Phoenix Valley · two repair paths
Reroute versus spot repair after a slab leak
Once a line under the slab is found, the usual choice is to open the concrete at the leak or abandon that run and reroute through a wall, attic, or garage. Both are real jobs. This page explains the tradeoff so you can ask a better question. It does not choose, and it does not do the work.
What a spot repair is
The locator marks the leak. A crew opens a hole in the slab, repairs or replaces a short section, and patches concrete. Then someone restores floor covering. It is the smaller plumbing job when the rest of the line still looks sound and the finish is cheap to match.
It is a poor fit when the floor is rare stone, when there are multiple leaks, or when the remaining copper is the same age as the failure.
What a reroute is
A reroute leaves the bad line in the slab (usually capped) and runs a new line where it can be repaired later — attic, garage soffit, or walls. You pay more plumbing and less jackhammering in the living room.
It is a poor fit when there is no path that stays out of the slab, or when a single cheap opening would have finished the job.
Typical cost — ranges, not a menu
In this market a contained spot repair is often quoted from roughly $800 to $2,500+ depending on access and finish. A household reroute is often $1,500 to $5,000+ depending on how many fixtures move and how finished the walls are. Outliers exist in both directions.
Those figures are what owners typically hear, not a bid from this website. Provider pricing is still unknown here.
What this page will do
We can pass a request that says “found leak, need repair options” or “need a locate first.” We will not tell you that reroute is always smarter. A licensed local leak or plumbing firm may contact you. You can get a second opinion before anyone opens a floor.
