5 Warning Signs You Have a Slab Leak in Your Florida Home

Slab leaks are one of the most common—and most damaging—plumbing issues Florida homeowners face. Because these leaks occur beneath your home's concrete foundation, they often go unnoticed until significant damage has already occurred. Here are five warning signs that you may have a slab leak.

1. Unexplained Spike in Your Water Bill

If your water bill suddenly increases without any change in your usage habits, it's a red flag. A slab leak can waste hundreds or even thousands of gallons of water per month. Compare your current bill to previous months—if there's a significant jump, it's time to investigate.

2. Sound of Running Water When Nothing Is On

Do you hear water running through your pipes even when all faucets and appliances are off? This phantom water sound often indicates a leak somewhere in your plumbing system. If the sound seems to come from the floor or is hard to pinpoint, a slab leak could be the culprit.

3. Warm or Damp Spots on Your Floor

Hot water line leaks can create warm spots on your floor—especially noticeable on tile or hardwood. You might also notice damp areas on carpet or flooring that can't be explained. In Florida's humid climate, these damp spots can quickly lead to mold growth if not addressed.

4. Cracks in Walls or Flooring

When water leaks beneath your foundation, it can cause the soil to shift and your foundation to move. This movement often results in cracks appearing in your walls, baseboards, or flooring. While Florida homes can develop cracks for various reasons, sudden or expanding cracks warrant a leak inspection.

5. Low Water Pressure Throughout Your Home

A significant leak in your main water line can reduce water pressure throughout your entire home. If you've noticed weaker flow from multiple faucets and showerheads, and your neighbors aren't experiencing the same issue, a slab leak may be diverting water before it reaches your fixtures.
