Kitchen sink and faucet installation in Lawrenceville runs $450 to $1,650 for a straightforward swap on existing supply lines, and $750 to $2,600 when the supply lines or drain plumbing need rework. Older Lawrenceville ranches off Pike Road and Collins Hill still have original galvanized supply lines that corrode from the inside and restrict flow. We default to replacing those with PEX or 1/2 inch copper on any home older than 1985, and the labor runs an extra 2 to 4 hours per sink.
Sink style in Lawrenceville leans toward workstation sinks for 2026. Stainless 18-gauge workstation sinks with a sliding cutting board and rinse basket are our most-installed model. Farmhouse apron-front sinks are common on the newer Sugarloaf Pkwy builds and the Duluth-side remodels. Standard undermounts still have a place in rental turnovers and tight-budget refreshes along the GA-316 corridor.
The faucet pick most Lawrenceville homeowners regret within 2 years is a bargain-brand big-box pull-down with a plastic cartridge. The cartridges crack from calcium build-up in Gwinnett County water (moderate hardness, about 5 grains per gallon from city supply) within 18 to 30 months. We quote Moen, Delta or Kohler as the floor, with ceramic cartridges that handle Georgia water without issue for 10+ years.
Common failures we fix: undermount sinks that dropped because a previous installer used a weak silicone instead of structural methacrylate adhesive, faucets installed with hand-tight connections that leak slow and ruin the cabinet bottom, and dishwasher drain lines routed without a high-loop or air gap (code requirement in Gwinnett County for anything built after 2010). We install every faucet with wrench-tight connections, every undermount with rated structural adhesive, and every dishwasher with the required air gap or high-loop.
