Engineered retaining walls commonly price in the tens of dollars per square foot of wall face, driven by height, material, access, and the drainage system behind the wall. Small landscape walls land in the low thousands; structural replacements reach five figures. Every quote here is written and fixed.

Retaining wall pricing scales with physics: the pressure behind a wall grows quickly with height, so cost per square foot of face rises as walls get taller, and a wall twice as tall is much more than twice the wall. The drivers stack predictably. Height and surcharge: a 3-foot garden terrace and a 6-foot cut holding a driveway above it are different structures, and anything over about 4 feet, or under a surcharge at any height, carries engineered design as both good practice and a permit requirement in most corridor cities. Material: segmental engineered block, poured concrete, and stone facing price differently, and the right choice follows the height, the look, and the budget. The invisible system: free-draining backfill, filter fabric, a perforated drain that daylights, and weep holes are a real share of the cost and the entire reason the wall will still be plumb in fifteen years; a bid that is silent on drainage is a bid for a future lean. Demolition: replacing a failed wall adds tear-out and haul-off, and failed walls usually failed because the drainage was never built, so the rebuild includes what was missing. Access moves labor: a walk-out backyard versus a lake slope at Kiowa or Texoma changes the equipment story. The free walkthrough measures all of it, and the written quote prices the wall you actually need, drainage included.
