| Service | Price | Details |
|---|---|---|
| Retaining Wall Installation | From $30/sq ft | Design and construction of new retaining walls for walkout basements, sloped driveways and terraced yards across the Front Range, built with deep footings, gravel backfill and drainage that stand up to swelling clay and freeze-thaw. |
| Retaining Wall Repair | From $1,500 | Repair of leaning, bowing, cracked or heaving retaining walls, from drainage correction and tieback anchors to partial rebuilds, so a wall pushed by swelling clay and frost is stopped before it becomes a collapse. |
| Retaining Wall Replacement | From $35/sq ft | Full tear-out and replacement of failed or end-of-life walls, including rotting landscape timber and railroad tie walls, with demolition, haul-away, new drainage and engineered materials that handle Colorado clay and frost. |
| Concrete Retaining Walls | From $35/sq ft | Poured concrete and reinforced CMU block retaining walls with footings set below the frost line, rebar and weep holes, the strongest option for tall walls, driveway cuts and tight urban lots in older Denver neighborhoods. |
| Block & Segmental Retaining Walls | From $25/sq ft | Segmental retaining walls (SRW) in Allan Block, Versa-Lok and Keystone systems: mortarless engineered block with geogrid reinforcement that flexes with freeze-thaw, ideal for terraces, curves and garden walls on Front Range lots. |
| Boulder & Natural Stone Walls | From $25/sq ft | Moss rock boulder and natural sandstone retaining walls that blend into foothill landscaping, with machine-placed rock, a compacted base below the frost zone and drainage for a natural, durable Colorado finish. |
| Timber Retaining Walls | From $20/sq ft | Pressure-treated timber walls for garden beds and low terraces, a budget-friendly option, with honest guidance on when timber makes sense in Denver clay and when a longer-lasting material is the better call. |
| Slope Stabilization & Erosion Control | Free estimate | Hillside stabilization with terraced retaining walls, geogrid reinforcement and erosion control, protecting homes, driveways and yards on sloped walkout lots, creek banks and cut-and-fill foothill sites. |
| Retaining Wall Drainage | From $2,500 | Drainage systems that make walls last on Denver clay: French drains, weep holes, gravel backfill and waterproofing that relieve water pressure and frost load, the number one cause of retaining wall failure. |
| Railroad Tie Wall Replacement | From $35/sq ft | Removal and replacement of aging railroad tie and landscape timber walls from the metro's 1970s and 80s subdivisions: creosote-treated tie demolition and haul-away, new gravel backfill and drainage, and a rebuild in segmental block, concrete or moss rock. |
| Leaning & Collapsed Wall Repair | From $2,500 | Priority response for leaning, bulging and collapsed retaining walls after a spring thaw or a summer cloudburst: stabilization with tieback anchors, drainage correction to relieve pressure from wet, swelling clay, and partial or full rebuilds when a wall is past saving. |
What Affects the Price
- Wall Size and Square Footage : Most retaining walls are priced per square foot. Larger walls naturally cost more, but the per-foot rate may decrease on bigger projects due to efficiency.
- Material Type : Different materials have different costs. Timber walls start at $20/sq ft, while concrete and railroad tie walls run $35/sq ft. Natural stone and block walls offer mid-range pricing around $25/sq ft.
- Soil Conditions and Site Accessibility : Difficult terrain, poor drainage, or hard-to-reach locations require extra labor and equipment, which increases the final cost.
- Repair vs. Replacement : Simple repairs start at $1,500, while full replacements are priced per square foot. Leaning or collapsed walls require specialized stabilization and cost from $2,500 up.

Pricing FAQ
Why do retaining wall prices vary so much?
Prices depend on wall height, length, material choice, soil stability, and accessibility. A small timber wall in an easy-to-reach location costs far less than a large concrete wall on a steep slope with poor drainage. Each project is unique, which is why we always provide a custom estimate.
