Water Damage Cost Estimator

Estimate restoration costs using IICRC S500 standard rates. Adjust for your affected area, water category, and primary material. Results are estimates — actual costs depend on contractor rates and site conditions.

About This Calculator

What rates does this calculator use?
Base rates come from IICRC S500 industry cost benchmarks: Category 1 at $3–$7/sq ft, Category 2 at $6–$14/sq ft, Category 3 at $12–$30/sq ft. These are national averages — regional rates vary.
Why does water category matter so much?
Category 3 (black water) requires full protective protocols, antimicrobial treatment, and removal of all porous materials in the contamination zone — dramatically increasing cost vs. clean water cleanup.
Is mold remediation included?
No — mold remediation is a separate cost. If your water damage is 48+ hours old, use the Mold Risk Assessment below to check whether mold remediation may be needed in addition to restoration.
How accurate is this estimate?
This provides a planning range. Actual costs depend on local contractor rates, extent of structural damage, drying time, and whether mold is present. Get 2–3 written estimates from IICRC-certified contractors before approving work.
