A chimney sweep is a professional who specializes in cleaning and maintaining chimneys. This can include removing soot and other debris that can build up inside the chimney, as well as checking the chimney for any damage or other issues that may need to be repaired. In the past, chimney sweeps were often viewed as being a somewhat unusual or even eccentric profession, but today they are an important part of maintaining the safety and efficiency of a home’s heating system.
