| 4×4 treated posts | $6.00 | $8.50 | $12.00 | Common rough-cut stock |
| 6×6 treated posts | $12.00 | $16.00 | $24.00 | Heavier load-bearing use |
| 2×6 treated boards (8 ft) | $6.50 | $9.50 | $13.50 | Standard fence/deck boards |
| 2×8 treated boards (12 ft) | $9.00 | $12.50 | $18.00 | Longer spans, fewer joints |
| Delivery (within 20 miles) | $45 | $85 | $150 | Flat fee or tiered |
| Knots, warps, defect allowance | Included | Included | Extra | Quality adjustments |
Typical Price Range for CCA Treated Lumber by Dimension
Role A: Buyers usually pay for dimension-specific lumber with price influenced by length, thickness, and treatment used. For standard residential projects, 8 ft and 10 ft boards in common dimensions carry the most volume. Assumptions: Midwest/Jersey region, standard Kiln-dried stock, normal access, typical contractor markup.
Typical totals for small projects (about 150–300 board feet) often fall in the $350–$900 range, depending on dimension mix and quantity. For larger decks or fences using multiple dimensions, expect $1,200–$3,000 as a typical project subtotal before labor and delivery. Per-unit pricing commonly appears as $4–$12 per linear foot for boards and $6–$20 per linear foot for posts, depending on size and length.
Cost Components in a CCA Treated Timber Quote
Role B: A standard quote breaks into major parts to help buyers compare quotes. The following table shows typical components and how they affect the total.
| Component | Typical Range | Impact on Total | Notes |
|---|---|---|---|
| Materials | $4–$12 per linear ft (boards); $6–$24 per post | Major | Depends on dimension and stock quality |
| Labor | $40–$75 per hour | Moderate to High | Installation, cutting, and fasteners included |
| Delivery/Disposal | $45–$150 | Low to Moderate | Distance-based charges may apply |
| Permits/Fees | $0–$100 | Low | Typically none for simple residential use |
| Hardware/Fasteners | $0.50–$2 per ft of board | Low | Galvanized or coated recommended |
| Warranty/Quality Assurance | $0–$40 | Low to Moderate | Material defect coverage varies |
How Size, Grade, and Region Shift the Price
Role C: The final price hinges on several thresholds. Project size (board feet), region, and stock grade have measurable effects. For example, coastal regions often see a 5–15% premium versus inland markets due to transport costs and demand. Projects using higher grades of lumber or longer lengths push per-foot costs upward by 20–40% in many regions. Additional scale, such as a deck frame of 1,000+ linear feet, can unlock bulk discounts but may also trigger higher delivery charges if multiple shipments are needed. Assumptions: single-site residential project, standard is treated pine or equivalent.
Labor and Delivery: What Affects Onsite Costs
Role D: Onsite labor and delivery timing can shift costs meaningfully. Labor for framing and fastening typically runs $40–$75 per hour per crew, with 2–4 workers common on a deck or fence build. Delivery charges depend on distance and driver availability, ranging from $45 to $150. Scheduling during peak season (spring weekends) can add a small premium or require extended lead time. Assumptions: standard access, single delivery, no site complications.
Regional Price Differences Across U.S. Markets
Regional deltas matter for CCA treated timber. Western markets may price boards 5–12% higher due to transport costs, while some Southern markets run closer to the national average. Labor costs also vary by region, potentially widening the total project price by 8–15% when comparing a midwest crew to a coastal crew. Always compare quotes with the same dimensions and lengths to ensure apples-to-apples pricing. Assumptions: typical residential deck/fence scope, mid-range material quality.
What Can Cut Your CCA Treated Timber Bill
Role D: Controlling scope reduces price without sacrificing essential value. Consider batching projects to use common dimensions, choosing standard lengths (8, 10, 12 ft) over custom cuts, and avoiding premium stock. If structural requirements permit, substitute lower-grade stock with treated alternatives that meet code but reduce cost. Delaying nonessential upgrades, coordinating delivery with other purchases, and verifying waste allowances can trim costs. Assumptions: project allows standard sizes and no specialty fasteners.
Per-Unit Pricing Details for Common Dimensions
Unit pricing helps with quick budgeting. Typical ranges include $4–$12 per linear foot for boards and $6–$24 per post, depending on dimension and region. For example, a 12 ft 2×6 board might cost around $9–$14, while a 8 ft 6×6 post could be $14–$22. Per-unit pricing is most useful when planning fence lines, deck frames, or supports. Assumptions: standard seasoning and moisture content, treated with a common preservative.
Delivery, Waste Handling, and Add-Ons
Delivery fees, onsite cleanup, and waste handling can add $40–$120 to a project. If disposal involves cutting scrap or removing old posts, include a disposal charge or separate labor for cleanup. Some suppliers include small protective end caps or fasteners in the quote; others itemize them as add-ons. Assumptions: no bulky debris beyond typical framing waste.
Unit and Scenario Pricing by Deck or Fence Scope
Role A: For a typical residential fence around 200–400 linear feet, expect a subtotal in the $1,000–$3,000 range for materials alone, depending on height, post spacing, and board choice. A wooden deck frame of 300–500 square feet commonly lands in the $2,000–$6,000 range for materials, with labor and hardware driving the total higher. Per-unit totals vary by length and dimension, so build both a per-foot and per-area budget to compare bids. Assumptions: standard backyard usage, 16 ft post spacing, no exotic species.
