Pipe Repair in Maryland
A single leak in otherwise sound pipe gets a spot repair. When pipe has repeated leaks, is galvanized with low pressure, or is polybutylene (gray plastic, common 1978–1995), repiping the house is usually the lasting fix.

What drives pipe repair calls in Maryland
Old cast-iron stacks
When: Not weather-driven. What fails: Original cast-iron drain stacks in rowhouses corrode and leak. What to do: Have the stack inspected before remodeling a bathroom or basement.
Winter: Pipes in rowhouse rear additions and on exterior walls freeze during cold snaps.
Baltimore's rowhouses, many built before 1940, often have original cast-iron drain stacks and galvanized supply lines. Montgomery and Prince George's County suburbs are mostly post-war and newer, and Eastern Shore homes from Easton to Salisbury often have their own well and an on-site system near the bay.
