Frequently Asked Questions
Common questions about our services, coverage area, and process. If you don't see your question, get in touch.
Do I need a permit?
Most residential French drain jobs under 1 acre do not require a permit. Call Fort Mill at 803-547-2034 or York County at 803-909-7200 to confirm for your specific property.
How long does a French drain last?
20 to 40 years with fabric-wrapped pipe. Cecil clay clogs bare perforated pipe much faster, so the fabric sock is not optional in York County.
What causes drainage problems in Fort Mill?
Cecil series soil: sandy loam on top that absorbs rain quickly, then dense red clay underneath that stops water cold. Water has nowhere to go but sideways, toward your foundation.
How deep should a French drain be?
Typically 18 to 24 inches in York County Piedmont soil, to get below the clay Bt horizon. Perimeter drains around foundations may need to go 4 to 6 feet.
How long does installation take?
Most residential jobs complete in 1 to 2 days. Complex multi-zone systems or challenging terrain can take longer.
Where does the water go after a French drain collects it?
To a daylight outlet at lower elevation: a property edge, a street drainage swale, a dry well, or an approved stormwater outlet, often finished with a pop-up emitter. Perimeter drains along the foundation footing route to the same kind of outlet. We confirm legal and functional outlet options before installing.
