A slab leak in Lillington is a supply pipe leaking under a concrete floor, and the Town is clear that it won't work on private lines past the meter. A plumber locates the leak, then repairs that section through the slab or replaces the buried run with a new line above.

What's different in Lillington
Lillington has grown fast. Over 45% of its homes have been built since 2010 and the median home dates to 2005, yet about 31% were built before 1980, per Census survey data. That gives the town two kinds of slab leak: newer homes where a fitting or a damaged length of pipe fails, and older houses near the Cape Fear River and downtown where pipe has simply aged. Older houses in the area were often built on crawl spaces, with slab sections in additions and garages.
The Town of Lillington buys Cape Fear River water from Harnett Regional Water and distributes it, with chloramine disinfection (highest running average 2.5 ppm in the 2024 report). Town crews work on lines in the right-of-way but not on private lines past the meter, and the town says the line between the meter box and the home needs a plumber. Vandercroft and RiverBluff are separate small town water systems, but the same principle applies to your side of the meter.
Comparing the fixes
| Approach | Best for | Keep in mind |
|---|---|---|
| Repair through the slab | A single, well-located leak in pipe that's otherwise sound | Flooring and concrete over the spot must be removed and restored |
| Reroute the line | Leaks under tile or cabinets, or pipe showing wear | New pipe runs through walls or the attic, so some drywall gets cut |
| Replace several runs | Older homes with repeat leaks | A bigger job, but it can stop the cycle of one leak after another |
Signs to look for
- The meter at the meter box keeps moving with no water in use
- A noticeably warm area on the floor
- Water bills higher than normal for the season
- Damp or discolored flooring along an inside wall
- Faint trickling or hissing under the floor at night
Timing tips
Fall and winter make hot-water slab leaks easier to feel, while summer watering can hide a leak on the bill. If you do a meter test, turn off outdoor taps and irrigation first. Inside town limits and the ETJ, Lillington Planning and Inspections handles building inspections; outside that area, Harnett County Inspections handles permits.
