What this covers
Chimney sweeping removes the soot and creosote that build up inside a flue each time it is used. The sweep lays drop cloths, seals the fireplace opening with plastic and a vacuum so dust stays out of the room, runs rotary or wire brushes the length of the flue, and cleans the smoke chamber, damper and firebox. A careful sweep looks at the liner, crown and cap while there and tells you what they found, since cracks and heavy glazed creosote need more than a sweep.

Questions people ask
How often should a chimney be swept?
Common practice is a yearly inspection, with sweeping whenever the buildup calls for it. Wood burned often or burned wet builds creosote faster.
What is creosote?
A tar-like residue from wood smoke that condenses in the flue. It is flammable, and heavy or glazed layers need special removal.
What if damage is found?
Cracked liners, a broken crown or loose brick are repaired by a masonry or chimney company. After a chimney fire, the flue is inspected before it is used again.
