The cost of lumber for a deck typically hinges on wood type, deck size, and delivery. This guide covers price ranges in USD, with clear low–average–high estimates to help with budgeting and planning for a deck project.
Assumptions: region, deck size, species, and installation options vary; prices reflect typical U.S. markets.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Lumber Materials (Decking Boards) | $1,000 | $2,800 | $7,000 | Includes common PT boards and mid-range hardwoods; per-linear-foot pricing varies by species. |
| Framing Lumber (Support Structure) | $800 | $2,000 | $4,500 | Includes 2×6 or 2×8 members; price depends on span and yard stock. |
| Fasteners & Hardware | $100 | $350 | $800 | Hardware, corrosion-resistant fasteners, post anchors, joist hangers. |
| Stain/Sealant | $50 | $180 | $450 | Protects wood and extends life; may be annual or biannual. |
| Delivery & Handling | $80 | $300 | $900 | Shipped or hauled to site; larger orders incur higher freight. |
| Contingency (Waste & Cutting) | $50 | $200 | $600 | Extra for off-cuts, misorders, and on-site adjustments. |
Overview Of Costs
Cost ranges blend total project pricing with per-unit estimates to reflect both material and handling needs. For decking, materials commonly fall in a broad spectrum: low-cost PT boards or pressure-treated pine start at about $1.20-$2.50 per linear foot, while mid-range composite and select hardwoods run higher. A typical backyard deck uses 200–600 square feet of decking, which translates to a material bill of roughly $1,000-$9,000 depending on wood choice and deck size. Per-square-foot figures help compare options: budget decks around $3-$8 per sq ft, with premium woods and composites climbing to $12-$25+ per sq ft including basic framing. Assumptions: regional pricing, standard joist spans, and average overhead.
Cost Breakdown
Material costs dominate the spread for lumber-based decks, with framing and fasteners forming a solid secondary driver. A practical breakdown for a mid-size deck shows decking boards at 50–70% of materials costs, framing at 25–35%, and hardware, stains, and delivery making up the remainder. For concrete or elevated installations, expect higher framing costs and delivery surcharges. On a per-unit basis, decking boards commonly price by linear foot or square foot, while framing lumber is priced per board or per foot of span. data-formula=”lumber_cost + framing_cost”>
What Drives Price
Key price drivers include wood species, board width and thickness, and deck size. Treated pine is the lowest-cost option, while exotic hardwoods like ipe or tigerwood command the high end. Narrow boards save money but may require more fasteners and more frequent maintenance. Deck size amplifies every line item, particularly lumber and delivery. For framing, the span and layout determine the amount of material, with longer spans needing more joists and larger footings. Regional supply conditions and seasonal demand also affect both material and delivery charges.
Ways To Save
Smart choices can trim upfront lumber costs without sacrificing durability. Consider selecting standard-width boards (4–6 inches) instead of premium extra-wide stock, and balance between hardwood and treated pine based on budget and climate. Bulk purchasing from local suppliers can reduce per-foot costs, while planning for off-peak delivery windows may lower freight. Reusing off-cuts for trim pieces or small repairs reduces waste. If installation is DIY, factor in tool rental and your time; professional installation adds labor costs but improves finish quality and warranty coverage.
Regional Price Differences
Prices vary across urban, suburban, and rural markets due to freight, availability, and labor. In the Northeast and West Coast, high demand and shipping can push lumber costs higher by about 5–15% versus national averages. Suburban markets often see moderate ranges, while rural areas may offer lower base prices but higher delivery fees. For a 300–350 sq ft deck, this could shift material costs by several hundred dollars depending on supplier mix and delivery access. Regional variance is amplified when choosing exotic species or premium composites.
Labor & Installation Time
Labor costs depend on crew size, experience, and deck height. A typical two-person crew can complete a basic framed deck in 2–4 days, assuming dry weather and accessible site work. Labor rates commonly range from $40–$75 per hour per worker, with higher-end specialists charging $80–$120+. For larger or multi-level decks, plan for 40–120 hours of labor or more. If you hire a contractor, expect a bundled estimate that includes material procurement, site prep, and finishing work, though some firms itemize materials separately to show cost transparency.

Additional & Hidden Costs
Expect costs beyond lumber to influence the final price. Soil preparation, permits, or inspections can add $200–$1,200 depending on jurisdiction and deck size. Gate or railing upgrades, lighting, and built-in planters increase material and labor. Waste management, rental tools, and contingency allowances typically add 5–15% to the overall project budget. If trees or utilities require on-site adjustments, costs rise accordingly. Schedule buffers for weather delays to avoid expedited delivery surcharges.
