Cost to Repipe a House in Massachusetts: $5,000–$9,200
In Massachusetts, a PEX repipe of a house with 2 full baths and 11 fixtures costs an estimated $5,000–$9,200, and copper runs $10,100–$14,800. The estimate is based on national published prices scaled by plumber wages in Massachusetts, plus one local plumbing permit fee. A fixture is anything a supply line feeds: a toilet, sink, tub, shower, dishwasher, washing machine or hose bib.1,
This site found fewer than two plumbing companies in Massachusetts that publish a repipe price, so the Massachusetts figures are national prices scaled by the state's mean plumber wage.

The Board of State Examiners of Plumbers and Gas Fitters licenses plumbers in Massachusetts. There are two license levels, journeyman and master.

Plumbing code in Massachusetts

Age of Massachusetts's housing
Half of the housing units in Massachusetts were built before 1965, by the Census Bureau's ACS 2024 1-year count. 45% were built before 1960, when galvanized supply pipe was common. 18% were built from 1980 to 1999, the two Census decades that overlap the years polybutylene pipe was made. Age alone does not tell you what pipe a house has; a plumber or inspector can.
