Heavy wood heat through a long winter. Is the flue keeping up?
- A stove or fireplace running daily for months
- Creosote visible within one season of a sweep
- A masonry repair list that keeps waiting for a warm week
Why it happens in Michigan: Michigan pairs one of the Midwest's older housing stocks with lake-effect winters that bury it. Wet lake snow packs against windward masonry and melts into it; the freeze does the rest. Windward-side damage worse than leeward is the signature here.
What fixes it, and what it costs
Serious burn hours mean the annual sweep is a floor: heavy burners here often need a mid-season look, and glazed creosote handled as its own job. The masonry calendar is the other constraint: mortar will not cure through the deep cold, so crown and joint work found in autumn books for spring, and the smart inspection happens early enough to beat that queue.
- Standard single flue, wood-burning
- $170–$320
- Stage three glazed creosote
- $400–$900
