How Much Does Water Damage Restoration Cost?
Water damage repair splits into two phases — mitigation (extraction and drying) and restoration (rebuilding) — and the water category drives the price. A clean Category 1 leak often runs $1,200 to $5,000 all-in, a grey-water flooded basement $3,500 to $15,000, and a black-water sewage backup $5,000 to $20,000+. Full restoration that rebuilds walls and floors typically costs about twice the mitigation.
Mitigation is priced roughly $4 to $12 per square foot depending on the water category, plus drying equipment per room; a full rebuild adds about $20 per square foot. Speed matters — mold can start in 24 to 48 hours, so acting fast keeps the cost down. Use the calculator above to price your loss, then read on for what drives each line — including whether insurance will cover it.

The 6 Factors That Drive Your Quote
1. Affected Area & Rooms
Mitigation is priced largely per square foot of wet area, so the footprint is the foundation of the estimate. The number of affected rooms matters too because each room needs its own drying equipment — figure roughly $300 per room for several days of air movers and dehumidifiers. A small leak in one room prices very differently from a flood across several.
2. Water Category
How contaminated the water is drives the rate: clean Category 1 (~$4/sq ft) lets you save materials, grey Category 2 (~$7/sq ft) means removing porous materials, and black Category 3 (~$12/sq ft) — sewage or flood water — requires full tear-out, disposal, and disinfection. The jump from clean to black water can triple the per-foot cost before any rebuild.
3. Scope: Mitigation vs. Rebuild
Extraction and drying (mitigation) is the emergency phase and the baseline cost. If you also need reconstruction — new drywall, insulation, flooring, trim, and paint — that adds about $20 per square foot, roughly doubling a mitigation-only job. The calculator lets you price drying alone or a full dry-and-rebuild so you can see both halves of the project.
4. Drying Equipment & Time
Industrial air movers and dehumidifiers run continuously for about 3 to 5 days, with daily moisture checks. More wet area and more rooms mean more equipment and rental days. Water bound in hardwood or concrete dries slowest and can need specialized gear, extending the timeline and cost — drying time is one of the biggest variables in the final bill.
5. Mold Risk
Mold can start growing in 24 to 48 hours, so fast drying is the cheapest mold prevention there is. If the water sat, or the category is grey or black, antimicrobial treatment or full remediation is often needed (about $2/sq ft here). Visible mold triggers containment and specialized removal protocols that add meaningfully to the cost — acting fast is what keeps this line small.
6. Contents & Debris
Beyond the structure, a job may include water-extracting carpet, hauling wet debris to a dumpster, and packing out and storing your furniture and belongings while the space dries and rebuilds. These are common line items on larger losses. The calculator breaks them out so the estimate reflects your actual scope rather than the drying alone.
Insurance, Speed, and What to Do First
Water damage is one of the few home problems where the first few hours change the whole cost. Move fast, document for insurance, and know which losses a policy actually covers.
In the first hours
- Stop the source (shut off the water) and kill power to affected areas if it's safe.
- Photograph everything before you clean up — insurers want proof of the loss and its extent.
- Get extraction and drying started immediately — mold can begin in 24 to 48 hours.
- Don't touch Category 3 (sewage) water yourself — it's a biohazard for pros in protective gear.
Is it likely covered?
- Usually covered: sudden, accidental events — a burst pipe, an overflowing appliance, a failed water heater.
- Usually not: gradual leaks and long-term seepage, treated as deferred maintenance.
- Needs a separate policy: flood water rising from outside (NFIP or private flood insurance).
- Often needs a rider: sewer or drain backups — check before you assume you're covered.
How to Vet and Hire a Restoration Company
In an emergency it's tempting to hire the first truck that shows up, but a few quick checks protect you from overbilling and shoddy drying. Before you sign:
- Confirm IICRC certification (the industry water-restoration standard) plus state licensing and insurance.
- Ask if they bill insurance directly and use standard Xactimate pricing — most reputable firms do.
- Get the scope in writing: what's being extracted, torn out, treated, and dried, and for how long.
- Be wary of pressure to sign a broad "work authorization" or an assignment of insurance benefits before you understand it.
What a complete quote should spell out
- The water category, affected area, and rooms being dried.
- Whether it's mitigation only or turn-key (drying plus reconstruction).
- Daily moisture monitoring and how drying completion is verified.
- Mold treatment, debris disposal, content pack-out, and how the deductible is handled.
Methodology & Sources
This calculator prices mitigation from a per-square-foot rate set by the water category (Cat 1 clean, Cat 2 grey, or Cat 3 black), adds a per-room drying-equipment allowance, and — if you choose a full rebuild— adds a reconstruction rate on top, plus flat and per-foot add-ons for mold treatment, carpet extraction, debris, and content pack-out. A minimum emergency call-out applies, and the result is adjusted to your ZIP code's regional price level. In short: (Affected Sq Ft × Category Rate) + Equipment + Rebuild + Add-ons, then localized. Ranges are aligned with IICRC S500 practice and calibrated against our aggregated restoration quotes.

Most water damage jobs land between $1,200 and $20,000+, and the water category drives the range. A small clean-water leak (Category 1) is often $1,200 to $5,000 all-in, a flooded basement of grey water (Category 2) $3,500 to $15,000, and a sewage backup (Category 3, black water) $5,000 to $20,000+. Mitigation alone — extraction, drying, and removing wet materials — is the lower figure; full restoration that also rebuilds drywall, flooring, and paint typically runs about twice the mitigation cost. Affected square footage, how many rooms need drying equipment, and add-ons like mold treatment round out the price.
Usually, if the water is 'sudden and accidental' — a burst pipe, an overflowing appliance, or a failed water heater are commonly covered by a standard homeowners policy. What's typically not covered: gradual leaks and long-term seepage (seen as a maintenance issue), and flood water rising from outside, which requires separate flood insurance through the NFIP or a private flood policy. Sewer backups often need a specific rider too. File promptly, document everything with photos before cleanup, and mitigate fast to prevent further damage — insurers can deny claims where delay let the damage spread.
The category describes how contaminated the water is, and it dictates what can be saved. Category 1 is clean water from a supply line, rain, or a fresh-water appliance — dried quickly, many materials can be saved. Category 2 (grey water) carries some contamination — from a dishwasher, washing machine, or sump-pump overflow — and porous materials often have to go. Category 3 (black water) is grossly contaminated — sewage backups and rising flood water carrying bacteria — and almost everything porous it touches (carpet, pad, drywall, insulation) must be removed and disposed of, with the area disinfected. Cost climbs sharply from Category 1 to 3 because of the tear-out and disposal.
Immediately — water damage is a race against mold. Mold can begin growing in 24 to 48 hours on wet, porous materials, and once it takes hold, remediation adds significant cost and health risk. Fast extraction and professional drying (industrial air movers and dehumidifiers) pull moisture out of materials before mold gets established, which is why restoration companies advertise 24/7 emergency response. Beyond mold, standing water keeps wicking up drywall and into subfloors and framing, expanding the damage every hour. The single best thing you can do is stop the source, get the water out, and start drying as quickly as possible.
That's a 'flood cut.' Drywall wicks water upward like a sponge, so even if only the floor flooded, moisture climbs into the wall. Cutting out the bottom 2 to 4 feet of drywall lets air reach behind the wall to dry the studs, bottom plate, and insulation and prevents mold from growing inside the cavity. Wet insulation is usually removed too, since it holds water and loses its R-value. It looks drastic, but it's far cheaper and safer than sealing moisture inside the wall and dealing with mold and rot later. The removed section is then rebuilt during the restoration phase.
It depends on the water category. With Category 1 clean water, carpet can often be saved if it's extracted and dried fast, though the pad underneath is usually replaced. With Category 2 or 3 water, carpet, pad, and other porous materials that got wet generally must be removed and disposed of because they can't be reliably disinfected. Non-porous items (tile, sealed concrete, glass, metal) can usually be cleaned and kept. A restoration tech uses moisture meters to decide what's salvageable versus what has to go — saving materials where it's safe keeps the bill down.
Mitigation is the emergency phase: stopping the water, extracting it, removing unsalvageable wet materials, applying antimicrobial treatment, and drying the structure with equipment over several days. Restoration (reconstruction) is putting it back together — new drywall, insulation, flooring, trim, and paint. Some companies are 'turn-key' and do both; others do only the drying and hand you off to a general contractor for repairs. Reconstruction typically costs roughly twice the mitigation, which is why the calculator separates 'extraction & drying only' from 'dry & repair/rebuild' — the rebuild adds about $20 per square foot on top of the mitigation.
Drying a typical area takes about 3 to 5 days with professional dehumidifiers and air movers running continuously, with daily moisture checks until readings hit target. Category 3 jobs add time for tear-out and disinfection, and water bound in hardwood or concrete (a 'Class 4' loss) dries slowest and may need specialized equipment. Reconstruction is a separate phase afterward and depends on scope — a small drywall-and-paint repair might be a few days, while replacing flooring across several rooms can take a couple of weeks. Restoration is often billed on time-and-materials with industry (Xactimate) pricing, so the final bill tracks actual moisture readings and drying time.
