Hidden plumbing leaks can cause serious damage long before they’re visible. Watch for warning signs, such as unexplained spikes in your water bill or musty odors. You might also notice damp spots, warped flooring, peeling paint, or low water pressure throughout your home. In some cases, leaks can even create warm or cold areas on your floors or cracks in your foundation. If you notice any of these warning signs, give Roto-Rooter a call for quality leak repair in St. Louis.  

While you can spot visible drips or damp spots, most leaks are hidden inside walls, ceilings, or foundations, where DIY detection isn’t reliable. Home leak detectors can help identify moisture, but they can’t pinpoint the source. Roto-Rooter’s specialized tools and experience ensure accuracy and prevent incomplete repairs that can lead to leaks returning.

Many St. Louis neighborhoods have older homes with galvanized or cast-iron pipes that corrode over decades. In addition, Missouri’s clay soil expands and contracts with seasonal moisture, which stresses buried water lines and joints. Freezing winter temperatures also make pipes more prone to cracking and bursting.

Even a slow drip can cause major long-term damage. Water seeps into the flooring and drywall, promoting mold and rot that spread beyond the visible area. Left unchecked, a “minor” leak can weaken your structure, destroy insulation, and double your repair costs later. 

Most residential leak inspections take one to two hours, depending on the home’s plumbing layout and accessibility. Complex or multi-level properties may require additional time to test each zone. Once located, our team provides a complete explanation, repair options, and a transparent estimate on-site.

Our technicians use non-invasive leak-detection tools such as acoustic sensors, infrared cameras, and moisture meters. These devices pinpoint the exact location of a leak by detecting temperature changes, sound patterns, or humidity levels. That means we can identify and repair the source precisely, without unnecessary demolition or guesswork.

If you notice unexplained damp spots, warm areas on your floor, or a sudden spike in your water bill, you may have a leak beneath your slab or foundation. Other warning signs include low water pressure, the sound of running water when everything is turned off, cracks in the flooring, or musty odors near walls and baseboards. These leaks occur under the concrete foundation and are often caused by soil movement or aging pipes. Roto-Rooter professional leak repair in St. Louis can quickly confirm whether the problem is coming from your slab or another part of your plumbing system.

Turn off your home’s main water supply valve immediately to prevent further flooding or damage. Then, unplug electrical devices near wet areas and avoid walking on soaked flooring. Call Roto-Rooter right away for emergency service.

We use electronic locators and line tracing to find the damaged section precisely. Once marked, our team performs targeted excavation or uses trenchless methods to minimize disruption.
