A hidden leak can run for weeks before you notice it — and in Houston, where most homes sit on a concrete slab, the damage adds up fast. Houston Flow Plumbing specializes in locating leaks without tearing up your house first. Our Texas Master Plumbers use electronic acoustic equipment, thermal imaging, and pressure testing to pinpoint the exact spot of a leak, whether it's under the slab, behind a wall in Memorial, or out in the yard service line in Pearland. We've made slab leaks one of our specialties since 2010 because, frankly, Houston's soil guarantees plenty of them.
Watch for the warning signs: a water bill that jumps for no reason, the sound of running water when every fixture is off, warm or damp spots on the floor, a foundation that's suddenly cracking or heaving, or the smell of mildew you can't track down. A water meter that keeps creeping when nothing is on is the clearest tell of all. Catching these early is the difference between a targeted repair and a full mold remediation.
The reason slab leaks are so common here comes down to Houston's expansive clay soil. Our gumbo clay swells when it's wet and shrinks hard during dry spells, and that constant movement stresses the copper and galvanized lines buried in or under the slab until they crack or develop pinhole leaks. Flat grade and our flooding history only make moisture levels swing more. It's the same soil behavior that drives so much of the repiping and pipe repair work we do across the metro.
Once we've located the leak, we explain exactly what's going on and lay out your options in plain language with a flat-rate price before any repair begins. Sometimes a single spot repair is all you need. Other times, especially with aging copper that's leaking in multiple places, a section of repipe is the smarter long-term call, and we'll tell you honestly which one makes sense. If the leak is on the main sewer or drain side, we'll bring in sewer camera inspection to confirm the source before digging.
We run 24/7 with no overtime surcharge, carry BBB A+ accreditation and a 4.9-star rating from 2,030 reviews, and offer GreenSky financing for larger repairs. Don't let a hidden leak quietly wreck your foundation or your water bill — call (713) 555-0164 and we'll find it today, anywhere from Bellaire to Tomball.
