1. Unexplained High Water Bills
If your water usage hasn’t changed but your bill keeps climbing, you might have a slab leak. A small pinhole leak can waste hundreds of gallons per day. Check your water meter when all fixtures are off. If the dial keeps moving, water is escaping somewhere underground.
2. Warm Spots on Your Floor
Hot water line leaks create warm areas on your floor that feel like heated bathroom tiles. These spots often appear in hallways or living areas away from plumbing fixtures. The heat radiates through the concrete slab and can be felt even through carpet or tile.
3. Damp Carpets or Flooring
Moisture seeping through the slab creates damp spots that won’t dry. You might notice your carpet feels wet in certain areas or hardwood floors start buckling. This moisture can lead to mold growth within 24-48 hours in Alamo Heights’ humid climate.
4. Foundation Cracks or Heaving
Water under your slab erodes the soil supporting your foundation. You might see new cracks in walls, doors that stick, or visible foundation movement. The clay soil in Alamo Heights expands when wet, causing additional stress on already compromised plumbing.
5. Low Water Pressure
A slab leak diverts water from your fixtures, reducing pressure throughout your home. If you notice weak flow at multiple faucets or showerheads, especially when other fixtures are running, you could have a significant underground leak..

6. Running Water Sounds
Listen for the sound of running water when all fixtures are off. Place your ear against walls or floors near suspected areas. The sound might be faint but persistent. This indicates water escaping from pressurized pipes beneath your slab.
7. Mold or Mildew Odors
Hidden moisture creates perfect conditions for mold growth. If you notice musty odors that persist despite cleaning, especially in areas away from bathrooms or kitchens, you might have a slab leak feeding mold colonies under your floor.
