Landscaping boulder cost factors
The following factors impact the cost of landscape boulders:
Stone size & quality: Large landscape boulders over 36" cost the most because they are the most difficult to quarry and transport. Smaller landscaping rocks cost less and can be delivered by the truckload. The stone quality also impacts the price, with smooth, high-quality boulders at the top of the range.
Stone type: Common landscaping boulder types include granite, limestone, sandstone, basalt/lava rock, and gneiss. Due to landscaping boulders' weight and the high cost of transporting them across long distances, some stone types are only available in specific regions and prices will typically be the lowest for stones quarried in your area.
Quantity: Most suppliers price their landscape boulders by the ton, though some suppliers price smaller stones by the cubic yard or by the full pallet. Check with the supplier to confirm whether they have a minimum order size for delivery.
Delivery fees: Landscape boulder delivery costs $50 to $400+, depending on the distance and the stone size and total weight.
Site prep & installation:
Leveling or grading: Regrading a yard costs $0.40 to $2.00 per square foot to ensure the area is level or properly graded for drainage before installing landscape boulders.
Installation labor: Landscaping companies charge $25 to $50 per hour per person for labor. DIY installation saves on labor costs but can be challenging for large, heavy boulders.
Removing or relocating existing rocks: Landscape rock removal costs $50 to $200 per cubic yard to relocate the rocks within the same property or $220 to $250 per cubic yard to remove them and haul them away.
