Seasoned vs. Green Firewood: What to Burn
The wood you burn matters more than almost anything else for a safe, efficient fire. Seasoned wood burns hot and clean; green (wet) wood smokes, wastes heat, and coats your flue in creosote.
What “seasoned” means
Seasoned firewood has dried for at least six months to a year, down to about 20% moisture. It lights easily, burns hot, and produces little smoke.
How to spot seasoned wood
- Cracks radiating from the ends
- Lighter weight than fresh-cut wood
- A hollow “clunk” when two pieces knock together
- Grayish, dull color rather than fresh and green
Why green wood is a problem
Wet wood spends its energy boiling off water instead of making heat. The cool, smoky burn deposits creosote fast — raising your chimney-fire risk.
Burning smart keeps your flue cleaner longer. When it’s time for a sweep in North Aurora, call the Fox brothers — see our chimney sweep page.
