |
| Top of the tank | Loose or corroded supply connections or a failing fitting |
| The T&P relief valve or its discharge pipe | Pressure or temperature too high, or a worn valve |
| The drain valve near the bottom | Worn or loose valve; sometimes a simple fix |
| Water around the base with a dry tank | Condensation, a nearby AC drain, or another leak |
A plumber confirms the cause. If the tank itself is leaking, plan on a replacement rather than a patch.
Where water heaters sit in Fort Myers homes, and where the water goes
Garage. The most common spot in Lee County single-family homes. Water spreads across the slab, under the door into the house, and into the bottom of garage drywall and stored boxes.
Interior closet. Common in condos, townhomes and some single-family homes. Water soaks the carpet or flooring outside the closet, the hallway, and the walls on both sides.
Attic. Less common, but the worst case. A leaking attic heater soaks insulation and comes through the ceiling. See ceiling leak help.
Condo utility closets. In multi-story buildings, a failed heater can leak into the unit below and the walls between units. See condo water damage.
How water heater leak cleanup works
- The plumber shuts down and replaces the heater or repairs the fitting.
- Standing water is extracted from the slab, carpet and closet floor with emergency water removal equipment.
- Moisture is mapped under flooring and up the walls with meters and a thermal camera, including rooms next to the closet or garage.
- Materials that can't be dried are removed, such as soaked carpet pad, swollen baseboards, particle board shelving and the lower part of wet drywall if needed.
- The structure is dried with dehumidifiers and air movers, logged daily until it reaches a measured dry standard. See how structural drying works.
- Repairs follow once everything reads dry.
Most clean-water heater leaks dry in about 3 to 5 days if drying starts quickly. Leaks that ran for days, or water that soaked under vinyl plank, can take longer.
Is water heater water clean?
Water straight from the supply line is clean water, Category 1. But water that sits on a garage floor, soaks through dirty carpet or runs for days can become Category 2, which means more cleaning and more removal. That's one more reason not to wait.
Slow leaks vs sudden bursts
| Slow leak | Sudden burst | |
|---|---|---|
| What you notice | Rust stains, damp baseboards, musty smell, a small puddle that keeps coming back | A flooded garage or closet, water running across the floor |
| Hidden damage | Often more than it looks, under flooring and inside walls | Spread across a large area quickly |
| Mold risk | Higher, because water has been there longer | Lower if drying starts the same day |
| Insurance | Long-running leaks are often excluded | Sudden damage is often covered |
Warning signs before a water heater fails
- Rust-colored hot water or rust at the tank's base
- Rumbling or popping sounds as sediment builds up
- Moisture or small puddles around the base
- A tank older than about 10 years
- Corroded fittings on the pipes at the top
If you see these, have a plumber look at the heater before it fails, and make sure a drain pan is installed under it, especially in closets, attics and condos.
How to lower your risk
- Install a drain pan under the heater, piped to a drain where possible.
- Add a leak alarm or automatic shut-off valve that closes the supply when it senses water.
- Flush the tank as the manufacturer recommends to reduce sediment.
- Know where the cold-water shut-off is and make sure it turns.
- Plan replacement before the tank hits the end of its life, rather than after it floods the garage.
- Seasonal homes: turn off the heater and the main water when you leave for an extended time.
How much does water heater leak cleanup cost?
You're paying for the plumber to replace the heater and for the cleanup. These are national 2026 ranges for the water damage side.
| Work | Typical 2026 range |
|---|---|
| Emergency water extraction | $500 to $2,000 |
| Category 1 extraction and drying | $3 to $4 per sq ft |
| Category 2 extraction and drying | $4 to $6.50 per sq ft |
| Drying equipment, whole job | $800 to $3,000 |
| Moisture monitoring, 3 to 5 days | $300 to $600 |
| Drywall removal and replacement | $1.50 to $3 per sq ft |
A garage leak caught the same day is usually at the low end. A closet leak that reached carpet, hallways and the unit below costs more. These are national ranges, not a quote; your price is set after an inspection and should be in writing before work starts. See the full water damage cost guide.
Does insurance cover water heater leak damage?
- The resulting water damage to floors, walls and belongings is often covered when the failure was sudden.
- The water heater itself usually isn't covered, because tanks wear out over time.
- Long-running leaks may be excluded as continuous or repeated seepage.
- Condos: damage that reaches other units can involve the association and other owners' policies.
Keep photos, the heater's age label and the plumber's invoice showing what failed. Read how insurance handles water damage in Florida.
Questions about water heater leaks
What do I do first when my water heater is leaking?
Turn off the cold-water valve at the top of the heater, then cut its power at the breaker or set a gas heater to "Off." If the leak is heavy or the valve won't turn, shut off the main water to the house.
Is a leaking water heater an emergency?
Yes, if water is spreading or the tank is leaking from the bottom. A leaking tank can fail completely without warning. Shut it down and get the water out the same day.
Can a leaking water heater be repaired?
A leaking fitting, drain valve or relief valve can often be repaired. A tank leaking from the bottom because of corrosion usually needs to be replaced.
Can I still use hot water if the heater is leaking?
No. Shut off the supply and power or gas until a plumber has checked it. Running a leaking heater keeps adding water and can damage the elements or burner.
My water heater leaked into the garage. Do I need to worry about the walls?
Yes. Water on a garage slab often wicks into the bottom of the drywall and can run under the door into the house. Have the walls and nearby rooms checked with a moisture meter.
How long does it take to dry after a water heater leak?
Most clean-water leaks dry in about 3 to 5 days with commercial equipment. Leaks that soaked under vinyl plank, reached several rooms or ran for days take longer.
