Slab Leak Assessment
A slab leak is a supply or drain line that has failed beneath a concrete floor. Because it's hidden, the signs are indirect — a warm spot on the floor, a higher water bill, or dampness at the slab edge. Slab leak assessment locates it precisely so the opening is small and the repair is targeted.
Common reasons you may need this service
- A floor is warm in one spot.
- Your water bill has climbed without explanation.
- You hear running water when nothing's on.
- There's dampness or cracking at the slab edge.
- A prior leak suggested a slab issue.
Typical tasks and considerations
- Reviewing symptoms and meter behavior.
- Isolating lines to narrow the area.
- Locating the leak under the slab.
- Marking the spot for a targeted opening.
- Outlining repair options.
Common problems and possible causes
Warm floor spot
A hot-water line leak under the slab warms the concrete above. Locating it limits how much floor is opened.
Rising bill, no visible leak
A slow slab leak can run quietly. Meter behavior and isolation help pinpoint it.
Cracking or dampness
Water under the slab can affect the concrete and nearby walls. Catching it early limits structural impact.
