Best Wood for Outdoor Deck: Cedar, Redwood, Ipe, and More

Choosing the best wood for outdoor deck construction is one of the most consequential decisions you will make during a deck build. The wrong species rots in five years. The right one can last three decades with minimal upkeep. Each wood species brings different strengths in durability, appearance, workability, and cost, so the choice comes down to your climate, budget, and how much maintenance you are willing to handle.

Pressure-Treated Pine: The Budget Standard

Pressure-treated southern yellow pine dominates the residential deck market, accounting for roughly 75% of all wood decks built in the US. Lumber yards stock it in every common dimension, and it costs between $1.50 and $3.00 per linear foot for standard 5/4×6 decking boards. The treatment process forces chemical preservatives deep into the wood fibers, giving it solid resistance against rot, fungal decay, and termite damage.

The tradeoff is appearance and maintenance. Pressure-treated pine tends to warp, crack, and splinter as it dries, especially if installed before the wood has had time to acclimate. You will need to stain or seal it within the first year and again every two to three years to maintain its appearance. The greenish tint fades to a silvery gray if left untreated. For budget-conscious projects where you plan to stain anyway, it remains hard to beat on value.

Western Red Cedar: Natural Beauty and Decay Resistance

Cedar has been a favorite decking wood for generations, and for good reason. Western red cedar contains natural oils called thujaplicins that resist rot, insects, and moisture without chemical treatment. It machines cleanly, accepts stain well, and has a warm reddish-brown tone straight off the saw. Expect to pay $3.50 to $6.00 per linear foot for clear or select grades.

Durability is moderate compared to tropical hardwoods. In ground-contact applications, untreated cedar lasts 15 to 20 years in dry climates but may deteriorate faster in the Southeast or Pacific Northwest where moisture is relentless. A quality penetrating oil applied every two years keeps the color vibrant and extends the lifespan significantly. Cedar is also about 50% lighter than most hardwoods, making it easier to handle during installation.

Redwood: Premium Softwood With Rich Color

California redwood offers the best natural decay resistance of any domestic softwood. Heartwood grades, labeled “Construction Heart” or “All Heart,” contain high concentrations of tannins that repel insects and resist fungal growth. The deep reddish hue is arguably the most attractive of any decking wood, aging gracefully to a silver patina if left unfinished.

Availability is the main limitation. Redwood supply has tightened considerably, pushing prices to $5.00 to $9.00 per linear foot depending on grade and region. Most of the premium heartwood comes from sustainably managed forests, but stock can be inconsistent outside the West Coast. If you live in California, Oregon, or Washington, redwood is worth serious consideration. Elsewhere, the shipping cost may push the total budget into tropical hardwood territory.

Ipe: The Gold Standard in Hardwood Decking

Ipe (pronounced “ee-pay”) is a Brazilian hardwood with a Janka hardness rating of 3,680, making it roughly three times harder than red oak. It resists rot, insects, mold, and even fire with a Class A flame-spread rating. An ipe deck installed properly can last 40 to 75 years, outlasting most of the houses it is attached to.

That performance comes at a premium. Ipe decking runs $4.50 to $8.00 per linear foot for materials, and the extreme density makes it harder to work with. You need carbide-tipped saw blades, and pre-drilling every screw hole is mandatory to prevent splitting. Many contractors charge 20% to 30% more for labor on ipe projects. The wood weathers to a silver-gray if left untreated, or you can maintain the rich brown color with an annual application of ipe oil, which costs around $50 to $70 per gallon.

Garapa and Tigerwood: Mid-Range Tropical Options

Not every tropical hardwood demands ipe-level pricing. Garapa, sometimes marketed as Brazilian ash, offers a Janka rating of 1,210 and a warm golden-yellow color. It resists decay and insects well, lasts 20 to 30 years, and costs $3.00 to $5.50 per linear foot. Tigerwood (also called goncalo alves) features dramatic orange and brown striping with a Janka rating around 1,850.

Both species are easier to machine than ipe, though pre-drilling is still recommended. Garapa is the lighter of the two, making it a strong alternative for homeowners who want tropical hardwood longevity without the extreme weight and workability challenges. Both species are available through specialty lumber suppliers and many online decking retailers.

White Oak: A Domestic Hardwood Alternative

White oak is gaining traction as a domestic hardwood decking option with legitimate rot resistance. Its tyloses, cellular structures that block moisture penetration, give it natural durability comparable to cedar. The Janka hardness of 1,360 puts it well above any softwood, and the grain pattern provides a clean, classic look. Pricing falls between $4.00 and $7.00 per linear foot for clear boards.

White oak is heavier than cedar or pine, so framing must be adequate, but it is far more manageable than ipe. It takes stain beautifully and can be sourced from domestic mills in the eastern United States. The main drawback is that it is not as widely stocked as other decking species, so lead times can run two to four weeks from specialty suppliers.

How to Choose the Right Wood for Your Climate

Climate should drive your species selection more than aesthetics. In hot, humid regions like the Gulf Coast or Florida, tropical hardwoods and pressure-treated pine outperform cedar and redwood, which can struggle with persistent moisture and mold pressure. In the arid Southwest, nearly any species holds up well, and cedar’s natural beauty shines without the constant moisture threat.

• Northern climates (freeze-thaw cycles): Ipe, garapa, or pressure-treated pine handle temperature extremes well. Avoid species prone to checking.
• Southeast and Gulf Coast (high humidity): Ipe or pressure-treated pine. Cedar needs aggressive maintenance in these conditions.
• Pacific Northwest (heavy rain): Cedar and redwood perform well here as they evolved in similar conditions. Apply annual oil treatments.
• Southwest (dry heat, UV exposure): Most species work. UV-blocking finishes are more important than rot resistance in this climate.

Cost Comparison and Final Recommendations

For a 300 sq ft deck, here is what materials alone typically cost using 5/4×6 decking boards:

• Pressure-treated pine: $450 to $900
• Western red cedar: $1,050 to $1,800
• Redwood (heartwood): $1,500 to $2,700
• Garapa: $900 to $1,650
• Ipe: $1,350 to $2,400

If budget is the priority and you do not mind regular staining, pressure-treated pine is the practical choice. For the best balance of natural beauty, decay resistance, and workability, cedar wins for most homeowners. When longevity matters above all else, ipe is the clear leader. Consider the total cost of ownership over 20 years, including stain, sealer, and board replacements, and the upfront premium for hardwood decking often pays for itself.
