What to Do After Water Damage in a Florida Home — Step-by-Step

Step 1 — Stop the Water Source

If water is still entering the property, stopping the source is the first action. For a supply line failure, toilet overflow, or water heater rupture, locate the shut-off valve for that fixture or the main water shut-off for the property and turn it off. If you do not know where the main shut-off is, your water utility can tell you. In Florida's older housing stock — pre-1960 properties in historic Tampa, St. Petersburg, and South Florida neighborhoods — main shut-offs can be in non-obvious locations. Know where yours is before an event, not during one.

For storm surge, coastal flooding, or heavy rain entry through a roof breach, there is no shut-off. The water stops when the weather stops. In that case, Step 1 is confirming the property is safe to enter. If structural damage is visible, if electrical panels or outlets were submerged, or if there is any doubt about the structural integrity of the building, do not enter until a contractor or building inspector clears it. Tampa Bay and South Florida surge events have produced properties where the electrical system was compromised by saltwater intrusion — treat any surged property as potentially live until it has been assessed.

Step 2 — Assess the Category of Water

The IICRC S500 standard classifies water damage into three categories that determine the restoration protocol. Category 1 is clean water from a supply line, water heater, or appliance overflow. It can be dried in place with prompt equipment deployment and carries the lowest remediation cost. Category 2 is grey water — washing machine overflow, dishwasher discharge, toilet overflow without solid waste. It requires antimicrobial treatment and more conservative material handling. Category 3 is black water: sewer backup, stormwater, floodwater, and storm surge from any Florida coastal waterway. Bay water, canal water, and floodwater entering from outside are all Category 3 regardless of visual appearance. Category 3 requires removal of all porous materials below the waterline — drywall, insulation, and flooring cannot be dried in place because the contamination cannot be extracted from porous substrates.

Step 3 — Document Before Touching Anything

Before moving furniture, extracting water, or touching affected materials, photograph and video everything. Walk through the property and record: the source of the water if visible, the extent of standing water, every room and surface affected, and any visible damage to walls, flooring, cabinets, and fixtures. The timestamp on your phone's camera is the first piece of evidence in your insurance claim. Adjusters use initial documentation to establish the scope of loss at the time of the event. Documentation taken before any mitigation work begins is far more useful than documentation taken after extraction has started.

Note the time you found the water and how long you estimate it had been present. If you were away — seasonal or absentee owners in Florida's second-home markets in Naples, Sarasota, and West Palm Beach are frequently in this position — estimate based on what you can observe: standing water depth, waterlines on walls, and the condition of affected materials. If mold is already visible, photograph it separately. Mold presence changes the scope from water damage restoration to a two-phase process under Florida Statute 468.8411.

Step 4 — Call a Licensed Contractor

Emergency extraction should begin as quickly as possible. The IICRC S500 24-hour mold establishment window starts when water contacts structural materials — not when you call. Every hour of delay with standing water present is an hour of moisture migration into wall assemblies, subfloor structures, and framing. In Florida's wet season, ambient humidity means structural materials that have been wet for more than a few hours are already in mold-growth conditions. A contractor who arrives and extracts standing water within hours of the event is working to prevent a mold problem. A contractor who arrives two days later may be starting one.

When you call, have the following ready: the address and the location of the damage within the property, what you believe the water source is, whether water is still actively entering, how long you estimate the water has been present, and whether mold is visible or suspected. For post-storm events in Pinellas County, Tampa Bay, or South Florida, note that access delays are common during and immediately after major events. A contractor already positioned in your area has an advantage over one travelling across a causeway or through post-storm traffic.

What Not to Do After Water Damage

• Do not use a standard household vacuum to extract standing water. A wet-dry shop vacuum can remove surface water but does not extract moisture from subfloor assemblies, wall cavities, or structural framing. It gives the appearance of drying without achieving the IICRC S500 standard.
• Do not run your HVAC system to dry the property. In Florida's humid climate, running the air conditioning circulates humid air through ductwork and does not dry structural materials. For Category 3 contaminated water events, running HVAC can spread contaminants through the system.
• Do not remove or dispose of affected materials before the contractor assesses them. The contractor's initial scope documentation — including what materials are present before removal — is part of the insurance claim record. Removing materials before the adjuster or contractor documents them creates gaps in the claim.
• Do not assume the property is dry because the surface is dry. In plaster walls, wood frame construction, and pier-and-beam subfloor assemblies common in Florida's older housing stock, structural moisture reads well above the IICRC S500 drying standard even when surfaces appear dry to the touch.
• Do not delay calling your insurance company. Florida Statute 627.70132 sets a one-year deadline for hurricane-related claims. For non-hurricane events, most HO-3 policies require prompt notice of loss. Delay in reporting can affect claim outcomes independent of the statutory deadline.
• Do not hire an unlicensed contractor after a storm event. Post-storm markets in Florida attract unlicensed operators. Verify any contractor's Florida license at myfloridalicense.com before authorising work. A job performed by an unlicensed contractor may not be covered by your insurance and creates liability exposure if a worker is injured on your property.

Insurance — What to Do in the First 48 Hours

Contact your insurance agent or carrier within 24 to 48 hours of discovering water damage. Most HO-3 policies require prompt notice of loss, and delay in reporting can affect claim outcomes. When you contact your insurer, have your policy number ready, a description of the loss, and the documentation you took in Step 3. Ask your agent to confirm: whether the event is covered under your policy, what your deductible is, whether you have a separate hurricane deductible that applies, and what the process is for emergency mitigation authorisation.

For storm surge and flooding from external water sources, a standard HO-3 policy does not cover the loss. Surge and flood require a separate NFIP or private flood policy. If you carry flood insurance, contact your flood insurer separately from your homeowners insurer. The two claims are handled independently. If you do not carry flood insurance and your property was damaged by storm surge, the loss is not covered by a standard homeowners policy — consult a Florida attorney or a public adjuster for your options.

Florida Statute 627.70132 sets a one-year deadline for filing hurricane-related property insurance claims. For Hurricane Helene, that deadline is September 2025. For Hurricane Ian, that deadline was September 2023. If you experienced damage from a named storm and have not filed a claim, contact your insurance agent immediately to confirm what filing options remain under your specific policy. The restoration contractor's documentation package — initial readings, daily moisture logs, and final clearance — is what adjusters use to evaluate and settle the claim. Start that documentation trail at the time of the event.

When Water Damage Becomes a Mold Problem

At Florida's wet season humidity — typically 80 to 90 percent relative humidity from June through October — mold can begin establishing in wet structural materials within 24 hours of a water event. This is not a worst-case scenario; it is the standard condition for a water damage event that goes unaddressed for a day or more in Florida's climate. The specific risk in Florida's older housing stock is moisture that migrates into original plaster walls, wood lathe assemblies, and pier-and-beam subfloor structures and remains at mold-growth conditions well after the surface appears dry. A homeowner who extracts standing water and runs fans has addressed the visible problem. The structural framing inside the wall may stay wet for days longer.

If mold is already visible when you find the water damage, or if the water event is more than 48 to 72 hours old before professional extraction begins, mold assessment under Florida Statute 468.8411 is the right starting point rather than restoration. A licensed Mold Assessor evaluates the property, identifies the species and extent, and writes the protocol. A licensed Mold Remediator carries out the work. An independent licensed assessor conducts clearance testing. The assessor and remediator must be separate entities under Florida law — a company cannot assess and remediate the same job. For properties affected by Hurricane Helene surge in September 2024 that were not professionally dried at the time, this process is almost certainly where you start.
