Understanding Redwood Deck Lumber
Redwood is prized for its natural resistance to decay, insects, and warping, making it one of the top choices for outdoor decking. Its unique cell structure enables it to resist moisture penetration better than most softwoods. Sourced primarily from Northern California, redwood decking is available in several grades, each offering a distinct balance of aesthetics and structural integrity.
Redwood’s color spectrum—ranging from light pinks to deep reddish-browns—adds visual warmth to outdoor living spaces. Its natural oils help preserve the material, giving it a longer life with minimal maintenance compared to pressure-treated pine.
Factors That Impact Redwood Deck Lumber Prices
Several interconnected factors influence redwood lumber prices in 2025. Being aware of these helps you strategize your purchase and stay within budget:
- Grade of Lumber: Higher grades like Clear All Heart command premium prices due to minimal knots and superior aesthetics.
- Board Size & Thickness: Larger, wider, or thicker boards cost more per board foot.
- Source & Sustainability: FSC-certified or old-growth redwood may cost more but offers sustainability benefits.
- Market Supply: Regional supply fluctuations, wildfires, and lumber mill output can impact pricing.
- Retailer Markup: Stores like www.menards.com and www.lowes.com have different price structures based on supply chain costs.
- Delivery Costs: Bulk orders may come with discounts but require factoring in substantial shipping fees, especially from specialty suppliers like www.thelumberbaron.com.
- Seasonal Demand: Lumber prices often rise in spring and summer due to increased building activity.

Cost Comparison: Redwood vs. Alternative Decking Materials
Understanding redwood’s competitive pricing lets you evaluate it against:
| Material | Avg. Material Cost/sq. ft. | Durability (years) | Maintenance | Appearance |
|---|---|---|---|---|
| Redwood | $5 – $35 | 20-30+ | Moderate | Natural, warm |
| Pressure-Treated Pine | $2 – $7 | 10-15 | High | Plain, may splinter |
| Composite | $7 – $15 | 25-50 | Low | Faux wood, uniform |
| Cedar | $5 – $15 | 15-25 | Moderate | Reddish, soft grain |
| Tropical Hardwoods | $8 – $20 | 30-50+ | Low to moderate | Exotic, dense |
Redwood sits at the intersection of aesthetics and value—more luxurious than pine, less costly than imported hardwoods, and with greater authenticity than composites.
How Redwood Lumber Is Sold and Measured
Redwood is typically sold:
- By Board Foot: Common for rough or dimensional lumber
- By Linear Foot: Many retailers price decking boards by length
- By Unit/Pack: Bulk pricing for contractors and large projects
A standard decking board is usually 2×6 inches in nominal size (actual dimension 1.5″x5.5″). Calculation of required lumber involves deck size, board width, and spacing (often 1/8″-1/4″ gap for drainage).
Example: For a 320 sq. ft. deck, expect material costs (boards only) from $1,600 (low grade) to $11,000 (Clear All Heart).
The Complete Redwood Decking Project Cost
A typical redwood decking project includes:
- Material Selection: Boards, joists, posts, fasteners, stain/sealer.
- Site Prep: Clearing, leveling, and foundation (concrete piers or footings).
- Installation: Labor for framing, decking, railing, and stairs.
- Finishing: Sanding, sealing, and cleanup.
- Permits/Design: Local codes may require professional plans.
Industry estimates (planner5d.com, www.homeadvisor.com):
- Material Only (Deck Boards): $500 – $3,500 for 100 sq. ft.
- Labor & Install: $15 – $35/sq. ft. depending on complexity.
- Total Project: $5,000 – $17,000 for a 320 sq. ft. deck.
Money-Saving Tips When Buying Redwood
- Compare Quotes: Solicit deals from www.menards.com, www.lowes.com, and local yards.
- Opt for Heartwood Construction Grade: A balance of cost and longevity.
- Buy in Off-Season: Late summer or fall purchases can save 10-15%.
- Consider Shorter Lengths: Slightly lower per-foot cost, less waste.
- Bulk Purchase: Contractors or large DIY projects can negotiate better pricing.
- Plan Efficient Layouts: Minimize board cuts to maximize yield from each board.
Maintenance and Longevity: Getting the Most from Redwood
Redwood’s longevity is legendary, but proper care doubles its life:
- Annual Sealing: Use a penetrating oil-based deck sealer to lock in color and repel water.
- Gentle Cleaning: Sweep debris, use mild soap and water for spring cleanings.
- Refinishing: Every 2-5 years, sand and restore high-traffic areas.
- Prompt Repairs: Replace damaged boards to avoid structural decay.
Heartwood grades can last 30 years or more with diligent maintenance, while sapwood or lower grades may need attention in as little as 10-15 years.
Professional vs. DIY Installation
Professional Installation
- Advantages: Warranty, code compliance, higher resale value, proper permits.
- Typical Costs: $25 – $40 per sq. ft. including labor (www.homeadvisor.com, www.angi.com).
DIY Installation
- Advantages: Cost savings, project customization.
- Typical Costs: Materials only, but factor in tool rental, fasteners, and additional time.
- Considerations: Knowledge of carpentry, local codes, and structural safety is essential.
