Water Damage Restoration Cost
Water damage restoration costs $2,000–$6,000 on average — from $150 for one wet corner to $100,000 for whole-home flooding. Price your damage by how far the water spread and how dirty it was.
Restoration crews price two things: how far the water spread — one damp corner and a soaked-through floor are different classes of job — and how dirty the water was, because clean supply-line water gets dried while sewage-touched materials get removed. Answer both and you have the estimate; act fast and you keep it from climbing.
How far did the water get?
One damp area of one room is Class 1. Standing water — up to a foot deep — in a room is Class 2. Water that soaked into walls, ceilings, and subfloors across one or more rooms is Class 3. Whole-home flooding from a storm or days-long leak is Class 4.
What kind of water was it?
Clean water comes from supply lines, faucets, or rain. Gray water is used water — dishwasher or washer overflow — with mild contamination. Black water is sewage, toilet backflow, or ground flooding: hazardous, and everything it touched gets removed rather than cleaned.
Cost to restore Class 2 damage from clean water
$1,500–$3,250
professional extraction, drying, sanitizing, and the repairs that follow
The clock is the cost multiplier
Water damage compounds by the hour — drywall wicks, subfloors swell, and mold establishes within 24–72 hours, adding a remediation bill on top of the water one. After-hours emergency response costs extra, but waiting usually costs more. First moves: stop the source, move what's dry, photograph everything, and get extraction started — even a wet-vac and fans tonight beat a crew on Thursday.
What insurance will and won't do
Home insurance covers water damage that's sudden or accidental — the burst pipe, the failed water heater. It does not cover neglect (the drip you ignored all year), and flood water needs a separate flood policy, full stop. Two practical rules: document before touching anything, and note that many policies require professional remediation for the claim to pay — DIY-ing a big loss can cost you the coverage.
Based on the published class price sheet ($150 minor to $100,000 disaster) with water type positioning the estimate inside its class range. Extraction and drying alone runs $4–$12 per square foot by contamination level. Follow-on trades — drywall, flooring, painting, electrical — bill separately on bigger losses. Prevention context: a sump pump runs $600–$2,500 and basement waterproofing $6,000–$18,000.
💡About this calculator▼
Water damage is the most time-sensitive bill in homeownership — the price is still being written while you read the estimate, because drywall keeps wicking, subfloors keep swelling, and mold starts its clock at 24 hours. The good news: restoration pricing follows two questions you can answer standing in the wet room. How far did the water get, and how dirty was it?
The spread question is what the industry calls class: one damp area of one room runs $150–$500 (often homeowner-fixable), standing water in a room runs $1,500–$5,000, water that soaked through walls, ceilings, and subfloors across rooms runs $5,000–$15,000, and whole-home flooding — the hurricane tier — runs $15,000–$100,000.
The dirtiness question is category, and it decides what survives. Clean water from a supply line or rain gets extracted and dried at $4–$6 per square foot, and most materials are saved. Gray water from an appliance overflow runs $6–$9 with mild contamination. Black water — sewage, toilet backflow, ground flooding — runs $9–$12 per square foot and changes the rules entirely: everything it touched gets removed and replaced, not cleaned.
Answer both below for your estimate. Then act on the one lever you still control: speed. Tonight's wet-vac and fans are worth real money against Thursday's mold remediation bill.
Two questions, straight from how restoration crews actually estimate.
Class — how far the water spread. The published price sheet runs: Class 1 at $150–$500 for small leaks confined to one area of a room, damage the source itself calls homeowner-repairable; Class 2 at $1,500–$5,000 for up to a foot of standing water in at least one room; Class 3 at $5,000–$15,000 when water permeated every part of one or more rooms — ceiling, walls, flooring, subflooring; and Class 4 at $15,000–$100,000 for prolonged whole-home flooding from high water or hurricanes.
Category — how contaminated the water was. Clean water (Category 1: broken supply lines, faucets, rainwater) extracts and dries at $4–$6 per square foot with no health risk, and carpets, trim, and drywall can usually be cleaned and repaired. Gray water (Category 2: dishwasher and washing-machine overflow) runs $6–$9 with mild contamination. Black water (Category 3: toilets, sewer backups, rising groundwater) runs $9–$12 — and everything below its flood line gets removed and disposed of as hazardous waste rather than restored.
How they combine. The class sets your published range; the water type positions you inside it — clean-water losses land in the lower half, gray in the middle, black at the top, exactly the pattern the published data describes. The calculator shows both the positioned estimate and the full class range, so nothing hides.
📐How it's calculated▼
Estimate = your class's published range, positioned by water type.
Class ranges: Class 1 (one wet area) $150–$500 · Class 2 (standing water in a room) $1,500–$5,000 · Class 3 (soaked rooms, walls & subfloor) $5,000–$15,000 · Class 4 (whole-home flooding) $15,000–$100,000.
Water type positions the estimate: clean water → the lower half of the class range · gray water → the middle · black water → the upper half — following the published rule that costs run lowest for clean-water leaks and highest for contaminated black water.
Extraction and drying rates underneath it all: clean $4–$6 per sq ft · gray $6–$9 · black $9–$12. These are inside the class ranges, not added on top.
Worked example: a laundry-room washer overflow with standing water is Class 2 gray — roughly $2,400–$4,100 of the published $1,500–$5,000. The same room flooded by a sewer backup prices as Class 2 black at $3,250–$5,000, with everything the water touched being replaced rather than cleaned.
🔍Finding your inputs▼
How far did the water get? Walk it honestly. A single damp patch, one soaked corner, a puddle under the sink: Class 1. Water you had to step through in one room: Class 2. Squishy floors, stained ceilings below, damp walls above the baseboard, or multiple rooms involved: Class 3 — soaked structure, not just wet surfaces. Flooding through the home from storm, hurricane, or a supply line that ran for days: Class 4.
What kind of water was it? Trace the source. Supply lines, faucets, water heaters, and rain are clean. Anything that already ran through an appliance — dishwasher, washer — is gray. Anything involving a toilet, a sewer line, or water rising from the ground is black, no exceptions, even if it looks clear. When the source is unknown or mixed (storm water usually is), treat it as black — that's how the crews will treat it, and their pricing follows.
⚠️Special situations▼
The water is still coming — what do I do this minute?
Source first: the main shutoff for anything plumbing (know where it is before you need it), or stay clear entirely if the water is electrical-adjacent or black. Then triage in order — power off to affected circuits if safe, valuables and furniture up and out, photos and video of everything for insurance, then extraction starts: wet-vac, mops, fans, open windows. Every hour of standing water converts more of the house from 'dry it' to 'replace it.'
It happened while we were away — the water ran for days
Prolonged exposure escalates everything: what would have been a Class 2 mopping becomes Class 3–4 saturation, and mold has had its 24–72 hours many times over — so budget for mold remediation on top of water restoration, and expect the crew to open walls to check inside cavities. Insurance nuance: sudden-and-accidental origin (a burst line) is generally still covered even if discovered late, but document the timeline honestly; our mold remediation page prices that half of the bill.
Insurance says flood damage isn't covered — but it came from rain?
The dividing line is the water's path: rain through a damaged roof or window is storm damage (typically covered); water rising from the ground — overflowing rivers, storm surge, saturated soil coming through the foundation — is flood, and flood requires a separate flood policy, full stop. It's the most litigated line in property insurance. If you're in any flood-prone area without flood coverage, that policy costs far less than one Class 4 uninsured basement.
The restoration quote seems huge for what looks like minor damage
Ask for the moisture map. Water hides — a small visible stain can sit on a saturated wall cavity or subfloor, and crews price what their meters find, not what eyes see. A legitimate firm shows you readings; a padding one shows you adjectives. Get a second bid on anything over a few thousand dollars, and make both firms separate mitigation from reconstruction so you're comparing the same scopes.
Can I dry it out myself and skip the pros?
For true Class 1 clean-water damage — one contained area, caught fast — yes: extract, run fans and a dehumidifier for days (not hours), and verify dryness before closing it up. Three stop signs: gray or black water (contamination isn't a DIY problem), water that got into walls or under flooring (you can't dry what you can't reach), and anything you'll claim on insurance — many policies require professional remediation for the claim to pay, which makes the DIY savings an expensive false economy.
❓Common questions▼
How much does water damage restoration cost?
Water damage restoration costs $2,000–$6,000 on average, with the full range running $150 to $100,000 by severity: one wet area of a room runs $150–$500, standing water in a room $1,500–$5,000, water soaked through walls and subfloors $5,000–$15,000, and whole-home flooding $15,000–$100,000. Contamination moves you within those ranges — clean supply-line water costs least, sewage and floodwater the most.
What do restoration companies charge per square foot?
Extraction and drying runs $4–$12 per square foot by water type: $4–$6 for clean water from supply lines or rain, $6–$9 for gray water from appliance overflows, and $9–$12 for black water from sewage or ground flooding. The premium isn't just labor — black water requires protective equipment, hazardous-waste disposal, and replacing rather than cleaning everything it touched.
What is the difference between clean, gray, and black water?
It's the contamination ladder. Clean (Category 1) comes from sanitary sources — broken supply lines, faucets, rainwater — and poses no health risk. Gray (Category 2) has been used: dishwasher and washer overflow, with mild contamination. Black (Category 3) is hazardous: toilets, sewer backups, and any water rising from the ground. The practical difference is salvage — clean and gray-damaged materials can often be dried and repaired; anything black water touched must be removed and replaced.
Does homeowners insurance cover water damage?
When it's sudden or accidental — a burst pipe, a failed water heater — yes. Not when it results from neglect (the slow leak you ignored), and never for flood water without a separate flood policy: water rising from the ground is flood, no matter the storm that caused it. Two claim-protecting habits: document everything before cleanup starts, and use professional remediation — many policies require it for the claim to pay.
How fast does water damage get worse?
By the hour. Within minutes, water wicks into drywall and swells wood; within a day, mold begins establishing (its window is 24–72 hours); within days, subfloors delaminate, framing saturates, and a drying job becomes a demolition job. That's why after-hours emergency extraction — despite its premium — usually saves money: the restoration industry's whole pricing ladder is really a measure of how long water sat.
How long does water damage restoration take?
Mitigation is fast, drying is not: extraction happens in hours, but structural drying runs 3–5 days of industrial dehumidifiers and air movers, verified by moisture readings — closing walls over damp framing is how mold callbacks happen. Reconstruction (drywall, flooring, paint) follows on its own schedule, from days for a room to months after whole-home flooding. Insist on documented dry-verification before any rebuild starts.
