Emergency Leak Detection services

Cost depends on leak type (water vs. gas), property size, and whether acoustic, thermal, or tracer gas detection methods are required. National cost ranges from $150–$700 depending on scope and location. A verified plumber provides a written estimate covering price, scope, and permit requirements before any work begins — no obligation.

Three primary tools: (1) Acoustic listening devices — amplify the frequency of pressurized water escaping a pipe; distinguish pipe-leak signatures from ambient plumbing noise. (2) Thermal imaging camera — detects temperature differentials on walls, floors, and ceilings caused by warm-water leaks. (3) Pressure decay testing — isolates supply system sections and measures pressure drop over time to confirm a leak and estimate its location before any wall or floor investigation. Ground-penetrating radar is used for underslab cold-water leaks that don’t produce a thermal signature.

Run a meter test: locate your water meter, shut off all fixtures and appliances that use water, and observe the meter indicator. If the dial or digital flow display moves with everything off, water is moving through the system. Note whether the movement is fast (major leak) or slow (small drip). Also check whether your gas bill has spiked alongside your water bill — both spiking together usually means a hot-water-side leak. This test takes under five minutes and gives the plumber useful diagnostic information before arriving.

Not during detection. Acoustic and thermal methods locate the leak non-invasively in the large majority of cases. Repair is a separate decision and may or may not require wall or slab access depending on the leak location. The detection service fee ($150–$700) is billed separately from repair; some plumbers credit it against repair cost if you hire them for both. Clarify this during the estimate call.
