Overview

Not every leak announces itself. Some hide inside walls, above ceilings, under the slab, or out in the yard, quietly wasting water and damaging your home long before you see a drip. A climbing water bill, a musty smell, or a warm spot on the floor may be the only clue that water is escaping somewhere you cannot see.

Our technicians locate hidden leaks with electronic amplification, acoustic listening, and pressure testing, so we find the source precisely instead of opening walls to look. Once we know exactly where and what the leak is, we give you an upfront, flat-rate quote and can repair it on the spot in most cases.

How it works

Our Water Leak Detection Process

  1. 1

    We start with your symptoms and a water meter check to confirm water is escaping somewhere in the system.

  2. 2

    We use electronic leak detection, acoustic listening, and pressure testing to narrow the leak to a precise location.

  3. 3

    We identify whether it is a supply line, drain, slab, or fixture leak and show you exactly what we found.

  4. 4

    We give you an upfront, flat-rate quote to repair the specific leak, with no exploratory demolition.

  5. 5

    In most cases we complete the repair the same visit and verify the leak is fully resolved.

FAQ

Water Leak Detection questions

Answers to what homeowners ask most. Still unsure? Call (562) 269-4747, we're happy to help.

How do you detect a leak without tearing up walls?

We use electronic leak detection and acoustic listening equipment that hear and amplify the sound of escaping water, along with pressure testing to isolate the affected line. This pinpoints the leak's location before we open anything, so any access is small and targeted rather than exploratory.

How can I tell if I have a hidden water leak?

Watch for a rising water bill, the sound of running water when everything is off, damp or discolored spots, a musty smell, or low pressure. A simple test: check your water meter, then wait an hour without using any water. If it moved, water is escaping somewhere.

Can a small leak really cause a lot of damage?

Yes. A slow, hidden leak can rot framing, ruin drywall and flooring, feed mold, and waste thousands of gallons over time, all before you notice it. Catching and repairing it early is far cheaper than repairing the water damage it causes, which is why fast detection matters.

Do you repair the leak once you find it?

In most cases, yes. Once we pinpoint the leak and identify its type, we give you an upfront quote and can typically repair it during the same visit. For a complex issue like an extensive slab leak, we lay out your repair options clearly before proceeding.

How much does leak detection cost?

It depends on the complexity of the search and the equipment needed. We provide upfront, flat-rate pricing so you know the cost before we begin. Locating a leak precisely almost always saves money versus opening walls and floors to search blindly.

How accurate is electronic leak detection?

Very accurate in trained hands. Acoustic and electronic tools let us localize most hidden leaks to a small area, which is what keeps repairs minimally invasive. If a leak is especially tricky, we combine methods, listening, pressure testing, and meter checks, to confirm the source before we open anything.
