Factors affecting price within a range

Where your project falls within a price range depends on several site factors. Steep yard access requiring small specialized equipment increases handling effort. Wall height, curve complexity, and total square footage also influence the unit price per square foot. You can view all our covered locations on our service areas page.

Comparing block, rock, timber, and poured walls

Concrete block walls ($15–$40 per sq. ft.) offer excellent strength and uniform aesthetic choices. Timber ($20–$25 per sq. ft.) provides an affordable option for low garden terraces. Natural rock ($45–$65 per sq. ft.) and poured concrete ($20–$45 per sq. ft.) deliver heavy structural retention for steep slopes. We regularly install concrete block retaining walls across local yards.

Pricing for taller and engineered walls

Walls on taller builds require heavy structural reinforcement, geogrid mesh layers, and deep footings. Our rates for engineered retaining walls on taller builds range from $80 to $88 per sq. ft. of wall face due to high structural material demands and extensive earthwork.

Repair, replacement, and drainage pricing

Services for retaining wall repair and replacement along with drainage installations carry no fixed square-foot price. We price these services after inspecting your existing wall, measuring failure extent, and evaluating site access. Every repair estimate is provided in writing.
