Place a dropcloth over the area where the connecting pipe leads from the stove to the roof. This is the section of the stovepipe inside the house. Remove the connecting pipe. The procedure for disconnecting connecting stovepipes varies depending on design, so consult the manufacturer’s instructions.
Climb the ladder and remove the stovepipe from the roof, again following the manufacturer's instructions. Inspect each section of the pipe for corrosion and cracks, using a flashlight. If you find cracks, have them repaired. Cracks can allow sparks to escape, creating a fire hazard.
Pull a wire chimney brush through each pipe section to scrape away the creosote deposits. Repeat this step several times until all the creosote buildup is removed.
Reinstall the stovepipe sections and reconnect the connecting pipe.
