What are the most common slab leak symptoms in a home?

The most common slab leak symptoms in a home show up as floor abnormalities, unexpected water use, reduced water pressure, or new foundation clues. These appear when a pressurized water line beneath the concrete cracks and water migrates into the slab and flooring. We use electronic, non-invasive leak detection and camera tools, the same approach we bring to homes around Urbana. If the water heater seems to run when no hot water is used, that often points to a hot-side slab leak.

Call a pro if you notice any of these specific signs:

• Unexplained spike in your water bill or meter moving with all fixtures off
• Warm or hot spots on tile or concrete floors
• Damp carpet, cupped wood, or musty odors along baseboards
• Noticeable drop in water pressure with no visible leak

If you suspect a slab leak, shut off water at the main and schedule professional leak detection promptly.
