Quick Answer
What is the most important seasonal chimney task?
Get a sweep and inspection once a year, in late summer or early fall, before you burn. Everything else — cap checks, leak checks, crown checks — flows from that annual visit.
Book your annual sweep and Level 1 inspection now. Clear creosote, confirm the cap is intact, and make sure the flue draws before the first cold night.
Watch for smoke pushing back into the room, a strong smell, or a cap clogged with ice — all signs to stop and call. Never burn on an unswept or unknown flue.
Check for winter damage: cracked crown, spalling brick, rust on the cap, and any staining or moisture near the chimney. Freeze-thaw is hard on masonry.
Off-season is when to handle relines, masonry, and cap or animal-guard installs — dry weather, open schedules, and no rush to get the fireplace working.
