This week, we’re seeing a surge in Coatesville homeowners with 19th-century brick chimneys asking if summer is too early for a sweep. The answer isn’t about the calendar—it’s about the creosote in your flue and the masonry repairs your older home might need.
Myth: "A summer sweep is just for air conditioning—my fireplace isn’t even in use."
Coatesville’s older brick chimneys trap moisture from spring rains, and that dampness mixes with creosote to corrode liners and loosen mortar. Waiting until fall to schedule a Chimney Sweep in Coatesville often means missing the dry window needed to inspect and repair cracked flue tiles before winter. We’ve seen Coatesville homes with 1880s brickwork where a summer inspection revealed a liner crack that would have let carbon monoxide into the attic by December.

Our summer crews in Coatesville, Downingtown, and Exton are prioritizing homes built before 1950 because their masonry and liners age differently than newer builds.
