Chimney Cleaning
Creosote is the fuel a chimney fire runs on. Chimney cleaning removes it from the flue, smoke shelf, and smoke chamber before it has a chance to ignite.
★ Overview
What chimney cleaning actually involves
Wood does not burn completely. What is left goes up the flue as unburned particles and condensing vapour, and it settles on the cooler surfaces near the top as creosote. Early on it is dusty and easy to brush away. Left alone it hardens into a tarry layer, then into a shiny glaze that has to be treated chemically or removed mechanically.
That progression is the whole reason chimney cleaning exists. The National Fire Protection Association identifies failure to clean, principally creosote from solid-fuel heating equipment, as the leading contributing factor in home heating fires. Dry creosote ignites at roughly the same temperature as paper.
A cleaning covers more than the flue itself. Soot collects on the smoke shelf, in the smoke chamber, and around the damper, and those areas affect how well the fireplace drafts.
★ Scope of work
What is included
Full flue sweep
Brushed from top to bottom or bottom to top depending on access, using rods and brush heads sized to your flue.
Smoke chamber and smoke shelf
The area above the damper collects the heaviest deposits and is skipped surprisingly often. It gets cleaned.
Damper and throat
Cleared and operated so it opens and closes properly once the soot is off it.
Firebox
Brushed down and vacuumed, with the surrounding hearth left clean.
Dust containment
Drop cloths and a HEPA-filtered vacuum at the fireplace opening. A cleaning should not leave a grey film on your mantel.
Condition report
Creosote stage, blockages, and anything we noticed about the liner, crown, or cap, with photos where useful.
★ Warning signs
Signs you may need this
- A thick, sticky, or shiny black layer visible inside the flue
- A strong smoky or tar-like smell from the fireplace, worst in warm weather
- Smoke rolling into the room when you first light a fire
- Fires that are hard to start or will not stay going
- Black flakes or soot falling into the firebox
- A full heating season since the last cleaning
Seeing more than one of these usually means the underlying issue has been developing for a while. It is worth having looked at rather than watched.
Why this is not worth deferring
The widely used industry rule of thumb is that once creosote reaches about an eighth of an inch, the flue should be cleaned. That is roughly the thickness of two stacked coins, thinner than most people expect, which is why the visual check matters more than the calendar. We cover the thresholds in detail in how often you should clean your chimney.
Cleaning also restores draft. Deposits narrow the usable diameter of the flue and roughen its walls, and a fireplace that has been fighting a restricted flue usually burns noticeably better afterwards.
★ Our process
How we handle it
STEP 01
Set up and protect
Drop cloths down, vacuum sealed at the opening, path from door to fireplace covered.
STEP 02
Sweep the system
Flue, smoke chamber, smoke shelf, damper, and firebox, using brush sizes matched to the flue.
STEP 03
Inspect while it is clean
A clean flue is the only flue you can properly assess. We look at liner condition, joints, and blockages.
STEP 04
Report and clear out
You get the findings, photos where relevant, and a hearth left as clean as we found it.

★ Questions
Chimney Cleaning FAQs
More on the full FAQ page.
NFPA 211 calls for an annual inspection, with cleaning done when it is needed rather than on a fixed schedule. A household burning a few cords a season often needs yearly cleaning; occasional weekend fires may not. The inspection is what decides it.
It should not be. Between drop cloths and a HEPA vacuum sealed at the fireplace opening, soot stays in the equipment. If a company does not mention containment, ask about it.
Brush kits exist, and light soot in an easily reached flue is within reach for a careful homeowner. What DIY does not get you is the inspection, creosote stage, liner cracks, gaps at joints, which is usually the more valuable half of the visit.
A single straightforward flue typically runs about an hour to ninety minutes including setup and inspection. Heavy glazed creosote or multiple flues take longer.
