Slab Leaks

Slab Leak Detection in Chandler, AZ

Most Arizona homes are built on a concrete slab, with water lines running beneath or through it. When one of those lines leaks, you can't see it — but there are signs. We find the leak before any flooring is opened.

About slab leak detection in Chandler

A slab leak is a leak in a water line that runs below or through the concrete foundation. Because the line is buried in or under concrete, the first clues are usually indirect: a bill that climbs for no reason, a warm patch on the floor, or the sound of water running when everything is off.

Slab-on-grade construction is common across the Phoenix area, which is why slab leaks are one of the most frequent hidden leaks we're asked about in Chandler. Our job is to confirm the leak is in the slab, narrow down where it is, and explain your options before anyone cuts into a floor.

Signs you may need it

  • Water bill creeping upNo change in habits, but the bill keeps climbing.
  • Meter moves with everything offCheck with all fixtures and appliances shut down.
  • Warm spots on the floorCan indicate a hot-water line leaking beneath the slab.
  • Sound of running waterAudible in quiet rooms when nothing is in use.
  • Damp carpet or baseboardsMoisture along walls with no other source.
  • Drop in water pressureNot explained by anything else in the system.

How we investigate

Tell us what you've noticed

Water bill changes, damp spots, sounds, pressure drops, warm floors — the history points us to where to look first.

We check the property

The meter, fixtures, accessible plumbing and any affected areas are checked methodically, from most likely source outward.

We narrow down the location

Findings are used to pin the leak to a specific area — a fixture, a wall, a section of slab or a stretch of buried line.

You get a clear explanation

We explain what we found and your repair options before any work begins, so there are no surprises.

The Arizona factor

Because Phoenix-area water is typically hard, mineral buildup can contribute to wear in older copper plumbing over the years, and shifting desert soils can stress lines beneath a slab. Neither is a guarantee of a leak — but both are reasons not to ignore the early signs.

Frequently asked questions

What causes a slab leak?

Common causes include pipe age and corrosion, joint failures, abrasion where a line contacts concrete or soil, and movement of the slab or the soil beneath it.

Will you have to break my floor?

The point of leak detection is to narrow down the location first, so any opening is limited to where it's needed. Repair options are explained before work begins.

How is a slab leak different from a pipe leak?

A pipe leak can occur anywhere in the plumbing, including exposed piping. A slab leak is specifically in a line below or within the concrete. See pipe leak detection for the rest of the system.
