How Much Does a Whole-House Repipe Actually Cost in 2026? (PEX vs Copper, From My Quote Scratchpad)
I keep a Notes app page called REPIPE??
It’s mostly numbers, little warnings to myself, and the occasional: “do NOT let anyone open the wall and then go ‘oh btw…’”
A whole-house repipe is not a cute little “replace a pipe.”
It’s a relationship with drywall.
It’s also a project that can look predictable from far away (“just run new lines”) and then turn into a million micro-decisions the minute somebody is actually in your crawlspace.
