How Often Should I Clean My Chimney?
A general rule of thumb to follow is a chimney should be cleaned every 50 to 60 fires. Usage of 4 to 7 nights per week should be cleaned a minimum of twice per season.
If you notice an odd smell, it is usually due to creosote deposits in the chimney, a natural byproduct of wood burning. The odor is usually worse in the summer when the humidity is high or on rainy days when the air is heavy. A tight sealing, top mounted damper will also reduce this air flow coming down the chimney. It is also possible an animal is living in the chimney or has died in the chimney.
