Lilburn's homes have a median build year of 1988, and about 26% predate 1980, many on the streets around Old Town. In those houses, leaks tend to start at original valves, at the water heater, and along service lines that have been buried for decades. The City of Lilburn issues its own building permits, and its application lists plumbing among the trades covered, so a service line replacement or rerouted supply will usually go through the city's Planning and Business Services office.
Repair choices once the leak is found
| Finding | Common fix | When replacement makes sense |
|---|---|---|
| Leaking valve or connector | Swap the part | Rarely |
| Pinhole in a supply line | Cut out and splice | If several pinholes have appeared |
| Crack in the yard line | Repair the section | If the line is old or has failed before |
| Slab leak on a hot line | Direct repair through the floor | Rerouting overhead can avoid future slab work |
Signs to look for
- Meter moving with everything off
- A wet or sunken patch between the meter and the foundation
- Peeling paint or swelling trim near a bath
- Water heater cycling overnight
- Higher bills for two or more cycles in a row
Timing and seasonal notes
Run a meter check whenever a bill looks off, and again after a hard freeze, when exposed pipe in crawl spaces and exterior walls can split without leaking until the thaw. In summer, compare readings with irrigation off and on before blaming the house. Gwinnett handles backflow questions at 678.376.4213.
When you call, you'll be connected with an independent plumber who works in Lilburn. Have two meter readings an hour apart and a recent bill handy, and mention whether the house sits on a slab or a crawl space, since that shapes how the search is done.
