Leak Detection & Repair

An undetected water leak can cause thousands of dollars in structural damage, promote mold growth, and drive up your water bill dramatically — all while staying completely invisible behind drywall or under a concrete slab. Thomas's Santa Monica Plumbing uses electronic acoustic listening devices and thermal imaging techniques to pinpoint leaks without unnecessary demolition. We'll map out exactly where the leak is before opening any wall or floor, minimizing repair scope and restoration costs.

Slab leaks are particularly common in Santa Monica and surrounding coastal communities, where older copper pipes are susceptible to corrosion from soil movement and electrolytic activity. Our slab leak detection process isolates the affected line, and depending on the leak's location and severity, we can offer spot repair, pipe rerouting through interior walls, or epoxy pipe lining as a less-invasive alternative. We walk you through every option clearly so you can make an informed decision.

Beyond slabs, we also detect and repair leaks in bathroom and kitchen supply lines, toilet fill valves, shower pan liners, irrigation backflow connections, and outdoor hose bibs. If your water meter is spinning when all fixtures are off, that's a strong signal you have an active leak — call us immediately and we'll dispatch a technician the same day.
