Poor servicing can lead to a house fire
A chimney fire is a fire that burns inside a chimney or flue, usually caused by a build-up of creosote — a highly flammable residue produced when wood or other fuels burn. When smoke travels up a cooler chimney, oils and particles condense on the inside walls and form creosote. Over time, this layer thickens. If temperatures get high enough, the creosote can ignite.
Common causes
Infrequent chimney cleaning
Burning wet or unseasoned wood
Poor airflow or ventilation
Blocked flues
Excessive soot and creosote build-up
Signs of a chimney fire
Loud cracking or popping sounds
Dense smoke
Flames or sparks coming from the chimney top
A roaring sound like a freight train
A chimney fire can:
Crack chimney liners or masonry
Spread into walls, ceilings, or the roof
Cause house fires
Increase carbon monoxide risk
Prevention
Have the chimney professionally swept regularly
Burn dry, seasoned wood
Ensure good ventilation
Use the correct fuel for the appliance
A well-maintained chimney greatly reduces the risk.
Benefits of Regular Chimney Sweeping
Reduces fire risk
Protects your home from smoke and carbon monoxide damage
Improves heating efficiency
Provides peace of mind
Recommended Cleaning Frequency
At least once a year
Ideally at the end of the burning season
Twice a year if the appliance is used heavily and only wood is burnt
