Sewage in Basement Cleanup Cost Calculator
Enter the size of the wet area and what got wet to see a typical national price range for sewage backup cleanup and drying. It is an estimate only; the real price comes from the walkthrough.
Estimate the Cost
Typical range: $750 to $1,400
How it works: typical national figures of about $3.75 to $7 per square foot for clean water, $4.50 to $8.50 for gray water and $7 to $13 for black water, multiplied by 1.25 to 1.7 for drywall, ceilings, hardwood or finished basements and by 1.25 when the water sat for more than two days, with a small-job minimum. Pipe repair and rebuild are not included. Estimate only, not a quote.

Typical Cost to Clean Sewage From a Basement
Typical national cleanup ranges start near $1,500 for a small hard-surface loss and can exceed $20,000 when a finished basement has widespread contamination. The amount of wet material and work required determines the actual cost. A low water mark does not always mean a small job because wastewater can enter carpet pad, insulation and flooring joints. The crew assesses the actual contaminated footprint before defining the work.
- Small hard-surface area: $1,500 to $3,500. Typical extraction and cleaning with little removal
- One finished room: $3,500 to $7,000. Typical flooring or wallboard removal plus drying
- Several finished rooms: $7,000 to $12,000. Typical broader contamination and more equipment
- Widespread basement loss: $12,000 to $20,000+. Typical extensive removal and longer drying
What changes the price
- How far sewage traveled beneath floors and behind walls
- Whether carpet, insulation and wallboard must come out
- The amount of sludge and surface cleaning
- How long retained materials take to dry
