The first day after a leak, flood, or roof failure decides most of what happens next: how much of your home can be saved, how big the bill gets, and whether mold becomes part of the story. In Florida the clock runs faster than almost anywhere else, because warm air and 70 to 90 percent outdoor humidity keep materials wet and let mold begin in as little as 24 to 48 hours. This guide walks through what to do, in order, hour by hour, and what to leave alone.
Key takeaways
- Safety comes first: electricity and water do not mix, and floodwater or sewage is contaminated.
- Stop the source, then get standing water out. Every hour of delay pushes water deeper into drywall, subfloor, and slab.
- Photograph and video everything before you clean. Your insurance claim depends on it.
- Do not rely on fans and open windows to dry a Florida home. Controlled dehumidification is what actually removes the moisture.
- Call a professional within the first few hours for anything beyond a small, clean spill.
Step 1: Make the space safe
Before you touch anything wet, check for hazards. Water conducts electricity, and a wet outlet, appliance, or extension cord can be lethal.
- If water is touching outlets, appliances, or the electrical panel, do not walk through it. Switch off power at the main breaker only if you can reach it while standing on a dry surface. If you cannot, call your utility or an electrician.
- If the ceiling is sagging or bulging with trapped water, keep everyone out from underneath it. Saturated drywall can collapse without warning.
- If the water came from outside (a storm, canal overflow, or river), assume it is contaminated. Wear waterproof boots and gloves, and keep children and pets away.
- If there is any danger to life, call 911 first.
Step 2: Stop the water at the source
Water damage gets worse for as long as water keeps arriving. Find the source and cut it off as fast as you safely can.
| Source | What to do right now |
|---|---|
| Burst pipe, supply line, or appliance hose | Close the main water shutoff (usually near the street meter, at the garage wall, or where the main line enters the house). Then open a faucet at the lowest point to drain the lines. See burst pipe water damage. |
| Water heater failure | Shut off the cold-water inlet valve and switch off the power or gas to the heater. |
| AC drain or air handler overflow | Turn the air conditioner off at the thermostat and the breaker so it stops producing condensate. See AC leak water damage. |
| Roof leak | Move belongings, place buckets, and arrange emergency tarping. A tarp keeps the next storm from making it worse. See roof leak water damage. |
| Toilet or drain backup | Stop using all plumbing fixtures. Do not flush. This can be Category 3 water. See sewage backup cleanup. |
| Storm or flood water entering the house | You cannot stop this yourself. Move to higher ground, stay out of the water, and wait for the all-clear before re-entering. |
Step 3: Identify the type of water
Restoration professionals classify water into three categories, and the category decides what can be saved and how the work is done. You do not need to be an expert, but you should know which side of the line you are on. The full explanation is in our guide to water damage categories and classes.
| Category | Typical sources | What it means for you |
|---|---|---|
| 1: Clean | Broken supply line, tub or sink overflow, rain entering through a roof | Carpet and many materials can often be saved if dried within about 24 to 48 hours. |
| 2: Gray | Washing machine or dishwasher discharge, toilet overflow without feces, aged Category 1 water | Some contamination. Carpet pad is usually removed; other materials are evaluated case by case. |
| 3: Black | Sewage, river or seawater flooding, standing water that has been left for days | Grossly contaminated. Porous materials (carpet, pad, drywall, insulation) are removed. Requires protective equipment and disinfection. |
If you are unsure, treat it as the more serious category. Clean water becomes gray water in roughly two days in Florida heat, so delay changes the answer.
Step 4: Document everything before you clean
This step feels like a distraction when your floor is wet, but it is the single most useful thing you can do for an insurance claim. Adjusters want to see what the damage looked like before any cleanup. Our Florida insurance claim guide explains how claims work in detail.
- Take wide photos of every affected room, then close-ups of the source of the water, the waterline on walls, and each damaged item.
- Record a slow video walkthrough narrating what you see: the room, what happened, and when you noticed it.
- Write down the time you discovered the problem and what you did about it, including the time you shut off the water.
- Keep damaged items until the adjuster has seen them, unless they are unsafe or contaminated.
- Save every receipt for emergency work, equipment rentals, hotel stays, and replacement of essentials.
Step 5: Remove standing water and protect what you can
For a very small, clean spill, towels and a wet vacuum may be enough. For anything larger, professional water extraction removes water from carpet, pad, and the subfloor far more completely than household tools can.
Things you can safely do while you wait
- Lift furniture off wet carpet and place foil or plastic under the legs to prevent staining and rust.
- Remove rugs, loose items, and anything valuable or sentimental from the wet area to a dry room.
- Pull books, photographs, and documents out of water and spread or freeze them; a professional can often save papers that are dried or frozen quickly.
- Open interior cabinet doors and drawers to let air reach wet surfaces, but do not tear out walls or floors yourself.
- Wear gloves, boots, and a mask in any area that may be contaminated.
Step 6: Call a restoration company early
Make the call within the first few hours, not the next morning. A professional crew brings truck-mounted or portable extractors, moisture meters and thermal cameras to find water you cannot see, and low-grain refrigerant (LGR) dehumidifiers and air movers to dry the structure. Read about how emergency water damage restoration works, or call (305) 789-7628 to reach a crew now.
You should call a professional if any of the following is true:
- Standing water covers more than a small area or has soaked carpet, pad, or baseboards
- The water is gray or black, or you do not know where it came from
- A ceiling is stained, sagging, or dripping
- Water has been present for more than 24 hours
- The water came through walls, from above, or from under a slab
- Someone in the home has asthma, allergies, or a weakened immune system
Why Florida homes dry differently
Florida water damage has a few quirks that generic advice ignores.
- Humidity works against you. When outdoor air is already near saturation, opening windows adds moisture instead of removing it. Professional drying uses a closed system with dehumidifiers so the air can actually accept moisture from wet materials.
- Slabs spread water sideways. Most Florida homes sit on concrete slabs. Water tends to travel across the whole floor and wick up baseboards and the bottom of walls rather than pooling in one spot. See wet carpet and floor drying.
- Block walls hide moisture. Concrete block homes with interior furring strips and drywall can hold water in the wall cavity long after the floor looks dry.
- Power outages change the plan. After a hurricane, the AC may be off for days, and indoor humidity climbs quickly. Start dehumidifying as soon as power or a generator allows. See our hurricane season prep guide.
- Condos involve other people. In a condo or apartment, tell building management and neighbors below right away. See condo and high-rise water damage.
- Vacation homes and rentals. A leak in a home that is empty between guests can run for days. Turn off the water main when you leave.
The 24-hour timeline at a glance
| When | What should be happening |
|---|---|
| Hour 0 to 1 | Make the area safe, stop the water source, call 911 if there is danger, call a restoration company. |
| Hours 1 to 4 | Photograph and video the damage, move valuables, begin removing standing water, crew arrives and begins extraction and moisture mapping. |
| Hours 4 to 12 | Wet carpet pad and saturated materials removed, drying equipment set, insurance company notified. |
| Hours 12 to 24 | Equipment running with daily monitoring, affected areas isolated, humidity controlled to prevent mold. |
| After 24 to 48 hours | Mold risk rises sharply on anything still wet. Materials that were Category 1 may now be treated as Category 2. See the Florida mold timeline. |
Common mistakes that raise the cost
- Waiting until morning. In Florida heat, a few hours can be the difference between drying drywall and replacing it.
- Running the AC to dry the house. If the ductwork or air handler is wet or contaminated, the system can spread moisture and spores through the home.
- Using household fans only. Fans move wet air around but do not remove moisture from the building.
- Leaving wet carpet pad in place. Pad holds water like a sponge and rarely dries fast enough in humid conditions.
- Cleaning first, photographing second. You cannot document what you have already thrown away.
- Assuming it is over when the surface looks dry. Water often remains inside walls, under flooring, and in insulation. Moisture readings, not appearance, tell you when drying is done.
- Not calling the insurance company. Most policies require prompt notice and reasonable steps to prevent further damage.
What a professional does when they arrive
Knowing what to expect helps you judge whether a company is doing the job properly. A thorough response typically includes: a safety check and source confirmation; identification of the water category; extraction of standing water; moisture mapping with meters and thermal imaging; removal of materials that cannot be saved; placement of air movers and dehumidifiers sized to the space; and daily readings until each material reaches its dry standard. You should receive photos, moisture logs, and a written scope of work. If you want to understand how drying is measured, see structural drying and dehumidification.

Frequently asked questions
How long do I have before mold starts growing after water damage?
In warm, humid Florida conditions mold can begin growing in 24 to 48 hours on wet drywall, wood, and carpet. That is why extraction and drying should start the same day. See our mold timeline guide.
Should I turn the power off if my house is wet?
If water is near outlets, appliances, or the panel, yes, but only if you can reach the breaker without standing in water. If you cannot do that safely, call your utility or an electrician and stay out of the water.
Can I dry my house with fans and a dehumidifier from the hardware store?
For a small, clean spill on a hard surface, sometimes. For anything that has soaked carpet, drywall, or subfloor, consumer equipment usually cannot remove moisture fast enough in Florida humidity, and hidden moisture is easy to miss without meters.
Do I need to wait for the insurance adjuster before starting cleanup?
No. Most policies require you to take reasonable steps to prevent further damage. Photograph the damage first, keep receipts, and start extraction and drying. See the insurance claim guide.
What if the water came from a neighbor’s unit in my condo?
Document the damage, notify building management and the neighbor, and call your own insurer. Your association’s governing documents and both owners’ policies determine who pays. See condo and high-rise water damage.
How much does emergency water removal cost?
It depends on the size of the affected area, the water category, and materials involved. Small clean-water jobs can run in the low four figures, while flood and sewage jobs cost more. Use the cost calculator for a range based on your ZIP code.
