Leak Detection and Repair on Oahu

Leak repair is part diagnostics and part technique. Sometimes the source of a water problem is easy to find; other times it takes a trained plumber’s sleuthing. We find the leak, show you what we found, and fix it.

Signs you may have a leak

  • Low water pressure
  • Dampness in lower cabinets
  • A musty odor
  • A ceiling that’s stained or bubbling
  • Wet patches with no obvious cause
  • A water bill that’s higher than usual

A variety of water-related issues can crop up, especially in older homes. If you’re seeing any of these, call before the damage spreads.

Slab leaks

When a water or drain line runs under a concrete slab, a leak can show up far from where it starts: warm or damp spots on the floor, cracked flooring, or water appearing where it shouldn’t. The first job is to find exactly where the line is failing, so only what’s necessary gets opened up.

From there we’ll walk you through the options: repairing the damaged section, rerouting the line, or, for sewer and drain lines under the slab, trenchless pipe lining where the pipe allows, which can avoid tearing up floors. Some jobs do need the slab opened; we’ve done that work too, and we’ll tell you honestly which approach fits.

“I’ve used Pueo many times, most recently for a very major project involving replacing the sewer drainage pipes in our concrete slab and in our yard out to the sidewalk… Josh and Jessica, the owners, were great from the get-go. I couldn’t be more pleased with the end result.”

Leak detection questions

How do I know if I have a hidden leak?

Low water pressure, dampness in lower cabinets, a musty odor, a stained or bubbling ceiling, wet patches with no obvious cause, or a higher-than-usual water bill can all be signs. Call us and we’ll track it down.

Can you find a leak under a concrete slab?

Yes. We locate the failing section first, then explain the repair options, including rerouting the line or, for sewer and drain lines, trenchless lining where the pipe allows.

Yes. We stop the leak and replace damaged pipe. If you’re dealing with a major leak or loss of water, contact us right away and we’ll do our best to respond quickly.

Do you give estimates before starting work?

Yes. Whenever possible, we’ll explain the issue, walk through your options, and provide clear pricing before work begins.
