Chimney care in the 302 area
Around Wilmington, Newark and Dover, chimneys see both humid summers and freezing winters. Summer humidity can make a fireplace smell of creosote, and winter freeze-thaw cycles open up crowns and mortar joints. Chimney swifts nest in many open flues from spring to fall, so book cap installs and sweeps for after they leave.
