Baltimore is one of America’s oldest cities, and its plumbing infrastructure reflects that history in neighborhoods like Federal Hill, Fells Point, and Charles Village. Row homes built in the late 19th and early 20th centuries often retain original cast-iron drain systems, galvanized supply lines, and in older properties, lead service lines that the city is working to replace. Maryland requires plumbers to hold a state master or journeyman plumbing license, and Baltimore City has its own permit requirements. Winters in Baltimore can be harsh, with temperatures dropping well below freezing and increasing the risk of burst pipes, especially in older brick row homes with limited pipe insulation. The city’s aging combined sewer system can also lead to basement flooding during major storm events. Hard water from the Baltimore City water supply contributes to mineral buildup in water heaters and appliances. Common plumbing services in Baltimore include whole-house repiping, water heater replacement, sewer line inspection, drain cleaning, and emergency plumbing repair.
