Somerville is one of the densest cities we work in — triple-deckers and two-families packed across Winter Hill, East Somerville and around the squares, many still running galvanized supply lines and cast-iron drains. We handle leak repair, repiping, water heater and boiler replacement, gas fitting and drain clearing, pulled under the correct City of Somerville permits and done with respect for your building and neighbors.
