Signs and Symptoms of Slab Leaks: What to Look Out For

June 13, 2023

Slab leaks, which occur in the water pipes beneath the concrete foundation of a building, can lead to significant damage if left untreated. Detecting slab leaks early is crucial to prevent structural issues and water wastage. At City Plumbing and Rooter, we can help you recognize the signs and symptoms of slab leaks that homeowners should be aware of to take prompt action and minimize potential damage.

Common Signs of a Slab Leak

There are several signs that can indicate that you have a slab leak, including:

  • Unexplained Increase in Water Bills: One of the initial signs of a slab leak is a sudden and unexplained increase in your water bills. If you notice a significant rise in water costs without any corresponding change in your water usage habits, it could be an indication of a hidden leak beneath the slab.
  • Sound of Running Water: If you hear the sound of running water even when all faucets and appliances are turned off, it could be a sign of a slab leak. The sound may be faint or more noticeable near the affected area. Pay attention to any unusual water-related noises in your home, especially if they persist over time.
  • Damp or Wet Areas on the Floor: Slab leaks can cause moisture to seep through the concrete foundation, leading to damp or wet areas on the floor. You may notice these wet spots in unexpected locations or rooms where water is not typically present, such as hallways or carpeted areas. Check for any discoloration or a noticeable change in texture on your flooring.
  • Hot Spots on the Floor: If the slab leak is in a hot water line, you may feel warm or hot spots on the floor as you walk over them. These hot spots are often localized and indicate that hot water is leaking beneath the surface. Pay attention to any unusual temperature variations in different areas of your home.
  • Cracks in Walls or Flooring: Slab leaks can cause the foundation to shift and lead to cracks in walls, floors, or even the ceiling. Look out for new or widening cracks, especially if they appear near the base of walls or extend horizontally. Cracks accompanied by other symptoms on this list are more likely to be related to slab leaks.
  • Mold or Mildew Growth: Excessive moisture from a slab leak can create a favorable environment for mold and mildew growth. Keep an eye out for any signs of mold or mildew, such as musty odors, visible growth, or an increase in allergy-like symptoms among residents.
  • Low Water Pressure: If you experience a sudden decrease in water pressure throughout your home, it could be due to a slab leak. A leak in the main water line can lead to reduced water flow to your fixtures and appliances.
