Licensing
Do you need a license in Washington?
Dryer vent cleaning is generally not a licensed trade in Washington and is a low-barrier service to start, though a local business license usually applies where you operate. This is general guidance only, so confirm current city, county, and state requirements before advertising paid services.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.

Curriculum
What you’ll learn
- Perform a full pre-cleaning inspection of the dryer, transition duct, and vent run to locate lint buildup, kinks, crushed sections, and improper materials.
- Identify and correct code-violating ductwork such as foil-foil flex, plastic transition hoses, and runs that exceed manufacturer length limits.
- Select and operate the right tools — rotary brush-and-rod systems, compressed-air whips, and HEPA vacuums — for the duct length, material, and routing.
- Measure airflow and static pressure before and after cleaning to verify the system meets performance targets and document the improvement.
- Safely access and service rooftop, sidewall, and shared multi-unit vent terminations, including replacing damaged or screen-clogged exterior hoods.
- Recognize the warning signs of a fire hazard — scorching, excessive drying times, overheating shutoffs — and advise the customer on corrective action.
