Cedar vs. Ipe: Which Wood Lasts Longer Outdoors?

When you’re choosing wood for an outdoor project—whether it’s a deck, fence, pergola, or garden structure—longevity matters just as much as appearance. Two of the most commonly compared options are Western Red Cedar and Ipe (Brazilian Walnut), and while both perform well outdoors, they age very differently over time.

I’ve seen cedar projects that still look great after 20 years—and I’ve also seen Ipe decks that outlast the hardware holding them together. The real difference comes down to how long you want the wood to last, how much maintenance you’re willing to do, and how the space will be used.

Quick Answer (If You’re Short on Time)

Ipe lasts longer outdoors than cedar—often 25–40+ years.
 Cedar typically lasts 15–25 years with proper care.

That said, longevity alone doesn’t determine the “best” choice.

Why Wood Choice Makes or Breaks Outdoor Projects

As we explain in this related guide, Best Wood for Outdoor Project:

“When it comes to outdoor projects—decks, fences, pergolas, or garden structures—the type of wood you choose can make or break your build.”

That statement comes from real-world experience—not theory. Outdoor wood must handle sun exposure, moisture, insects, and structural stress year after year. Choosing the wrong species can mean warping, cracking, or rot far sooner than expected.

What “Lasts Longer” Really Means Outdoors

Most articles oversimplify durability. In real outdoor conditions, longevity can mean:

• Staying structurally sound
• Resisting rot and insects
• Maintaining appearance over time
• Requiring minimal upkeep

A wood can last decades structurally but look rough—or look great while quietly deteriorating underneath. That’s why comparing cedar and Ipe requires more nuance than just a lifespan number.

Western Red Cedar: Proven, Flexible, and Forgiving

Best for:
 Decking, fencing, pergolas, privacy screens, outdoor furniture

Why Cedar Performs Well Outdoors

Western Red Cedar contains natural oils and tannins that resist decay and insects. It’s lightweight, stable, and easy to work with—making it a favorite for both contractors and DIY projects.

Real-World Longevity

• 15–25 years outdoors
  
• Longer when elevated and sealed
• Shorter if installed in constant moisture or shade

Pros

• Naturally rot- and insect-resistant
• Easy to cut, fasten, and install
• Ages gracefully to a silvery gray
• More budget-friendly than hardwoods

Cons

• Softer wood (can dent or scratch)
• Requires sealing to maintain color
• Not ideal for high-traffic areas

Real-world insight:
 Cedar performs best above ground with good airflow. Drainage and spacing matter more than people realize.

Ipe (Brazilian Walnut): Built for Extreme Durability

Best for:
 High-traffic decks, stairs, pool decks, commercial applications

Why Ipe Lasts So Long

Ipe is one of the densest hardwoods available. Its natural hardness makes it highly resistant to moisture, insects, rot, and wear—even in harsh climates.

Real-World Longevity

• 25–40+ years outdoors
  
• Often outlasts fasteners and substructures
• Minimal maintenance required for performance

Pros

• Exceptional durability and hardness
• Naturally rot- and insect-resistant
• Excellent for wet or high-use areas
• Strong long-term investment

Cons

• Heavy and difficult to work with
• Requires pre-drilling
• Higher upfront cost
• Will gray unless oiled periodically

Pro tip:
 Always use stainless steel fasteners with Ipe—lesser hardware corrodes long before the wood fails.

Cedar vs. Ipe: Side-by-Side Comparison

Climate Matters More Than Most People Think

In humid or rainy climates, Ipe’s density gives it a clear edge.
In well-ventilated, above-ground builds, cedar holds up remarkably well.

Common mistake:
 Using cedar where hardwood performance is required—or overspending on Ipe when cedar would last decades.

Which Wood Is Right for Your Project?

Choose cedar if you want:

• Easier installation
• Lower upfront cost
• A natural, lightweight material
• Willingness to perform periodic maintenance

Choose Ipe if you want:

• Maximum lifespan
• Minimal maintenance
• High durability in heavy-use areas
• Long-term value over initial cost

Final Thoughts

So—which wood lasts longer outdoors?

✔ Ipe wins on pure longevity and durability.
 ✔ Cedar excels in versatility, workability, and value.

The best choice depends on how the wood will be used, your climate, and how much maintenance you want to take on. Matching the material to real conditions—not just labels—makes all the difference.
