    Whole-Home Repiping in McAllen, TX

    Posted prices from $7,663.50 to $15,764.50, installed, with no sales visit.

    Full water line replacement, installed, from $7,663.50, priced before the crew shows up, not after the drywall is open.

    If you've called us out for the third pinhole leak this year, or your water pressure has quietly dropped room by room, the pipe itself is usually the problem, not any one fitting. A whole-home repipe replaces the supply lines from the meter or main to every fixture, so you stop patching the same aging system one leak at a time.

    How to Know a Repipe Makes Sense

    A repipe usually pencils out once a home has had two or more slab or wall leaks in a short span, still has original galvanized steel supply lines, or was built during the years polybutylene piping was common. Galvanized pipe corrodes from the inside as McAllen's hard water deposits calcium and mineral scale along the interior wall, which is why older homes lose pressure gradually even with no visible leak. By the time a homeowner notices low flow at the shower head, the pipe interior may already be down to a fraction of its original diameter.

    Repeat pinhole leaks are the other clear signal. A single pinhole is a spot repair. Three or four over a couple of years, especially in different rooms, usually means the whole run of pipe is reaching the end of its service life at the same time, and a targeted fix just moves the next leak a few months down the line.

    PEX Through Walls and Attic vs. Copper

    Most repipes in the Valley today run PEX tubing through the attic and down through interior walls to each fixture, which lets us route lines with fewer joints and less demolition than rigid pipe requires. PEX also doesn't corrode the way galvanized steel does and tolerates our hard water better over the long run, since there's no metal interior surface for scale to build up on.

    Copper is still available for homeowners who want it, particularly for exposed runs or when matching existing copper elsewhere in the house. Copper costs more and takes longer to run through finished walls, but some homeowners prefer it for exterior hose bibb lines or commercial-adjacent applications. We'll walk you through both before anything's decided, with each option's price posted up front.

    What the Job Week Actually Looks Like

    Repiping a typical McAllen home takes a few days from start to water-tight finish, depending on square footage and whether the home is on a slab or has a crawlspace. The first day or two focuses on running new lines and making the connections at each fixture; water is shut off in sections rather than to the whole house whenever the layout allows it. Once the new lines are pressure-tested, we cut back over to the new system and cap the old galvanized or polybutylene lines.

    Because most of the routing happens in the attic and through top plates rather than tunneling through the slab, access holes are typically limited to small sections of wall or ceiling near each fixture, not full-room demolition. We coordinate the drywall patching and texture matching as part of the job so you're not left managing a separate contractor after we're done.

    Permitting, Warranty, and What's Included

    Whole-home repiping requires a permit in most Rio Grande Valley municipalities, and we pull it and schedule the inspection as part of the posted price, not as an add-on you have to track down yourself. Every repipe comes with a written workmanship warranty on the new piping and connections.

    Because the price is posted before work starts, you know the full installed cost, from $7,663.50, before we ever cut into a wall. There's no in-home sales visit and no revised number once the job is underway; the scope is confirmed on-site against the posted options and locked in before approval.
