Slab Leak & Water Leak Detection in Pasadena

Many Pasadena homes sit on concrete slabs with copper supply lines running underneath. Decades of Pasadena's hard water and soil movement wear pinholes into that copper, and the leak hides under the slab — quietly soaking your foundation, spiking your water bill, and warming a patch of floor before you ever see a drop. Caught early, a slab leak is a manageable repair. Ignored, it becomes foundation and mold damage.

We locate hidden leaks precisely using acoustic listening equipment, pressure testing, and thermal imaging — so we open up only the spot that needs it, instead of guessing and cutting open walls or floors.

Signs of a Hidden or Slab Leak

  • A warm spot on the floor (hot-water slab leak)
  • Water bill climbing for no clear reason
  • Sound of running water with everything shut off
  • Cracks in flooring or the foundation
  • Musty smell, mildew, or damp baseboards
  • Low water pressure throughout the house

Why Early Detection Pays Off

Catch Leaks Early

🎯

Pinpoint Accuracy

Acoustic and thermal tools find the exact leak location, so repairs are surgical — not a wall full of guess holes.

🏠

Protect Your Foundation

Slab leaks left alone undermine the foundation and breed mold. Early detection keeps a small repair from becoming a major one.

💵

Stop Wasted Water

A hidden leak can add hundreds to your bill. Finding and fixing it pays for itself fast.

🔧

Repair or Reroute

Depending on the pipe, we repair the spot or reroute the line — and for repeat-offender copper, we discuss repiping.

Common Questions

Slab Leak & Water Leak Detection in FAQ

What's a slab leak, exactly?
It's a leak in a water line running beneath your concrete foundation. Telltale signs are a warm spot on the floor, the sound of water with everything off, and a rising water bill. They're common in Pasadena's older slab homes.
Can you find a leak without breaking everything?
Yes. We use acoustic listening and thermal imaging to locate the leak precisely, then access only that spot — no tearing open walls and floors on a hunch.
Should I repair the leak or repipe?
One isolated pinhole can be spot-repaired. But if your copper has leaked more than once, the rest is usually close behind — at that point a partial or full repipe is the smarter long-term fix.
Is a small leak really urgent?
Yes. Even a slow hidden leak feeds mold and weakens your foundation over time, and it never gets cheaper to fix. The sooner we find it, the smaller the repair.
