Savannah's beautiful neighborhoods sit on some of the most challenging drainage terrain in the Southeast. The combination of historic lot grading, mature tree root systems, clay-heavy coastal plain soils, and a high seasonal water table creates persistent drainage problems that surface-level fixes can't solve. Our vetted contractors install properly engineered French drain systems throughout Savannah — from the Historic District to Ardsley Park, Sandfly, and Georgetown.

Common Questions from Savannah Homeowners

How deep do French drains need to be in Savannah?

Due to Savannah's high water table and clay subsoil layer, French drains typically need to be installed 18–24 inches deep to intercept groundwater effectively. Shallower installations in Savannah's coastal soils often fail to reach the saturated zone.

Will a French drain work in Savannah's clay soil?

Yes — but only if the native clay is excavated and replaced with proper ASTM C33 #57 washed stone. Backfilling with native clay defeats the purpose entirely and is the most common reason French drains fail in the Lowcountry and coastal Georgia.

How much does a French drain cost in Savannah?

Most residential French drain installations in Savannah range from $1,500 to $6,000 depending on linear footage, depth, soil conditions, and discharge routing. Commercial and larger systems run higher.
