| Service | Price | Details |
|---|---|---|
| Retaining Wall Installation | From $30/sq ft | Design and construction of new retaining walls for hillside lots, wash banks, driveways and terraced desert yards, built on footings cut through caliche, with gravel backfill and drainage sized for monsoon cloudbursts. |
| Retaining Wall Repair | From $1,500 | Repair of leaning, bowing, cracked, or settling retaining walls, from drainage correction after monsoon washouts to tieback anchors and partial rebuilds that stop failure before it becomes collapse. |
| Retaining Wall Replacement | From $35/sq ft | Full tear-out and replacement of failed or end-of-life walls, including termite-damaged railroad tie and timber walls, with demolition, haul-away, new drainage, and modern engineered materials suited to desert soil. |
| Concrete Retaining Walls | From $35/sq ft | Poured concrete and reinforced CMU block retaining walls with engineered footings, rebar, and weep holes, the strongest option for tall foothill walls, driveways, pool decks and wash banks. |
| 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, ideal for desert terraces, curved planters and pool-side garden walls. |
| Boulder & Natural Stone Walls | From $25/sq ft | Boulder and natural stone retaining walls that blend into desert and foothill landscaping, machine-placed granite construction with proper base preparation and drainage for a natural, durable 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 desert heat and when a longer-lasting material is the better call. |
| Slope Stabilization & Erosion Control | Free estimate | Hillside and wash-bank stabilization with terraced retaining walls, geogrid reinforcement, and erosion control, protecting homes, driveways, and yards on foothill and cut-and-fill lots. |
| Retaining Wall Drainage | From $2,500 | Drainage systems that make walls last: French drains, weep holes, gravel backfill, and waterproofing that relieve hydrostatic pressure from monsoon runoff and irrigation, the number one cause of retaining wall failure. |
| Railroad Tie Wall Replacement | From $35/sq ft | Removal and replacement of aging railroad tie retaining walls from the 1970s and 80s, creosote-treated tie demolition and haul-away, new gravel backfill and drainage, and a rebuild in segmental block, concrete, or natural stone. |
| Leaning & Collapsed Wall Repair | From $2,500 | Priority response for leaning, bulging, and collapsed retaining walls after monsoon washouts, stabilization with tieback anchors, drainage correction to relieve hydrostatic pressure above caliche, and partial or full rebuilds when a wall is past saving. |
What Affects the Price
- Wall Type and Material : 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 at $25/sq ft. Your choice depends on aesthetics, longevity, and budget.
- Wall Size and Height : Larger walls and taller structures require more materials and labor. We price most installations by the square foot, so a 100 sq ft wall will cost significantly less than a 500 sq ft wall, but the per-square-foot rate remains consistent.
- Site Conditions and Accessibility : Difficult terrain, poor drainage, unstable soil, or limited equipment access can increase costs. Slope stabilization and erosion control projects require custom assessment, so we provide free estimates to evaluate your specific situation.
- Repair vs. Installation vs. Replacement : Simple repairs start at $1,500, while full replacements are priced per square foot like new installations. Leaning or collapsed walls require structural assessment and typically start at $2,500 due to the complexity involved.

Pricing FAQ
Why do retaining wall prices vary so much?
Pricing depends on material choice, wall dimensions, site accessibility, soil conditions, and whether drainage or reinforcement is needed. A small timber wall on level ground costs far less than a large concrete wall on a steep slope with poor drainage. Each project is unique, which is why we provide custom estimates.
Do you offer free estimates?
Yes. We provide free on-site estimates for all retaining wall projects, including slope stabilization and erosion control. Contact us at (480) 494-4792 to schedule your consultation. Our team will inspect your property and provide a transparent quote within 24 to 48 hours.
What payment options do you accept?
We accept all major credit cards, checks, and bank transfers. For larger projects, we can discuss payment schedules. Ask about financing options when you call (480) 494-4792 to discuss your specific project needs.
Are there additional costs I should know about?
Our square-foot pricing includes materials and labor. Additional costs may apply for drainage installation (starting at $2,500), soil stabilization, or extensive debris removal. We always disclose these upfront in your estimate so there are no surprises.
How long does it take to complete a retaining wall project?
Timeline varies based on wall size, material, and site conditions. Small repairs may take a few days, while larger installations can take one to three weeks. We'll provide a realistic schedule in your estimate and keep you updated throughout the project.
