This time of year, Mercer Island homeowners with older brick chimneys often notice a persistent campfire smell indoors—even when the fireplace hasn’t been lit. We’re answering this exact question to help you protect your home before winter sets in.
Why your Mercer Island brick chimney smells like a campfire in fall
If your older brick chimney on Mercer Island smells like a campfire this fall, it’s likely trapped creosote and moisture from summer use or seasonal humidity. Older masonry absorbs odors and holds onto soot, especially in homes near Lake Washington’s damp air. A professional inspection can identify if your liner or flue needs cleaning or repairs before winter. Don’t mask the smell with candles—address the source now to avoid costly damage or unsafe fireplace use.
What to do if your Mercer Island chimney smells like smoke when it’s cold out
A cold snap can make older brick chimneys on Mercer Island release trapped odors indoors. This happens when temperature drops force air downward through the flue, pushing lingering soot and moisture back into your home. If you notice this, schedule a chimney sweep and inspection before lighting your first fire. Ignoring it risks further brick deterioration or even carbon monoxide risks. A licensed sweep will also check your liner and mortar joints for cracks common in homes built before 1980.
