How to Tell Your Home Has Slab Leaks


Slab leaks are one of the most challenging and potentially damaging plumbing problems you can face as a homeowner. These leaks happen under the concrete foundation of a home, and that makes them difficult to repair—or even locate—unless you’re a plumbing professional. 

The most important thing you need to know about slab leaks as a homeowner is how to tell that you have one in the first place so you can call for our professionals to handle slab leak repair in Fort Walton Beach, FL. Below, we’ve put together a list of the more common warning signs of slab leaks. Don’t sleep on these! You want to take action soon if there’s a possibility of one of these leaks under your home.

Signs of Slab Leaks

1. Unexplained Increase in Water Bills

One of the first signs of a slab leak is a sudden, unexplained increase in your water bill. If your water usage habits haven’t changed but your bill has skyrocketed, it’s time to investigate further. Slab leaks can cause a continuous flow of water, leading to excessive water consumption without your knowledge.

2. Damp or Wet Spots on Floors

If you notice damp or wet spots on your floors, especially in areas that should be dry, this could be a sign of a slab leak. Water escaping from a leaking pipe can seep up through the concrete slab and create moisture on your flooring. This is particularly noticeable on hardwood, carpet, or laminate floors.

3. Warm or Hot Spots on the Floor

In some cases, slab leaks occur in hot water lines. This can result in warm or hot spots on your floor. If you feel an unusual warmth underfoot as you walk through your home, it’s a strong indicator that a hot water line beneath your slab might be leaking.

4. Cracks in Walls and Flooring

Cracks in your walls, floors, or even the foundation of your home can be a telltale sign of a slab leak. As water leaks under the slab, it can cause the soil to expand and contract, leading to shifts in the foundation. These shifts can create stress on the structural components of your home, resulting in cracks.

5. Sound of Running Water

If you hear the sound of running water when all water fixtures are turned off, you might be dealing with a slab leak. This sound is often described as a hissing or whooshing noise and can usually be heard in the quiet of the night when there are no other background noises.

6. Mold or Mildew Smell

Persistent mold or mildew smells in your home can indicate a hidden water leak. Since slab leaks often result in prolonged moisture exposure, they create a perfect environment for mold and mildew growth. 

7. Decreased Water Pressure

A noticeable drop in water pressure can also be a sign of a slab leak. When water escapes from a pipe beneath your foundation, less water reaches your faucets, resulting in decreased water pressure throughout your home.
