Licensing
Do you need a license in Delaware?
Dryer vent cleaning is generally not a separately licensed trade in Delaware and has a low barrier to entry, though a local business license may be required depending on your municipality or county. A NISCR certificate is a professional credential that signals training and safety knowledge, not a government license. Always verify any current local business requirements before offering 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. Licensing rules change and vary by city and county. Always confirm current requirements with your state licensing board before performing work.

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.
