Lawrenceville’s older housing stock in the Lawrenceville Historic District and along Old Peachtree often contains galvanized or early copper lines that corrode from decades of mineral-rich well water and shifting clay soils. When these lines fail, we map the run, isolate the section, and pull new PEX or type-L copper through existing chases to limit drywall damage. Gwinnett County code requires dielectric unions at material transitions and pressure testing at 100 psi before walls are closed.
Newer subdivisions in Sugarloaf and Lawrenceville Village frequently need slab-leak repairs after tree-root intrusion or seasonal ground movement during heavy summer rains. We use acoustic listening and thermal imaging to locate the leak, then reroute with Uponor PEX-A to avoid future slab cuts. Exterior mains serving homes near Tribble Mill Park often sit in wet, low-lying soil that accelerates corrosion on galvanized services from the 1970s.
Whole-house repipes in Gwinnett County homes built before 1990 usually take two to three days and require coordination with the city’s 3/4-inch minimum meter supply rule. We protect finished surfaces with floor runners, install new shut-off valves at every fixture, and flush the system thoroughly before restoring hot-water service. Nearby cities such as Duluth and Suwanee share the same soil and water chemistry, so the same material choices apply across the county line.
Technician insight
In Lawrenceville the thing that catches most people out with Pipe Replacement is the combination of 1960s–1970s galvanized lines and the heavy red clay around the Lawrenceville Historic District; once one joint starts weeping, the next one usually follows within months because the soil holds moisture against the pipe.
Slab Leak in Lawrenceville Village
A homeowner near Lawrenceville Village reported warm floors and low pressure after summer storms. Camera inspection found a pinhole in the original copper under the slab. We rerouted the run with PEX-A through the attic, restored full flow the same afternoon, and left the slab intact.

How it works
- 1
On-Site Assessment
We arrive at the Lawrenceville address, shut off the main, and use camera and pressure testing to map the failed section and note any additional weak points.
- 2
Material Selection and Quote
We discuss PEX versus copper options, confirm Gwinnett County permit requirements, and provide a written scope before any work begins.
- 3
Removal and Installation
Old piping is cut out, new lines are run through protected chases or rerouted, and all connections are made with manufacturer-approved fittings.
- 4
Testing and Restoration
The system is pressurized, inspected for leaks, and returned to service; drywall access points are left ready for the homeowner’s contractor if needed.
Pricing
Upfront written estimates after inspection; final price depends on access, material choice, and whether rerouting avoids slab work.
