Treated lumber prices vary by size, grade, and market conditions. This article breaks down typical costs for common sizes, explains what drives the price, and offers practical ways to budget accurately. The keyword price appears naturally to reflect buyers’ cost focus when budgeting for projects using treated lumber.
Assumptions: Midwest labor rates, standard preservative treatment, and typical residential construction access are considered.

Treated Lumber Price Ranges By Size And Grade
Prices differ by size, grade, and region. Typical total price per project often hinges on board count, lengths, and how many boards require premium grade or broader spacing. For residential projects, budgets commonly anchor on deck framing, fencing, or general framing needs.
| Size | Grade | Low per Board | Average per Board | High per Board | Typical Use |
|---|---|---|---|---|---|
| 2×4 | STK | $1.25 | $2.75 | $4.50 | Framing, blocking |
| 2×6 | STK | $1.80 | $3.60 | $5.90 | Fencing, light framing |
| 2×8 | STK | $2.80 | $6.00 | $9.50 | Deck framing |
| 2×10 | HT | $5.20 | $9.80 | $14.50 | Structural members |
| 2×12 | HT | $7.50 | $12.50 | $18.50 | Heavy framing |
Quotes typically itemize materials, labor, and delivery. Materials cover the boards themselves; Labor accounts for cutting, nailing, and waste handling; Delivery reflects freight or truck charges; additional line items may include waste disposal and fasteners. A sample breakdown shows common line items and ranges to expect in a realistic quote.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (lumber only) | $600 | $1,800 | $3,000 | Board count and grade depend on scope |
| Labor | $400 | $1,200 | $2,000 | Deck or framing work |
| Delivery | $50 | $150 | $450 | Distance from supplier |
| Fasteners | $25 | $60 | $100 | Deck screws, nails, anchors |
| Waste disposal | $20 | $60 | $150 | Scrap and offcuts |
| Total (example) | $1,095 | $3,270 | $5,700 | Assumes mid-range project |
Core drivers include board size and length, treatment level and preservative type, and regional freight costs. In many markets, 8 ft boards are cheaper per linear foot than 12 ft boards, but require more boards to cover the same area. Regional demand and supply shocks can swing prices by 10-25% between markets.
Prices per board can vary by region due to labor costs, shipping, and local availability. For example, coastal markets may see higher delivery fees, while inland regions with large lumber mills may have lower base prices. Expect 5-15% regional deltas on average, with larger ships and remote areas pushing higher costs.
| Region | Low | Average | High | Notes |
|---|---|---|---|---|
| Midwest urban | $2.60 | $4.50 | $6.80 | Strong volume, steady pricing |
| Northeast coastal | $3.00 | $5.20 | $7.90 | Higher delivery and demand |
| South rural | $2.20 | $3.90 | $6.20 | Lower freight, variable grades |
| West Coast | $3.10 | $5.60 | $8.20 | Logistics and rates fluctuate |
Deck projects, fencing installations, and structural framing have different cost profiles. Deck framing with 2×8 or 2×10 boards across 200 ft of joists adds material and labor complexity, while simple fence line uses shorter boards and fewer cuts. Understanding size and scope helps lock in realistic price ranges rather than broad estimates.
Labor costs scale with crew size and job duration. A typical small deck framing job might require a 2-person crew for 8-12 hours, while larger builds need 3-4 workers for multiple days. Labor rate ranges from $45-$75 per hour per worker, depending on region and contractor experience.
Prices can climb in spring and early summer when outdoor projects surge. Winter slowdowns can reduce availability and raise per-board pricing in some markets. Expect price upticks of 5-12% during peak demand months and potential discounts for off-season scheduling.
Choosing grade and size strategically can reduce overall spending. Opting for standard pressure-treated pine over higher-grade tropical selections and using shorter lengths with efficient layout can lower waste. Consider deck screws vs nails based on weather resistance and labor ease to cut total costs.
Typical totals encompass materials, labor, and delivery. Average overall project price often reflects deck framing or fencing scope, including fasteners and minor spoilage. Assumptions: standard 300- to 600-square-foot deck or perimeter fencing; mid-range grade; normal access to material yard.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $600 | $1,900 | $3,200 | Board count depends on area |
| Labor | $350 | $1,150 | $2,300 | Cutting, fasteners, assembly |
| Delivery | $40 | $150 | $350 | Distance from mill |
| Subtotal | $990 | $3,200 | $5,850 | Includes typical waste |
Four to six cost lines are common. Materials, Labor, Delivery/Disposal, and Fasteners form the core; Permits or Taxes may appear for larger projects. The table shows a practical example for a modest job.
| Cost Area | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (boards) | $600 | $1,900 | $3,000 | Standard boards |
| Labor | $350 | $1,150 | $2,300 | Framing work |
| Delivery/Disposal | $40 | $120 | $300 | Local haul |
| Fasteners | $25 | $60 | $100 | Screws and nails |
| Permits/Taxes | $0 | $60 | $300 | Local requirements |
Key variables include board length and quantity and treatment level (ACQ vs CCA). Another driver is local delivery distance which can shift total by 5-15% in many regions. Longer spans or specialty fasteners can push quotes higher.
Strategies include refining scope, timing purchases, and material substitutions. Order standard sizes in bulk when possible, compare quotes across sellers, and bundle delivery with other purchases to reduce trips. Consider repurposing existing framing where feasible to cut costs.
