Most Summerville homes built from the 1990s onward sit on slab-on-grade foundations, which makes slab leaks a genuinely common local problem rather than a rare one.
What you notice first
- A water bill that jumps with no change in usage
- A warm patch on the floor, which points to a hot line
- The sound of running water with everything turned off
- Unexplained damp on carpet or under flooring
- A water meter that creeps with every fixture closed
Finding it without breaking the floor
This is the part worth understanding before anyone starts. Acoustic listening equipment, pressure isolation and thermal imaging locate the leak to a small area first. That means opening a targeted section of slab rather than exploratory demolition across a room. You do not have to demo your way to a working house, and anyone proposing to start breaking concrete before locating the leak is doing it backwards.
Repair, reroute, or repipe
A single leak on otherwise sound pipe is a spot repair. A line that has failed once and is likely to fail again is often better rerouted overhead, avoiding the slab entirely. Multiple failures on the same system usually mean the material is the problem, and repiping is the honest recommendation even though it is the larger job.
Shut the water off while you decide
A slab leak does not stop, and the damage is cumulative. If you suspect one, close the main and call. That single step limits what this ends up costing you.
