A second or third slab leak is a meaningfully different situation than a first one — and usually points to a systemic, not isolated, issue.
Copper pipe corrosion tends to progress gradually throughout a system, meaning if one section has failed, other sections of similar age are often not far behind.
A pattern of multiple leaks over a relatively short time span is one of the clearest signals that a reroute or whole-house repipe may be the more cost-effective long-term choice, rather than continuing with spot repairs.
We look at the age, material, and condition of the whole system — not just the most recent leak — before recommending a path forward.
There's no universal number, but two or more leaks within a few years is a common point where homeowners start seriously considering a repipe.
New PEX piping significantly reduces the risk profile compared to aging copper, though no plumbing system is entirely leak-proof forever.
Let's get you a real answer, not more guessing.
