Homeowners typically spend on materials, shipping, and installation when choosing merbau decking. Main cost drivers include board grade, thickness, total area, labor rates, and regional material availability. This guide presents practical price ranges in USD to help budgeting and compare options.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (Merbau boards) | $5.00/sq ft | $8.50/sq ft | $12.50/sq ft | |
| Labor & Installation | $7.50/sq ft | $13.00/sq ft | $20.00/sq ft | |
| Fasteners & Accessories | $0.50/sq ft | $1.50/sq ft | $3.00/sq ft | |
| Delivery/Hauling | $0.40/sq ft | $0.90/sq ft | $1.80/sq ft | |
| Total Installed (approx.) | $13.00/sq ft | $23.00/sq ft | $37.00/sq ft |
Assumptions: region, project size, board grade, and labor rates vary; prices reflect typical U.S. jobs with standard 0.75–1 inch thick merbau boards and basic substructure.
Overview Of Costs
Typical project ranges for merbau decking reflect both materials and installation. For a 250–500 square foot deck, expect the installed price to fall in the $6,500–$18,500 band, depending on board thickness, spacing, and labor rates. For larger projects, per-square-foot costs may decline slightly due to bulk handling, but added area increases total labor and delivery fees. Per-unit pricing helps estimate costs: merbau boards commonly run $6–$12 per square foot for materials, with installation often $8–$20 per square foot.
Specific price ranges include: Materials around $5–$12 per sq ft; installation $7.50–$20 per sq ft; total installed $13–$37 per sq ft, assuming standard 1″ merbau boards and basic fascia and trim. Variations arise from board grade, thickness, linear footage, and site accessibility.
Cost Breakdown
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (Merbau boards) | $5.00/sq ft | $8.50/sq ft | $12.50/sq ft | Includes basic grade and standard 1″ boards |
| Labor | $7.50/sq ft | $13.00/sq ft | $20.00/sq ft | Includes framing, installation, and fastening |
| Accessories | $0.50/sq ft | $1.50/sq ft | $3.00/sq ft | Fasteners, clips, spacers |
| Delivery | $0.40/sq ft | $0.90/sq ft | $1.80/sq ft | Shipping to site, handling |
| Permits/Fees | $0.00 | $0.75/sq ft | $2.00/sq ft | Depends on locality |
| Subtotal | $13.40/sq ft | $24.15/sq ft | $39.30/sq ft |
Assumptions: single-story installation, standard ground-level deck, basic underlayment, and no custom railings.
What Drives Price
Key cost drivers include board grade and thickness, with premium merbau grades costing more per linear foot and thicker boards increasing material weight and labor time. For example, choosing 5/4″ (1″) vs 2×6 boards can shift material costs by several dollars per square foot and extend installation time. Labor rates vary by region and crew experience, while delivery costs rise with distance from supplier and project site accessibility.
Other notable drivers are layout complexity, cutouts for steps or curves, and the required underlayment or vapor barrier. In drought-prone areas, additional sealing or maintenance steps can add to the long-term cost. Permits or local code requirements may add fees, especially for elevated structures or projects in jurisdictions with strict building standards.
Regional Price Differences
Prices vary by region, with the Northeast and West Coast often facing higher material and labor rates than the Midwest or South. A typical regional delta is ±10–25% depending on demand, shipping, and local competition. In urban markets, expect higher delivery fees and faster labor billing, while rural areas may see longer lead times but slightly lower hourly rates.
Assumptions: three representative regions used for comparison; actual regional variation may differ by supplier and contractor.
Labor & Installation Time
Installation time scales with deck size and complexity. A simple rectangular 300–350 sq ft deck can take 2–3 days for a small crew, while complex layouts with steps or curves may require 4–6 days. Labor costs factor in crew size, travel time, and setup. Typical crews include two to four workers for noncomposite hardwood decking.
Assumptions: standard joists, basic railing, and no special finishing beyond basic sealing.
Additional & Hidden Costs
Hidden costs often come from underlayment, flashing, and site prep. Concrete or soil prep, drainage modifications, or staining and sealing can add $1–$3 per sq ft post-install. If the project requires a crane or special equipment for elevated installations, expect higher charges. Unexpected weather-related delays can also push labor bills higher.
Assumptions: no skylights or embedded lighting; standard weather window.
