Do Chimney Sweeps Need a License? Certification and Rules
Do you need a license to be a chimney sweep? Business licences, state and local contractor licences for chimney repair and liners, certification vs licensing,…
In this article
In most of the US, chimney sweeps need a business licence but there's no special state licence just for sweeping. However, some states and cities require a contractor or home improvement licence, especially for repairs, masonry or liner installation. Industry certification (such as CSIA) is voluntary but widely expected.
Rules vary by location; check with your state contractor board and city.
