Why Somerville homes get repiped
69% of homes in Somerville's covered ZIP codes were built before 1960 (69%, above the Massachusetts figure of 47%). That ranks 2nd highest of the 37 Massachusetts 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.
60% 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 Massachusetts: Water is generally soft and can be corrosive, which shows up as pinhole leaks in copper and blue-green stains.
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.
