Wood-Burning Stove Maintenance: Your Pre-Winter Checklist

A step-by-step guide to keeping your home safe, warm, and efficient.

The first hard frost in North Idaho never sends a calendar invite. One morning it’s just there — and if your wood-burning stove isn’t ready, you’re troubleshooting in the cold instead of enjoying the fire.

That’s why late summer is the sweet spot for stove maintenance. Start in August or September and you’ve got time to clean, inspect, and fix anything that needs attention before burning season — no rushed repairs, no waiting weeks for a service call in the middle of everyone else’s emergency.

Start at the Top: Inspect the Chimney First

Your chimney is the gateway for smoke to leave your home safely, so it’s the first place to check. Remove the chimney cap and take a close look inside. If you notice a buildup of ash or soot around 1/4” thick or more, it’s time for a professional chimney sweep. Creosote buildup is a serious fire hazard, so addressing it before firing up your heat source is critical.

Check the Air Intake — Your Stove Needs to Breathe

Next, make sure nothing is blocking your outside air intake. Your appliance needs proper ventilation to burn efficiently and safely. A blocked intake can lead to poor fires or even dangerous backdrafts into your living space.

Test Door Gaskets With a Dollar Bill

Take a look at all the gaskets and door seals on your appliance. Are they cracked or worn? A simple “dollar bill test” can help you check: close a dollar bill in the door and try to pull it out. If it slides out easily, your gasket may need replacing. A tight seal keeps your stove efficient and safe, and prevents heat from escaping.

Burn the Right Wood: Moisture Matters

Not all firewood is created equal. Use a moisture meter to check your logs – anything above 19% moisture is too wet for good burning. Wet wood produces more smoke, builds up creosote faster, and doesn’t heat your home as effectively. Stick to seasoned, dry wood for the best fires.

If your current stove struggles even with good, dry wood, it may be the stove rather than the fuel. Modern wood, gas, and pellet stoves burn dramatically cleaner and hotter than units from a few decades ago.

Look Inside: Combustor, Fire Bricks, and Rust

If your stove has a catalytic combustor, now is the time to inspect and service it according to manufacturer guidelines. Also, check fire bricks for cracks or warping, and inspect your stove for rust or other damage. Ensuring these components are in good shape will help your appliance last for years and operate safely.

The Final Once-Over

Before you light that first fire, run through the rest of the list:

• Clean the glass so you can enjoy that beautiful fire.
• Test dampers and air vents to make sure they open, close, and seal properly.
• Check the floor and walls around your stove for heat-related wear or damage.
• Make sure your smoke and carbon monoxide detectors are working.
• Proper clearances from walls and furniture are also critical for safety.

When to Call in a Professional

Even a thorough DIY pass has blind spots. A certified technician can catch hairline cracks, venting issues, and early creosote problems that are easy to miss — and a quick service visit costs a lot less than a midwinter breakdown.

Take these steps now and you’ll skip the last-minute scramble, keep your home safe, and enjoy worry-free fires all winter. And if your checklist turns up something you’d rather have an expert look at, give us a call — we’re happy to take a look before the first chilly evening does it for you.
