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

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