Prices for a decomposed granite patio typically reflect material costs, base preparation, and installation labor. The total cost usually falls in a range from indirect low-cost installs to more durable, feature-rich patios. The main cost drivers are patio size, depth of DG, edging, and site accessibility.
Assumptions: Midwest labor rates, standard DG material, normal access, no major site obstruction.

| Materials (decomposed granite and base) | $0.80 | $2.50 | $4.50 | Per sq ft; prescreened and compacted DG needed |
| Delivery/Transport | $0.25 | $0.75 | $2.00 | Per sq ft depending on distance |
| Sub-base/Base Layer (gravel, fabric) | $0.50 | $1.50 | $3.00 | Includes geotextile fabric where required |
| Edge Restraints/Edging | $0.50 | $2.00 | $5.00 | Plastic, metal, or stone edging |
| Labor (preparation, settlement, compaction) | $1.50 | $3.50 | $6.00 | Per sq ft; varies by crew size |
| Permits/Inspections | $0 | $1.00 | $3.00 | Region-dependent |
| Decorative/Accessories | $0.20 | $1.00 | $2.50 | Stains, sealers, or stabilizers |
What Buyers Typically Pay For a Decomposed Granite Patio
A typical DG patio costs between $2.50 and $6.50 per square foot for a basic installation, with total projects commonly ranging from about $1,200 to $5,000 for 500 square feet. On larger or more refined sites, the price can climb to $8 per sq ft or higher when high-end edging, extra base, or decorative color is added. Most projects fall in the $2.80-$5.50 per sq ft window when mid-range materials and standard edging are used.
Assumptions: 8–12 inch base, compacted DG, standard access, and no structural site work.
Major Cost Components in a Decomposed Granite Patio Quote
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $0.80 | $2.50 | $4.50 | DG plus base aggregate |
| Labor | $1.50 | $3.50 | $6.00 | Site prep, compaction, leveling |
| Equipment | $0.15 | $0.50 | $1.50 | Compactor, rake, wheelbarrow |
| Delivery | $0.25 | $0.75 | $2.00 | Material transport to site |
| Permits/Inspections | $0 | $1.00 | $3.00 | Local requirements |
| Edge/Restraints | $0.50 | $2.00 | $5.00 | Can be plastic, metal, or stone |
| Sealer/Color/Finish | $0.25 | $0.75 | $2.50 | Optional for color or sealing |
Assumptions: Standard 8–12 inch base, typical climate, and no heavy excavation.
Variables That Drive a Decomposed Granite Patio Price
Depth of the DG layer is a primary driver: 2 inches is common for leveling, while 4 inches or more raises material and compaction costs. Surface area and shape affect both material and labor; irregular footprints increase edging and prep time. Regional climate affects base choice and sealing needs, with wetter regions often needing better drainage and fabric underlayment. Project size, edging type, and base depth are the top three price levers.
Assumptions: Moderate slope, accessible site, standard edging, and no rock removal.
Ways to Cut Costs on a Decomposed Granite Patio
Scope control: limit edge complexity and avoid custom curves; batch DG to reduce waste. Material choices: select standard gray or tan DG rather than dyed or stabilized blends. Timing: schedule in dry seasons to minimize delays and weather-related labor time. Comparison: obtain multiple quotes using a consistent scope. Bundling: combine DG patio with adjacent hardscape to optimize delivery and equipment use. Careful scope management can reduce total costs by 15–25% in many cases.
Assumptions: No major site issues; standard color and stabilization not required.
Regional Price Differences for Decomposed Granite Patios
Coastal metros tend to have higher labor and delivery costs, while rural regions may offer lower rates but longer project times. On the West Coast, expect a 5–15% premium for materials and permits compared with the Midwest, while the Southeast often shows mid-range pricing with variable edging costs. Regional delta can swing total price by 10–30% depending on distance and labor market.
Assumptions: Typical urban, suburban markets; no rush scheduling.
Labor Time and Crew Size for DG Patio Projects
A small 100–200 sq ft DG patio commonly uses a two-person crew for 1–2 days, while larger 400–600 sq ft installations may use three to four workers over 2–4 days. If a contractor includes site prep, edging, and sealing, labor hours increase accordingly. Labor can constitute about 30–60% of total costs depending on scope.
Assumptions: Standard access; no heavy excavation or utility conflicts.
Size and Depth: How Project Scope Impacts Price
Doubling the patio area roughly doubles material and edging costs, but labor scales differently depending on crew efficiency and site setup. A 10×10 foot patio with 2 inches of DG may cost as little as $1,800, while a 20×20 foot patio with 4 inches of DG, edging, and sealer can approach $8,000 or more. Size and depth are the most predictable price drivers for DG patios.
Assumptions: Standard edge, no decorative finishes, mid-range DG material.
