Mold & Air Quality
The Snohomish Health District provides residents with information on how to identify indoor air quality problems, which most commonly concern mold.
Molds are microorganisms that can be found virtually anywhere — both indoors and outdoors. They present a potential health concern, as they can cause allergies and respiratory infections, and can worsen certain illnesses, such as asthma.
The Puget Sound Clean Air Agency regulates and monitors outdoor air quality issues in Snohomish County, including air pollution caused by transportation, wood stoves and fireplaces, outdoor fires, yard care, and land use.
How to identify mold and other air problems
Testing for mold is usually not needed to solve the problem. If you think you have mold in your home, you can typically identify it by sight and smell. After you confirm the mold problem, you should wash away any mold with soap and water.
Other indoor air concerns include radon and asbestos.
How to prevent mold growth
The key factor to preventing mold in your home is moisture control, which you can easily do by eliminating the moisture source and increasing ventilation.
Check your home for any structural or plumbing issues that may be causing a leak as well as any humidity problems. If you find more than 10 square feet of mold in one area of your home, you may want to seek the help of an experienced contractor for removal.
If you are a renter with mold
The Washington Residential Landlord-Tenant Act, which describes the duties required of residential landlords and tenants, states that landlords must inform tenants about mold.
For mediation advice concerning landlord disputes over mold and other issues, the Volunteers of America’s Dispute Resolution Center of Snohomish and Island Counties may be able to provide help.
