Signs You May Have a Slab Leak

Slab leaks can quietly cause thousands of dollars in damage if left untreated. Call GPS Plumbing if you notice:

  • Unusually high water bills
  • Warm or damp spots on flooring
  • The sound of water running when no fixtures are on
  • Cracks in your foundation or flooring
  • Mold or mildew near the baseboards
  • Low water pressure
  • A water meter that keeps spinning

Even small slab leaks can lead to serious damage beneath your home’s foundation. Early detection is key!

We’ll explain what we find, walk you through all your options, and never upsell. You get clear answers and straight pricing.

Slab Leak Repair Methods We Offer

Every home is different. We tailor repairs based on your plumbing layout, the leak’s severity, and your long-term needs.

  • Rerouting Water Lines: We bypass the leak entirely by rerouting new water lines through the attic or walls—often the best long-term solution.
  • Tunneling Under the Foundation: We dig tunnels under the slab to reach the leak, preserving your flooring. This is often preferred for major repairs or when multiple leaks are found.
  • Direct Access Repair: We open the slab at the leak location and repair the pipe. Best for isolated leaks.

During one recent slab leak repair, the team discovered that a pipe indentation had caused cavitation leading to internal turbulence, and the formation of a pinhole leak. To ensure a lasting fix, our plumber replaced the affected section and applied mill wrap pipe covering over the press fittings to protect them from corrosion and abrasion beneath the foundation.

Frequently Asked Questions

What causes slab leaks in North Texas?

Most are caused by shifting foundations, aging copper pipes, poor installation, or extreme temperature swings.

How serious is a slab leak?

Very. Even a small leak can erode the soil beneath your home and lead to foundation cracks, mold, and high water bills.

Does my insurance cover slab leak repair?

Every policy is different. Some cover access to the leak but not the plumbing repair itself. We’re happy to document the work and help you submit your claim.

How long does slab leak repair take?

Detection usually takes 1–2 hours. Repairs can range from a few hours to several days depending on whether we tunnel, reroute, or do direct access.

Can I ignore a small slab leak?

We strongly advise against it. Slab leaks rarely fix themselves—and delaying repair often causes more expensive damage down the line.
