1. What kind of water, and where

Water category

Broken supply line, faucet, or rainwater leak. Lowest health risk. Restoration companies call this Category 1.

Total square footage touched by water, across all affected rooms.

How long did the water sit before cleanup started?

2. What got wet

Priced across the affected floor area above.

Wall length times how high the water wicked, plus any wet ceiling. Left blank, the tool assumes a square room wet 2 feet up the walls: 113 sq ft.

3. Insurance

Filing a homeowners insurance claim?

  • Water extraction and drying, clean water (200 sq ft)$600 - $1,200
  • Carpet and pad: clean or replace (200 sq ft)$200 - $2,200
  • Drywall: repair or replace (113 sq ft of wall)$170 - $396

Mold risk: low so far

HomeGuide reports smaller, localized clean or gray water damage is usually resolved in a matter of a few days once a restoration crew starts extraction and drying.

Running your own dehumidifier while you wait for a crew: at the US average home electricity rate of 18.31 cents per kWh (EIA, July 2026), running one around the clock costs about 44 cents a day for every 100 watts it draws. The watts are printed on its label. A 50-pint ENERGY STAR unit working at full capacity uses no more than about 11.8 kWh a day under the program's efficiency minimum, or about $2.16 a day, so two or three days of drying costs a few dollars.

Homeowners insurance typically covers water damage that is sudden and accidental, such as a burst pipe or an appliance that suddenly failed, minus your deductible. It typically does NOT cover damage from neglect (a slow leak you knew about) or from flooding (water entering from outside, like a storm or rising water), which usually needs a separate flood insurance policy. If you are not sure yet whether this is covered, photograph the damage and its cause now, before cleanup starts, so you keep the option open either way.

5. National reference by damage class

Restoration companies also grade jobs by class (severity), separate from the category (water source) used above. This table is a national ballpark, not driven by what you entered.

ClassTypical totalWhat it looks like
Class 1$150 - $500Small, localized leak with minimal absorption into materials (e.g. an overflowing toilet)
Class 2$500 - $5,000Up to 12 inches of standing water affecting an entire room, or a burst pipe reaching walls and flooring
Class 3$1,000 - $15,000Water has soaked ceiling, walls and flooring in one or more rooms (e.g. a leaking roof or ice dam)
Class 4$15,000 - $100,000Disaster-level, prolonged flooding with major structural damage

Enter the type of water, the affected area and what got wet to see the typical cost of extraction, drying and repairs, how much time you have before mold becomes a risk, and whether a quote you already have is fair.

How this is calculated

The estimate starts with a per-square-foot rate for water extraction and drying, based on the contamination category you select: clean, gray or black water. The wet flooring (carpet and pad, or hardwood) adds a repair line priced across the affected floor area. Wet drywall or plaster adds a line priced by wall and ceiling area, which you can enter or leave for the tool to estimate. Carpet hit by clean water is priced as clean or replace; carpet hit by gray or black water is priced as replacement, since the published cleaning prices cover clean water only and HomeGuide says anything black water touches must be removed and replaced. If you flag visible mold, or the water sat past the 48-hour mark of the EPA's drying window, a mold remediation line is added. Black water alone does not add one. No total drops below the $150 to $500 that the cited guides give for the smallest jobs, and a total past $100,000, the top of every cited range, is flagged for an on-site estimate instead. None of these rates are invented; each comes from a published national cost guide, and where guides disagreed the wider band is shown, so the tool is never more precise than the data behind it.

Worked example

A washing machine drain hose came loose during an overnight cycle and flooded a 15-by-20-foot (300 sq ft) finished basement with gray water. The homeowner found it the next morning, about 20 hours after it started, and the carpet, pad and the bottom two feet of drywall along all 70 feet of wall (140 sq ft) are soaked. No mold is visible yet, and they plan to file an insurance claim.

Line itemTypical range
Water extraction and drying, gray water (300 sq ft)$1,200 - $2,700
Carpet and pad: replace (300 sq ft)$600 - $3,150
Drywall: repair or replace (140 sq ft of wall)$210 - $490
Total$2,010 - $6,340

Because the water sat under 24 hours and no mold is visible, the calculator adds no mold remediation line, and its mold risk badge reads "low so far." If this same homeowner had not found the leak for three days instead of one, the tool would add a $1,425-$9,000 mold remediation line automatically, since 300 sq ft would have sat well past the EPA's 24-48 hour drying window. The total would move from $2,010-$6,340 to $3,435-$15,340, which is what those two extra days can cost.

The mold clock: why timing changes the price more than square footage

Most water damage cost guides quote a range by category and area, but the single biggest lever homeowners actually control is how fast cleanup starts. The EPA advises drying water-damaged areas within 24 to 48 hours to prevent mold growth, and says that in most cases mold will not grow on materials dried in that window. Past that window the risk of mold rises, so budget for an inspection. Mold remediation comes on top of everything else, and published prices run from $4.75 per square foot (Fixr, mold cleanup within a water job) to $30 per square foot (HomeGuide, full remediation). On a 300-square-foot area that is $1,425 to $9,000, and the high end is more than the entire extraction-and-repair cost for the same space caught early. If you cannot get a restoration crew out immediately, running box fans, a dehumidifier and pulling up soaked carpet yourself (where safe, and only for clean or gray water) buys time against that clock while you line up a contractor.

Category vs. class: reading a restoration quote

A restoration quote should tell you both the water category (how contaminated it is, which drives the extraction rate and whether materials must be replaced rather than dried) and the damage class (how much of the structure it reached, which drives total scope). A quote that only gives a lump sum without naming either one is harder to sanity-check against published ranges. Ask for the category and class in writing, along with an itemized breakdown of extraction and drying versus repairs, so you can compare it against the line items above instead of just a single number.

Before you sign: what to ask the restoration company for

If the quote checker above puts your quote above the typical range, these five items usually show where the difference comes from.

Why other calculators show a different number

Some online estimators quote a much higher rate per square foot. Homewyse lists water damage repair at $20.85 to $38.25 per square foot (September 2026, checked September 28, 2026). That rate covers removing, repairing and patching the damaged finished surfaces, measured across the whole finished surface area, and water extraction and drying are not among the work it lists. This tool splits the job differently: extraction and drying priced by floor area, then only the materials you say got wet, each at its own published rate. The two numbers describe different scopes of work, so compare quotes line by line rather than by one per-square-foot figure.

What insurance usually does, and does not, cover

Homeowners insurance is built around the word "sudden." A pipe that bursts without warning is typically covered, minus your deductible. A slow leak under a sink that you knew about for months, or floodwater that entered from outside, typically is not, and flood damage usually needs a separate flood insurance policy. Bob Vila notes that most insurance companies don't accept a homeowner's own category diagnosis when processing a claim; a licensed professional has to categorize and classify the damage. Photograph the damage and its likely cause before any cleanup starts, keep every receipt, and ask a restoration company whether they handle insurance claim documentation directly, since many do and it can speed up approval.

Questions people ask

How much does water damage restoration cost?

Bob Vila reports homeowners typically pay between $1,305 and $5,707, with a national average around $3,455. HomeGuide puts the average at $2,000 to $6,000, with a full range from $150 for a small, localized clean-water leak up to $100,000 for a major flood. The biggest swing factor is the water's contamination category: extraction and drying alone runs about $3 to $6 per square foot for clean water, $4 to $9 for gray water, and $7 to $12 for black water, before any repairs.

What is the difference between a water damage "category" and a "class"?

Category describes the water source and how contaminated it is: Category 1 is clean (a supply line or faucet), Category 2 is gray water (an appliance like a dishwasher or washing machine), and Category 3 is black water (sewage, flooding, or groundwater), each requiring more protective cleanup and, for Category 3, replacement of anything it touched. Class describes severity, based on how much water and how large an area is affected, from Class 1 (a small, localized leak) to Class 4 (a disaster with major structural damage). A category-3, class-1 job (a small sewage backup) and a category-1, class-4 job (a whole finished basement flooded with clean water) can land in very different price ranges even though only one factor changed.

How fast do I need to dry things out before mold becomes a problem?

The EPA says it is important to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth; in most cases, materials dried within that window will not grow mold. Past that window the risk of mold rises, so budget for a mold inspection ($300 to $650, HomeGuide) and possibly mold remediation. Published remediation prices vary widely: Fixr lists mold cleanup within a water damage job at $4.75 to $5.50 per square foot, Bob Vila puts a typical job at $1,500 to $4,000, and HomeGuide puts full remediation at $15 to $30 per square foot, or $1,500 to $15,000-plus total.

Does homeowners insurance cover water damage restoration?

Usually, if the damage was sudden and accidental, like a pipe that suddenly burst or an appliance that suddenly failed, minus your deductible. It typically does not cover damage from a leak you knew about and ignored, or from flooding (water entering from outside), which usually needs a separate flood insurance policy. Bob Vila notes that only a licensed professional can categorize and classify water damage, and that most insurance companies don't accept category diagnoses from homeowners when processing claims. Photograph everything before cleanup starts either way.

Why was my first insurance check less than the restoration estimate?

Often because of depreciation. The Insurance Information Institute explains that an actual cash value payment is the replacement cost minus depreciation, the drop in value from age and wear. The North Carolina Department of Insurance notes that with replacement cost coverage, the insurer may pay the actual cash value first, then pay the difference, called recoverable depreciation, once the repairs are done and receipts are submitted. Policies without replacement cost coverage pay actual cash value only. Ask your adjuster in writing whether your policy has recoverable depreciation and how long you have to finish repairs and claim it.

How long does water damage restoration take?

HomeGuide reports that smaller, localized clean- or gray-water incidents are usually resolved in a matter of a few days once a crew starts extraction and drying. Major damage involving black water or a natural disaster can take several weeks or months, depending on the extent of structural repairs and how many contractors are available.

Is it worth doing water damage cleanup myself?

For a very small, Class 1 clean-water spill you catch immediately, DIY extraction and fans can work. Once water has sat past 24 to 48 hours, covers more than a small area, or came from anything other than a clean supply line, professional extraction and industrial dehumidification matter: they dry materials fast enough to head off mold and check for moisture trapped behind walls or under flooring that a wet vac and box fan will not reach.
