What retaining wall costs
Prices in this category are quoted per unit — per square foot, per linear foot, per pier, per job — and the unit is where most quotes become incomparable. The table below is the range we verified in November 2026, with what each line includes.
| Job | Typical range | Notes |
|---|---|---|
| Block wall | $15–$35 / sq ft | Segmental, engineered |
| Poured concrete | $25–$60 / sq ft | Structural |
| Timber wall | $10–$25 / sq ft | Shortest life |
| Gabion | $20–$40 / sq ft | Drainage-friendly |
| Boulder wall | $20–$45 / sq ft | Site-dependent |
| Drainage and backfill | $5–$15 / sq ft | Most failures start here |
What moves the price
- Access. Height, water, tight side yards and finished interiors all add labour.
- Prep. Cleaning, grinding, draining or removing an old system is often the largest hidden line.
- Materials. The same job in a premium finish can double the material cost.
- Permits and disposal. $100–$800 depending on the jurisdiction and the waste stream.
- Season. Spring and autumn are busy; February is not.
What a quote should show
Ask for the same five lines from every contractor: unit price and quantity, prep included, materials by brand, permits and disposal, and the warranty. A quote that only shows a total is a price, not a scope.
The methods hub explains what each option actually does, and the problems hub starts with the diagnosis every quote should follow.
Is the cheapest quote a red flag?
Usually it is a scope difference — less prep, no permit, thinner material. Compare the five lines, not the total.
How long is a quote valid?
30 days is common; material prices move. Ask what happens if you sign after the window.
