Buyers commonly face a cost decision between plastic lumber and traditional wood, weighing upfront price against long-term value. This article presents concrete price ranges in USD, breaks down major cost drivers, and highlights how materials influence the total project equity. The focus is on actual price ranges you can expect for common applications such as decking, fencing, and outdoor structures.
Assumptions: Midwest labor rates, standard 2×6 or 5/4 decking boards, normal access, and typical consumer-grade plastics with reinforced polymers used for outdoor lumber.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Decking installed price (Plastic Lumber) | $6.00 per sq ft | $9.50 per sq ft | $14.00 per sq ft | Includes boards, fasteners, basic framing, and labor |
| Decking installed price (Wood) | $3.00 per sq ft | $5.50 per sq ft | $8.50 per sq ft | Pressure-treated to hardwood varies by species |
| Per-linear-foot board cost (Plastic Lumber) | $2.50 | $3.75 | $6.00 | Face-up costs vary by profile |
| Per-linear-foot board cost (Wood) | $1.50 | $2.75 | $4.50 | Species and grade drive price |
| Delivery/Haul-away | $100 | $350 | $800 | Material size and distance matter |
| Maintenance (annual, plastic) | $0.10 per sq ft | $0.25 per sq ft | $0.50 per sq ft | Cleaning, sealant if needed |
| Maintenance (annual, wood) | $0.15 per sq ft | $0.40 per sq ft | $0.75 per sq ft | Stain/seal, replacing damaged boards |
Installed Decking Costs by Material: Plastic Lumber Versus Wood
Plastic lumber typically costs more upfront per square foot than wood, but it can reduce ongoing maintenance expenses. In standard deck projects, plastic decking ranges from $6.00 to $14.00 per sq ft installed, with midpoints near $9.50 per sq ft. Wood decking (pressure-treated or basic hardwood) commonly runs from $3.00 to $8.50 per sq ft installed, averaging around $5.50 per sq ft. The cost gap widens when premium plastics with colorants or reinforced polymers are used.
Material choice also affects adjacent components. Plastic lumber often requires specialized fasteners and hidden-clip systems, which can add $0.50 to $1.50 per sq ft to the installed price. Wood projects may need less expensive fasteners but can incur higher sealant or stain costs over time.
Per-Unit Pricing: By Square Foot and Linear Foot
For deck boards, plastic lumber can be priced around $2.50 to $6.00 per linear foot depending on profile and thickness, while wood boards typically run $1.50 to $4.50 per linear foot. When calculating, include hidden fasteners and joist prep as part of the per-foot cost.
Smaller projects such as railing or lattice may show a different ratio, with plastic railing components costing more per linear foot than wood equivalents due to polymer formulations and UV stabilization.
Major Cost Components in a Plastic Lumber vs Wood Project
Project quotes typically break into four to six parts: Materials, Labor, Delivery/Disposal, Fasteners/Hardware, and Preparation. Below is a compact view of common cost shares for decking installations.
| Component | Plastic Lumber Project | Wood Project |
|---|---|---|
| Materials | $4.50–$9.50 per sq ft | $2.50–$6.50 per sq ft |
| Labor | $2.00–$4.50 per sq ft | $2.50–$4.00 per sq ft |
| Fasteners/Hardware | $0.50–$1.50 per sq ft | $0.25–$0.75 per sq ft |
| Delivery/Disposal | $100–$350 | $100–$350 |
| Preparation/Inspection | $0.50–$1.50 per sq ft | $0.50–$1.50 per sq ft |
| Total (installed) | $6.00–$14.00 per sq ft | $3.00–$8.50 per sq ft |
Key Variables That Shift the Final Quote
Material profile and cross-section are major levers. If plastic lumber uses high-density polymer with UV stabilizers, expect the higher end of the range. For wood, species grade (pine, cedar, composite hardwood) drives the spread most. A longer run, steeper slope, or raised-bed framing adds hours and increases per-square-foot costs. Labor rates rise with city density and installer experience, and regional freight costs affect material pricing.
Regional Price Variations Across U.S. Markets
Prices reflect local labor, supply chains, and permit practices. Coastal markets tend to see higher installed prices than rural areas, with typical regional deltas of 5% to 20% on both plastic and wood decking. In the Southeast, consumer-grade plastics may be closer to the lower end of the range; in the Northeast, premium plastic profiles can push costs higher due to shipping and limited suppliers.
Maintenance and Lifecycle Costs Compared
Plastic lumber generally avoids regular staining and sealing, reducing annual upkeep costs. Typical annual maintenance for plastic is $0.10 to $0.50 per sq ft, while wood maintenance runs $0.15 to $0.75 per sq ft. Over a 20-year horizon, plastic may present lower cumulative maintenance but a higher initial outlay, affecting the total cost of ownership.
Practical Ways To Reduce Total Project Cost
Scope control is the strongest lever. Consider standard profiles and sizes, minimize custom cuts, bundle delivery with other materials, and avoid premium finishes unless needed. Sealing or staining wood less frequently by choosing higher-grade finishes can cut ongoing costs. If replacement is uncertain, compare the lifetime maintenance gap between wood and plastic to the upfront price delta.
Alternative Materials And Substitutes To Consider
Composite wood, PVC decking, and high-density polyethylene blends are common substitutes. Compared with standard wood, composites often offer similar installation costs but with different maintenance and warranty terms. Per-unit costs typically fall within the plastic-versus-wood ranges noted earlier, but warranties and warranties length can shift long-run value.
What to Ask When Getting Quotes
Ask for a breakdown of Materials, Labor, and Delivery. Request per-square-foot pricing with and without fasteners, and confirm whether the quote includes removal of old decking. Clarify whether the estimate assumes standard joists and railings or requires additional framing work. A transparent quote helps compare plastic lumber and wood on a like-for-like basis.
