Water Leak Under Concrete Slab
Hidden Slab Leaks Can Cause Serious Property and Foundation Damage
A water leak under a concrete slab often develops out of sight and can worsen quickly if not addressed. These leaks commonly occur in hot or cold water lines beneath the foundation and may lead to structural damage, mold growth, and excessive utility bills.
Common Signs of a Water Leak Under a Concrete Slab
Warning Symptoms Homeowners Should Take Seriously
- Sudden increase in water bill without increased usage
- High gas bill caused by a leaking hot water pipe under the slab
- Warm areas or hot spots on floors
- Water seeping through floors, tile, grout lines, or slab cracks
- Mold growth on walls, baseboards, or flooring
- Mildew or musty odors appearing suddenly
- Damp flooring or carpet with no visible source
- Sound of running water when all fixtures are turned off
- Low or inconsistent water pressure
Unusual Ant Activity Inside the Home
Unusual ant activity inside the home is a common but often overlooked sign of a slab leak. Ants are attracted to moisture and frequently appear when water is leaking beneath the concrete slab. If ants suddenly show up throughout the home, especially in kitchens, bathrooms, laundry rooms, or near plumbing fixtures, it may indicate a hidden water leak under the foundation.
