Wilmington’s climate and local fuels mean your chimney needs seasonal attention. Do these safe DIY checks now, then schedule a pro sweep every 1–2 years—or sooner if you spot trouble.
What Most Wilmington Homeowners Get Wrong About Chimney Frequency
Most folks think chimneys only need cleaning before winter. Wrong. Wilmington’s damp springs and summer storms leave soot and moisture that corrode flues year-round. The real rule: burn wood? Sweep every 1–2 years. Gas or oil? Every 2–3 years. Burn wet or resinous wood like pine? Cut that to 1 year. Skip this and you risk creosote buildup that can ignite—a real hazard in older Wilmington homes with narrow flues.
