Quick answer

In the first 60 minutes of water damage: shut off the water at the main valve, cut power to wet areas at the breaker, and photograph and video everything before moving anything. Then call a restoration company — extraction and drying are the time-critical steps, because mold begins establishing at 24 hours. Move belongings up off wet flooring while you wait.

The First 60 Minutes of Water Damage: Your Complete Action Guide

Water damage emergencies are measured in minutes, not hours. The first 60 minutes after water appears in your home determine how much you'll pay, how quickly you'll recover, and — critically — whether your insurance claim will succeed.

This guide gives you the exact sequence of actions, written for homeowners in the middle of an emergency — not for contractors or insurance adjusters.

Minute 0–5: Stop the Water and Cut Power

Finding your water shutoff: The main water shutoff is usually located at the water meter (near the street or at the property line), under the kitchen sink, in the utility room, or in the crawl space. Know its location before an emergency. A standard residential shutoff can be turned off with your hand (gate valve) or requires a meter key (ball valve type).

Electrical safety: Do not enter a room with standing water if electrical outlets, floor-level wiring, or appliances are wet. Shut off the circuit breaker for the affected area before entering. If your electrical panel itself is wet or near the water, call your utility company — don't attempt to operate it.

Gas concerns: Water and gas infrastructure sometimes co-locate. If you smell gas in or near the affected area, leave the building immediately and call your gas company.

Minute 5–15: Document Everything

This step determines whether your insurance claim succeeds or fails.

What to photograph:

  • Standing water from multiple angles, showing depth
  • The source of water (cracked pipe, failed connection, damaged roof section)
  • Every affected room and surface
  • All furniture, appliances, and personal property showing water contact
  • Any visible structural damage (buckling floors, sagging ceilings)

Video walk-through: Do a narrated video walk-through of the entire affected area. Narrate what you see: "The water appears to be approximately 2 inches deep in the kitchen, extending into the hallway." This creates a timestamped record that photographs alone cannot.

The critical rule: Do NOT move, remove, or discard anything before photographing it. Insurance adjusters need to verify every damaged item. Moving items before documentation is one of the most common reasons claims are disputed.

Minute 15–30: Make the Critical Calls

Call #1: A restoration company — not a plumber

Most homeowners make the mistake of calling a plumber first. Plumbers fix the source of water — they do not extract water, dry structures, or document damage for insurance. A restoration company does all three simultaneously. For a full breakdown by scenario, see who to call for water damage — the correct order of calls.

Certified restoration companies can also coordinate emergency repairs to the water source while the restoration team extracts. This parallel approach saves critical time.

Call #2: Your insurance company

Open a claim immediately. You do not need to wait for an adjuster to visit before work begins — emergency extraction is necessary mitigation under your policy. However, you do need a claim number and verbal authorization before extensive work begins.

Tell your insurer:

  • The source of water (pipe, appliance, roof)
  • Rooms affected
  • Whether it's still actively leaking (or has been stopped)
  • That you've documented with photos/video

What to ask your insurer:

  • What's my deductible?
  • Do I have coverage for additional living expenses (ALE) if I need to leave?
  • Is sewage backup covered under my policy?
  • What's the process for authorizing contractor work?

Minute 30–60: Protect What You Can Safely Move

While waiting for the restoration team:

Safe to move:

  • Important documents (birth certificates, insurance policies, passports)
  • Prescription medications
  • Irreplaceable photos and keepsakes in waterproof containers
  • Portable electronics not near water

Floor protection: Place aluminum foil under furniture legs to prevent rust stains on carpet. Place wooden blocks under furniture legs sitting on wet hardwood — trapped moisture accelerates warping and can be harder to document once cleaned up.

Rugs and mats: Remove saturated throw rugs from hardwood flooring — they trap moisture and accelerate wood cupping. Do NOT remove wall-to-wall carpet installed over subfloor — this needs professional extraction equipment and documentation.

What NOT to Do in the First 60 Minutes

These mistakes are consistently cited by claims adjusters as reasons for reduced settlements:

  1. 1Don't use a shop vac or household fans for Category 2/3 water — improper circulation spreads contaminated water and airborne particles.
  2. 2Don't throw away anything damaged — adjusters need to see items. Take them to your garage or porch if needed, but don't dispose of them.
  3. 3Don't sign anything a contractor hands you at the door — Emergency-door contractors after storms are common. Never sign Assignment of Benefits (AOB) or any authorization form without reading it completely.
  4. 4Don't apply bleach to drywall — Surface bleach kills visible mold but doesn't penetrate. It also masks moisture that restoration teams need to identify with moisture meters.
  5. 5Don't delay because it "seems to be drying" — Water wicks through building materials invisibly. A wet-feeling floor can have thoroughly saturated joists, subfloor, and insulation below it that will grow mold within 24 hours.

Understanding the Restoration Team's First Steps

When certified restoration pros arrive, they'll:

  1. 1Assess and categorize — Identify water category (1/2/3) and class of damage (extent of saturation per IICRC S500 standard)
  2. 2Moisture mapping — Thermal imaging cameras and moisture meters identify hidden wet areas in walls, ceilings, and floors
  3. 3Extraction — Truck-mounted or portable extraction units remove standing water and surface moisture
  4. 4Drying plan — Industrial air movers and dehumidifiers are positioned per their moisture map
  5. 5Documentation — Every measurement, photo, and action is logged for your insurance claim

Your Rights as a Homeowner

You have the right to:

  • Choose your own restoration contractor (insurance companies cannot mandate their preferred vendor)
  • Request a written scope of work before any work begins
  • Get a second estimate (for non-emergency work)
  • Receive a copy of all moisture readings and drying logs
  • Dispute an insurance estimate via your policy's appraisal clause

The first 60 minutes are critical — but knowing your rights throughout the restoration process is equally important.

Frequently Asked Questions

What is the very first thing to do when water damage occurs?
Shut off the water source immediately. For a burst pipe or appliance, turn off the supply valve. If you cannot find the source, shut off your home's main water supply (typically near the water meter or in the utility room). Then cut power to affected areas at the circuit breaker -- never enter standing water if electrical outlets or appliances could be submerged.
Can I use household fans and dehumidifiers to dry my home after water damage?
For Category 1 (clean water) on hard surfaces only, household fans can help while waiting for professionals. However, consumer equipment is 10-15x less powerful than industrial air movers used by certified restoration companies. For Category 2 or 3 water (gray water, sewage, or flood water), using household fans can spread contaminated air and particles throughout your home.
What should I NOT do in the first hour after water damage?
Do not: use a shop vac on gray or sewage water (spreads contamination); throw away damaged items (adjusters need to inspect them); sign anything handed to you at the door by an uninvited contractor; apply bleach to wet drywall (does not penetrate and masks moisture); or assume the damage is minor because it looks small -- water migrates into wall cavities invisibly.
How long do I have before water damage causes mold?
Mold spores can begin germinating within 24-48 hours of water damage under warm, humid conditions. This is why starting professional drying within the first 24 hours is critical. If structural drying begins quickly with industrial equipment, mold growth can typically be prevented even in organic building materials like wood framing and drywall.
How do I know if the water damage is Category 1, 2, or 3?
Water category determines cleanup protocol and cost. Category 1 (clean water): originates from a potable supply line, fresh toilet supply, or rainwater with no contamination — the lowest cost to remediate. Category 2 (gray water): contains biological contaminants but not sewage — washing machine overflow, dishwasher backup, toilet bowl water (no feces). Category 3 (black water): sewage, groundwater flooding, or any water that has been sitting for more than 48–72 hours regardless of original source (standing water grows bacteria rapidly). If you are unsure, treat as Category 2 or 3 until a certified technician categorizes it. Category 3 requires full PPE, HEPA air scrubbing, and regulated disposal of all porous materials — never attempt Category 3 cleanup without professional equipment.
