The short answer
Right now: Stay out until the fire department or a building official says it is safe. Floodwater can carry sewage and hide live wiring. Switch off the breaker only if you can reach it without standing in water; otherwise call the utility. Smell gas? Leave, then call the gas utility or 911 from outside.
Flood damage restoration is cleaning and drying a building after water rose from outside and came in at ground level. IICRC S500 treats floodwater as Category 3, grossly contaminated, so porous material it soaked is generally removed rather than dried.
FEMA puts the insurance side plainly: “Most homeowners insurance does not cover flood damage.” The claim goes to a separate NFIP or private flood policy.
What decides a flood job and a flood claim?
Rain through a storm-damaged roof is a homeowners peril. Water that rose off the ground is a flood, and homeowners policies exclude it.
Through the National Flood Insurance Program, run by FEMA, or a private flood insurer.
A new NFIP policy does not start the day you buy it, with narrow exceptions, so it cannot be bought against a forecast.
Porous material it soaked comes out; it is not dried in place.
An NFIP policy covers them as two parts with two limits, and restricts what it pays for in a basement.
Soaked masonry, slabs and below-grade walls give water back slowly, and humid outside air works against you.

Was it a flood or a water loss?
The answer decides which policy, which adjuster and which claim number you deal with, and the building itself can show it.
A horizontal mark at the same height across every room is the signature of rising water.
Floodwater carries the ground with it. Water from a pipe does not.
Rather than starting at a ceiling and running down.
A burst pipe is yours alone; a flood is the street’s.
Through a basement wall or up a drain, not through a roof or window.
A missing roof section or a broken window is the other side of the line, and can be a homeowners wind claim. See storm damage restoration.
What should be assessed at a flooded house?
A flood assessment starts with whether the building is safe to enter and still sound, which is not where an ordinary water assessment starts.
Undermined or scoured footings, a slab that moved, and whether the building department has posted the property.
Submerged panels, outlets, furnaces, water heaters and gas appliances are generally replaced rather than dried, and inspected before anything is switched back on.
It sets the drywall cut line and is evidence for the claim.
Nearby sewers, fuel tanks, farms or industry change the handling.
A basement dries differently and is insured differently.
Fiberglass and cellulose that took floodwater come out, so the cavity is opened either way.
After a regional flood the outside air is saturated too, which slows dehumidification.
In a house built before 1978, tested before demolition, not after.
What happens after a flood, in order
Structural, electrical and gas hazards first. Nothing about drying matters if the floor is not sound.
Photos and video of every room, the water line on each wall, the outside and the contents, before anything is pumped or moved. Take your own set as well as the contractor’s.
Standing water out, then the silt and debris it left. Pumping a basement too fast can harm the walls while saturated soil still presses on them, so this is a judgment call, not a race.
Carpet and pad, wet insulation, drywall cut above the water line, particleboard cabinets, and soaked ceiling below an affected floor. On a Category 3 loss this is the main work.
Framing, masonry, slabs and hard surfaces are cleaned and decontaminated before they are dried. That is the order the standard works in.
Dehumidifiers and air movers sized to a larger, wetter space than a household leak, with wall cavities open so the inside of the assembly can dry.
Daily readings per material and location, against a dry standard from unaffected parts of the house. Masonry and concrete will be the last to reach it. See structural drying.
Final readings recorded and equipment out before the rebuild starts. Reconstruction is a separate scope and a separate bid.
Flood or not flood: where does the claim go?
Policies define flood more narrowly than everyday speech: a temporary inundation of normally dry land, affecting more than your property alone. This is the practical version. Your own policy wording governs.
| What happened | Which policy it points to |
|---|---|
| Rising water from outside | A river, creek, storm surge, overwhelmed drains, or water sheeting off saturated ground. Excluded from homeowners policies. This is what a flood policy is for. |
| Wind-driven rain through a storm opening | The storm tore off roof covering or broke a window and rain came through. Can be covered by homeowners as wind damage. Same storm, different peril, different policy. |
| Groundwater through a basement wall or slab | Can be treated as flood or as seepage rather than a sudden discharge. Disputes gather here, so read your own exclusions before you need them. |
| Sewer or drain backup | Can be excluded from both homeowners and flood policies unless a backup endorsement was added. See sewage cleanup. |
| Burst pipe or failed appliance | A sudden, accidental discharge and a homeowners matter, not flood. See water damage restoration. |
| A storm that did all of it | Two adjusters may visit. Record which damage sits at the high-water line and which sits below the roof opening, because the two claims split along that boundary. |
What belongs in the written scope
Ask for these in writing before demolition starts. On a flood job they are also what the flood adjuster will compare.
The scope names the Category and what it means for removal.
The drywall cut height per room, and every material removed rather than cleaned.
Where barriers go and what the crew wears while contaminated material is removed.
The target for framing, masonry and slab, the daily log, and how the company shows the area is clean and dry before walls close.
What moves the price
A flood job is priced like a Category 3 loss with a demolition scope attached: less drying, more removal and disposal, and a longer tail on below-grade materials.
| Factor | Why it changes the number |
|---|---|
| Height of the water | The largest driver. Drywall is cut above the water line, so four inches and four feet are very different demolition scopes. |
| Removal vs. drying | Category 3 makes removal the default for porous material. That moves cost from equipment days toward labor, disposal and, later, the rebuild. |
| Disposal | Contaminated material has different disposal rules from ordinary debris, and after a regional flood local disposal capacity becomes a limit of its own. |
| Below-grade area | Basements and crawl spaces hold water in masonry and soil and dry slowest. |
| Mechanical and electrical replacement | Submerged furnaces, water heaters, air handlers, panels and outlets are generally replaced, not restored. |
| Outdoor humidity | When the outside air is saturated, dehumidifiers work longer for the same result. |
| Contents | Cleaning, pack-out, storage and disposal, priced separately from the structure and insured separately under the NFIP. |
| Demand after a declared disaster | Labor and materials tighten regionally after a large flood, and door-knockers arrive. See avoiding restoration scams. |
| Floodplain rules in the rebuild | Raising mechanicals, flood-resistant materials or elevating the structure can be required by the local floodplain ordinance once repairs pass a threshold. |
HyreRestore publishes no average flood restoration price. Water height, how much of the house came out, disposal rules and post-disaster demand move the number too far for one figure to help.
How does a flood claim work?
This is how flood cover operates in the United States, not what your policy says. Your declarations page, your flood policy and your insurer decide the answer.
| Question | How the claim treats it |
|---|---|
| Homeowners policies | Exclude flood. FEMA: “Most homeowners insurance does not cover flood damage.” That is why a separate program exists. |
| The National Flood Insurance Program | Run by FEMA and sold through participating insurers and agents, in communities that take part in the program. |
| Private flood insurance | An alternative or an excess layer over an NFIP policy. Terms vary by insurer, so compare the wording rather than assuming it matches the NFIP. |
| The waiting period | FEMA: “Plan ahead as there is typically a 30-day waiting period for an NFIP policy to go into effect, unless the coverage is mandated, it is purchased as required by a government backed lender, or is related to a community flood map change.” |
| Building and contents are separate | Two parts, two limits, and you can hold one without the other. Renters can insure contents alone. If you never bought contents cover, the furniture is not in the claim. |
| Replacement cost vs. ACV | The Insurance Information Institute: “Buildings are covered for replacement cost, but coverage for personal property is available on an actual cash value basis only.” See ACV versus RCV. |
| Basements are restricted | NFIP cover in basements and other below-grade areas is limited, especially for finishes and belongings. A finished basement can be the largest gap between what was lost and what is paid. |
| Additional living expenses | Standard NFIP policies do not include temporary housing, which surprises people who expect it from their homeowners policy. Some private flood policies differ. |
| Proof of loss | Flood claims have their own paperwork and deadlines. Ask the adjuster for the proof-of-loss deadline in writing at the first visit. |
| Two claims from one storm | Wind on the homeowners policy, rising water on the flood policy. Keep the evidence separate as you gather it. |
Coverage is decided by your own policy and the peril, not by what is typical. Read the declarations page, and where the answer matters, put the question to your insurer in writing.
Check your flood position before the season
Two questions answer it. Does my homeowners policy exclude flood? It does. Do I hold a separate flood policy with both building and contents cover? If not, the 30-day wait means that decision belongs to a quiet week, not the week of a forecast.
What to ask before you sign
What to have ready for the adjuster and the crew
Photos and video of it in every room, taken before anything moved.
Flood and homeowners are different claims.
Water in the street or across the yard, if you have any.
With photos, before anything is thrown out.
Any emergency declaration or evacuation order for your address.
Pumps, hotel, replacement essentials, from the first day.
If one exists for the property.
Where this goes wrong
It does not. People find this out on the day of the loss rather than the day they bought the policy. If you are reading this before anything has happened, now is the useful moment to check.
Under a flood policy, contents are a separate part with their own limit, and the damaged items are the evidence. Photograph, list, and keep them until the adjuster has seen them or released you in writing.
Floodwater in a wall cavity is a contamination problem as well as a moisture one. Insulation that took floodwater comes out. A dry-reading surface over an unopened cavity has not been restored.
Panels, outlets, furnaces, water heaters and appliances that were under water are an electrical and gas safety matter. They are inspected, and generally replaced, before anything is turned back on.
Local floodplain rules can require flood-resistant materials or raised mechanicals once repairs pass a threshold. Finding out after the drywall is up is expensive.
After a declared disaster, the crews that arrive fastest are not always local. Taking a day to check licensing costs nothing once cleanup is running under a limited authorization.

Primary-source research and fact checking
We are a research desk, not a restoration company and not an insurance adjuster.
We read the federal agency guidance, the state insurance statute or the industry standard ourselves, and we publish the rule with the document it came from and the date we read it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. The counts below are taken from the pages on this site.

How this desk works
- Primary sources only. A mold rule comes from the EPA, a flood rule from FEMA and the NFIP, a claim rule from the state insurance statute. We do not cite an article that cites a source.
- Every figure carries its retrieval date. Guidance is revised and statutes are amended. A number without the date it was read cannot be checked.
- Paywalled standards are named, not quoted. IICRC S500 and S520 define the categories and classes of water and mold work. We describe their public structure and say plainly when the controlling text sits behind a purchase.
- Safety before the claim. Electricity near water, sewage, smoke and mold come first on every page where they apply. We explain the work; we do not tell you to do it yourself.
- We do not dry, remediate or rebuild anything, we do not adjust claims, and we take no payment for placement, ranking or a favorable mention.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
