Water Damage Insurance Claim Calculator

It depends on the source. Common homeowners policy wording covers an accidental discharge or overflow of water from within a plumbing, heating, air conditioning or fire sprinkler system or a household appliance, such as a burst pipe or a failed water heater. The same wording excludes flood and surface water, water that backs up through sewers or drains unless you have a backup endorsement, water below the surface of the ground, and seepage that continues over weeks or months unless it was hidden and unknown to you. Rain that enters through an opening made by wind or hail is treated as storm damage. Your own policy's wording controls.

It describes a water release that happens quickly and unexpectedly, such as a pipe bursting or an appliance hose failing. Policies word it differently; one common form covers an "accidental discharge or overflow of water or steam" from plumbing, heating, air conditioning and fire sprinkler systems and household appliances. The opposite is damage that develops slowly. One common form excludes seepage or leakage over "weeks, months or years" unless it was hidden and unknown to you, and some policies use a fixed test such as 14 days or more.

The ANSI/IICRC S500 Standard for Professional Water Damage Restoration is published by the Institute of Inspection, Cleaning and Restoration Certification. It describes the procedures and precautions for water damage restoration in homes and other buildings, and it sorts water into three categories by contamination: Category 1 (clean), Category 2 (gray) and Category 3 (black). It gives contractors and adjusters a common way to document and scope a water loss.

HomeAdvisor's water damage restoration cost guide, updated June 17, 2026, puts professional water removal and drying at about $3 to $4 per square foot for Category 1 (clean) water, $4 to $6.50 for Category 2 (gray) water and $7 to $7.50 for Category 3 (black) water. Those figures cover cleanup only. Repairs to drywall, flooring, cabinets and contents come on top and depend on your home, so this calculator asks for your contractor's or insurer's repair figure instead of guessing it.

Mitigation is the emergency response: extracting water, drying with air movers and dehumidifiers, removing saturated materials and stopping the spread of damage. Restoration is the rebuild: replacing drywall, flooring, cabinets and finishes to return the property to its condition before the loss. Keep the mitigation invoice and the repair estimate as separate documents when you submit them.

It depends on the cause and your policy. Common homeowners wording excludes mold but covers mold hidden within walls, ceilings or floors that results from an accidental discharge from plumbing, heating, air conditioning, a fire sprinkler system or a household appliance. Some policies cap mold with a sublimit; one policy reviewed by a Florida appeals court capped mold and related damage at $5,000. Mold from long-term leakage is generally excluded. The EPA advises drying water-damaged areas within 24-48 hours to prevent mold growth.

Yes. Common reasons include a finding that the damage was gradual rather than sudden, an excluded source (flood, surface water, groundwater, or sewer backup without an endorsement), damage that grew because mitigation was delayed, or too little documentation of when and how the damage happened. A licensed public adjuster can review a denial against the policy wording.

First, stop the source: shut off the main water valve for a plumbing failure. Second, photograph and video the damage before you move anything. Third, call a water mitigation company as soon as you can; the EPA advises drying water-damaged areas within 24-48 hours to prevent mold growth. Fourth, give your insurer prompt notice and get a claim number. Fifth, keep every receipt for emergency supplies, lodging and mitigation. Quick drying and good records protect the claim.
