| Service | Price | Details |
|---|---|---|
| Retaining Wall Installation | From $30/sq ft | Design and construction of new retaining walls for sloped Philadelphia yards, rowhome driveway cuts, and terraced gardens, built with footings below frost depth, gravel backfill, and drainage for long-term stability. |
| Retaining Wall Repair | From $1,500 | Repair of leaning, bowing, cracked, or heaving retaining walls, from drainage correction and tieback anchors to partial rebuilds of mortared stone 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 rotting railroad tie terraces and crumbling old stone, with demolition, haul-away, new drainage, and modern engineered materials. |
| Concrete Retaining Walls | From $35/sq ft | Poured concrete and reinforced CMU block retaining walls with frost-depth footings, rebar, and weep holes, the strongest option for tall walls, driveway cuts, and tight rowhome lots. |
| 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 frost, ideal for terraces, curves, and garden walls. |
| Boulder & Natural Stone Walls | From $25/sq ft | Boulder and natural stone retaining walls, including the grey Wissahickon schist look of the northwest neighborhoods, machine-placed on a proper base with 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 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 the steep creek-valley lots of northwest Philadelphia and other sloped parcels. |
| Retaining Wall Drainage | From $2,500 | Drainage systems that make walls last: French drains, weep holes, gravel backfill, and waterproofing that relieve hydrostatic pressure and frost pressure, the leading causes 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, with tieback anchors, drainage correction to relieve water and frost pressure, and partial or full rebuilds when a wall is past saving. |
What Affects the Price
- Wall Type and Material : Concrete, block, natural stone, timber, and railroad ties each have different costs. Natural materials and concrete typically cost more than segmental blocks, but offer distinct aesthetic and durability benefits.
- Wall Size and Square Footage : Most retaining walls are priced per square foot. Larger walls naturally cost more, but per-unit pricing often becomes more favorable as project size increases.
- Site Conditions and Soil : Difficult terrain, poor drainage, unstable soil, or steep slopes require additional engineering and preparation work, which can increase the final cost.
- Repair vs. Replacement : Minor repairs start at $1,500, while full replacements are priced per square foot. Our team assesses whether repair is viable or replacement is the better long-term solution.

Pricing FAQ
Why do retaining wall prices vary so much?
Material choice, wall height, square footage, soil conditions, accessibility, and whether you need drainage or erosion control all impact the final price. A 100-square-foot timber wall costs far less than a 500-square-foot concrete wall, and challenging terrain requires more labor and engineering.
Do you offer free estimates?
Yes. We provide free on-site estimates for all retaining wall projects, including installation, repair, replacement, and slope stabilization. Contact us at (445) 278-5117 to schedule your consultation at no obligation.
What's included in your pricing?
Our quotes include labor, materials, site preparation, and basic cleanup. Drainage systems, erosion control, and debris removal may be separate line items depending on your project scope. We'll clarify all costs before work begins.
Do you offer financing or payment plans?
We work with homeowners to discuss project budgets and payment options. Call (445) 278-5117 to discuss your specific situation and explore what works best for your timeline and budget.
Is repair cheaper than replacement?
Often, yes. Minor repairs start at $1,500, while replacement is priced per square foot. However, if a wall is severely damaged, leaning, or collapsed, replacement may be the safer, more cost-effective long-term solution. We'll recommend the best option during your free estimate.
