Slab Leak Detection in Phoenix, Find It Before It Finds You

To find a slab leak without tearing up your floor, we use electronic detection equipment. Once we've located the leak, you get the repair price to approve before any work starts.

Slab leak detection means finding a hidden water leak. We track it down with electronic equipment before anyone cuts into a floor, and you approve the repair price before we start. Watch for a warm spot on the floor, a water bill that jumped $80, or the sound of water running when everything is off.

The longer a slab leak runs, the more it costs to fix.

Brian McQuistion Plumbing & Drain uses electronic detection equipment to find slab leaks without tearing up your floor. We locate the leak first. Then we talk about the repair.

What Can Cause Slab Leaks in Phoenix

Some Phoenix-area soils swell when they get wet and shrink when they dry out. The desert climate means dry soil for months, then monsoon saturation, then back to dry. That constant movement can put stress on buried pipes. Combine that with Phoenix's hard water corroding pipes from the inside and you have two forces working against your plumbing at once.

Homes built before 2000 often have older copper pipe that's been taking that abuse for decades.

Signs You Might Have a Slab Leak

  • Hot spot on your floor (warm to the touch for no reason)
  • Sound of running water when nothing is on
  • Water bill spiked without a change in usage
  • Wet or damp flooring with no visible source
  • Mold or mildew smell near floor level
  • Cracks appearing in walls or flooring

How We Find It

We use electronic leak detection equipment to locate the leak without opening your floor. Once we know exactly where it is and how bad it is, we walk you through the repair options, including whole-house repiping if the system is broadly compromised.

Frequently Asked Questions

The cost starts with our $59 diagnostic. From there you get the full price for the repair. You approve it before any work begins.

No. The longer a slab leak runs, the more it costs to fix. A leak can also create the moisture that mold needs to grow. Call us as soon as you suspect one.

It depends on your policy. Homeowners policies generally cover damage from a sudden and accidental discharge from a plumbing system. Your insurance company can tell you how your policy applies to a slab leak.

It could be a slab leak. Other causes include a running toilet, a dripping outdoor hose bib, or an irrigation system leak. But a slab leak is worth ruling out, especially if you also hear running water when nothing is on. We can inspect it.

Possibly. Phoenix hard water drives slab leaks in homes built before 2000. A home built in 1985 is in that group. That doesn't mean you have a slab leak. If you've never had your home checked, it's worth a look.
