Chimney sweeps are professionals who clean and maintain chimneys to ensure they function safely and efficiently. Their work involves removing soot, debris, and blockages that can cause chimney fires or carbon monoxide buildup. Regular cleaning is essential for homes with fireplaces or wood-burning stoves. Historically, many chimney sweeps were children, often employed in the Industrial Revolution era, due to their small size, which allowed them to climb into narrow chimneys. Today, chimney sweeps are trained adults who use specialized tools and techniques to perform their jobs safely and effectively, promoting fire safety in homes.
