Buyers typically pay a premium for treated lumber due to enhanced durability and rot resistance, while untreated wood remains cheaper but requires more maintenance or protective finishes. Main cost drivers include material grade, treatment type, dimensions, and regional pricing fluctuations. This guide presents clear cost ranges and practical pricing context for U.S. buyers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material (Lumber) | $1.20/board ft | $1.60/board ft | $2.20/board ft | Treated vs Untreated price gap varies by species and grade. |
| Treatment (if applicable) | $0.15–$0.50/bd ft | $0.25–$0.60/bd ft | $0.70–$1.20/bd ft | Includes barriers like pressure treatment or other preservatives. |
| Labor & Installation | $0.40–$1.20/board ft | $0.80–$1.60/board ft | $1.70–$2.60/board ft | Variation by crew skill and project complexity. |
| Delivery | $50–$150 | $90–$300 | $350–$700 | Distance and volume affect costs. |
| Waste & Offcuts | $5–$20 | $15–$60 | $60–$120 | Depends on project size and cut efficiency. |
| Permits/Fees | $0–$50 | $10–$150 | $200–$400 | Mostly for large framing or structural work. |
| Warranty | $0 | $0–$50 | $50–$150 | Limited warranties may add value modestly. |
| Taxes | Included in price | Included in price | Included in price | State and local rates apply. |

Overview Of Costs
Treated wood generally carries a higher upfront cost than untreated wood due to the preservation process and longer lifespan. The price gap depends on species, grade, and the chosen treatment method. For a typical project using common lumber grades, expect treated lumber to be approximately 20–60% higher per board foot than untreated equivalents, with the premium more pronounced in higher-grade or larger-dimension boards. Per-unit costs are often quoted as either dollars per board foot or dollars per linear foot, plus variable installation and delivery charges.
Cost Breakdown
Material costs dominate early budgeting, while labor and delivery become meaningful on mid- to large-scale projects. A breakdown captures materials, labor, delivery, and potential extras. The following table consolidates typical line items and相ires both totals and per-unit measures to help compare treated vs untreated scenarios.
| Column | Treated Wood | Untreated Wood |
|---|---|---|
| Materials | $2.00–$2.80/board ft | $1.30–$1.90/board ft |
| Labor | $0.80–$1.60/board ft | $0.40–$1.20/board ft |
| Delivery/Disposal | $60–$320 | $40–$180 |
| Permits | $0–$150 | $0–$100 |
| Warranty | $0–$100 | $0–$50 |
| Taxes | Varies by state | Varies by state |
Assumptions: project hip-to-shoulder framing, standard residential lumber, mid-range species, local delivery within 50 miles.
What Drives Price
Price is driven by wood species, grade, dimensions, and the chosen preservation method. For treated wood, the treatment type (CCA-free alternatives, water-based vs oil-based preservatives) and the thickness of surface coating affect both material cost and long-term maintenance needs. Regional demand, bulk purchasing, and seasonal supplier stock also influence quoted prices.
Ways To Save
Shop by project scope and blend product types to optimize budget. Adopting 2×4 or 2×6 standard sizing, ordering in bulk, and coordinating delivery timing with other projects can reduce waste and cut costs. Consider using untreated wood for non-structural elements or applying protective finishes to extend life without the treatment surcharge.
Regional Price Differences
Prices vary across regions due to supply chains and local demand. In urban markets, expect higher baseline material costs and delivery fees, while rural areas may offer lower rates but limited stock. A representative spread demonstrates roughly ±10–25% regional delta for both treated and untreated wood, with urban centers typically at the higher end of ranges and rural zones at the lower end.
Labor & Installation Time
Labor costs scale with project complexity and crew efficiency. Simple deck framing may require fewer hours, while multi-story or complex joint systems increase time and rate. Typical residential installations run from 10–12 hours for small jobs to 40–60 hours for larger builds, with labor rates of $40–$100 per hour depending on location and contractor expertise. Per-unit labor costs often track board footage and framing complexity.
Real-World Pricing Examples
Three scenario cards illustrate common budget ranges for Treated vs Untreated Wood.
Scenario A — Basic Budget (Small Deck)
Specifications: treated pine framing, standard 2×6, 8 ft spans, basic hardware. Labor hours: 14. Per-unit: $2.20/board ft materials, $0.90/board ft labor. Total: approximately $1,900–$2,600 depending on region and delivery.
Scenario B — Mid-Range Project (Platform Deck with Rail)
Specifications: treated lumber with mid-grade finish, 2×8 and 2×10, 12 ft spans, railing components. Labor hours: 28. Per-unit: $2.50–$3.00/board ft materials, $1.20–$1.60/board ft labor. Total: approximately $4,800–$6,200.
Scenario C — Premium Build (Non-Structural Use in Wet Area)
Specifications: higher-grade treated lumber, additional coatings, moisture barriers, 2×6 and 4×6 elements. Labor hours: 42. Per-unit: $3.20–$3.80/board ft materials, $1.40–$2.10/board ft labor. Total: approximately $9,000–$12,500.
Assumptions: region, specs, labor hours.
