Leak Detection in Santa Ana, CA

Professional leak detection costs $150–$500 depending on the method and location. Slab leak detection using acoustic equipment runs $150–$400. Thermal imaging adds $200–$400 for hard-to-locate leaks. The cost is almost always justified — undetected water leaks cause $5,000–$50,000 in structural damage.

Licensed plumbers use acoustic listening devices to hear water movement in pipes behind walls, thermal cameras to detect temperature differences caused by water, and pressure testing to isolate which section of the system is leaking — all without opening walls unnecessarily.

Common signs include: unexplained increases in your water bill, the sound of running water when nothing is on, warm spots on floors (slab leak), mold or mildew smell without visible moisture, cracks in foundation, and low water pressure throughout the home.

A standard leak detection appointment takes 1–3 hours depending on the suspected location and access. Slab leaks can take longer to pinpoint precisely. Most plumbers provide a written report with the leak location after the inspection.
