How Much Does a Concrete Block Wall Cost? (2026 Price Breakdown)
Part of Concrete & Masonry
Quick answer
A concrete block wall costs about $10–$22 per square foot installed (blocks, mortar and labor). Standard 8×8×16 blocks run $1.75–$4 each, and a wall takes about 1.125 blocks per square foot plus 3 bags of mortar per 100 blocks.
Block wall cost comes down to three things: the blocks, the mortar, and the labor to lay them. Materials are cheap per piece; the labor of a mason laying course after course is what drives the price. Expect roughly $10–$22 per square foot of wall face installed for a standard CMU wall.
What goes into the cost
| Item | Typical price | Notes |
|---|---|---|
| Standard 8×8×16 block | $1.75–$4 each | ~1.125 per ft² of wall |
| Mortar (70 lb, Type S) | $7–$10 / bag | ~3 bags per 100 blocks |
| Core-fill grout | $6–$8 / 80 lb bag | Reinforced / foundation walls only |
| Mason labor | $65–$95 / hr | Often the biggest line |
| Installed, all in | $10–$22 / ft² | Blocks + mortar + labor |
Example wall costs (standard 8×8×16, installed)
| Wall (L × H) | Area | Blocks | Installed cost |
|---|---|---|---|
| 10 × 8 ft | 80 ft² | 99 | $800–$1,760 |
| 20 × 8 ft | 160 ft² | 198 | $1,600–$3,520 |
| 40 × 8 ft | 320 ft² | 396 | $3,200–$7,040 |
If you're laying it yourself, the material-only cost is far lower — at about $2.75 a block plus mortar, a 160 ft² wall's materials run a few hundred dollars, with the rest being your time. Filling cores with grout and adding rebar for a structural or retaining wall raises both material and labor.
What changes the price
- Reinforcement — rebar and grout-filled cores cost more than a hollow decorative wall.
- Footing — a structural block wall needs a poured concrete footing below frost line.
- Finish — split-face, ground-face or painted/stuccoed block costs more than plain gray CMU.
- Height and access — tall walls need scaffolding; tight sites slow the crew.
- Region and season — labor rates and demand swing the per-square-foot number most.

FAQs
How much does a concrete block wall cost per square foot?
About $10–$22 per square foot of wall face installed, including blocks, mortar and labor. DIY material-only cost is far less — roughly $1.75–$4 per block plus mortar.
How much does one concrete block cost?
A standard 8×8×16 CMU runs about $1.75–$4 each. Thinner 4 and 6-inch blocks cost a little less; 12-inch and specialty (split-face, bond-beam) blocks cost more.
Is a block wall cheaper than poured concrete?
For short walls, block is often cheaper because there's no formwork. For tall or heavily reinforced walls, poured concrete can win on labor. Block also lets you build in stages without renting forms.
How much does it cost to build a 50-foot block wall?
A 50 × 8 ft wall is 400 ft² and takes about 495 blocks. Installed, that's roughly $4,000–$8,800 depending on reinforcement, finish and region.
