Water damage can happen suddenly — a leaking pipe, a broken water heater, a clogged drain line, a failed appliance, or storm-related intrusion.
In the Seattle & Eastside areas, moisture problems are especially common due to our rainy climate and older plumbing systems.

Knowing what to do in the first 10 minutes can prevent thousands of dollars in damage.
Here is a clear, step-by-step guide to follow the moment you discover water damage.

1. Stop the Water Source Immediately

Before anything else, prevent additional water from coming in.

If possible:

  • Turn off the main water supply

  • Shut off valves to toilets, sinks, and appliances

  • Stop running appliances

  • If it’s a roof leak, place a bucket or tub under it

2. Turn Off Electricity in the Affected Area

  • Shut off breakers

  • Avoid stepping in standing water near outlets

  • Do NOT use electronics on wet flooring

3. Take Photos and Document Everything (For Insurance)

Before cleaning, document:

  • All affected rooms

  • Areas of damage

  • The leak source

  • Any damaged items

4. Remove Standing Water

Use:

  • Towels

  • Wet/dry shop vacuum

  • Mops

Remove rugs or mats so moisture doesn’t get trapped.

5. Protect Your Belongings

Move items away from affected areas:

  • Furniture

  • Electronics

  • Clothing

  • Storage boxes

6. Start Drying Immediately

Drying must start within the first hour.

Use:

  • Fans

  • Dehumidifiers

  • Open windows (weather permitting)

Moisture hides under flooring and behind walls.

7. Check for Hidden Water Damage

Look behind or under:

  • Baseboards

  • Drywall

  • Cabinets

  • LVP/laminate flooring

  • Crawlspaces

  • Tile or carpet

8. Inspect for Structural Damage

Signs include:

  • Soft or warped flooring

  • Swollen baseboards

  • Sagging drywall

  • Stains or bubbling paint

  • Loose tiles

9. Call a Professional for Water Restoration

Professionals can:

  • Perform moisture readings

  • Open and dry walls safely

  • Prevent mold

  • Repair drywall/floors

  • Fix plumbing or leak sources

10. Schedule Repairs After Drying

Repairs may include:

  • Drywall

  • Insulation

  • Baseboards

  • Flooring

  • Painting

  • Cabinet repair

  • Fixing the original leak
