Cost to Repipe a House in Pennsylvania: $4,200–$7,700
In Pennsylvania, a PEX repipe of a house with 2 full baths and 11 fixtures costs an estimated $4,200–$7,700, and copper runs $8,600–$12,600. The estimate is based on national published prices scaled by plumber wages in Pennsylvania, 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 Pennsylvania that publish a repipe price, so the Pennsylvania figures are national prices scaled by the state's mean plumber wage.

Age of Pennsylvania's housing
Half of the housing units in Pennsylvania were built before 1966, by the Census Bureau's ACS 2024 1-year count. 44% 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.
