Under your floor
Finding it without guessing
Water under a slab spreads along the pipe, through the sand and out through cracks, so the wet spot is rarely above the break. Locating it takes several kinds of evidence that agree with each other.
- 1ListenSensitive microphones hear the hiss of pressurized water escaping through the concrete.
- 2Look for heatA thermal camera shows warm water from a hot line spreading under the floor.
- 3Trace the pipeLocating equipment follows the line so a sound or a warm patch can be matched to a real pipe.
- 4Pressure testIsolating each run shows which one is losing pressure, and which are healthy.
You can also take the meter test yourself first, before anyone visits.
What we do
Six ways to fix or protect the line

Five signs worth acting on
- The meter keeps moving with every fixture and appliance off.
- A warm or hot patch on tile or wood that stays warm at night.
- The sound of water running under the floor when the house is quiet.
- A bill that jumped without a change in how you use water.
- Damp flooring or a musty smell that keeps coming back.
None of these proves a leak on its own, and some Mesa look-alikes, such as irrigation, evaporative coolers and pool fill valves, can imitate every one of them. That is why we start with a simple check, not a sales pitch.

Choosing the fix
Four repair routes, side by side
The right one depends on how many leaks there are, what the pipe looks like and what is above it. A good quote shows more than one.
| Route | Best when | Trade-off |
|---|---|---|
| Spot repair | One leak, healthy pipe, reachable floor | Opens the slab at the leak |
| Rerouting | The leak is under tile, stone or a built-in | Wall and attic work; old pipe stays capped |
| Epoxy lining | Pipe is worn but still sound and accessible | Not suited to badly damaged pipe |
| Whole or partial repipe | Repeated leaks or pipe worn along its length | The largest job and cost |

Water running right now?
Do these three things before you dial, then call. They take about two minutes.
- Close the main shutoff.Usually at the front of the house near a hose bib, or in the garage.
- Stay clear of electricity.No wading near outlets or the panel. Gas smell or sparking means leaving and calling 911.
- Photograph the water and the meter.Useful later for any insurance claim.
What the emergency visit is for
The first goal is to stop the damage, not to start a large job at midnight. Typically that means confirming the water is off in the right place, making the area safe and working out whether the leak is under the slab, in a wall or at a fixture. The permanent repair is planned once the leak is located and you have seen the options in writing.

Questions
Before you call
What exactly is a slab leak?
It is a leak in a water supply line that runs in or beneath the concrete slab your house sits on. Because the pipe is buried, the first clue is usually indirect: a bill that jumped, a warm patch of floor or the sound of water with every tap off.
Will you have to break my floor?
Not always. Detection uses sound, heat, pipe tracing and pressure tests, none of which touch the floor. The repair may open a small section of slab, or it may avoid the slab entirely by rerouting the line, tunneling in from outside or lining the pipe. Each page on this site explains when each approach fits.
Is the emergency line really answered at night?
Yes. The emergency number, (480) 907-0504, is answered 24 hours a day, every day. Routine, non-urgent visits are scheduled separately, so a late-night call is for water that cannot wait.
How do I know it is the slab and not a leaking faucet or sprinkler?
Start with the meter test. If the meter moves with everything off and closing the main valve at the house stops it, the leak is inside the house. Irrigation, a pool fill valve or an evaporative cooler can imitate the same symptoms, so our guide to the signs walks through each one.
Does homeowner insurance cover a slab leak?
It depends on the policy. Many cover resulting water damage and sometimes the cost of reaching the pipe, but often not the repair of the pipe itself. We explain what to document and what to ask your insurer in our Arizona claims guide.
Which parts of Mesa do you serve?
Nineteen ZIP codes, from downtown and Dobson Ranch to Las Sendas, Eastmark and the east side. Our office is at 6810 E Mallory St in 85207. Check the service areas page or give us your address when you call.
