The short answer

Check for Visible Water Damage

Start by looking at your electrical panel, outlets, and any switches that may have been near the water. If you see water stains, rust, or moisture on the panel, do not touch it. Even a small amount of water inside the panel can cause a short circuit or shock.

Also check the walls and ceiling for sagging or discoloration, which can signal hidden water near wiring. If any outlet or switch feels warm or looks discolored, leave it alone. You can use a flashlight to inspect dark corners, but keep your hands dry and wear rubber-soled shoes for extra safety.

  • Look for standing water near the panel
  • Check for rust or corrosion on breakers
  • Inspect for burn marks or melted plastic
  • Feel for warmth on outlets or switches
  • Listen for buzzing or crackling sounds
  • Smell for a burning or fishy odor

Know the Risks of Turning It On

Turning power back on after water damage can be dangerous. Water conducts electricity, so even a small amount inside the system can cause a shock, fire, or damage to your appliances. The risk is highest if the main panel was submerged or if floodwater reached any wiring.

If you have any doubt, do not risk it. An electrician can safely test the system and tell you what needs to be replaced. In the meantime, keep the main breaker off and avoid using any electrical devices that were near the water.

What to Do Before You Flip the Breaker

First, dry out the area as much as possible. Open windows and use fans to reduce humidity, but keep them away from any wet electrical parts. If you have a dehumidifier, run it on a dry surface away from water.

Then, inspect the main breaker and individual breakers for signs of damage. If you see any tripped breakers, do not reset them until you know why they tripped. You can also unplug appliances that were in the affected area to reduce the load when power comes back.

When to Call a Professional

It is wise to have an electrician check your system if water got anywhere near your electrical panel, outlets, or wiring. They can test the circuits and replace damaged parts. This is not a job for a homeowner, even if you are handy.

In addition, water damage pros can handle the drying and cleanup of walls, floors, and ceilings. They have the equipment to remove moisture that you cannot see, which helps prevent mold and further damage. If you live in Doral, keep your electrician's number handy for emergencies.

Safety Tips for After a Flood

Never enter a flooded room if the power is on and water is present. If you must walk through water, use a stick to probe for hazards and wear rubber boots. Also, avoid touching any electrical device while standing in water.

If you smell gas or hear a hissing sound, leave the house immediately and call the gas company from outside. Do not flip any switches or use a phone inside. After the flood, have a professional inspect your HVAC system and water heater before using them again.

  • Keep the main breaker off until inspected
  • Use a flashlight instead of candles near water
  • Do not use wet electrical appliances
  • Dry out the area with fans and open windows
  • Hire an electrician for the panel
  • Call water damage pros for cleanup

Frequently asked questions

Can I turn the power back on if only a small area got wet?

Even a small wet area can be risky. If water touched any outlet, switch, or the panel, it is safer to keep the power off. Have an electrician check the affected circuits first. If the water was just on the floor away from electrical parts, you may be okay, but when in doubt, stay safe.

What should I do if my breaker trips when I turn it on?

If a breaker trips immediately, turn it off again and do not reset it. That suggests a short circuit or a damaged appliance. Unplug everything on that circuit and try once more. If it trips again, leave it off and call an electrician to inspect the wiring.

Is it safe to use a generator after water damage?

Generators can be safe if used correctly. Always run them outdoors, away from windows and doors, to avoid carbon monoxide poisoning. Do not plug a generator into a wall outlet unless you have a transfer switch. Keep the generator dry and never operate it in standing water.
