What Is a Slab Leak?
A slab leak occurs when the water lines running beneath your home’s concrete foundation develop cracks or holes. Because these pipes are buried under a thick concrete slab, the leak is concealed from plain sight, making it one of the trickiest plumbing issues to detect without professional equipment.
Slab leaks can happen in both fresh water and sewer lines. Left untreated, they can undermine the foundation, cause mold growth, and even compromise your home’s structural integrity.
Why Slab Leaks Happen
There are several reasons a slab leak signs might occur, including:
- Pipe corrosion from contact with soil and concrete
- Shifting soil due to seasonal changes or seismic activity
- Poor installation during original construction
- Abrasion from pipes rubbing against concrete
- Water chemistry issues, such as high acidity or hardness
Understanding the cause helps in both prevention and repair. We use advanced diagnostic tools to pinpoint the cause before recommending the best repair method.
Early Slab Leak Signs Every Homeowner Should Watch For
Spotting a slab leak signs early can make the difference between a quick fix and a major renovation. Here are the top slab leak signs to look out for:
1 Unexplained Increase in Water Bills
If your water bill has suddenly spiked without any noticeable change in usage, you may have a hidden water leak. Over time, even a tiny leak might lose hundreds of gallons.
2 Warm or Wet Spots on the Floor
Walk barefoot around your home—do you feel warm areas on tile or hardwood floors? Warm spots often indicate a hot water line leaking under the slab. Wet spots, especially on carpet, are also major red flags.
3 Sound of Running Water When All Taps Are Off
If you can hear water running or hissing but all fixtures are shut off, there’s a good chance a leak is happening out of sight.
4 Mold Growth or Musty Odors
Persistent moisture beneath flooring can lead to mold growth, even if you can’t see it. Musty smells are often an early warning of slab leak signs of mold spores thriving in hidden areas.
5 Cracks in Walls or Flooring
Water damage beneath your foundation can cause soil shifting, which in turn leads to cracks in your drywall, baseboards, or tiles.
How Hidden Water Leaks Impact Your Home
Hidden water leaks aren’t just inconvenient—they’re costly and dangerous. Here’s why:
- Structural damage: Water can erode the soil under your home, causing the slab to shift or settle unevenly.
- Electrical hazards: Water near wiring can create dangerous short circuits.
- Increased utility costs: Even a small leak can add hundreds to your annual water bill.
In neighborhoods like Southern Highlands, Spring Valley, and Henderson, where many homes sit on expansive clay soil, slab leak signs can be especially damaging due to soil movement.
Health and Safety Risks: Mold and More
One of the most dangerous side effects of a slab leak signs is mold growth. Mold can spread quickly through walls and flooring, triggering allergies, asthma, and other respiratory issues.
If you notice persistent dampness, unexplained health symptoms, or black or green spots near baseboards, it’s crucial to call a professional immediately.
