Chimney Sweep Certifications Explained

Chimney sweeping and dryer vent cleaning are crucial tasks in the fight to keep families safe from home fires. The best and most reliable chimney sweeps are certified by the Chimney Safety Institute of America (CSIA), indicating the highest level of specialized training and expertise in their field.


The Chimney Safety Institute of America offers training courses on guidelines, safety precautions for inspecting chimneys, and sweeping techniques. To become a Certified Chimney Sweep, you must pass two exams covering safety, policies, and procedures.

Closed Book Test
All prospects seeking certification must pass a closed-book exam, based on the course book Successful Chimney Sweeping and the most recent National Fire Protection Agency’s 211 fire codes. The exam must be completed in an hour or less.

Open Book Test
Additionally, prospects must also take an open-book test with questions based on the International Residential Code, where test-takers must bring their own book for the exam.

The CSS certification is valid for one year, and renewed each year for a minimal fee. Every 3 years, chimney sweeps must retest for continued certification.


In addition to being CSS certified, we are proud to be members of the National Chimney Sweep Guild. This non-profit trade association provides progressive services, encourages professionalism, and most importantly, ethical accountability. Members agree to abide by the NCSG Code of Ethics and submit to a set procedure designed to address any grievances a customer may have with a Chimney Sweep Guild Member. Noncompliance or other misdeeds could result in members having their guild membership revoked.
