Why Hidden Leaks Can't Wait
A pinhole leak behind a wall can waste thousands of gallons a month and quietly rot framing, breed mold, and undermine your foundation long before you see a stain. In Arcadia, we find hidden leaks most often in three places: aging copper supply lines under concrete slabs, corroded galvanized pipes inside walls of mid-century homes, and failed fittings behind showers and tubs.
The old way of finding leaks meant cutting exploratory holes and hoping for the best. We do it differently — with professional diagnostic equipment that locates the leak to within inches, so the repair is surgical, fast, and far less expensive.
Our Leak Detection Technology
- Acoustic listening equipment — ultra-sensitive microphones hear pressurized water escaping through pinholes, even under concrete.
- Thermal imaging cameras — detect the temperature differences wet areas create behind walls, ceilings and floors.
- Moisture meters — map exactly how far water has spread so nothing gets missed.
- Pressure testing & isolation — we isolate sections of your plumbing to confirm which line is leaking before any repair.
- Sewer camera inspection — for suspected drain-line leaks under slabs or in yards.

Leak Detection FAQs
Watch for unexplained water bill spikes, running-water sounds with everything off, damp spots, musty odors, warm floor spots, or a water meter that moves when all fixtures are off. Any one of these deserves a professional check.
Professional leak detection starts with pinpointing the exact spot — which means a smaller repair job. The repair is handled separately. Call (626) 555-0147 to discuss your situation.
No. Acoustic sensors, thermal cameras and moisture meters locate leaks non-invasively. We only open the wall or floor at the exact leak location — usually a small, easily patched area.
A slab leak is a broken water line under your concrete foundation — common in Arcadia homes with in-slab copper lines. Left alone it erodes soil, cracks foundations and wastes enormous amounts of water. Early detection keeps the repair small and affordable.
