Water Damage Restoration

Emergency water extraction, structural drying, and flood damage restoration for homes and businesses.

Find verified water damage restoration professionals in your area.

Water damage restoration is the extraction, drying and repair of a building after water intrusion, performed to the IICRC S500 standard. The category of the water, clean, grey or contaminated, decides how much can be dried and saved and how much has to be removed.

  • Typical cost: $1,300 to $5,600
  • Mold can begin growing 24 to 48 hours after intrusion
  • Sudden and accidental water is generally covered; gradual leaks generally are not
  • Flooding from outside needs separate flood insurance, usually NFIP

What to Expect

1

Assessment and categorisation

Technicians identify the source, classify the water as Category 1 clean, Category 2 grey or Category 3 contaminated, and map how far it spread with moisture meters and thermal imaging. That classification drives every decision that follows.

2

Water extraction

Standing water is pumped and vacuumed out. Speed matters more here than anywhere else in the process, because material that is wet for longer moves from salvageable to removable.

3

Removal of unsalvageable materials

Saturated carpet padding, swollen baseboard, wet insulation and drywall that has wicked water are cut out. With Category 1 water caught early, much of this can instead be dried in place.

4

Structural drying

Air movers and commercial dehumidifiers dry the structure over several days. Technicians take daily moisture readings rather than judging by touch, because framing and subfloor hold water long after surfaces feel dry.

5

Verification and reconstruction

Drying continues until documented moisture targets are met, then repairs begin. Ask for the daily logs. They are your evidence the building was actually dry before it was closed up.

Typical Cost

Low end$500
Typical range$1,300 to $5,600
High end$25,000+

Companies typically charge $75 to $175/hour for biohazard remediation labor.

Cost by scenario

  • Small clean-water leak, one room, caught early$500 to $1,500
  • Single room with carpet and drywall removal$1,500 to $4,000
  • Multiple rooms or a finished basement$4,000 to $12,000
  • Whole home, contaminated water or structural repair$12,000 to $25,000+

What affects the cost

  • Water category: clean, grey or contaminated
  • How many hours passed before extraction started
  • Square footage affected and how much is porous material
  • Days of equipment rental needed to hit the drying target

Insurance Coverage

Most water damage claims turn on one distinction: water that arrived suddenly and by accident is generally covered, and water that seeped in over time generally is not.

  • A burst pipe, a failed water heater, an overflowing appliance or a storm-damaged roof is normally a covered cause of loss, and the resulting damage is covered with it.
  • A slow leak under a sink, a dripping supply line or long-term seepage is normally excluded as a maintenance issue, even when the eventual damage is severe.
  • Flooding from outside the building, including storm surge and rising groundwater, is never covered by a standard homeowners policy. That requires separate flood insurance, usually through the NFIP, with a waiting period before it takes effect.
  • Photograph everything before cleanup begins and keep the moisture logs. Adjusters routinely ask restoration companies for drying documentation, and its absence weakens the claim.

Frequently Asked Questions

How soon do I need to start drying?

Within hours. Mold can begin growing in 24 to 48 hours, and materials that could have been dried in place become removal jobs once they stay saturated. The single largest driver of the final bill is how long the water sat.

What is the difference between Category 1, 2 and 3 water?

Category 1 is clean water from a supply line or a tap. Category 2, sometimes called grey water, comes from appliances like a washing machine or dishwasher and carries some contamination. Category 3 is grossly contaminated, including sewage and flood water. Note that clean water degrades to a higher category the longer it sits.

Can I just use fans and a household dehumidifier?

For a very small spill on hard flooring, often yes. For anything that reached carpet, walls or subfloor, household equipment does not move enough air or pull enough moisture to dry a structure before mold starts. The risk is not the visible water, it is the water inside the wall cavity.

How long does the drying take?

Typically three to five days with commercial equipment running continuously, sometimes longer for dense materials like hardwood or plaster. Reconstruction happens after drying and is a separate timeline.

Do I have to move out?

Often not. Drying equipment is loud and warm but the building usually stays habitable. Category 3 water, extensive removal, or damage to the electrical system are the situations that most often require temporary relocation, which many policies cover as additional living expense.

Will my hardwood floors be ruined?

Not necessarily. Hardwood that has cupped can often be dried and refinished if the response was fast, sometimes using specialised floor drying mats. Boards that have crowned, buckled or delaminated usually need replacing. The assessment depends on the moisture readings, not the appearance.

Should I call my insurer or a restoration company first?

Call the restoration company first if water is still active, because delaying mitigation can itself jeopardise a claim. Most policies require you to take reasonable steps to prevent further damage. Notify the insurer immediately afterward.

What is an Assignment of Benefits?

It lets the restoration company bill your insurer directly instead of you paying up front and waiting for reimbursement. It is common and convenient, but it does assign your claim rights for that work, so read what you are signing and ask what it covers.

How do I know when the building is actually dry?

By documented moisture readings against a target, not by touch and not by the calendar. A reputable company takes daily readings and hands you the log. If nobody can tell you the target moisture content or show you the readings, the drying was not verified.

What should I do in the first hour?

Stop the water at the main shutoff if you can do it safely, cut power to affected areas at the breaker, photograph everything before touching it, then call for extraction. Do not run your HVAC system, which can carry moisture and spores through the rest of the building.
