National ranges from Angi
Source: Angi, flooded basement cleanup cost, 2026 data, updated October 14, 2026. Paraphrased national estimates. Angi's article is about basement cleanup, which is the loss many Spokane requests describe. A single-room supply leak can land lower. Sewage and whole-floor rebuilds can land higher.
| Scope in the Angi article | National range |
| Most flooded basement cleanup projects | $2,000 to $7,000, average about $4,000 |
| Clean water | $1,500 to $3,500 |
| Gray water from appliances or sinks | $3,000 to $7,000 |
| Sewage or heavily contaminated water | $7,000 to $15,000 |
| Mold remediation listed as an add-on | $500 to $6,000 |
What moves a bid
How dirty the water is, how long materials stayed wet, how much drywall and flooring has to come out, and whether the source is already stopped. A wet ceiling under a burst line on the floor above is a different job from two feet of sewage in a finished basement. Access matters: an open basement is not a tight crawl space. Permits, when walls are opened and rebuilt, are a separate line. We do not pull them.
How policies usually sort the water
Insurance.com's water damage claims explainer states the usual split: sudden and accidental water damage, such as a burst pipe, can be a homeowners claim, and overland flooding is not. Angi's basement article describes the same line for basements, including groundwater and the optional sewer-backup endorsement. Your policy controls. The table is a reading aid, not a coverage opinion.
General patterns reported by Insurance.com and Angi's 2026 basement article. This is not a determination of coverage for any policy.
| What happened | How a standard homeowners policy often treats it |
| Burst supply line, sudden | Often covered, minus the deductible, if the policy says so |
| Appliance supply line that lets go | Often treated as a sudden discharge |
| Slow leak that went on for weeks | Often excluded as maintenance or repeated seepage |
| Sewer or drain backup | Often excluded unless a backup endorsement was added |
| Groundwater through a wall or floor | Often excluded |
| River water, surface water, or other overland flood | Not a standard homeowners loss. Flood insurance is a separate policy |
Flood insurance, through the National Flood Insurance Program or a private carrier, is a different contract from a homeowners policy. FloodSmart is the NFIP's public explanation of that product. Premiums depend on the property. This page does not quote them. Photograph what you can safely see, keep notes on when you first noticed the water, and talk to your insurer about what they want saved before tear-out. We do not file the claim for you.
Before you hire
- Ask what the price includes: extraction, drying, tear-out, and rebuild, or only some of those.
- Ask what category of water they are treating.
- Ask who pulls a permit if walls or plumbing are opened. The city or county for that address decides whether one is required.
- If the work includes construction, ask for the Washington contractor registration number and confirm it on the L&I verify tool. Contractor registration is covered by RCW 18.27. We do not screen contractors.
