Stabilized decomposed granite typically costs $4-$10 per square foot installed, with many residential paths, patios, and seating areas landing near $6.50 per square foot. Stabilizer type, excavation, base depth, access, and local labor rates can move a quote substantially; DIY material-only projects are often less expensive.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed surface | $4/sq ft | $6.50/sq ft | $10/sq ft | Prepared site, compacted DG and stabilizer |
| DIY materials | $1/sq ft | $2/sq ft | $3.50/sq ft | Delivery and tools may be extra |
| 300-sq-ft patio | $1,200 | $1,950 | $3,000 | Before unusual drainage or access work |
| Stabilized DG material | $40/ton | $75/ton | $120/ton | Local quarry, color, and stabilizer affect price |
What a stabilized DG path or patio usually costs
For a standard residential installation, budget about $4-$10 per square foot, including typical site preparation, aggregate, stabilizer, placement, and compaction. A 200-sq-ft garden path may cost $800-$2,000, while a 500-sq-ft patio may run $2,000-$5,000. Assumptions: standard tan or gold DG, ordinary access, compacted base, and no major drainage correction.
A practical planning figure is $6-$7 per square foot for a straightforward contractor-installed surface. Material-only pricing is not directly comparable to an installed quote: labor, base stone, edging, delivery, and excavation may account for a large share of the total. Very small jobs can exceed the typical per-square-foot range because crews often charge a minimum mobilization fee.
How aggregate, labor, and base work shape the quote
Quotes differ in what they include. Ask whether the stated price covers excavation, hauling, base aggregate, stabilizer, compaction, and cleanup. Labor is often calculated by crew hours, while material is priced by ton or delivered load.
| Quote component | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| DG and stabilizer | $0.75-$2.50 | Per sq ft | Stone color, grading, stabilizer product |
| Base aggregate | $0.50-$1.75 | Per sq ft | Base depth and subsoil condition |
| Installation labor | $2-$5 | Per sq ft | Access, layout, crew size, compaction |
| Excavation and disposal | $0.50-$3 | Per sq ft | Dig depth, soil volume, haul distance |
| Edging and delivery | $150-$900 | Per project | Perimeter length and delivery distance |
Preparation and labor can cost as much as, or more than, the DG itself. A thin decorative layer over an unsuitable surface may fail, so compare quotes by the complete installation specification rather than the aggregate price alone.
Why depth, slope, and stabilizer type change the price
Surface depth is a major material driver. A 2-inch compacted layer uses less DG than a 3-inch layer, while a path intended for frequent foot traffic may need a deeper, well-compacted base. Steeper slopes, soft soil, and areas that collect water can require grading, drainage, or retaining work beyond a basic quote.
Stabilizer formulation also matters. Some products are blended into the aggregate; others are applied during installation. The selected DG gradation, color, and binder affect material cost and finished appearance. Get the proposed compacted surface depth and stabilizer method in writing. An estimate that omits either detail is difficult to compare accurately.
Regional labor rates and delivery distances affect installed prices
In markets near quarries and with moderate labor costs, straightforward work may fall near $4-$7 per square foot. High-cost metropolitan areas can run about 15%-35% above that range; remote sites may also pay more when aggregate delivery is long or a small load triggers a minimum charge. These are broad comparisons, not fixed regional tariffs.
Ask contractors to separate delivery from installation. A nearby source may reduce hauling charges, but the cheapest DG is not automatically suitable for a stabilized surface. Local labor availability and truck access can matter as much as the listed price per ton. Narrow gates, stairs, or long wheelbarrow routes may add handling time.
Installed stabilized DG versus loose gravel or DIY work
Loose decomposed granite without stabilizer can cost roughly $2-$6 per square foot installed, depending on base preparation and edging. It may shift more readily and need more frequent raking. Stabilized DG typically costs more upfront but creates a firmer surface when installed and maintained correctly. Pavers and concrete are different products and can cost substantially more, especially where labor and finish work are extensive.
DIY installation may bring material costs to about $1-$3.50 per square foot, but buyers still need base material, compaction equipment, delivery, edging, and suitable drainage. Renting a plate compactor may add roughly $75-$150 per day. DIY savings are greatest on a small, level site that can be reached by delivery equipment.
Which site add-ons can push a DG project past budget
Removing existing concrete, roots, or deep turf can add about $1-$5 per square foot, depending on thickness, equipment access, and disposal fees. Basic edging commonly adds $5-$20 per linear foot installed, with material and layout influencing the rate. Drainage improvements can add several hundred dollars or more when grading or pipe installation is needed.
Delivery may be a separate $100-$400 charge for a small local load, with longer distances or difficult unloading increasing the fee. Small-project minimums of roughly $300-$800 are possible. Check whether the estimate includes haul-away, delivery, edging, and final compaction. Those exclusions can make a low initial quote misleading.
Three project sizes show how installed totals can vary
| Project | Scope | Estimated total | Implied rate |
|---|---|---|---|
| Garden path | 120 sq ft, simple access, limited prep | $600-$1,200 | $5-$10/sq ft |
| Backyard patio | 300 sq ft, base and edging included | $1,500-$3,000 | $5-$10/sq ft |
| Large yard area | 700 sq ft, moderate grading and delivery | $3,500-$7,700 | $5-$11/sq ft |
These examples assume standard residential access and do not include major retaining walls or extensive drainage work. The rate can rise for a small path because setup costs are spread over fewer square feet. Compare total project prices alongside square footage, depth, and included preparation.
How to lower a stabilized DG estimate without cutting corners
Keep the design compact and limit curves, borders, and decorative transitions that require extra layout labor. If the site is sound, ask whether existing base material can be reused after inspection rather than replaced automatically. Handle simple vegetation removal or access clearing only when the contractor confirms it will not affect grade or drainage.
Request at least three itemized quotes using the same square footage, compacted depth, stabilizer specification, edging, and disposal scope. Scheduling outside peak landscaping periods may improve availability, though savings vary by market. Control the project scope and compare identical specifications before choosing on price. Avoid reducing base depth or skipping drainage measures just to reach a lower bid.
