A homeowners policy often covers sudden and accidental water damage, like a burst pipe, and usually does not cover long-term leaks, flood or sewer and drain backup unless an endorsement was added. Flood is a separate policy through FEMA's NFIP or a private insurer. Your insurer decides coverage under your own policy.
Key takeaways
- Water damage insurance depends on where the water came from: a pipe or appliance inside the house, rain coming through a storm-damaged opening, or surface water such as rising rivers, canals and storm surge.
- A standard homeowners policy often covers sudden and accidental interior water damage and usually excludes flood and, unless endorsed, sewer or drain backup and long-term leaks.
- Flood insurance is a separate policy, through FEMA's National Flood Insurance Program or a private insurer, and generally carries a waiting period of about 30 days, so it cannot be bought on the way to a storm.
- Florida hurricane claims have their own deductible structure, so check your policy for a separate hurricane deductible; this page states no percentage.
- A restoration crew can document damage with photos and moisture readings for a claim, but never decides coverage and cannot promise what an insurer will pay.
What is the basic difference between flood and homeowners insurance?
Homeowners insurance covers a defined list of sudden perils to the house and belongings and typically excludes flood. Flood insurance covers direct loss from surface water, such as rising rivers, canals, heavy rain pooling on the ground and storm surge, through the NFIP or a private insurer. They are separate policies with separate claims.
Think of the two as answering different questions. Homeowners coverage asks whether the damage came from a covered peril such as a burst pipe or fire. Flood coverage asks whether surface water entered the building from outside. A single bad storm can trigger both questions at once, and the answer to each is decided by a different policy.
Florida adds a layer on top. Hurricane claims have their own deductible structure, so check your policy for a separate hurricane deductible and ask your agent how it is triggered. This page gives no percentage because policies differ.
Neither policy is described here as a guarantee. What follows is the general pattern for a typical American policy, and the actual wording in your own policy, endorsements and declarations page controls.
Which kinds of water damage does each policy usually cover?
Sudden interior leaks, such as a burst supply line or a failed appliance hose, are commonly covered by a homeowners policy. Flood, storm surge and rising canal or river water are not, and sewer or drain backup usually needs an endorsement. Slow leaks over time are often excluded.
The table lays out the general pattern. It is not a promise about any policy, and exclusions, limits and deductibles vary, so the policy language and your insurer's decision are what count.
| Source of water | Homeowners policy, typically | Flood policy, typically |
|---|---|---|
| Burst pipe or supply line (sudden) | Often covered as sudden and accidental | Not applicable |
| Appliance or water heater failure (sudden) | Often covered; the failed item is usually not | Not applicable |
| Slow, repeated or long-term leak | Often excluded as gradual damage | Not applicable |
| A/C condensate overflow | Depends on whether it was sudden or ongoing; the insurer decides | Not applicable |
| Rain through a roof or window opening | Depends on policy wording and how the opening was created | Not applicable |
| Rising river, canal or lagoon water | Excluded as flood | Covered if the policy applies |
| Storm surge and tidal flooding | Excluded as flood | Covered if the policy applies |
| Heavy rain pooling and entering at ground level | Often treated as flood | Covered if the policy applies |
| Sewer or drain backup | Usually excluded unless an endorsement was added | Often not covered |
Why does it matter where the water came from?
The source decides which policy the claim goes under, what the insurer asks you to prove, and how the water is classed for cleanup. Flood and sewage are Category 3 and need removal of porous materials. Documenting the source early, with photos and dates, protects you whichever way coverage is decided.
Imagine one storm in Port St. Lucie that brings roof leaks, a flooded driveway and a backed-up drain. The roof water may fall under one policy question, the surface water under another and the drain under a third. Mixing them in a single description makes a claim harder to sort out.
Keep the account factual. Write down when you first noticed the water, where you saw it first, how it was entering and what you did to stop it. Do not guess at the cause in writing; leave that to the insurer's adjuster and trained trades, and describe what you saw.
For the local picture of how flood water arrives from rivers, canals and the lagoon, see canal, river and lagoon flooding in St. Lucie and Martin counties, and for storm water through the building envelope see hurricane and tropical storm water damage on the Treasure Coast.
How does flood insurance work, and why is the waiting period a problem?
Flood insurance is sold through FEMA's National Flood Insurance Program or by private insurers, and generally has a waiting period of about 30 days before coverage starts. Buying after a storm is named is usually too late for that storm. City permit guidance notes that many properties sit in FEMA Special Flood Hazard Areas.
The waiting period means flood insurance has to be in place well before any particular storm. Lenders can require it for properties in high-risk mapped areas, and many owners outside those areas carry it anyway because surface water can reach homes that have never flooded before.
This page names no flood-zone letter. Zone designations change, and what applies is set by the exact lot and the current map, so check your own address through the city, the county or FloodSmart.gov rather than relying on a neighbour's experience.
On the Treasure Coast, flat land, canals, the St. Lucie River and the Indian River Lagoon make surface water a realistic concern for many addresses. News reports of 19 September 2024 describe heavy rain flooding Port St. Lucie roads, and reports from October 2024 describe more flooding in St. Lucie County ahead of Tropical Storm Milton. They do not say what any policy covered.
What if one storm causes both wind-driven rain and flooding?
One storm can create several kinds of water damage, and each is sorted by source. Rain through a failed roof or window opening, surface water at ground level and a drain backup may be handled under different policies and deductibles. Describe each wet area separately and let your insurer sort the cause.
Tropical systems on this coast often bring all of it together. Frances and Jeanne in 2004 are the storms local history points to, and the rain from Hurricane Ian in 2022 is remembered locally for canal discharges and pooled water in Palm City. Those events show why homeowners here talk about flood coverage and hurricane deductibles in the same breath.
Separate the damage in your notes. Water that came through the roof or around a window is one account, water that rose from the yard or street into the slab-level rooms is another, and a toilet or floor drain that overflowed is a third. A moisture map from a crew helps because it shows which rooms are wet and where the water seems to have entered, though it does not decide the cause for your insurer.
If part of the house is unsafe or the roof is open, a crew can tarp or board up the opening and clean up inside, but roof replacement and plumbing repair go to the right licensed trades. Keep the invoice for any temporary protection, because your insurer may ask for it.
What should I document and do right after water gets in?
Stop the water if you safely can, take photos and video before anything is moved, and call your insurer early. Keep damaged items until the insurer says otherwise, and keep receipts for emergency steps. A crew can add moisture readings and photos you can share, though coverage is decided by your insurer.
Start with safety: shut the water at the main valve, stay out of standing water near outlets and switch power off to the area only if the panel is dry and safe to reach. Then document. Wide shots show the room, close shots show the damage and the source, and a short video that walks through each space helps an adjuster follow it.
Call your insurer early, and ask what they want before you throw anything away. Emergency steps that limit further damage, such as extracting water and starting drying, are normally something an insurer expects you to take, but ask how your policy treats them. A crew can give you readings and photos for your claim, and the emergency-stage price is explained and approved before work starts, with repairs after drying quoted separately.
Keep a log of calls: date, who you spoke to and what was said. If a claim is delayed or disputed, the state's insurance regulators handle consumer complaints, so know that route exists. Do not rely on any restoration company to promise a result with an insurer, and be wary of anyone who does.
- Photograph and video every wet area, the source and the contents before moving them
- Write down the date and time you noticed the water and how it was entering
- Call your insurer early and ask about their requirements for mitigation and for keeping damaged items
- Keep receipts for emergency work and any temporary housing
- Keep a log of every call and the name of the person you spoke to
How do drying time and mold affect an insurance claim?
Prompt drying reduces damage and mold risk, and EPA advises drying water-damaged materials within 24 to 48 hours as a guideline, not a deadline. Mold may have grown even in materials that were later dried. Many policies limit mold coverage, so read yours and report visible growth early.
Delay can make a loss larger and can raise questions about whether the owner acted promptly. Slow-moving water, like a condensate leak or a hidden slab leak, is also a coverage question because policies often draw a line between sudden damage and long-term seepage. Read the A/C condensate leaks guide for how that gradual-versus-sudden line tends to show up in practice.
If mold shows up, remember Florida licenses mold-related services through DBPR: assessors and remediators are separate licences, and Florida's rules apply to areas above about 10 square feet. An assessor may not perform or offer remediation on a structure the assessor assessed in the past 12 months, so the person who tests should not be the person who sells the cleanup. See Florida mold assessor and remediator licences explained for more.
Repairs after drying, such as drywall, flooring and paint, are separate from the emergency work, and rebuilding after water damage generally needs a Florida-licensed contractor you can look up on DBPR's licence search.
Frequently asked questions
Does homeowners insurance cover a burst pipe in Florida?
Often yes for the sudden water damage, but not always, and the pipe repair itself is usually not covered. Policies differ on limits, deductibles and exclusions for long-term leaks. Photograph the damage, stop the water, and ask your insurer how your policy treats it.
Is rain coming through a hurricane-damaged roof flood damage?
Usually not. Flood generally means surface water entering from outside, not rain entering through the roof. How a roof opening was created can matter to the claim, so the policy wording and your insurer's decision control the outcome.
Can I buy flood insurance when a storm is approaching?
You can usually apply, but coverage generally does not start for about 30 days, so it will not apply to a storm already approaching. Talk to an agent well before hurricane season, which runs 1 June to 30 November.
Will a restoration company handle my insurance claim?
The crew can document damage with photos and moisture readings, and you can share them with your insurer. Coverage and payment are decided by your insurer under your own policy, and no restoration company should promise an insurance outcome.
Does flood insurance cover a sewer or septic backup?
Often no. Backup from a sewer, drain or septic system is a separate question from surface flood water, and it is usually handled by a homeowners endorsement if one was added. Read the exact wording of both policies and ask your agent.
