When choosing between a new concrete slab and a wooden or composite deck, buyers typically see price ranges driven by area, material type, and installation complexity. This guide compares cost, price ranges, and common outlays to help budgeting decisions.
Cost considerations include material choice, project size, and local labor rates, which together shape the total price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Concrete slab (all-in) | $4.50/sq ft | $6.50/sq ft | $9.50/sq ft | |
| Decking (wood) | $12,000 | $22,000 | $38,000 | |
| Decking (composite) | $14,000 | $28,000 | $50,000 | |
| Seating/railings (per linear ft) | $20 | $60 | $150 | |
| Perimeter concrete edge/curb | $2,000 | $5,000 | $12,000 |
Overview Of Costs
Concrete work typically shows a lower upfront cost per square foot for basic slabs than a full deck, but a deck can add long-term value and outdoor living space. The main cost drivers include area, thickness for concrete, material type for decking, and labor intensity. Assumptions: residential backyard, standard weather, mid-range local labor rates.
Cost Breakdown
The following table outlines how costs usually break down for concrete vs deck projects, with typical share of the total and common line items. Assumptions: 1,000 sq ft patio or deck footprint, standard soil, no major site prep.
| Costs | Concrete Slab | Deck (Wood) | Deck (Composite) | Notes |
|---|---|---|---|---|
| Materials | Materials + reinforcement | Lumber or boards + fasteners | Composite boards + clips | |
| Labor | Excavation, forms, pour, finish | Framing, joists, planks, railing | ||
| Equipment | Mixer, screed, compactor | Saw, nailers, lifts | ||
| Permits | Permits often required | Permits typically required | ||
| Delivery/Disposal | Concrete delivery, waste | Delivery of lumber/materials | ||
| Warranty | Material and workmanship | Material warranty varies by product | ||
| Overhead & Contingency | ~10–15% | ~10–15% | ||
| Taxes | Sales tax where applicable | Sales tax where applicable |
What Drives Price
Project size, thickness or species, and installation time are the top price drivers for both concrete and decking. For concrete, slab thickness (often 4–6 inches, sometimes thicker for vehicles) and reinforcement (rebar or mesh) affect cost. For decking, species like pressure-treated wood or cedar, and the choice of railing height and infill impact pricing significantly. Concrete also varies with per-square-foot labor and regional material costs.
Factors That Affect Price
Regional differences, seasonality, and site accessibility can shift totals by notable margins. Labor rates are higher in urban markets versus rural areas, and extreme climates may require additional curing or moisture protection. A sloped site or hard-to-reach pour can add equipment time and costs.
Ways To Save
Cost-saving tips include combining projects, selecting mid-range materials, and planning for proper drainage to avoid future repairs. Consider a simple concrete slab if you want minimal maintenance, or choose a budget-friendly wood deck with basic railing to balance upfront price and longevity.
Regional Price Differences
Prices shift across the U.S. due to labor markets and material sourcing. In the Northeast, concrete pours may run 5–10% higher than the national average due to stricter codes and higher labor costs. The Midwest often sits near the national average, while the South can be 5–12% lower because of milder winters and lower labor rates. Regional differences mean a 1,000 sq ft concrete slab could range from roughly $4,500 to $12,000 depending on location and site specifics.
Labor & Installation Time
Concrete slabs require fewer crew hours per square foot than a multi-section deck but may involve longer curing times, extending project duration. Basic pours for 1,000 sq ft typically require 2–4 days of crew time on site, plus curing, while wood decks may need 3–6 days for framing, decking, and railing installation. Assumptions: crew of 3–5 workers, standard weather.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes for concrete vs deck projects in common settings. Assumptions: region, specs, labor hours.
Basic Scenario
Concrete: 1,000 sq ft slab at 4 inches thick with simple rebar: $4,500–$6,500. Deck: Pressure-treated wood with basic railing, 1,000 sq ft area: $12,000–$18,000. Total combines materials and labor with minimal extras.
Mid-Range Scenario
Concrete: 1,200 sq ft slab, 5 inches thick, fiber reinforcement: $7,000–$9,500. Deck: Composite boards, mid-range railing, 1,000 sq ft: $20,000–$32,000. Adds some edging, drainage, and a small curing area.
Premium Scenario
Concrete: 1,500 sq ft stamped/colored finish, 6 inches thick: $15,000–$25,000. Deck: Cedar or high-end composite with upgraded railing and lighting: $35,000–$60,000. Includes decorative details and site prep.
Assumptions: region, specs, labor hours.
