Why Seattle homes get repiped
38% of homes in Seattle's covered ZIP codes were built before 1960 (38%, above the Washington figure of 21%). That ranks 2nd highest of the 27 Washington 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.
20% 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 Washington: Western Washington water is generally soft, and wet winters make drainage and crawl-space moisture common concerns.
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.
