Choosing the right material for your deck is one of the most important decisions you’ll make for your outdoor living space. The material you choose affects how your deck looks, how long it lasts, how much maintenance it requires, and ultimately, how much you’ll spend over the lifetime of the investment.

This guide covers the most popular outdoor deck wood types – pressure-treated lumber, cedar, redwood, tropical hardwoods – and compares them to composite decking, helping you make an informed decision for your home.

Why Your Choice of Deck Material Matters

Not all decking materials perform the same in every climate. Here in Michigan – where winters can be harsh, summers humid, and freeze-thaw cycles brutal – you need a deck material that can handle it all without falling apart.

Beyond durability, you’ll want to consider:

• Appearance – How will it look when first installed, and how will it age over time?
• Maintenance – How much time and money will you invest in upkeep each year?
• Cost – What’s the upfront cost versus long-term cost including maintenance?
• Longevity – How long can you realistically expect the deck to last?
• Sustainability – Where does the material come from and what’s its environmental impact?

Let’s break down each wood deck type and what you can expect.

Types of Wood for Outdoor Decks

1. Pressure-Treated Lumber

Pressure-treated (PT) lumber is the most widely used deck wood type in North America. It’s wood (usually pine) that’s been chemically treated to resist rot, insects, and moisture.

Pros:

• Widely available and affordable
• Resistant to rot and insects due to chemical treatment
• Structural lumber is available for framing and substructure
• Can be painted or stained

Cons:

• Requires sealing or staining every 1-3 years to maintain appearance and prevent warping
• Prone to cracking, splitting, and warping – especially in Michigan’s climate
• Can be rough and splinter over time
• Newer PT formulations (ACQ and CA) are corrosive to standard fasteners – requires stainless steel or hot-dipped galvanized hardware
• Treated chemicals raise environmental concerns

Typical Lifespan: 15-25 years with proper maintenance

Best For: Budget-conscious projects where significant ongoing maintenance is acceptable

2. Cedar

Western red cedar is a popular natural wood deck option known for its beauty and natural resistance to rot and insects. Its reddish-brown tones and tight grain give it a warm, appealing look.

Pros:

• Naturally resistant to rot and insects (no chemical treatment needed)
• Lightweight and easy to work with
• Beautiful natural appearance
• Less prone to warping than pressure-treated lumber when properly maintained
• Splinter-resistant compared to PT lumber

Cons:

• More expensive than pressure-treated lumber
• Still requires annual cleaning and sealing or staining every 1-3 years
• Will fade to a silver-grey without regular maintenance
• Supply can be limited and quality varies
• Not as hard as tropical hardwoods – more susceptible to dents and scratches from furniture

Typical Lifespan: 15-30 years with proper maintenance

Best For: Homeowners who want a natural wood look and are willing to maintain it regularly

3. Redwood

Redwood is a premium natural wood deck material known for its rich, warm color and exceptional natural rot resistance. It was once the gold standard for outdoor decking.

Pros:

• Stunning natural appearance with rich color tones
• Naturally resistant to rot, insects, and decay
• Relatively straight grain, resists warping
• Lightweight

Cons:

• Increasingly expensive and harder to source – old-growth redwood is largely protected
• Most commercially available redwood today is second-growth, which doesn’t offer the same durability as old-growth
• Still requires regular sealing to maintain color and prevent grey weathering
• Premium cost may not deliver the longevity it once did

Typical Lifespan: 20-30 years (old-growth); 15-25 years (second-growth) Best For: Homeowners in regions with easy access to quality redwood who prioritize natural aesthetics

4. Tropical Hardwoods (Ipe, Cumaru, Tigerwood)

Tropical hardwoods like ipe (also called Brazilian walnut), cumaru, and tigerwood are the most durable natural wood deck options available. These dense, exotic woods are prized for their remarkable hardness and natural weather resistance.

Pros:

• Extremely dense and durable – ipe can last 40+ years
• Naturally resistant to rot, insects, mold, and mildew
• Beautiful, rich appearance with unique grain patterns
• Minimal sealing required compared to softwoods (though oiling is recommended to maintain color)

Cons:

• Expensive – often 3-5x the cost of pressure-treated lumber
• Very heavy and harder to work with – specialized tools and skilled labor required
• Sourcing concerns: many tropical hardwoods come from rainforests; look for FSC-certified options if choosing this route
• Will weather to a silver-grey without regular oiling (though this is largely aesthetic)
• May not be readily available in the Midwest

Typical Lifespan: 25-40+ years

Best For: Homeowners with a larger budget who want a natural wood deck that can outlast other options

Wood vs. Composite Decking: A Side-by-Side Comparison

In recent years, composite decking has become the top choice for homeowners who want the look of wood without the maintenance demands. Here’s how wood deck types compare to composite:

Feature	Pressure-Treated	Cedar	Ipe	Composite (Trex)
Upfront Cost	$	$$	$$$-$$$$	$$-$$$
Maintenance Required	High	High	Moderate	Low
Sealing / Staining	Every 1-3 years	Every 1-3 years	Oiling recommended	Not required
Splinters	Yes	Minimal	Minimal	No
Rot / Decay	Possible	Possible	Very unlikely	Not applicable
Fade Resistance	Poor	Poor-Moderate	Moderate	Excellent
Lifespan	15-25 years	15-30 years	25-40+ years	25-50+ years
Warranty	None	None	None	Up to 50 years (Trex)
Eco-Friendly	Moderate	Better	Varies	Yes (recycled materials)

Composite Decking: The Low-Maintenance Alternative

Composite decking like Trex is made from a combination of recycled wood fiber and recycled plastic. It’s engineered to look like natural wood while resisting the problems that wood decks face: rot, splinters, fading, and the need for constant sealing or staining.

Why homeowners in Michigan choose composite:

• Weather-resistant. Composite boards are designed for freeze-thaw cycles, heavy moisture, and UV exposure – exactly what Michigan delivers.
• No sealing or staining. Once installed, composite decking only needs occasional cleaning.
• Splinter-free. Safe for barefoot use, especially important for families with kids or pets.
• Long warranty. Premium composite products like Trex come with warranties up to 50 years on material and fade/stain resistance.
• Consistent appearance. Unlike natural wood, composite boards don’t warp, crack, or silver unevenly over time.
• Sustainability. Trex products are made from 95% recycled materials, including reclaimed wood fiber and recycled plastic film.

The trade-off is upfront cost – composite typically costs more than pressure-treated lumber initially. But when you factor in the eliminated cost of sealing, staining, and repairs over 10-20 years, the total cost of ownership is often comparable or better.

Tips for Choosing the Right Deck Material for Your Home

Here’s how to think through your decision:

Consider your maintenance tolerance. If you’re willing to seal and stain every couple of years, natural wood can deliver beautiful results. If you’d rather spend your weekends on the deck rather than maintaining it, composite is the smarter choice.

Think long-term cost. A cheaper material with high maintenance costs often ends up more expensive over 15-20 years than a premium option that requires little upkeep.

Factor in Michigan’s climate. Freeze-thaw cycles and humidity are hard on natural wood. Materials that don’t perform in wet, variable climates will show it early. Composite and tropical hardwoods tend to hold up better than softwoods in Michigan conditions.

Know your local suppliers and contractors. Not all materials are equally available or installers equally experienced. Choosing a contractor who specializes in your preferred material makes a significant difference in the final result.

Check warranties. Natural wood decking comes with no warranty. Premium composite products offer manufacturer warranties on materials and performance. If long-term peace of mind matters to you, this is a meaningful difference.

Frequently Asked Questions

What is the most durable wood for outdoor decks? Among natural wood options, tropical hardwoods like ipe are the most durable, with lifespans of 25-40+ years. However, composite decking (like Trex) offers comparable or better longevity with far less maintenance.

What is the lowest maintenance deck wood? Composite decking requires the least maintenance of any decking material – it doesn’t need sealing, staining, or sanding. Among natural woods, tropical hardwoods like ipe require the least maintenance, though they still benefit from periodic oiling.

Is cedar or pressure-treated lumber better for a deck? Cedar has a natural resistance to rot and insects that pressure-treated lumber achieves artificially through chemical treatment. Cedar tends to be smoother, more attractive, and less prone to warping. However, it’s more expensive. Both require regular sealing/staining for long-term performance.

How long does a wood deck last? It depends on the material and maintenance. Pressure-treated lumber typically lasts 15-25 years, cedar 15-30 years, and tropical hardwoods 25-40+ years with proper care. Composite decking is rated for 25-50 years and carries manufacturer warranties that wood products don’t.

What type of decking is best for cold climates like Michigan? In Michigan’s climate, materials that can handle freeze-thaw cycles, moisture, and humidity without warping, cracking, or rotting are essential. Composite decking (like Trex), tropical hardwoods, and properly maintained cedar all perform well. Standard pressure-treated softwood is the most susceptible to the effects of Michigan winters.
