Start with recurring moisture
Tell the provider where visible growth or odor occurs and whether there is a known leak, condensation issue or previous water event. Avoid disturbing the area to collect samples. This website cannot identify a mold species or assess health risk from a description.
Request the remediation scope
Ask how the business assesses the area, protects adjacent rooms and handles affected materials. Request the basis for any testing recommendation, who performs it and what the result can establish. No certification or health guarantee is implied by this page.
Repair the underlying moisture problem
Remediation and source repair are related but distinct tasks. Confirm responsibility for plumbing, drainage, ventilation or building-envelope repairs. The drying guide explains why finish appearance alone is insufficient.
Verify qualifications and limits
Use Washington L&I to check applicable contractor registration and discuss qualifications directly. Ask about excluded work and post-work documentation. Read EPA’s mold guidance and the hiring checklist before authorizing a contract.
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.
