Long wet seasons cause mold in basements, attics and bathrooms.
Craftsman and Tudor homes with basements are common, along with many new townhomes and apartments. Many Seattle homes have converted basements or attached accessory dwelling units, so water damage often affects separate living spaces. Newer townhomes have stacked bathrooms and roof decks, where failed membranes and drains lead to leaks. Older homes in Ballard and Wallingford often sit on lots with poor drainage, where basements stay damp most of the rainy season.
Licensing in Washington: Washington requires contractors to register with the Department of Labor and Industries (L&I). Check the registration and bond on L&I's website.
