A French drain is a gravel-filled trench with a perforated pipe that collects groundwater and carries it away from your house by gravity. Los Angeles gets most of its rain in a handful of winter storms, and on hillside lots, that water has to go somewhere fast. Without a French drain system, it settles against foundation walls, floods low spots in the yard, and seeps under garages and lower-level floors.

French drain installation is the long-term fix, and repair and cleaning keep an existing drain moving water after years of silt, roots, and crushed pipe. We handle all three, so you don’t need a separate contractor for each.
