Six things that move the price
Material options
| Option | Notes |
|---|---|
| Segmental concrete block | Most common, DIY-feasible for short walls |
| Timber | Lower cost, shorter lifespan than masonry |
| Poured concrete | Highest strength, formed on-site |
| Natural stone | Premium appearance, highest labor cost |

Regional labor rates and permitting requirements move this estimate by as much as 65% between the least and most expensive metros in our dataset.
Can you DIY part of a retaining wall construction?
Retaining Wall Construction sits in the middle ground: some parts of the job (demo, prep, finish work) are DIY-feasible, while the technical core is best left to a licensed pro. A hybrid approach can capture a meaningful share of the roughly 30% potential labor savings without taking on the riskiest part of the job.
Retaining Wall Construction FAQ
How much does a retaining wall construction cost?
Retaining Wall Construction costs $2,000–$8,000 nationally, averaging $3,500 for a typical 100 sq ft (face area) scope. The number varies by metro — see the city breakdown above, or use our calculator for a localized figure.

What's included in this retaining wall construction estimate?
The estimate covers the full scope of a typical project: primarily materials (40%), labor (35%), drainage system (15%), plus the remaining categories shown in the cost breakdown above. See our methodology for exactly how these figures are built.
What's the difference between budget, mid-range, and premium options?
Material tier is the single biggest lever on price within a retaining wall construction. See the material options table above — generally, budget options run near the low end of the range, premium materials push toward or beyond the high end.
What most affects the price of a retaining wall construction?
Two of the biggest levers: material — segmental block, timber, poured concrete, or natural stone, and wall height (walls over roughly 4 feet typically need engineering). See the full factor list above for everything that can move your number.
