Seasoned Firewood in Winnebago County: Buying and Burning

What you burn decides how much smoke you make and how fast creosote builds in the flue. Wet wood burns cool, and the smoke it makes condenses on the chimney walls. This guide covers what dry firewood is, how to season it, what to keep out of the fire, and the Illinois rules on moving wood. It supports our wood stove and insert service page.

A note on scale first. Few Winnebago County homes burn wood for heat: the Census (ACS 2020-2024) counts 169 homes whose main fuel is wood, while 83.5% of occupied homes heat with gas. Most wood burning here is an occasional fire in a masonry fireplace, plus a smaller number of stoves and inserts. The advice is the same for both.

How dry is dry

A wood moisture meter costs little and takes the guesswork out. Split a log, push the pins into the fresh face and read the number. Under 20 percent is the target. Wood that reads higher will hiss, spit, smoke and blacken the glass on a stove door. The EPA page says to season wood at least six months, and up to a year for hardwoods. Store it off the ground, with the top covered and the sides open to the wind. A tarp pulled down over the whole stack keeps moisture in.

EPA stopped updating its Burn Wise pages on October 30, 2025 and keeps them as a historic record. The advice has not changed in the sources we found, but the site will not be revised.

What never goes in the fireplace

That includes painted or stained scrap, pallets of unknown origin, cardboard and wrapping paper. They give off chemicals and burn hot and fast. A flue coated with creosote from wet wood is a fire risk; see how to remove creosote and signs of a chimney fire.

Where to buy firewood in the county

Buy from a seller who can say when the wood was cut and split. “Seasoned” on a sign is a claim, not a measurement. Bring your meter and test a few pieces from the middle of the pile. A cord is a stacked volume, so ask what is delivered (a cord, a face cord or a truckload) and get the quantity in writing. We have not researched any individual firewood seller and name none here.

Signs wood is ready, and how to store it

A meter is the real test, but some signs help while you shop. Seasoned wood is usually lighter than green wood of the same size, the ends are cracked and gray, and two pieces knocked together ring rather than thud. Green wood is heavy, has bright, damp ends and may ooze at the cut. Stack it with the bark side up on a rack or pallets so air moves under it, and keep it away from the house wall, where it attracts insects. Bring in a day or two of wood at a time. A load that has sat in a warm garage dries a bit more, but the real work is done outdoors over months.

If you buy the wood in fall, expect it to need more drying. That is the reason to order for next winter in spring, and to ask for a stated drying time. For a fireplace used a few times a winter, kiln-dried bundles cost more per fire but remove the guesswork.

Illinois and emerald ash borer: the rules on moving wood

Emerald ash borer (EAB) is a beetle that kills ash trees and travels in firewood. The rules have two layers, and they are easy to mix up:

• Inside Illinois. The Illinois Department of Agriculture says it no longer has regulations or restrictions on moving regulated ash material within the state, and that there is no longer a quarantine within Illinois (its FAQ, dated November 30, 2022). University of Illinois Extension says hardwood firewood is not regulated in Illinois and can move freely across the state.
• Out of Illinois. The Department of Agriculture's firewood page says it is against quarantine regulations to move any hardwood firewood out of the State of Illinois. If you camp or have a cabin in another state, leave your wood at home.

Even where it is legal, the advice is the same. Illinois Extension says to burn firewood where you buy it, and USDA APHIS repeated “buy firewood where you burn it” on October 1, 2026, warning that moving wood even short distances can carry EAB and other pests. A load from a few counties away is still moving wood. Buy local, and do not bring in wood from a relative's property across the state.

An older anti-firewood-movement page we found (dated 2009) lists county restrictions in northern Illinois. The state's own pages say the interior quarantine has been lifted, so we treat that list as stale.

Burning rules and your chimney

Illinois EPA's open burning page covers campfires, bonfires and garbage; it does not address indoor fireplaces. City and village rules on outdoor fires are in outdoor burning rules in Winnebago County. In Rockford, a fireplace or wood-burning appliance cannot be a building's primary heat source. The Rockton code expressly allows burning wood in domestic fireplaces, provided no garbage is burned. If you are choosing a new appliance, read EPA-certified wood stoves.

Sweeping prices are on the cost page. Angi lists $150 to $300 for a wood stove sweep (national, July 10, 2026) and $129 to $381 for a chimney sweep. Dry wood stretches the time between sweeps. See how often to sweep.
