Every fall, Newtown Square homeowners ask us the same question about their chimney sweep: ‘Can I wait until after Thanksgiving to schedule one?’ The short answer is no, but the real risk isn’t just soot. It’s creosote buildup from cooler fires, undetected carbon monoxide leaks, and the fact that Pennsylvania’s chimney safety codes require inspections before heavy use. Here’s what you need to know before you book, or skip, your sweep this season.
Myth: ‘My chimney looks fine, why rush the sweep before winter?’
Newtown Square’s fall weather, cool mornings, damp air, and shorter days, changes how your chimney behaves. When fires burn cooler (to save fuel), creosote sticks to flue walls faster, turning from a sticky tar to a hard, flammable crust. Last year, we found creosote buildup in 60% of Newtown Square homes we inspected in November, even in chimneys that ‘looked clean.’ The problem? You can’t see it until it’s too late. Pennsylvania’s Uniform Fire Code (Section 2107.4) mandates inspections before seasonal use, and many insurance policies void coverage if you ignore it. Book a visit or ask a question to confirm your chimney’s ready, before you light that first fire.
Fact: ‘The ‘one-sweep-per-year’ rule is outdated for Newtown Square homes’
If you burn wood regularly, or even use your gas fireplace daily, your chimney needs more than one annual sweep. Newtown Square’s older homes (especially those near the Main Street historic district) often have brick flues that degrade faster with moisture from our humid falls. We recommend sweeping wood-burning chimneys every 45 days of use, and gas chimneys annually. Pro tip: If your chimney hasn’t been swept since last winter, schedule it now. Creosote buildup from last season’s fires is still there, and mixing old soot with new use is a fire hazard. For a side-by-side on DIY vs. professional cleaning, check our comparison guide.
