Per square foot, water damage restoration runs $3.75 to $7 for clean water, $7 to $12 for gray water, and $12 to $25+ for black water in 2026. Those rates cover mitigation — extraction, drying, antimicrobial. Rebuilding what was removed adds $20-$37 per square foot.

The two bills inside every restoration job

| Phase | Per sq ft (2026) | Included |
|---|---|---|
| Mitigation only | $3 – $7.50 | Extraction, drying, dehumidification, monitoring |
| Repairs added | +$20 – $37 | Drywall, insulation, flooring, trim, paint |
| Category 3 full scope | $32 – $62 total | Demo + disposal + PPE + rebuild |
Do the math for your space
A 200 sq ft bedroom with a Category 1 supply-line leak: 200 × $3.75-$7 = $750-$1,400 to dry, plus repairs only if drywall stayed wet. A 600 sq ft finished basement with Category 2 water: 600 × $7-$12 = $4,200-$7,200 mitigation — and if flooring and lower drywall go, repairs can double it. That math is why the national average sits at $3,867.
Why the category multiplies the rate
Category 1 can often dry in place. Category 2 requires removing what absorbed contaminated water. Category 3 mandates full demolition of porous materials, PPE and disposal — non-negotiable for health. The clock matters too: clean water left standing becomes Category 2 in about 48 hours. Full explainer: categories 1, 2 and 3.
Quote checklist (bring this)
Ask every bidder: Which category are you classifying, and why? What are today’s moisture readings and what target ends drying? Which materials will you remove — and which can dry in place? Is reconstruction quoted separately? Equipment days included or billed daily? Those five questions kill most padding.

FAQ
Why is my “clean water” quote $9 per square foot?
Either slow-drying materials (hardwood, plaster), poor access, or the contractor is classifying it Category 2. Make them justify the category in writing.
Are equipment days extra?
Often. Air movers ($20-$40/day each) and dehumidifiers ($50-$100/day) multiply fast — confirm whether the rate includes a set number of days.
Does insurance price per square foot too?
Adjusters use the same industry software (Xactimate). If their square footage disagrees with your contractor’s, reconcile that number first. See what insurance pays.
