Cleaning Around a Wood-Burning Fireplace
Ontario's colder climate and the aesthetic appeal of wood-burning fireplaces mean that a significant portion of the province's housing stock — particularly older homes — includes functional wood-burning fireplaces that are used seasonally. Fireplaces create a specific and somewhat specialized cleaning environment: ash, soot, smoke residue, and the creosote buildup in the flue all require specific approaches.
What Homeowners Handle
Ash removal: Wait at least 24 hours after the last fire before removing ash — embers can remain hot for far longer than expected. Use a metal ash bucket with a tight-fitting lid, never a plastic container or cardboard box. A small ash vacuum (designed for fine ash) is cleaner than a shovel for most applications. Leave a thin layer of ash (1–2 cm) on the firebox floor — it acts as an insulating bed that helps fires start more easily.
Hearth cleaning: The brick or stone hearth surround accumulates soot and ash residue. A mild solution of dish soap and warm water applied with a stiff brush removes most surface grime. For heavier soot staining: a paste of cream of tartar and water applied and left 5 minutes before scrubbing, or a commercial brick cleaner.
Glass doors: Fireplace glass doors blacken over time from creosote and soot. When cool, clean with a damp newspaper dipped in ash (the mild abrasive in the ash cuts through the residue) or a commercial fireplace glass cleaner.
What Chimney Sweeps Handle
Creosote buildup in the flue, chimney cap condition, flue liner integrity, and damper operation are all the domain of WETT-certified chimney professionals (WETT = Wood Energy Technology Transfer, Canada's certification standard). Ontario fire codes and home insurance policies typically require annual inspection of working fireplaces. Do not attempt to clean the flue yourself — disturbing creosote without containment creates a significant soot mess and is a health hazard.
