What Is Not Covered Under Flood Insurance?

Last updated October 31, 2026

The short answer

Damage from Preventable Moisture and Mold

Flood insurance is designed for sudden, accidental flooding. It generally does not cover damage from long-term moisture issues you could have stopped. If a slow leak from a pipe or a foundation seepage leads to mold, that mold damage is likely excluded. The policy expects you to take reasonable steps to dry out your home quickly after water intrusion.

This exclusion highlights why immediate action is vital after any water event. You must mitigate further damage to protect your property and any potential claim. This means removing water, drying the area, and addressing humidity. In regions with wet seasons, keeping indoor humidity controlled is especially important to prevent secondary damage.

Living Expenses and External Property

If a flood forces you to leave your home, standard flood insurance does not pay for additional living expenses. Costs for a hotel, restaurant meals, or temporary rentals are your responsibility. This is a key difference from many homeowners insurance policies, which often include this coverage for other types of disasters.

Coverage also stops at the building's exterior walls for your belongings. Items left outside are not covered. This includes patio furniture, grills, plants, and decorative items in your yard. Landscaping features like trees, shrubs, and soil damaged by floodwater are also excluded from reimbursement under a typical policy.

  • Additional living expenses (ALE) or loss of use
  • Swimming pools and hot tubs
  • Fences, patios, and decks
  • Lawns, plants, and trees
  • Cars and other vehicles (covered by auto insurance)
  • Currency, precious metals, and valuable papers

Sewer Backups and Earth Movement

A common point of confusion is sewer or drain backup. Flood insurance does not cover damage if water backs up through a sewer or drain unless the backup is directly caused by the flood. A separate endorsement on your homeowners policy is often needed for general sewer backup coverage.

Damage from earth movement, even if triggered by floodwater, is excluded. This includes landslides, mudslides, and sinkholes. If saturated ground causes your foundation to shift or crack, that structural damage likely falls outside the flood policy's scope. These events require specialized insurance coverage.

What Happens After the Initial Flood

Coverage focuses on direct physical damage from the flood. Problems that develop later may not be included. For example, if flood-damaged materials are not properly removed and dried, resulting rot or insect infestation is not covered. The policy is for the immediate impact of the water, not for subsequent deterioration you could have prevented.

This is why professional water damage mitigation is critical. Local water damage pros follow industry standards for drying and cleaning, which helps prevent secondary issues. Their documentation of the damage and the drying process can also be essential for your insurance claim, showing you took appropriate action.

Financial Limits on Certain Items

Even for covered items, there are often sub-limits. Your policy has a total coverage cap, but it may further limit payouts for specific high-value categories. For instance, there are usually lower limits for valuables like art, collectibles, or furs. Cash and similar items are typically excluded entirely, as listed in the bullet points.

Understanding these limits before a flood is crucial. Review your policy's declarations page to see the maximum amounts for the building and contents, as well as any special sub-limits. This helps you know what level of financial protection you truly have and whether you need additional coverage.

  • Artwork, collectibles, and rare items
  • Furs and jewelry
  • Stockpiled inventory for a home business
  • Items in a basement (special rules apply)
  • Decks, patios, and other external structures

Frequently asked questions

Does flood insurance cover a leaking water heater?

No, flood insurance does not cover water damage from internal home systems like a leaking appliance or burst pipe. That type of damage is typically covered by a standard homeowners insurance policy, not a flood policy. A flood must involve water from an external source covering normally dry land.

Is mold from a flood covered?

Mold or mildew damage is usually not covered if you could have prevented it. The policy expects you to dry your home promptly after the flood. If you take immediate action but mold still develops from the initial floodwater, some remediation costs might be considered. Documentation of your mitigation efforts is key.

What should I do first after flood damage?

First, ensure the area is safe from electrical hazards. Then, document all damage with photos and videos for your claim. Contact your insurance company to start the claims process. Next, you should begin water removal and drying to prevent further damage, as delaying can lead to uncovered losses like mold.
