Quick answer
Wood stoves and inserts burn hotter and longer than open fireplaces, so they build creosote faster. Have the liner swept and inspected every year (sometimes mid-season), check door gaskets and glass, remove ash regularly, and burn only dry wood with enough air.
Before the season
- Professional sweep and liner inspection
- Check door gaskets (a dollar bill closed in the door should not slide out easily)
- Inspect firebricks and baffle
During the season
- Remove ash before it reaches the bottom of the door opening, into a metal container with a lid
- Avoid overnight smoldering burns with the air shut down
- Watch the glass — rapid blackening means wet wood or not enough air
Inserts need a full liner
A fireplace insert should be connected to a full-length stainless liner sized to the stove. Inserts vented into the old fireplace flue without a liner draft poorly and build creosote quickly.

How often should a wood stove chimney be cleaned?
At least once a year, and more often with heavy daily use — many stove owners need a mid-season check.
