Major Leak Detection & Repair in Addison
High water bill or hidden leak in Addison, TX? Acoustic + thermal detection locates it without demolition. Same-day service. Call (831) 290-4327.
Major leak detection in Addison finds hidden pipe leaks — inside walls, above ceilings, or under the slab — without random demolition. Belt Line Plumbing uses acoustic listening, thermal imaging, moisture meters, and tracer gas so the only hole in your wall is the one right next to the leak. Same-day location for high-water-bill and mystery-leak calls.
If your water bill doubled and no fixture obviously leaks, you have a hidden leak — usually inside a wall, above a ceiling, or under the slab. Belt Line Plumbing finds it without gambling on where to cut drywall. We use acoustic listening equipment, thermal imaging, moisture meters, and tracer gas so the only hole in your wall is the one right next to the leak.
Signs of a hidden leak
- Water bill spikes with no change in usage
- Meter dial moves when every fixture in the house is off
- A warm patch on the slab or floor (hot-water slab leak)
- Mysterious mildew smell, or a wall / ceiling stain that grows
- Sound of running water in the wall
- Foundation cracking or drywall cracking on the same wall as a plumbing chase
What's included with our major leak detection & repair
Every major leak detection & repair job with Belt Line Plumbing includes the deliverables below — quoted flat, in writing, before we start.
How we find leaks without demo
- 1Isolate to hot / cold / drainWe shut the water heater and re-check the meter. If the leak stops, it is a hot-water line. If it does not, it is a cold. We isolate before we start listening.
- 2Acoustic + thermalContact microphones pick up the hiss of pressurized water escaping into wall cavity or slab. Thermal cameras find hot-water leaks by the heat signature above the pipe.
- 3Trace gas when neededFor stubborn leaks, a helium/hydrogen tracer gas is charged into the line and sniffed at the surface — extremely precise.
- 4Cut small, fix onceA clean 6-inch access panel over the leak, not a demo pit. Repair, pressure test, close.
What drives the price
Every job we do is flat-quoted before we start — no hourly meter. The factors below determine what your specific number will be:
- Detection method (acoustic + thermal vs. adding trace gas)
- Access complexity (accessible wall vs. slab vs. two-story ceiling)
- Repair scope after location
