Chimney Cleaning in Oshawa
Chimney cleaning and chimney sweeping describe the same work, but homeowners searching for cleaning are usually reacting to something: a smell, a smoky room, a bird, or an insurance letter. We treat it that way — the visit starts with finding out why you called, then removes the deposit causing it.

What we do
Chimney Cleaning in Oshawa — how it works
Cleaning covers three deposits. Soot is light and powdery and brushes away. Stage 2 creosote is hard and flaky and needs a rotary head. Stage 3 is glazed tar that has to be chemically modified first, then mechanically removed. Anyone quoting one flat price without seeing the flue is guessing.
Signs you need this service
- A smoky or tar smell in the room, especially in humid weather
- Smoke rolling out of the firebox opening when you light a fire
- Visible glaze, tar or thick black buildup in the flue
- Reduced heat output from a wood stove or insert
- Animals, nesting material or leaves in the chimney
- A dryer or furnace vent sharing the same chase
What's included
- Firebox, smoke shelf and smoke chamber cleaning
- Damper operation check and adjustment
- Cap and screen cleaning while on the roof
- Animal or nest removal where accessible
- Same-day photo documentation

Local knowledge
What this looks like around Oshawa
Ajax and rural King properties that burn cordwood as real heat can build a Stage 2 deposit in a single winter. Those homes are on a strict annual cycle with us and it is not optional.
Suburban Oshawa homes that burn a dozen fires a year usually only need soot removal, and we will tell you that rather than selling a treatment you do not need.
FAQs
Questions homeowners ask us
How often should a chimney be cleaned?
Annually for any wood-burning appliance used through the season, every two years minimum for a gas appliance in a masonry flue, and annually for pellet appliances. In Ajax and rural King where wood is a primary heat source, annually is the floor, not the target.
Can I clean my chimney myself?
You can brush the accessible section, but you cannot camera-scope the flue, grade creosote, verify clearances to combustibles or produce a report your insurer will accept. The inspection is the valuable half of the visit.
Why does my chimney smell in the summer?
Humidity reactivates creosote odour, and negative pressure in an air-conditioned house pulls that air down the flue into the room. Cleaning fixes the source; a top-sealing damper fixes the pressure path.
Do you clean pellet stoves?
Yes. Pellet appliances need the exhaust path, combustion blower and heat exchanger cleaned annually or they lose efficiency and start throwing pressure-switch faults.
