Why Baltimore homes get repiped
67% of homes in Baltimore's covered ZIP codes were built before 1960 (67%, above the Maryland figure of 27%). That ranks 2nd highest of the 34 Maryland cities we profile. Homes of that age were plumbed with galvanized steel, which rusts from the inside until pressure drops and the water runs brown.
40% of the housing predates 1940. Many of those homes have had partial repairs over the decades, so it's common to find copper or PEX spliced into old galvanized runs, and those joints are where leaks start.
In Maryland: Older rowhouses in Baltimore and older suburbs have cast iron drains, galvanized lines and lead service lines.
Permits
A repipe normally needs a permit and inspection from your city or county, and the written quote should say whether wall patching is included.
