Homeowners typically pay for decomposed granite (DG) by area with costs driven by material quality, base prep, and installation complexity. The price range shown here reflects typical U.S. pricing for residential paths, patios, and driveways, including per-square-foot and per-ton estimates. Readers will see concrete figures for budgeting and quoting purposes.
DG price and install costs can vary widely by region, access, and base preparation requirements, so use the ranges as planning benchmarks rather than fixed quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| DG material (per sq ft, loose DG) | $0.50 | $1.50 | $2.50 | Most common sizes: 1/4″ to 3/8″ minus calcined DG |
| DG material (per ton, delivered) | $30 | $60 | $100 | Typically yields ~80-100 sq ft at 2 inches deep per ton |
| Base prep (compacted aggregate or soil stabilization) | $1.00 | $2.50 | $4.00 | Site-dependent; includes grading and compaction |
| Labor for installation (per sq ft) | $2.00 | $4.50 | $8.00 | Includes material spreading and compacting |
| Edging and edging materials (per linear ft) | $1.50 | $3.50 | $6.00 | Plastic, metal, or concrete edging |
| Delivery/Hauling (per trip or per load) | $50 | $150 | $350 | Depends on distance and load size |
| Sealer or stabilizer (optional, per sq ft) | $0.10 | $0.25 | $0.60 | Not always required for DG surfaces |
| Permits and inspections | $0 | $100 | $500 | Regional variance; may be waived in some areas |
| Maintenance (annual, per sq ft) | $0.05 | $0.15 | $0.30 | Weed control, rebedding, top-up DG |
| Total project (typical 200-300 sq ft area) | $1,000 | $3,000 | $6,500 | Depends on depth, base, and edging |
Price Range for Decomposed Granite by Project Size
Small paths (100-150 sq ft) typically range from $800 to $2,000, while larger patios or walkways (300-600 sq ft) can run $2,500 to $8,000. The per-square-foot price often falls as area grows, due to base efficiency and delivery costs being spread across a larger area.
Assumptions: Midwest or South regions with standard 2-inch DG depth, standard base, no decorative stamping, and basic edging. Labor hours scale with area and access conditions.
Major Cost Elements in Decomposed Granite Installations
Material costs plus base preparation are the dominant drivers, with labor and delivery shaping the final bill. A typical project combines DG material, compacted base, edging, and labor for spreading and compacting. The table below shows the share of the total price by component for a mid-range job.
| Component | Share of Total | Typical Range | Unit |
|---|---|---|---|
| DG material | 25-40% | $0.80-$2.00 | per sq ft |
| Base prep | 20-35% | $1.00-$3.00 | per sq ft |
| Labor (spreading/compaction) | 25-40% | $2.00-$5.00 | per sq ft |
| Edges and border | 5-15% | $1.50-$6.00 | per linear ft |
| Delivery | 0-10% | $50-$300 | per load/booking |
| Permits/inspections | 0-5% | $0-$500 | flat |
Regional Variations That Affect Decomposed Granite Price
Coastal markets with stricter permitting and higher labor rates typically push costs higher. In coastal California, expect higher base prep and delivery charges, while inland Southern states may show lower delivery costs but similar material prices. The table captures typical regional deltas in cost per square foot.
Per-Square-Foot and Per-Ton Pricing for DG
Per-square-foot pricing is the most common budgeting method for DG projects because it aligns with area-based planning. A mid-range DG installation typically runs $1.50-$3.50 per sq ft delivered and spread, excluding edging. If DG is purchased by the ton, expect $40-$90 per ton including delivery, with coverage around 80-100 sq ft at 2 inches deep per ton depending on compaction and compaction loss.
Labor, Installation Time, and Equipment in DG Projects
Labor hours vary with area, subgrade condition, and equipment access; crews of 2-3 finish a typical 200-300 sq ft job in a day. Equipment such as a plate compactor, rake, and wheelbarrows are standard. Expect higher costs for tight spaces or slopes where hauling is difficult.
Common Add-Ons and Maintenance Costs for DG Surfaces
Top-ups, weed control, and border replacement add recurring costs over time. Sealing or stabilizing DG is optional and often used in high-traffic areas or where weed growth is a concern. Maintenance typically includes regrading and replacing top-layer DG every 3-7 years, depending on foot traffic and rainfall exposure.
Alternatives and Substitutes to DG and Their Costs
A compacted crushed stone or pea gravel can be similar in price but differs in stability and permeability. Paver patios offer a more durable solution with higher upfront costs, while plain soil paths are cheaper but may require more ongoing maintenance. Compare per-square-foot costs and long-term durability when evaluating options.
Ways to Cut DG Costs Without Sacrificing Quality
Control scope, optimize timing, and choose durable edging to reduce long-term expenses. Plan projects during cooler months to reduce labor delays, order DG and base materials in bulk, and reuse existing edging where feasible. Selecting standard, readily available DG colors without decorative blends saves material costs, while preparing a uniform, well-compacted base minimizes future maintenance.
Regional pricing snapshot
To help budget across markets, consider this compact view: coastal zones often run toward the high end of per-sq-ft pricing due to labor and delivery, while inland regions may offer more favorable rates. Always confirm access, slope, and base depth to avoid mid-project changes.
| Region | DG Material (per sq ft) | Delivery/Hauling (per load) | Labor (per sq ft) | Notes |
|---|---|---|---|---|
| Coastal California | $1.80-$2.50 | $200-$350 | $3.50-$6.00 | Higher permitting and wage scales |
| Southwest urban | $1.20-$2.00 | $100-$250 | $2.50-$5.00 | Clear weather enables steady progress |
| Midwest suburban | $1.00-$1.80 | $80-$180 | $2.20-$4.50 | Moderate costs and access |
| Southeast rural | $0.90-$1.60 | $60-$120 | $2.00-$4.00 | Often best value for larger lots |
