Licensing
Do you need a license in Maryland?
Dryer vent cleaning is generally not a separately licensed trade in Maryland, making it a low-barrier entry point, though a local business license is typically required to operate. If work extends into modifying vent routing or building structure, additional rules could apply. Your NISCR DVC certificate is a professional credential, not a government license, so verify current local business licensing requirements before working.
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.

The dryer vent cleaning market in Maryland

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.
