What is the difference between flood insurance and homeowners insurance?
Homeowners insurance generally excludes flood. Flood insurance comes from a separate endorsement, a private policy, or the National Flood Insurance Program. In Maryland, insurers are required to offer a flood or water-backup endorsement, but buying it is optional.
The NFIP policy has a 30-day waiting period before it covers a new or changed flood claim. If you are in or near a mapped floodplain, flood insurance is not optional; most mortgage lenders require it as a condition of the loan. If you are outside the mapped zone, your lender may not require it, but a location that floods stays at risk regardless of the official map.
Talk to your insurer and an insurance agent who knows this area. The person who knows your property and your risk is in the best position to advise whether separate flood insurance makes sense for you.
Does the county map show all the places that flood?
No. Prince George's County reports that most flooding in the past decade came from flash flooding in heavy storms, often outside mapped floodplains. The FEMA flood map is updated infrequently, and flood risk is not limited to the lines drawn on it.
If your property has flooded even once, you are at risk for it again. The grading, the nearby creek, the downspouts and the drainage system that caused the first flood are still there. Photograph the high-water line and ask your neighbors whether their yards have flooded in past storms.
A property that is outside the mapped floodplain can still be vulnerable to a creek that overflows or to low-lying terrain that catches runoff from a storm. Flood risk and mapped flood zone are not the same thing.
What makes flood damage harder to fix than other water damage?
The contamination. Flood water carries silt, salt, sediment, oils and organics that cannot be cleaned out of porous materials. Carpet, carpet pad, insulation and particleboard are almost always removed rather than dried. Hard surfaces are cleaned, but the cost and the timeline are longer because of the cleaning step.
Mold can also grow faster in flood-damaged materials because the sediment and contaminants feed mold growth. Drying speed matters even more after a flood. Any delay in extraction and drying lets contamination seep deeper into framing and supporting materials.
Your insurance record should include the photograph of the tide line, the list of every material removed, the cleaned and dried areas, and the final readings proving the structure is dry. These details shape the cost and the claim approval.
Can anything be saved after a flood?
Yes. Hard surfaces, framing and structural materials can be cleaned and dried. Drywall at or above the tide line may be saveable if it is cleaned immediately and dried thoroughly. Insulation in walls below the tide line is usually removed because it is porous and holds contaminated water.
Mementos, photographs and irreplaceable items are the first things to move to high ground if flooding is forecast. Important documents and valuables should be in a waterproof container. Anything that gets wet and is worth keeping should be addressed in the first few hours while the water is still visible.
The decision about what is salvageable is made from the category of the water and the materials involved. If the flood was fresh water from a broken creek, more may be salvageable than if it was tidal salt water or sewage-contaminated water.
How much does flood cleanup cost?
The size of the area affected, the depth of the water, how much material has to be removed, the level of contamination, and how many drying days the readings require all move the price. Nothing is charged before you have the estimate in writing and have approved it.
A basement that took water to mid-wall with silt and sediment is a significantly different job from a basement with a couple inches of fresh water. The number of materials that have to be removed, the cleaning that has to happen, and the drying time all affect the cost.
Get the estimate in writing before work starts. Document the flood with your own photographs and make a list of what was in the space so you have a record for your insurer. The scope and price are confirmed on site, and you do not pay until you approve it.
