Homeowners typically pay for 20 ft composite deck boards based on length, color, and profile. The cost to buy 20 ft boards hinges on board width, core material, and the finish. This article breaks down the price range and factors so buyers can plan a budget for a standard back deck made with 20 ft composite planks.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 20 ft composite deck board price per board | $50 | $90 | $130 | Assumes common consumer-grade profiles |
| Price per linear foot (board width typical) | $2.50 | $4.50 | $6.50 | Width affects per-foot cost |
| Estimated total board cost for a 300 sq ft deck (boards only) | $1,350 | $2,700 | $4,350 | assumes 12–14 boards total, varies by width |
| Delivery/Tax/Fees | $0 | $150 | $350 | Region and retailer dependent |
Assumptions: Midwest, standard color, no waste, consumer-grade hidden-fastener system, normal access.
20 Ft Composite Deck Board Price by Brand and Type
Prices differ by material core and profile. Solid-core boards with capped polymer surfaces cost more than basic, uncapped cores. Typical range for a single 20 ft board is $50–$130, while premium lines can exceed $150 per board depending on color, embossing, and warranty length. A practical expectation is $90 per board on average, with seasonal promotions occasionally lowering costs.
Major Cost Components in a 20 Ft Deck Board Purchase
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $2.50/ft | $4.50/ft | $6.50/ft | Includes board core and cap layer |
| Labor for cutting and fitting | $1.00/ft | $2.00/ft | $3.50/ft | Assumes basic install and no custom milling |
| Hidden fasteners or edge trim | $0.50/ft | $1.25/ft | $2.00/ft | Per board if used |
| Delivery/Logistics | $0 | $60 | $180 | Distance-based |
| Waste/Offcuts | 5% | 10% | 15% | Based on layout efficiency |
| Taxes/Fees | $0 | $20 | $60 | Varies by state |
How Size, Color, and Profile Drive 20 Ft Board Pricing
Board width and profile influence cost. A 5.0–5.5 inch wide board costs more per linear foot than narrow options, and thicker corrugated or hollow-core profiles impact price as well. Color and embossing add small surcharges that compound across many boards, while longer warranty options push the price higher.
Regional Variations in Composite Deck Board Prices
Coastal markets and urban areas tend to have higher pricing due to freight and demand. Midwest and rural markets often see lower per-board prices, but shipping charges can narrow the gap. Typical regional delta is about 5–20% between low-cost inland regions and high-cost metropolitan zones for the same board model.
Labor and Installation Fees When Using 20 Ft Boards
Labor for installation is commonly charged per square foot or per board, with hourly rates ranging from $60 to $95 in most regions. For 20 ft boards, expect crew time to scale with deck size and joist spacing. Assume 6–9 hours for a small 150–250 sq ft project if boards are pre-cut and uninstalling old decking isn’t required.
Alternatives to 20 Ft Boards: Shorter Lengths or Transfers to Other Materials
Choosing 12 or 16 ft boards can reduce waste, expedite cutting, and lower labor costs. Some projects mix 20 ft boards in high-visibility runs with shorter lengths for ends. Substituting a premium product for a budget line can also shift the overall price picture. Mixing lengths can reduce total waste by 5–15%.
Ways to Reduce 20 Ft Board Costs Without Sacrificing Quality
Strategies include selecting standard colors, avoiding embossed textures, ordering in bulk, and timing purchases during promotions. Ensure accurate square footage estimates to minimize waste. Buy material for exact layout and opt for local delivery when possible to trim shipping.
Practical quote snapshot examples
The following rough quotes illustrate realistic ranges for a 250–300 sq ft deck using 20 ft composite boards. These examples assume a mid-range profile and standard hidden fasteners, with typical labor rates in a suburban market.
| Scenario | Boards Needed | Total Board Cost | Labor | Delivery | Estimated Total |
|---|---|---|---|---|---|
| Single 20 ft board, basic profile | 14–16 | $700–$1,400 | $300–$700 | $60–$150 | $1,060–$2,250 |
