Some leaks you can see. Others show up as a high water bill, a warm floor or a stain that keeps coming back.

Dan picks up when he can and calls back the same day. Tell him what it's doing and you'll usually get a rough answer on the spot.

The job

How it goes

We start at the meter. If it turns with everything off, the leak is on the supply side. Then we isolate hot from cold, house from irrigation and branch from branch with gauges. Under a slab, the leak-locating specialist we bring in listens through the concrete and marks the leak, and any post-tensioned cables, before anyone cuts.

Around here it's usually pinholes in fifty-year-old copper, a slab leak, a failed shower pan leaking into the wall below, or a toilet seal. Irrigation shares the meter too, and it's often the answer when the bill jumps in summer.

If we can reach the pipe, we usually fix it that visit. Under concrete or behind tile, you get a written bid before anything's opened.

Call if

What you notice, and what it usually is

01

The water bill jumped for no reason

A supply leak. A ten-minute meter test narrows it down.

02

The meter turns with everything off

A leak somewhere between the meter and a fixture.

03

A warm spot on the floor

A hot line leaking under the slab.

04

A ceiling stain under a bathroom

A shower pan, toilet seal or drain joint. We find which before opening the ceiling.

05

Water running when nothing is on

A leak in a wall or under the floor.

Tell us what it’s doing and we can usually narrow it down on the phone.

Common questions

Things people ask about leak detection & repair

Do you have to open walls or floors to find it?

Not to find it. The meter and gauges do that, and under a slab the specialist marks the spot. The repair may need one opening, marked before anything's cut.

Could it be the irrigation?

Often. Sprinklers share the meter, and a broken lateral or a valve that won't close looks like a house leak on the bill. We check irrigation first.

Does insurance cover this?

Policies vary. Most cover sudden damage and the work to reach the leak. The pipe itself usually isn't covered. We give you photos for the claim.

How fast should I act?

Soon. A supply leak runs day and night. Shut off the main when you're out, and call us.
