Year-Round Chimney Maintenance Schedule

Most Kansas City homeowners only think about their chimney when they’re cozying up to the first fire of the season. That’s usually around late October when our temperatures start that sharp drop. But here’s the thing: your chimney needs attention even when you’re not using it.

Spring: The Best Time for Your Annual Inspection

April and May are perfect months to get your chimney checked out. You’re done burning for the season, and the weather’s finally cooperating enough that technicians aren’t dealing with ice or sweltering heat.

This is when you’ll want a Level 1 inspection at minimum. A certified chimney sweep will check for creosote buildup, look for any structural damage that might’ve happened during winter, and make sure your cap and crown are still doing their jobs. After a typical KC winter where we swing from 15 degrees to 50 and back again in the same week, freeze-thaw cycles can wreak havoc on masonry.

Springtime inspections also let you tackle any repairs before they become expensive emergencies. Found some cracked flue tiles? You’ve got all summer to fix them. Water stains appearing on your ceiling near the chimney? Better to address that now than wait until next December when every chimney company in town is booked solid.

Summer Maintenance Nobody Talks About

People forget that chimneys exist during summer. Big mistake.

June through August is actually prime time for chimney repairs and waterproofing. The masonry needs to be completely dry before you apply water repellent, and our humid KC summers eventually give way to some decent stretches of dry weather. Waterproofing can save you thousands down the road because water is your chimney’s worst enemy, even worse than fire.

Summer’s also when you should check that chimney cap. Birds love nesting in chimneys during spring and early summer, and a missing or damaged cap is an open invitation. I’ve seen everything from birds to squirrels to raccoons make themselves at home. And if you’ve ever dealt with chimney swifts, you know they’re federally protected, which means you’re stuck with them until they decide to leave.

While you’re up there (or while your sweep is up there, don’t go climbing on your roof), make sure the flashing is still sealed tight. That’s the metal piece where your chimney meets the roof. It takes a beating from our summer thunderstorms, and even small gaps can let water pour into your home.

Fall: Getting Ready for Burning Season

September is go-time. This is your last chance to handle anything that came up during your spring inspection that you’ve been putting off all summer.

If you burn wood regularly, you’ll want a cleaning every year. Gas fireplace users can usually stretch it to every other year, but you should still get eyes on it annually. The National Fire Protection Association recommends annual inspections regardless of fuel type, and honestly, they’re not wrong. Problems don’t care whether you burn wood, gas, or pellets.

October is when everyone suddenly remembers they have a chimney. Don’t be that person scrambling for an appointment. By mid-October, most chimney companies are running two to three weeks out, sometimes longer. That first cold snap hits, everyone tries to light a fire, and half of them discover problems they should’ve addressed months ago.

Check your firebox for cracks or damage. Make sure your damper opens and closes smoothly. If you’ve got a gas fireplace, test it before you really need it. Nothing’s worse than planning a cozy evening by the fire only to discover your pilot won’t stay lit.

Winter: The Monitoring Season

From November through March, you’re mostly in observation mode. You’re using your fireplace or stove, so you’ll notice if something’s off.

Pay attention to how your fires burn. Struggling to get them started? Smoke backing up into the room? That’s not normal, and it usually means either a blockage or a draft problem. Could be as simple as forgetting to open the damper (happens more than you’d think), or it could signal something more serious like creosote buildup restricting airflow.

After ice storms, which we typically get at least once or twice each winter, take a look at your chimney from the ground. You’re checking for obvious damage like missing bricks or a cap that’s been knocked loose. Don’t climb up there yourself when it’s icy out. That’s a good way to end up in the ER instead of by the fireplace.

Keep an eye on your firewood moisture content too. Burning wet or green wood creates way more creosote, which means you’ll need cleaning more frequently. Wood should be seasoned for at least six months, ideally a year, and have a moisture content below 20%. You can grab a moisture meter for about twenty bucks, and it’ll pay for itself by preventing creosote problems.

The Every-Time Checklist

Some things need attention every single time you use your fireplace. Before each fire, check that the damper’s open. Remove ashes regularly, but leave about an inch of ash at the bottom of your firebox, it actually helps insulate and makes for better fires.

Never let ashes build up more than a few inches. And here’s something that surprises people: ashes can stay hot enough to start a fire for up to four days. Always put them in a metal container with a lid, and keep that container outside away from your house or deck.

What About Gas Fireplaces?

Gas units still need annual checkups. The venting system needs to stay clear, and the glass needs cleaning more often than you’d think. That white film that develops on the glass? It’s mineral deposits from combustion, and while it won’t hurt anything, it definitely kills the ambiance.

Gas logs should be inspected for proper positioning. If they shift, they can create dangerous carbon monoxide situations. Your pilot assembly and thermopile should be checked annually too. These components wear out, and it’s better to replace them on your schedule than when you’re expecting guests for the holidays.

Keep Records

Write down when you have inspections and cleanings done. Take photos if damage is found. This helps you track patterns and makes insurance claims way easier if you ever need to file one.

A well-maintained chimney should last 50 to 100 years, but that only happens if you’re staying on top of things. Neglect it, and you’re looking at major repairs or even a complete rebuild way sooner than necessary.
