Cleaning Wood-Burning Fireplaces in Ontario Homes
Wood-burning fireplaces are common in Ontario homes from the Victorian and Edwardian eras through the 1970s and 1980s builds. A fireplace that's actively used creates specific cleaning challenges: soot, ash, glass door residue, and fine particulates that settle on surfaces throughout the room. Here's how to approach it.
What Cleaning Covers vs What Needs a Sweep
Professional house cleaning covers: Hearth (tile or stone in front of the firebox), mantel and surround, glass doors (soot and residue), ash removal from the firebox if it hasn't been done recently, and the surface-level cleaning of all nearby furniture and surfaces where fine ash settles.
Requires a chimney sweep: The interior of the chimney and flue. Professional house cleaners do not clean chimney interiors — this is specialist work requiring certified sweep equipment. WETT-certified chimney sweeps operate throughout Ontario and should inspect and clean the chimney annually if the fireplace is regularly used.
Ash Removal
Ash should be removed from the firebox using a metal ash scoop into a metal container — not a plastic bucket or regular garbage bag. Fine ash particles are electrostatically charged and will escape a normal bag. Always let ash cool for at least 72 hours before removing — hot embers can stay buried in ash for days.
Glass Door Cleaning
Fireplace glass collects creosote residue (the yellow-brown film from incomplete combustion). A paste of ash and water applied with newspaper works surprisingly well. Commercial fireplace glass cleaners with potassium hydroxide work faster. Do not use regular glass cleaner — it won't cut creosote.
