Licensing
Do you need a license in Delaware?
Chimney sweeping is generally not a separately licensed trade in Delaware, though some municipalities may require local business registration. Work that involves structural masonry repairs or modifying venting may fall under broader building or trade rules. A NISCR certificate is a professional credential demonstrating training and safety knowledge, not a government license. Always verify current local registration and any applicable building 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.
Local demand
The chimney sweep market in Delaware
Delaware's cold winters keep wood stoves and fireplaces in regular use, and the state's historic homes in Wilmington, New Castle, and coastal towns often have aging masonry chimneys that need cleaning and inspection. Creosote buildup raises chimney-fire risk during heating season, sustaining demand for skilled sweeps.

Curriculum
What you’ll learn
- Identify the three stages of creosote buildup and select the correct removal method — brushing, rotary, or recommending specialist treatment — for each.
- Perform a level-1 inspection of a readily accessible flue, connector, and appliance, and document findings in a clear written report.
- Inspect chimney caps and spark arrestors for damage, blockage, and animal or debris intrusion, and recommend repairs.
- Test damper operation and seating to confirm proper draft and a positive seal when the appliance is not in use.
- Recognize the distinct hazards of wood-burning versus gas appliances, including creosote ignition risk and carbon-monoxide and acidic-condensate concerns on gas flues.
- Set up and break down the job to protect the home — drop cloths, dual-HEPA vacuum containment, and soot control around the firebox.
