    What a Re-Route Actually Is

    Once slab leak detection confirms where the failed line is, a re-route means we cap and abandon that damaged section under the concrete entirely rather than trying to access and repair it in place. We then run new copper or PEX piping through the attic, down through interior walls, and back to the fixture it's feeding — bypassing the slab completely.

    This isn't a shortcut; for most residential slab leaks it's the more durable fix, because the new line never has to fight expansive soil movement the way the old under-slab pipe did. It restores full water pressure and flow without depending on decades-old piping buried in concrete.

    Re-Route vs. Breaking the Slab vs. Full Repipe

    Cutting into the slab to access and patch the exact failure point is sometimes the right call for a single, isolated leak in an easy-to-reach spot, but it means demolition, a wet-set patch, and flooring repair over a hole in your foundation. For most homes, a re-route avoids that entirely while fixing the same underlying problem.

    A full repipe — replacing every water line in the house — is worth discussing separately if you're on older galvanized piping or have already had more than one slab leak, since McAllen's hard water and clay soil tend to age an entire plumbing system at roughly the same rate. But for a single confirmed leak, a targeted re-route is usually the most cost-effective, least disruptive option.

    Timeline and What Happens to Your Walls

    Most re-routes are completed in one to two days depending on the distance the new line has to travel and how many walls it passes through. We cut clean, minimal access openings in drywall to route the new pipe, then cap and seal each one.

    Wall and ceiling patching after a re-route is generally limited to a handful of small openings rather than an entire section of flooring, which keeps your overall repair cost and downtime lower than a slab excavation. We'll walk you through exactly which walls will need access before we start so there are no surprises.

    Insurance Paperwork and Why Re-Routes Fit Post-Tension Slabs

    If you're filing a claim for water damage from the leak, we provide documentation of the failure, the repair method, and photos throughout the job that most insurance adjusters ask for. Keep your detection report alongside this paperwork since together they tell the full story of the claim.

    Post-tension slabs, common across newer McAllen and Edinburg subdivisions, contain steel cables under tension that make cutting into the concrete riskier and more specialized than in a standard slab-on-grade foundation. Re-routing avoids that risk altogether, which is a big reason it's become the standard approach for slab leaks on post-tension construction throughout the Valley.
