Leak Detection in San Diego

Water Where It Should Not Be, Found Fast

Find It Before It Finds You

We Find The Leak Before We Open Anything

Unexplained increases in your water bill, damp or moldy spots, and hissing sounds are all signs of a hidden leak. Left alone, a small leak causes damage you can't see until it's expensive.

Our technicians locate leaks with non-invasive methods first: thermal imaging cameras, acoustic listening equipment, and tracer gas. When a leak hides deeper, video inspection cameras find it before anyone opens a wall or a slab. That photo on the right is one of ours: an underground supply line located, opened, and repaired with new copper.

We Can Locate & Repair

Every Kind Of Leak, Found And Fixed

Slab Leak Detection

A warm spot on the floor or the sound of running water under concrete. We pinpoint slab leaks electronically and repair with minimal demolition, like our recent slab jobs in Carlsbad and Escondido.

Acoustic Detection

Sensitive listening equipment picks up the sound of water escaping a pressurized line, locating the leak without opening walls.

Thermal Imaging

Temperature differences reveal moisture inside walls and ceilings before there is visible damage.

Gas Leak Detection

A gas leak is an emergency. We locate and repair gas line leaks safely and to code. If you smell gas, leave the building first, then call.

Leak Repair & Repipe

Once found, we fix it: spot repairs, reroutes, or a whole-home repipe when old pipe has reached the end of its life.

Video Inspection

When the source is not obvious, an in-pipe camera shows exactly what is happening so the repair is accurate the first time.

Know The Signs

Signs You Have A Hidden Leak

A leak you cannot see is still costing you every day. These are the ways one usually announces itself.

The Bill Jumped

A water bill that climbs with no change in habits is the most common way a hidden leak shows up first.

The Meter Moves With Everything Off

Shut every fixture in the house, then watch the meter. If it is still moving, water is going somewhere it should not.

A Warm Spot On The Floor

A warm patch on a slab usually means the hot side of a line under the concrete is leaking beneath your feet.

Running Water You Cannot Find

Hearing water with nothing switched on means it is moving inside a wall, a ceiling or the slab.

Musty Smell Or Damp Drywall

Water behind drywall shows up as a smell before it shows up as a stain. Either way it has been going a while.

New Cracks In Concrete

Moving water washes out the ground under a slab or patio. Fresh cracks near a plumbing run are worth a look.

How We Find It

Electronic Detection Versus Opening Walls

Both find the leak in the end. The difference is how much of your house is open when we get there.

How It Works

What Happens When You Call

1

Initial Assessment

We inspect the property, check the meter, and review the visible evidence to narrow down where the leak lives.

2

Locate Without Demolition

Thermal imaging, acoustic listening, and tracer methods find the leak precisely, so we open one spot instead of five.

3

Repair And Verify

You get repair options with upfront prices. After the fix, we verify the line holds pressure and document the work.

Frequently Asked Questions

Your Leak Detection Questions, Answered

What are the common signs of a water leak?
Unusually high water bills, damp or moldy odors, wet spots on walls or floors, and the sound of running water when no taps are open.
Can leak detection find hidden leaks?
Yes. Thermal imaging, acoustic equipment, and tracer methods locate leaks in walls, under slabs, and in underground pipes without tearing things open to look.
How long does leak detection take?
It depends on the complexity of the leak, but most detections are completed within a few hours.
Can't I find the leak myself?
Some leaks are visible, but the damaging ones usually are not. Professional equipment locates hidden leaks accurately, which saves money on both the water bill and the repair.
Can leak detection help prevent future leaks?
Yes. Finding one leak often reveals the condition of the surrounding plumbing, and we'll tell you honestly whether a spot repair is enough or aging pipe needs attention.
