Nationally, water damage restoration typically runs between $500 and $6,000 for most residential jobs, with smaller clean-water jobs on the low end and major structural or sewage jobs costing much more. In St. Louis, MO expect similar national ranges; severe black-water gut-and-rebuild jobs can exceed $10,000.
Below you will find clear, plain-language cost ranges and a category-driven guide that explains how clean, gray, and black water change both the work needed and the price you will pay.
Estimate your cost in St. Louis

Labor only. Materials, reconstruction, and mold remediation are extra. Always confirm with an on-site inspection; insurance may cover part or all of this.
Quick overview by water category
Water is classified into three categories. Each category drives different health risks and cleanup steps, which is the main reason costs vary.
Clean water is from a supply line or rain. It is the cheapest to handle because it poses low health risk if addressed quickly. Nationally, small clean-water jobs often cost several hundred to a few thousand dollars.
Gray water contains contaminants from dishwashers, washing machines, or some toilet overflow. It needs faster cleanup and some materials may need removal. Expect higher labor and disposal fees than clean water jobs.
Black water is sewage or floodwater from outside. It is hazardous. Black-water jobs usually require full gutting, special protective gear, disposal of ruined materials, and often structural repairs. These jobs are the most expensive and can exceed ten thousand dollars for major damage.
What drives the cost
Type of water. Clean water can often be dried and sanitized. Black water often requires removal and reconstruction.
Extent of saturation. If only a small area is wet you may only need extraction and drying. If walls, insulation, flooring, and ceiling are soaked you will pay more.
How fast you act. Faster response reduces mold risk and secondary damage, cutting costs.
Access and materials. Jobs that require cutting walls, rip out flooring, or replace insulation increase labor and material costs.
Emergency service and timing. Nights and weekends often cost more.
Detailed cost breakdown
This list gives national ranges so you can budget. Exact prices in St. Louis will depend on the company, the season, and whether your insurer is involved.
- •Inspection and moisture mapping: many companies offer free estimates; emergency inspection or small service call can be $75 to $200 nationally.
- •Water extraction: small jobs $200 to $1,000; larger extraction for several rooms $1,000 to $3,000 nationally.
- •Drying and dehumidification: expect roughly $1.50 to $7 per square foot nationally for drying and monitoring, depending on how many machines and days of equipment rental are needed.
- •Antimicrobial treatment and sanitation: light treatments a few hundred dollars; heavy antimicrobial work can be $500 to $2,000 nationally.
- •Removal and disposal of damaged materials: drywall, insulation, and flooring removal costs vary widely; plan for $500 to $5,000 depending on affected area and whether structural repairs follow.
- •Mold remediation if discovered: small localized mold jobs often run $500 to $3,000; larger mold remediation tied to water damage can be much more.
- •Sewage or black-water cleanup: add considerable cost because of safety protocols and disposal. Small localized sewage cleanups may start around $2,000 nationally. Full gut-and-rebuild jobs can exceed $10,000.
- •Reconstruction and repairs: cosmetic and structural repairs vary by scope. Simple drywall and paint might be a few hundred to a few thousand. Full room rebuilds go higher.
How insurance and timing affect what you pay
If the damage is sudden and accidental many homeowners policies cover restoration costs after your deductible. Floods from outside surface water usually need separate flood insurance.
Call your insurer early and document damage with photos. Most restoration contractors will work with your insurer and provide estimates for claims.
Act fast. The sooner you start extraction and drying, the less secondary damage you will pay to fix later.
How to choose a contractor in St. Louis and lower surprise costs
Look for licensed, insured local companies that offer a written estimate and explain the steps they will take. Ask for references, before and after photos, and whether they handle claims directly with your insurer.
Get at least two written estimates. Compare what is included. A low bid that skips drying mats, moisture monitoring, or disposal can cost you more later.
Ask about guaranteed timelines for equipment on site and moisture targets before they stop drying. This helps avoid hidden follow-up fees.

Frequently asked questions
Will my homeowner insurance cover the cost?
Often yes for sudden accidental water like a burst pipe. Standard policies usually do not cover flood damage from rising water. Contact your insurer quickly and save photos and receipts. Contractors can usually provide documentation for claims.
How fast should I call a restoration company?
Call immediately. The first 24 to 48 hours are critical to limit mold and secondary damage. Faster response often lowers total cost.
Can I dry it myself to save money?
You can start by shutting off the water, removing standing water, and running fans, but professional drying uses commercial dehumidifiers and moisture testing. DIY steps help, but professionals prevent hidden moisture and mold that cause higher costs later.
How do I know if the water is black or gray?
Clean water looks clear and comes from a supply line or rain. Gray water has some contamination from appliances. Black water involves sewage or floodwater and is hazardous. When in doubt treat it as black and call a pro.
