Leak Detection & Slab Leaks

Leak detection in Dallas & DFW — find hidden leaks before they cause major damage.

Unexplained water bills, warm spots on the floor, or musty smells can all point to hidden plumbing leaks. 448 Plumbing uses electronic leak detection, pressure testing, and camera inspections to locate leaks under slabs, in walls, and in hard-to-reach places.

Common signs of hidden leaks

  • Sudden, unexplained increase in water bills
  • Warm or damp spots on floors or carpets
  • Cracks in walls or foundation
  • Musty or moldy odors near baseboards
  • Sound of running water when fixtures are off

How we locate leaks

We combine pressure testing, electronic listening devices, and in-line cameras to narrow down leak locations. This allows us to recommend the least invasive, most effective repair strategy.

Repair options for slab leaks

Depending on where the leak is and how your home is plumbed, we may recommend spot repair, rerouting lines overhead, or partial repiping. We'll explain each option clearly with pricing and expected disruption.

Why fast leak detection matters

Left untreated, slab and wall leaks can lead to structural damage, mold growth, and expensive restoration work. Early detection helps limit these risks, saving you time, stress, and money.

If you suspect a leak but aren't sure, call us anyway. We'll help you decide whether a professional inspection is warranted based on your symptoms and home history.

Leak detection FAQ

Do I always have to tear up floors for a slab leak?

Not always. In many cases we can reroute lines through walls or ceilings instead of breaking large areas of concrete. We'll explain the pros and cons of each option once we locate the leak.

How accurate is electronic leak detection?

Modern leak detection tools are very sensitive and help narrow the search area significantly, but they are still part of a full diagnostic process. We combine tool readings with plumbing knowledge to pinpoint likely locations.

Can hidden leaks affect my home's foundation?

Yes. Long-term leaks under slabs can wash away soil, create voids, and stress the foundation. Addressing leaks early is one of the best ways to protect your home's structure.

Do you work with insurance companies?

We can provide documentation about the leak, location, and repairs so you have what you need if you choose to file a claim. Coverage varies by policy, so it's always best to check with your insurer.
