If you don't clean your chimney regularly, soot will accumulate around the flue causing an inability to draw smoke upwards. The smoke will then be directed to your room leaving black soot on the walls, furniture, and carpeting. It causes permanent staining around the chimney in some cases.
The National Fire Protection Association Standard 211 says, "Chimneys, fireplaces, and vents shall be inspected at least once a year for soundness, freedom from deposits, and correct clearances.
How do we clean chimneys?
Chimney sweeps use a heavy metal bristled brush to clean your chimney. These tools are long rods, with the bristles located at the very tip. Professional chimney sweeps will also be outfitted in gloves, goggles, and masks to protect themselves from the soot and ash.
