Well Drilling & Repair in Lexington, SC

Lexington County Well Service

Lexington County Is Hard Rock Country. You Need a Rig Built for It.

Lexington County sits west of the Congaree, which puts almost all of it firmly on the Piedmont side of the Fall Line. Underneath the topsoil and the weathered saprolite is crystalline bedrock — granite, gneiss and schist. It is dense, it is old, and it does not hold water the way sand does.

That distinction matters more than most homeowners expect. In a Coastal Plain sand well, water sits in the pore space between grains and you can predict roughly what you will get. In Lexington County bedrock, water moves through fractures — cracks in otherwise solid rock. Hitting a good well here means intersecting a productive fracture system, and that is a matter of reading the site properly rather than simply drilling deeper. A 300-foot well that crosses two good fractures will out-produce a 500-foot well that crossed none. Sixty-six years of drilling this specific county is how we know where to set up.

Above the rock there is usually 40 to 80 feet of saprolite — rock that has weathered in place into something closer to clay. That has to be cased off properly, both to keep the borehole from collapsing and to keep surface water out of your drinking water. Casing depth is not a corner worth cutting, and it is one of the places where a cheap quote often turns out to be cheap for a reason.

Lexington County has also grown fast — Red Bank, Gilbert, Pelion, Swansea and the Lake Murray side around Chapin have all seen substantial new construction on rural lots without county water lines. Those properties need a well and a septic system, and we are licensed for both jobs, which saves coordinating two contractors around one build schedule.
