Retaining wall cost in Chester County ranges from $30 to $90+ per linear foot installed, depending on height, material, and drainage requirements. A 20-foot natural stone wall at 3 feet high typically runs $3,000–$5,000. Walls over 4 feet or walls requiring engineering review add 20–40% to the base cost. Drainage aggregate, perforated pipe, and filter fabric are structural requirements — not optional add-ons — and are included in our pricing.
