Centreville’s October Chimney Sweep: 3 Things You’re Probably Missing
Most Centreville homeowners wait until December to sweep their chimneys, but by then, creosote (the flammable gunk from smoke) has already hardened into a brick-like layer. Here’s what a pro checks in October that DIYers skip: 1. Flue blockages: Centreville’s older homes (think near the historic downtown) often have flues with sharp turns.

Our crew covers these areas anchor with mobile units.
