If you are staring at a wet basement or a dripping ceiling, one of your first questions is probably: what is this going to cost? The honest answer is that it depends on the size of the loss, the type of water and how quickly drying starts. Below is a straightforward breakdown of water damage restoration costs in St. Louis, based on current local pricing data and what we see every day on jobs across the metro.
Quick Answer: Average Water Damage Restoration Cost in St. Louis
According to Angi’s St. Louis cost data (updated August 2026), the average water damage restoration project in St. Louis costs about $1,398, with most projects falling between $766 and $2,076. On a square-foot basis, local pricing runs about $3 to $7.50 per square foot. Nationally, Angi reports a higher average of about $3,868, largely because the national figure includes more large-scale losses.
Small clean-water leaks caught early land at the low end. Sewage backups, finished basements and losses that require rebuilding drywall, flooring and cabinets can run into the thousands or tens of thousands.

- Plumbing repair: about $329 to $3,760, billed by a plumber separately from restoration.
What Drives the Price Up or Down
1. Response time
This is the biggest factor you control. Water that is extracted within a few hours usually allows drywall, framing and some flooring to be dried in place. After 24 to 48 hours, materials swell, water wicks higher up the walls and mold can start, which means more tear-out and more rebuild. Our emergency water extraction crews are available 24/7 for that reason.
2. Water category
Clean water from a supply line is the least expensive to handle. Sewer backups and floodwater require protective equipment, removal of porous materials and disinfection. If you are dealing with sewage, see our sewage cleanup page.
3. Size of the affected area
Restoration is priced largely by square footage and the number of drying days. A single bathroom is very different from an entire finished basement.
4. Materials involved
Hardwood, plaster walls, built-in cabinets and finished basements cost more to dry or replace than concrete floors and unfinished walls.
5. Equipment and drying time
Most losses need three to five days of commercial dehumidifiers and air movers. Dense materials like hardwood and plaster can take longer. We check moisture every day so equipment is removed as soon as the structure is dry.
Will Insurance Pay for It?
For sudden, accidental water damage such as a burst pipe, failed water heater or appliance leak, most homeowners policies cover restoration minus your deductible. Sewer backups require a water backup endorsement, and rising floodwater needs a separate flood policy. We bill your insurance company directly and provide the photos, moisture logs and itemized estimate adjusters need. Learn more in our guide to sewer backup coverage in Missouri.
How To Avoid Paying More Than You Should
- Shut off the water source immediately and call for extraction the same day.
- Take photos and video before anything is moved or thrown away.
- Ask for an itemized estimate and daily moisture readings.
- Be wary of companies that push you to sign an assignment of benefits before explaining the scope.
- Choose an IICRC-certified company that dries to documented standards, so hidden moisture does not turn into a mold bill later.

Sewer backups need a backup endorsement, and rising floodwater requires flood insurance. When a claim is covered, restoration companies like ours bill the insurer directly, and you pay your deductible.
How can I keep water damage costs down?
Act fast. Shutting off the water and starting professional extraction within the first few hours limits how far water spreads and how much must be torn out. Photograph everything for insurance, move belongings off wet floors, and avoid running household fans on sewage. Every day of delay adds drying time, material removal and mold risk.
