A water heater rarely leaks politely. The tank or a fitting corrodes quietly for years — in a hot, humid Florida garage or attic, often faster than owners expect — and then one day there is water across the floor, or a stain spreading across the ceiling below an attic unit. Here's how to limit the damage and what cleanup typically involves.
First Steps When You Find the Leak
- Shut off the water supply to the heater. Most have a shutoff valve on the cold-water line entering the top of the tank. If that fails or you can't find it, use the home's main shutoff.
- Turn off the energy source if safe. Electric heaters: switch off the breaker only if you can do so without standing in water. Gas heaters: turn the control to off/pilot if it's safely reachable. When in doubt, skip this step and keep your distance.
- Keep clear of water near electrical connections.
- Call (772) 218-9357. Tell us where the heater sits (garage, attic, closet) and how much water you're seeing. We'll connect you with an independent local provider. Independent providers in our network offer 24/7 emergency response.
Garage vs. Attic vs. Closet Heaters — Damage Patterns Differ
- Garage (common here): water spreads across the slab and into stored belongings, drywall edges, and the wall between garage and house. Damage is often visible early if you're home — and quietly extensive if you're not.
- Attic: the worst case. Water moves down through ceilings and walls, sometimes appearing rooms away from the tank. See our ceiling leak page for the signs.
- Interior closet: soaks flooring and wall cavities around the closet; the musty smell afterward often traces to the AC or heater closet.
What Cleanup Typically Involves
Once connected with an independent local provider: confirm the source is off, extract standing water, check moisture in floors/walls/ceilings (including below an attic unit), dry with monitored equipment over several days, and evaluate materials. The heater itself — repair or replacement — is a plumbing matter the provider can discuss or point you on; our referral covers the water damage side.
A Note for Seasonal Residents
A heater failure in an empty home is one of the costliest Florida water events, because nobody is there to shut the valve. If your home sits empty part of the year, having the water shut off at the main while away — a tip many local home-watch services suggest — removes this risk entirely. Returning to a musty smell or warped flooring? Call for an assessment before assuming it's minor.
