Water Damage Restoration Cost Calculator
Most water damage restoration jobs land between $1,383 and $6,378, but the water's source and how long it sat matter more than the square footage: clean supply water runs about $3.50 per square foot, while sewage or flood water can hit $15. Answer four quick questions for a realistic range.
One thing to know up front: the clock is the biggest cost driver. Water dried within 24–48 hours is a cleanup; water left for days becomes a mold and tear-out job.
How this works
This estimate starts from 2026 per-square-foot restoration pricing organized by IICRC S500 water category — the industry standard restoration crews actually bill by. Category 1 (clean water from a burst pipe or supply line) runs about $3.50 per square foot; Category 2 (gray water from washing machine or dishwasher discharge) runs $4.00–$6.50; Category 3 (sewage or outdoor flooding) runs $7–$15 because contaminated porous materials are removed and replaced rather than dried. The national average job is $3,865, with most between $1,383 and $6,378 (HomeAdvisor/Angi).
How far the water spread is a proxy for the IICRC class of loss, and it scales the labor: floor-only losses are the base case, water wicking into walls or carpet adds baseboard removal, wall-cavity drying, and pad replacement, and ceiling or overhead saturation adds drywall tear-out and cavity drying on top of everything below it.
Time is the third input because the S500 standard says water degrades: clean water standing more than roughly 72 hours is treated as gray, and gray as black, since bacteria multiply in standing water. Past that window we also add a mold remediation line item ($1,100–$3,400 typical) — the EPA's guidance is that mold begins growing on wet porous materials within 24–48 hours. It's a screening estimate, not a quote: a local crew confirms scope with moisture meters on site.

Frequently Asked Questions
How much does water damage restoration cost per square foot?
It depends on the water category: about $3.50 per square foot for clean water (burst pipe, supply line), $4.00–$6.50 for gray water (appliance discharge), and $7–$15 for sewage or flood water, where contaminated materials must be removed rather than dried. Water in walls or ceilings adds tear-out labor on top.
Why does sewage or flood water cost so much more to clean up?
Category 3 water carries pathogens, so anything porous it touches — carpet, pad, drywall, insulation — is typically removed and replaced, not dried. Crews also work in protective gear and sanitize the structure. That turns a drying job into a demolition-and-rebuild job.
Does it really matter if I wait a few days?
Yes, more than any other factor. Mold starts growing on wet porous materials within 24–48 hours (EPA), and the IICRC standard treats water standing 72+ hours as more contaminated than its source. Waiting turns a few-thousand-dollar dry-out into a mold remediation ($1,100–$3,400 typical) plus material replacement.
Will homeowners insurance cover water damage restoration?
Usually yes for sudden, accidental events like a burst pipe or appliance failure — and restoration crews document moisture readings and damage specifically for claims. Gradual leaks and outdoor flooding are typically excluded (flooding needs separate flood insurance), so the source of the water matters as much for coverage as for cost.
