Why La Mirada homes get repiped
52% of homes in La Mirada's covered ZIP codes were built before 1960 (52%, above the California figure of 27%). That ranks 8th highest of the 151 California 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.
Only 1% predates 1940, so most older homes here are postwar houses from the 1940s and 50s, typically one main run of galvanized pipe with branches to each fixture.
In California: Seismic rules require water heaters to be strapped, and older homes often still have galvanized supply lines and cast iron or clay sewers.
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.
