Homeowners often pay for decorative stones based on type, thickness, and installation scope. This article covers the cost of stones for landscaping, with clear low, average, and high price ranges, plus practical factors that drive the price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Flagstone (installed) | $6 per sq ft | $10 per sq ft | $15 per sq ft | Thickness 0.75–1.5 in, edge finishing varies |
| River rock (delivered, rough) | $60 per ton | $75 per ton | $100 per ton | 1–2 in average diameter |
| Flagstone (raw material) | $4 per sq ft | $8 per sq ft | $12 per sq ft | Uncut pieces |
| Granite or limestone boulders | $300 each | $600 each | $900+ each | Size varies; delivery may be extra |
| Stone wall veneer (per sq ft) | $2 per sq ft | $3.50 per sq ft | $5 per sq ft | Thin stone faced for walls |
| Delivery/installation minimum | $100 | $180 | $300 | Depends on distance and access |
Flagstone Price Range by Size and Finish
Flagstone costs vary by size, thickness, and finish, with installed prices typically ranging from $6 to $15 per square foot. Larger, thicker pieces and natural split finishes push the price toward the high end. For planning, assume 0.75–1.5 inches thick stone with a natural cleft edge for most walking paths. Labor adds a significant portion when setting irregular pieces. Assumptions: Midwest labor rates, standard patio-grade flagstone, normal access.
Size plays a key role. A 1.0–1.25 inch thick flagstone is common for patios, while 0.75 inch can work for stepping stones but may require moisture barriers and joints. Per-square-foot cost blends material and installation difficulty.
River Rock Landscaping Costs by Unit and Delivery
River rock typically costs $60–$100 per ton including delivery, with 75–125 square feet per cubic yard but actual coverage depends on depth. The most common depth for a mulch-like look is 2–3 inches, which uses roughly 0.5–0.75 cubic yards per 100 square feet. Labor and equipment to spread and rake piles add to the total. Assumptions: Rural delivery, standard 2–3 inch depth, 3-person crew.
Consider whether you need edging or weed barrier along the border, which adds a small, separate cost per linear foot.
Granite and Limestone Boulder Costs by Size
Granite and limestone boulders run from about $300 to $900+ each, depending on size, color, and weight. Ordering multiple boulders may reduce per-unit price but increases delivery complexity. Larger boulders create focal points, while smaller ones fill bed lines. Assumptions: Single delivery to a paved or gravel entry, standard grading.
Delivery often requires equipment and may be charged separately; estimate $100–$500 for a typical local move, with longer hauls pushing higher.
Stone Wall Stone Rates by Type and Project Scope
Stone wall veneer or full-dimension wall stones may cost $2–$5 per square foot, depending on rock type and wall height. Veneer provides a cost-efficient option for accent walls, while full-dimension stacks demand heavier labor and equipment. Assumptions: 2–3 person crew, 8–12 hour day, standard 6–8 inch wall thickness.
Material choices affect maintenance and moisture management, influencing long-term cost through sealants and repointing around joints.
Delivery, Lift, and Installation Fees for Stonework
Delivery, lifting, and installation fees commonly add $100–$300 to a project, driven by distance and access. Narrow driveways, stairs, or steep grades raise both time and equipment needs. Assumptions: Local market with standard curbside delivery and a moderate-grade site.
Equipment rental or subcontracted crane work may appear in high-demand seasons, shifting the overall cost curve.
Regional Price Variations Across the United States
Prices differ by region due to quarry proximity, transport costs, and labor rates, with coastal markets often higher than inland areas. In the West, expect top-tier stone options and higher delivered costs; the Southeast frequently offers competitive stone pricing and faster availability. Assumptions: Non-urban market in each region, typical project scope.
For budgeting, compare a few regional quotes and note how delivery distance and driveway access change the final tally.
Labor Time and Crew Size for Stone Landscaping Projects
Labor costs reflect crew size and hours; typical installed labor ranges $50–$120 per hour per crew, depending on skill and terrain. Larger projects with intricate layouts require more crew hours and may qualify for volume discounts on material purchases. Assumptions: 2–3 person crew, standard site preparation, no major site obstacles.
Plan for drying time and joint maintenance if using mortar-set flagstone, which can extend installation time and cost.
Cost-Reduction Tactics: Substitutions and Prep Work
Smart substitutions and thorough prep can lower total costs, such as using quarried stone with better yield or choosing a thinner flagstone option. Pre-cut shapes and flat cuts ease installation, cutting labor time. Assumptions: Moderate access, weather window within project season.
Optimize by batching deliveries, aligning with other outdoor projects, and avoiding unnecessary upgrades that don’t improve function or curb appeal.
| Cost Components | Materials | Labor | Equipment | Delivery | Permits | Warranty |
|---|---|---|---|---|---|---|
| Typical ranges | $2–$8 per sq ft | $50–$120 per hour | $20–$60 per hour rental | $100–$300 | $0–$200 | $0–$200 |
| Subtotal example | $6 per sq ft | $90 per hour (2 workers) | $40 per hour | $150 | $0 | $0 |
