The wood you burn decides how clean your chimney stays. Green or damp logs burn cool and smoky, and the smoke leaves creosote behind. Dry hardwood burns hot and leaves very little.

What seasoned means
Seasoned wood has dried for at least six months, and ideally a year or more, until moisture falls below about twenty percent. It looks gray at the ends with cracks, sounds hollow when two pieces are knocked together and feels light for its size.
Best woods for Connecticut
| Wood | Why it works |
|---|---|
| Oak | Long, steady burn, needs a full year to dry |
| Maple | Good heat and widely available |
| Ash | Burns well, dries fast |
| Birch | Easy to light, burns quickly |
Storage that works
- Stack off the ground on a rack or pallets
- Cover the top, leave the sides open for airflow
- Keep at least a few feet from the house to avoid pests
- Bring a few days of wood inside before burning
The EPA Burn Wise program has a simple guide to wood moisture and cleaner burning, and CT DEEP tracks air quality and wood smoke advisories. A yearly sweep from our crew keeps any leftover creosote in check. See our chimney cleaning overview.
What Seasoned Firewood Really Means
Seasoned firewood is wood that has dried until its moisture content is around 20 percent or lower. Freshly cut wood can be 40 to 60 percent water. Burning wet wood wastes heat boiling off water, produces a smoky, cooler fire and deposits creosote in the chimney, which is the fuel for chimney fires.
How to Tell if Wood Is Dry
- Ends have cracks radiating from the center
- Pieces are light for their size
- Bark peels easily
- Two pieces knocked together make a hollow clack
- A moisture meter reads under 20 percent
Best Woods for Connecticut Fireplaces
Oak, hickory, ash and maple are dense hardwoods that burn hot and long. Birch and cherry are fine too. Softwoods such as pine burn fast and leave more resin. All woods need to be dried, and hardwoods typically need 6 to 12 months while softwoods need around 6.
Storing Firewood
- Stack off the ground on pallets or rails
- Cover the top but leave the sides open for air
- Keep the stack at least a few feet from the house to avoid pests
- Face the stack toward the sun and prevailing wind
What Never to Burn
Avoid pressure treated lumber, painted or stained wood, plywood, trash, cardboard and Christmas trees. They release toxic fumes or flare up and damage the flue.
Frequently Asked Questions
How long does it take to season wood
Six months to two years depending on species and splitting.
Can I buy kiln dried wood
Yes. It burns well but costs more.
Does seasoned wood prevent chimney fires
It greatly reduces creosote but does not replace annual cleaning.
