Leak Detection — Find It Before It Finds You

Not all leaks announce themselves with a dramatic burst. Many of the most destructive water leaks hide behind walls, under floors, or beneath concrete slabs — silently causing structural damage, mold growth, and thousands of dollars in water waste. By the time you see visible signs, the damage may already be extensive.

Got Plumbing USA connects you with licensed leak detection specialists who use advanced technology — acoustic listening devices, thermal imaging, pressure testing, and tracer gas — to locate hidden leaks with pinpoint accuracy, minimizing the destruction needed to access and repair them.

Signs of a Hidden Leak

• Unexplained increase in water bills — often the first indicator
• Sound of running water when all fixtures are off
• Warm spots on floors (may indicate hot water slab leak)
• Mold or mildew smell without a visible source
• Discoloration or bubbling on walls, ceilings, or flooring
• Cracks in foundation from water erosion underneath
• Water meter spinning when no water is being used

How Professional Leak Detection Works

1. Meter test. Your plumber checks whether the water meter indicates a leak by shutting off all fixtures and monitoring movement.
2. Pressure test. The water system is pressurized to identify whether the leak is in the supply lines, drain lines, or slab.
3. Electronic detection. Specialized equipment — acoustic sensors, thermal cameras, and electromagnetic locators — pinpoints the leak location without unnecessary demolition.
4. Repair plan. Once located, the plumber provides repair options and upfront pricing before any work begins.

Leak Detection Cost

Professional leak detection typically costs $150–$600 depending on the complexity and equipment required. This is usually a flat fee that covers the detection service. The repair itself is quoted separately based on the leak location and type. Slab leak repairs can range from $500–$4,000+. The detection cost is a small investment compared to the water damage an undetected leak can cause.
