What work did a chimney sweep do?

A chimney sweep was responsible for cleaning and maintaining chimneys to ensure they functioned properly and safely. This involved removing soot, debris, and blockages from the chimney flues to prevent chimney fires and improve airflow. In historical contexts, especially during the 18th and 19th centuries, many chimney sweeps were children who faced harsh working conditions. Their work was crucial for preventing dangerous buildup and maintaining the efficiency of fireplaces and stoves.
