How Slab Leaks Occur
A slab leak occurs when a pipe underneath of the concrete slab of your house and/or building develops a leak. These leaks are often caused due to:
Aging or corroded water pipes
Sub-standard installation and/or construction defects
Migrating soil or foundation movement
High water pressure and/or temperature fluctuations

Due to the reason that the water leak is hidden below concrete, the signs are typically subtle until major damage occurs.
Warning Signs of a Slab Leak
Be wary of the following common signs:
Unexplained spikes within your water bill
Damp spots or warm areas on floors
Cracks in walls or flooring
Sound of running water especially if no faucets are on
Mold or mildew odors
Very low water pressure
If you notice any of these signs, don’t wait! Early detection is crucial for preventing expensive repair and fix.
Why Early Slab Leak Detection Matters
Unchecked slab leaks might lead to:
Foundation water damage: Restoring a foundation can cost tens of thousands of dollars
Structural instability: Eventually, leaks can wear down support structures.
Health hazards: Black mold growth can cause respiratory problems.
High utility bills: Leaks waste lots of gallons of water per month.
Property devaluation: Damage caused due to water leak can significantly lower property value.
Finding water leak early saves both your money and your property.
