How to Choose the Right Decking Material
Choosing a decking material is one of the most important decisions in any outdoor project. The material you select determines how your deck looks, how long it lasts, how much maintenance it needs, and what it ultimately costs over its lifetime.
Most buyers compare just two or three options. This guide covers all seven major categories — from budget pressure-treated pine to premium Ipe hardwood — so you can make a fully informed decision based on your climate, budget, and priorities.
Important: We're a hardwood supplier, so we're transparent about our perspective. That said, we've included honest pros and cons for every material — including our own. The data (Janka ratings, fire ratings, lifespans) comes from industry-standard sources.

Decking Materials Explained
Detailed pros, cons, and best-use scenarios for each material.
Ipe Hardwood (Brazilian Walnut)
The gold standard in decking — unmatched lifespan, density, and beauty
Ipe is widely considered the best natural decking material available. With a Janka hardness of 3,680 lbf — over 8× harder than pressure-treated pine — it resists scratches, dents, rot, insects, and fire (Class A rated). Ipe decking can last up to 75+ years with virtually zero maintenance. Left untreated, it weathers to an elegant silver-gray; with annual oiling, it retains its rich chocolate-brown color.
Pros
- Up to 75+ year outdoor lifespan — outlasts every alternative
- Class A fire rating (same as concrete and steel)
- Naturally insect-proof and rot-resistant (no chemical treatment)
- Stays cooler than composite in direct sun
- Minimal maintenance — never needs replacing
Cons
- Higher upfront cost than softwood or composite
- Requires pre-drilling due to extreme density
- Natural color variation between boards
Best for: Homeowners who want a lifetime deck. High-traffic residential and commercial decks, pool surrounds, waterfront applications, and any project where long-term value matters.
Cumaru Hardwood (Brazilian Teak)
Premium hardwood performance at a better price point
Cumaru delivers nearly identical durability to Ipe at a more accessible price. With a Janka hardness of 3,330 lbf and warm reddish-brown tones, it's the go-to alternative for buyers who want premium hardwood without the premium-tier price. It offers Class A fire rating, 50+ year lifespan, and natural resistance to rot and insects.
Pros
- 50+ year lifespan with minimal maintenance
- Nearly as hard as Ipe (3,330 vs 3,680 Janka)
- Beautiful warm reddish-brown to golden tones
- More affordable than Ipe
- Class A fire rated
Cons
- More color variation between boards than Ipe
- Initial tannin bleeding when wet (temporary)
- Still requires pre-drilling
Best for: Budget-conscious homeowners who still want premium hardwood. Residential decks, pool decks, and commercial projects where cost-to-lifespan ratio matters.
Cedar Decking
Affordable and attractive, but limited lifespan
Western Red Cedar is a popular domestic softwood known for its pleasant aroma and reddish-brown appearance. It's lightweight and easy to work with, but its softness (350 Janka) means it dents easily and degrades relatively fast compared to tropical hardwoods. Cedar requires annual sealing/staining and typically lasts 15–20 years before needing replacement.
Pros
- Affordable upfront cost
- Lightweight and easy to cut/install
- Pleasant natural aroma
- Moderate natural insect resistance
- Widely available at home centers
Cons
- Extremely soft — dents and scratches easily
- Only 15–20 year lifespan outdoors
- Requires annual sealing/staining (high lifetime cost)
- Prone to warping, splitting, and checking
- Not fire-resistant (Class C)
Best for: DIY projects on a budget, temporary structures, or areas with very low foot traffic.
Pressure-Treated Pine
The lowest cost option — but you get what you pay for
Pressure-treated (PT) pine is the cheapest decking option upfront. The wood is infused with chemical preservatives (ACQ or MCA) to resist rot and insects. However, it's soft (690 Janka), warps significantly, develops splinters, and typically needs replacement within 10–15 years. When you factor in maintenance costs and replacement cycles, PT pine can actually cost more than hardwood over 25+ years.
Pros
- Lowest upfront cost of any decking material
- Widely available everywhere
- Easy to cut and fasten
- Chemical treatment provides rot resistance
Cons
- Only 10–15 year lifespan
- Warps, cups, and twists as it dries
- High splinter risk — uncomfortable barefoot
- Requires annual sealing and periodic staining
- Chemical preservatives raise environmental concerns
- Total cost of ownership often exceeds hardwood
Best for: Tight budgets where longevity isn't the priority. Utility structures, substructure framing (joists under hardwood decking).
Composite Decking (Trex, TimberTech, Fiberon)
Low maintenance, but shorter lifespan and heat issues
Composite decking is made from a blend of wood fibers and plastic (polyethylene or polypropylene). Marketed as "low maintenance," composites don't need staining but do require periodic cleaning. They're warrantied for 25 years but often show significant fading, staining, mold, and structural degradation well before that. Composites retain significantly more heat than natural wood — a major concern in warm climates.
Pros
- No staining required
- Won't splinter
- Consistent manufactured color
- Many color options available
- Moderate warranty coverage
Cons
- Gets extremely hot in direct sun (up to 35°F hotter than wood)
- 15–25 year realistic lifespan (not the warrantied lifespan)
- Scratches permanently — cannot be sanded and refinished
- Can develop mold and mildew staining
- Fades over time despite UV treatments
- Contains plastic — not biodegradable
- Higher upfront cost than many assume
Best for: Homeowners who prioritize not staining and accept a shorter lifespan. Shaded decks in moderate climates where heat isn't an issue.
PVC Decking (AZEK, etc.)
100% plastic — moisture-proof but expensive and hot
PVC (polyvinyl chloride) decking is 100% plastic with no wood fibers. It's completely moisture-proof, making it ideal for pool decks or coastal areas with constant water exposure. However, PVC decking is the hottest of all materials in direct sunlight, has a hollow sound when walked on, and is one of the most expensive options — often costing as much as Ipe while lasting only 25–30 years.
Pros
- Completely moisture-proof
- Won't rot, warp, or splinter
- Easy to clean
- Good stain resistance
Cons
- Extremely hot in direct sun — the hottest of all decking materials
- Very expensive (comparable to hardwood)
- 100% plastic — not eco-friendly
- Hollow sound and feel underfoot
- Cannot be refinished or sanded
- Only 20–30 year lifespan
Best for: Wet environments where moisture is the #1 concern (covered docks, constant splash zones) and heat is not.
Thermally Modified Wood
Heat-treated softwood — better than untreated, but limited
Thermally modified wood is softwood (typically ash, pine, or poplar) heated to 400°F+ in an oxygen-free kiln. This process removes moisture and modifies the cell structure, improving rot resistance and dimensional stability. However, it also makes the wood more brittle and reduces its structural strength. It's a middle-ground option that outperforms untreated softwood but doesn't approach tropical hardwood durability.
Pros
- Better rot resistance than untreated softwood
- Improved dimensional stability
- No chemical treatments
- Lighter weight than tropical hardwood
- Attractive darkened color
Cons
- More brittle — can crack under impact
- Reduced structural strength
- Only 20–30 year lifespan
- Limited availability in some regions
- Color fades without maintenance
- More expensive than cedar but less durable than hardwood
Best for: Homeowners who want a "natural" look without chemicals but don't need maximum durability.

Decking Material FAQ
Common questions about choosing a decking material.
Ipe hardwood is widely considered the best overall decking material due to its unmatched combination of durability (3,680 Janka hardness), lifespan (up to 75+ years), Class A fire rating, natural insect and rot resistance, and minimal maintenance requirements. While it costs more upfront, its total cost of ownership is lower than most alternatives because it never needs replacing.
Ipe hardwood lasts the longest of any decking material — up to 75+ years outdoors with minimal maintenance. Cumaru and Massaranduba follow at 50+ years. By comparison, composite lasts 15–25 years, cedar 15–20 years, and pressure-treated pine only 10–15 years.
It depends on your priorities. Composite requires less staining but gets extremely hot in sunlight, lasts only 15–25 years, cannot be refinished, and contains plastic. Tropical hardwood (Ipe, Cumaru) lasts 3–5× longer, stays cooler, is a natural product, and can be refinished. Over 25+ years, hardwood often costs less overall due to zero replacement cycles.
Natural wood decking stays the coolest. Light-colored hardwoods like Garapa are particularly cool underfoot. Composite and PVC decking retain significantly more heat — up to 35°F hotter than wood in direct sunlight. This is a critical factor for pool decks and warm-climate installations.
When measured by cost per year of usable life, tropical hardwood offers the best value. Ipe at $10–15/sq ft installed lasts 75+ years (~$0.13–0.20/sq ft/year). Composite at $8–12/sq ft installed lasts 20 years (~$0.40–0.60/sq ft/year). Pressure-treated at $5–8/sq ft installed lasts 12 years (~$0.42–0.67/sq ft/year) — plus replacement costs.
Ipe and Garapa are excellent choices for pool decks. Both resist water damage, rot, and insects. Garapa's light golden color stays particularly cool in sunlight. Composite and PVC should be avoided near pools in sunny areas due to extreme surface heat. All tropical hardwoods are naturally resistant to the moisture, chlorine, and foot traffic around pools.
Cedar is an adequate budget decking material but has significant limitations. At only 350 Janka hardness (compared to Ipe at 3,680), cedar dents easily and typically lasts just 15–20 years with annual maintenance. It's best for low-traffic areas or temporary installations. For a deck you want to last, tropical hardwood is a better investment.
Responsibly sourced tropical hardwood is arguably the most eco-friendly choice. It's a natural, renewable, biodegradable material that lasts 50–75+ years — meaning far fewer replacement cycles and less waste over time. Composite contains plastic and typically ends up in landfills after 20 years. Pressure-treated pine uses chemical preservatives.
