Slab Leaks: The Hidden Threat Beneath Your Home

When it comes to plumbing problems, few are more damaging—and more overlooked—than a slab leak. These leaks happen under your home’s concrete foundation, silently undermining your structure, raising your water bills, and feeding mold growth before you ever see a single drop.

If you're a homeowner in Covington, Baton Rouge, New Orleans, or anywhere along the Northshore, here's what you need to know.

🔎 What Is a Slab Leak?

A slab leak happens when a water line beneath the concrete slab of your home cracks, corrodes, or bursts. Since it’s hidden under solid flooring, you won’t see the leak—but the damage can escalate quickly.

Unlike a dripping faucet, slab leaks don’t show up until they’ve already caused thousands of dollars in structural or water damage.

Slab leak repair in progress — what happens when a hidden leak is left unchecked.

🚨 Why You Shouldn’t Wait

Slab leaks are serious. Delaying action can lead to:

• Foundation damage: Water erodes the soil supporting your slab, causing cracks, uneven settling, or shifts in the structure.

• Mold and mildew: Persistent moisture fuels mold growth under your floors or in walls—leading to potential health risks like allergies or respiratory issues.

• High water bills: You could lose hundreds of gallons a day and not even realize it—until the bill shows up.

  
  

🧩 Warning Signs to Watch For

Look for these common signs of a slab leak:

• 📈 Sudden spike in your water bill without any change in usage

• 🌡️ Warm or damp spots on flooring, especially in tile or concrete areas

• 👂 Sound of running water when no taps are on

• 🧱 New cracks in your walls, ceilings, or flooring

• 🌫️ Musty smells that suggest hidden moisture or mold

  
  

If one or more of these signs show up, it’s time to take action.
