Damascus homeowners ask us one question every fall: *‘Do I really need a chimney sweep before lighting my first fire?’* The answer isn’t just ‘yes’—it’s ‘now.’ With Oregon’s rainy season turning to fireplace season, a blocked or creosote-laden chimney isn’t just inefficient; it’s a silent carbon monoxide risk. Here’s what you need to know before your first burn—including why some Damascus homes need sweeps *twice* this year.
‘Should I Sweep My Chimney If It Looks Fine?’ (The Damascus-Specific Answer)
Your chimney might *look* fine from the outside, but Damascus’s damp climate hides a danger: creosote buildup accelerates in unventilated flues. Last winter, we found *three* Damascus homes with undetected creosote layers—one thick enough to trigger a smoldering fire during a single burn. The Chimney Safety Institute of America (CSIA) calls this ‘Stage 2 creosote,’ a tar-like substance that ignites at lower temps than wood. Check our Damascus service area to see if your home’s flue material (brick vs. metal) changes your risk. Pro tip: If your fireplace smokes *even when new logs burn hot*, that’s your first warning sign.

‘Is It Worth Sweeping Twice This Year? Damascus Homes with These 3 Traits Need Extra Care’
Damascus’s older homes (pre-1980s) and those with *wood-burning stoves* often need **two sweeps per season**—not because of laziness, but because of how creosote forms. Here’s the science: Wet, unseasoned wood (common in Oregon’s damp fall) creates *more* creosote than dry cordwood. Add a chimney that hasn’t been swept since last winter, and you’ve got a recipe for a **carbon monoxide buildup**—especially in tight-knit neighborhoods like Happy Valley or Boring, where older homes share similar flue designs. Our crew inspects for hidden risks like cracked liners or blocked caps, which are code violations in Clackamas County.
