How to Tell If You Have a Slab Leak in Your Florida Home

Slab leaks are one of the most common plumbing emergencies in Florida homes, yet many homeowners do not recognize the warning signs until significant damage has occurred. Because these leaks happen beneath your concrete foundation, they are hidden from view. Here is how to tell if your Florida home may have a slab leak.

Check Your Water Bill

The most reliable early indicator is your water bill. Compare your current usage to the same period last year. An increase of 10 percent or more without a corresponding change in habits suggests water is going somewhere it should not. Some utility companies offer online portals where you can track daily usage and spot spikes quickly.

Listen Carefully

In a quiet house with all water off, listen for the sound of running water. You may hear a faint hissing from beneath the floor or in the walls. This sound is water under pressure escaping through a crack in the pipe. The sound is often most audible at night when ambient noise is lowest.

Feel Your Floors

Walk barefoot across your floors, especially tile and laminate. Hot spots indicate a hot water line leak beneath the slab. The leaking hot water warms the concrete and the flooring above it. You may also notice areas that feel damp or soft, particularly on carpeted floors.

Look for Foundation Cracks

New cracks in your walls, especially diagonal cracks near doors and windows, can indicate foundation movement caused by a slab leak. Water erodes the soil beneath the slab, causing differential settling that shows up as structural cracking. Also check for doors or windows that have become difficult to open or close.

Perform the Meter Test

Turn off all water in the house and check your water meter. If the flow indicator is moving or the meter reading changes over an hour, you have a leak. This simple test confirms the presence of a leak, even if you cannot locate it visually.
