French Drain & Drainage FAQ

A French drain is a perforated pipe set in a gravel-filled trench wrapped in geotextile fabric. Water in the surrounding soil flows into the gravel, enters the perforated pipe, and is carried by gravity to a lower discharge point — relieving saturation and hydrostatic pressure.

Cost depends on length, depth, soil conditions, and the discharge solution your property requires. We provide a fixed, written quote after an on-site assessment — not a per-foot guess over the phone. Call 346-522-4469 to schedule yours.
