Significant creosote build up on venting of a wood stove

How often does my chimney need sweeping?

Our rule of thumb: once a year or once a cord — whichever comes last.

How Often Does a Chimney Need Sweeping?

Our rule of thumb after thirty years in the trade: once a year or once a cord, whichever comes later. Buildup comes from the wood you burn, not the calendar. Burn three cords a winter? That’s a yearly sweep. Take four years to get through one cord? Then your sweep is every four years, and you’d rather hear that from us than pay to sweep a chimney that’s barely worked.

Dry wood holds the rule up

The rule depends on dry wood. Seasoned firewood burns hot and clean. That means a year or more split and under cover, and under 20% moisture if you own a meter. Wet wood burns cool and smoky, and cool smoke is what coats a chimney with creosote. Burn it all winter and you can need two sweeps a year. If your wood sizzles in the fire, that’s the sound of the problem. A moisture meter, about $25, is the cheapest chimney maintenance there is, and it costs less than a second sweep.

Gas or pellet?

Gas and pellet fireplaces don’t need a chimney sweep. Their yearly visit is a gas & pellet service.
