Quick answer

Water damage restoration averages $3,868, and most homeowners pay $1,383 to $6,369, according to HomeAdvisor's June 2026 cost guide. Per square foot, HomeAdvisor puts clean water (Category 1) at about $3.50, gray water (Category 2) at about $5.25 and sewage or floodwater (Category 3) at about $7.50. The biggest drivers are how dirty the water is, how much of the house got wet, and how long it sat before drying started. Rebuilding drywall, ceilings and floors is often billed on top of that.

Do this first: stop the damage and protect your claim

The longer water sits, the bigger the bill. These steps can shrink the job.

  1. Stop the water. Close the fixture valve or the main shutoff if a pipe or appliance is leaking.
  2. Check for electrical risk before you step in. If water is near outlets, cords or the panel, do not enter the water. Turn power off at the panel only if you can reach it from a dry spot; otherwise call the utility or an electrician.
  3. Take photos and video of the water, the damage and anything you throw out, before you move much. FEMA advises photographing discarded items for insurance claims. [1]
  4. Call your insurance company to open a claim and ask what they need before work starts.
  5. Move furniture, rugs and boxes out of the wet area and open windows if the weather allows.
  6. Start drying right away. EPA says to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth in most cases. [2]

Stop and call

If the water came from a sewer backup, a toilet with waste in it or outside floodwater, treat it as Category 3. Wear gloves, boots and eye protection, and keep children and pets away. If a ceiling is sagging, stay out from under it.

How much does water damage restoration cost in 2026?

HomeAdvisor's June 2026 cost guide puts the national average at $3,868, with most jobs between $1,383 and $6,369. Small jobs can run as little as $450 and large ones up to $16,000. [3] [4]

Angi's September 2026 guide shows the same average and range, so treat those two as one data set, not two. [4]

HomeGuide's February 2026 guide gives a separate estimate: $2,000 to $6,000 on average, with a full spread from $150 for a minor leak to $100,000 for a major flood with contaminated water. [5]

The two estimates overlap in the middle. A whole-house flood or sewage job is a different scale.

Cost per square foot by water category

Restoration companies sort water by how contaminated it is, using the IICRC S500 categories. The University of California, Riverside, which follows that standard, defines them this way. [6] The example sources come from HomeGuide's February 2026 guide. [5]

  • Category 1: water from a source that does not pose substantial harm to people, such as a broken supply line, faucet or rainwater leak.
  • Category 2: water with a significant degree of chemical, biological or physical contamination, such as an overflowing dishwasher or washing machine.
  • Category 3: grossly unsanitary water containing pathogens, from sewage or other contaminated sources, such as sewer backups or rising seawater.
Water damage restoration cost per square foot by category (HomeAdvisor, June 2026; HomeGuide, February 2026)
CategoryHomeAdvisor restoration, per sq ft (June 2026)HomeGuide extraction and drying, per sq ft (Feb. 2026)
Category 1 (clean water)About $3.50 ($3 to $4)$4 to $6
Category 2 (gray water)About $5.25 ($4 to $6.50)$6 to $9
Category 3 (black water)About $7.50 ($7 to $7.50)$9 to $12

HomeAdvisor's per-square-foot figures come from its June 2026 guide [3]. HomeGuide's February 2026 figures cover removing water and drying the area [5]. The two sources disagree by a few dollars per square foot, so use them as a range, not a price.

Category matters for more than the rate. HomeGuide says anything Category 3 water touches, including drywall, flooring, furniture and clothing, must be removed and replaced. [5] That is why sewage jobs climb fast.

Sources for the table: water category rates from HomeAdvisor [3]; class, material and after-hours notes from HomeGuide [5]; the 48-hour drywall rule from Massachusetts [7]; mold cost from HomeAdvisor's June 2026 mold guide [8]; repair costs from Angi [4].

Mold estimates vary by source. HomeAdvisor's June 2026 mold guide says about $10 to $25 per square foot [8], while HomeGuide's February 2026 guide says $15 to $30 per square foot [5].

What does a water damage restoration job usually include?

HomeGuide's February 2026 guide lists the usual steps a restoration contractor follows. [5] Use them to check that a quote covers the whole job.

  • Assessment: finding the water source and naming the category and class.
  • Water extraction: pumps and extractors for standing water, then wet vacuums for what is left.
  • Moisture readings: a moisture meter or infrared camera to find hidden wet spots in walls and floors.
  • Removal of wet materials: carpet, pad and trim that slow drying or cannot be saved.
  • Drying: air movers, fans and dehumidifiers until materials are dry.
  • Cleaning and sanitizing: HEPA vacuums or air scrubbers, plus an antimicrobial cleaning for Category 3 water.
  • Repairs: replacing flooring, drywall, trim and subfloor below the water line.

The rebuild is often a separate bill. HomeGuide notes that after the area is dried and sanitized, you may need other contractors, such as painters, plumbers, electricians or carpenters, to finish repairs. [5] Ask early whether your quote covers drying only or drying plus rebuild.

How insurance changes what you pay

Coverage depends on what caused the water. The Insurance Information Institute reports that water damage and freezing claims averaged $15,400 per claim in 2019 to 2023. [9]

  • Sudden vs. gradual: Washington's insurance commissioner says homeowner insurance usually covers sudden and accidental leaks, such as a burst pipe, but may not cover gradual leaks, such as a leaking faucet or foundation. [10]
  • Mold: homeowner insurance usually does not cover mold unless it comes from water damage the policy covers, though some insurers provide limited mold coverage. [10]
  • Your deductible: the deductible is subtracted from what your insurer pays. With a $500 deductible on a $10,000 covered loss, you would receive $9,500. [11]
  • Flood: most homeowners and renters policies do not cover flood damage. That needs a separate flood policy, such as one through the National Flood Insurance Program, which usually has a 30-day waiting period before it takes effect. [12]

Your own policy decides what is covered. Read the water damage and exclusions sections, find your deductible on the declarations page [11], and call your agent before you sign a work agreement.

How to read a quote and what to ask

HomeGuide recommends getting a written estimate that details the scope of work, materials, labor and other expenses, and comparing estimates from more than one company. [5] Angi suggests talking with the company about drying timelines, moisture monitoring and insurance documentation. [4]

  1. Ask for an itemized estimate, with extraction, equipment days, material removal, cleaning and disposal on separate lines.
  2. Ask whether they will record moisture readings each day and share the drying log with you and your insurer.
  3. Ask who handles the rebuild: the same company, a partner, or you.
  4. Ask whether they bill your insurance company directly and what you owe if the claim is denied.
  5. Ask whether after-hours or weekend visits add charges, before the crew starts.
  6. Ask for photos of anything they remove.

Safe to do yourself

A small Category 1 leak caught early, like a supply line drip under a sink, can often be handled with towels, a wet vacuum, fans and a dehumidifier. Keep indoor humidity below 60 percent, ideally 30 to 50 percent, while things dry. [2]

When waiting costs more

Time is the one cost driver you control. EPA says to clean and dry damp or wet building materials within 24 to 48 hours to prevent mold growth. [13] Massachusetts guidance says to cut out and discard wallboard that has not dried enough within 48 hours. [7] FEMA advises throwing out items that cannot be cleaned and dried completely within 24 to 48 hours. [1]

That shows up on the bill. Drying in place is one charge; cutting out drywall and removing mold are added charges. Mold removal alone averages $2,368 in HomeAdvisor's June 2026 mold guide. [8] Homeowner insurance usually does not cover mold unless it comes from covered water damage, so that part may be yours to pay. [10]

EPA says you can usually handle a moldy area smaller than about 10 square feet yourself. [2] If mold covers more than that, or drywall, carpet or subfloor is still wet after two days, the job has moved past DIY. For any health questions about mold exposure, talk to a doctor. EPA advises consulting a health professional before starting cleanup if you have health concerns. [2]

Common questions

What does water damage restoration consist of?

It usually includes an assessment of the water source and category, water extraction, moisture readings, removal of wet materials, drying with air movers and dehumidifiers, cleaning and sanitizing, and then repairs. HomeGuide's February 2026 guide lists these steps in that order. Repairs to drywall, floors and ceilings are often handled by other contractors. [5]

Is water damage repairable?

Usually, yes, if drying starts fast. EPA says to dry wet materials within 24 to 48 hours to prevent mold in most cases. [2] Massachusetts guidance says wallboard that has not dried within 48 hours should be cut out. [7] HomeGuide says anything Category 3 water touches must be removed and replaced. [5]

How much does it cost to unflood a basement?

Angi's September 2026 guide puts basement water damage at $500 to $1,500 for about an inch of clean water from a burst pipe, rising to $2,800 or more for two feet of sewage backup. [4] Rebuild costs for walls and floors are on top of that. If the water came from outside flooding, homeowners insurance usually will not cover it without a flood policy. [12]

Does insurance pay for water damage restoration?

Often, when the water came from a sudden and accidental event like a burst pipe. Gradual leaks and most mold usually are not covered, and flood needs a separate policy. [10] [12] Your deductible comes out of any payment, so check your own policy and call your agent before work starts. [11]

How long does water damage restoration take?

HomeGuide's February 2026 guide says smaller jobs with clean or gray water can be resolved in a few days, while major damage from a flood or black water can take several weeks or months. [5]
