Follow current warnings first
Use the National Weather Service Seattle for current weather information and your local authority for road closures. Do not cross floodwater or enter an unstable room to inspect damage. The cleanup discussion begins only when the property can be approached safely.
Record how water entered
A threshold, basement opening, wall penetration and drain backup are different clues. Record what was happening when water appeared, whether a drain was involved and which rooms are affected. Avoid diagnosing the cause from rainfall timing alone.
Ask about contaminated materials
Outside water may require different handling from a clean supply leak. Ask how the provider assesses contamination, contains the work area and decides which porous materials need removal. Read the first-steps guide before attempting cleanup.
Reduce recurrence after the assessment
Cleanup does not repair the source of outdoor entry. Ask which drainage, waterproofing or building repairs belong to another qualified business. Seattle homeowners can use the city’s drainage guidance; properties outside Seattle should consult their own authority.
Seattle context and official guidance
For weather and street-access considerations, use the Seattle property guide. In a heavy rain situation, review what to record about outdoor water entry.
