Chimney Sweep in Sanford, FL

Creosote is not one substance. The first stage is a dry, dusty soot that brushes away. The second is hard flake and tar. The third is a glazed coating no brush will touch, which has to be broken down chemically or with rotary tools. Flue temperature and fuel moisture decide which one forms: exhaust that cools below its condensation point plates onto the tile, so fires that never bring the upper flue up to temperature leave their heaviest deposit near the top, where the masonry stays coldest. That is where a sweep concentrates its attention, and it is why the third stage matters out of proportion to its thickness, since glaze is concentrated fuel and a flue carrying it can burn hot enough to crack tile. If you suspect an active chimney fire, leave the home and call 911 before requesting chimney service.

Cleaning scope depends on the fireplace or appliance, the accessible vent path, and the buildup found inside it. An obstruction or damaged component may require separate work rather than more sweeping. Ask which passages the cleaning covers and whether an inspection or any proposed repair is a separate item before comparing estimates.

• What fuel does the fireplace or stove use?
• When was it last used and cleaned, if known?
• Have you noticed smoke in the room, odors, debris or animal sounds?
