Why Frederick homes need these repairs
Frederick is Maryland's second-largest city, with a historic downtown of 18th- and 19th-century brick rowhouses around Carroll Creek and fast-growing subdivisions to the east and north. The city treats water from several creeks and rivers rather than wells. Old pipes in the historic district, hard winters, basements in rolling terrain and new-build plumbing settling in subdivisions drive most of the frozen pipe, drain, sump and water heater calls here.
