Cedar vs Trex vs PVC Decking: Honest Pros and Cons Guide

Cedar costs less upfront but demands regular maintenance, Trex composite strikes a middle ground on price and durability, and PVC decking costs the most but is virtually maintenance-free. The right choice depends on how much you want to spend now versus later, how much upkeep you're willing to do, and which look you prefer. This guide breaks down each material honestly — no brand cheerleading, just the trade-offs.

What Are These Three Materials, Exactly?

Before comparing, it helps to know what you're actually buying:

• Cedar — A naturally rot-resistant softwood. Western red cedar is the standard species used for decking. It's real wood, with all the beauty and vulnerability that implies.
• Trex (composite) — A blend of roughly 95% recycled wood fibers and plastic, pressed into boards designed to look like wood. Trex is the largest composite brand, but competitors like TimberTech and Fiberon use similar formulas. Throughout this article, "composite" and "Trex" are used somewhat interchangeably, though specific pricing references are for Trex products.
• PVC (cellular PVC) — 100% synthetic boards made entirely from polyvinyl chloride, with no wood fibers. Brands include TimberTech AZEK, Wolf, and Zuri. Because there's no organic material inside, PVC won't absorb moisture at all.

How Much Does Each Material Cost Installed?

Material cost is only part of the picture — labor, substructure, and fasteners matter too. But since the substructure (typically pressure-treated joists) is similar regardless of decking material, the price difference comes mostly from the boards themselves and any specialized fasteners.

These ranges reflect 2024 pricing and vary significantly by region, deck complexity, and contractor markup. A simple rectangular deck on flat ground will land near the low end; a multi-level deck with curves, stairs, and built-in benches will push costs higher regardless of material.

One important nuance: cedar's upfront savings shrink when you factor in long-term maintenance costs — staining, sealing, and occasional board replacement. More on that below.

How Long Will Each Material Last?

Lifespan depends heavily on climate, sun exposure, and how well you maintain the deck.

• Cedar: With diligent maintenance (staining and sealing every 1–3 years), a cedar deck can last 15–25 years. Without maintenance, expect significant graying, splintering, and rot in as few as 8–10 years, especially in wet climates.
• Trex composite: Trex offers a 25-year limited warranty on most product lines and a 25-year fade-and-stain warranty on its higher-end Transcend line. Real-world lifespan is roughly 25–30 years. Early-generation composites (pre-2010) had mold and staining issues, but current formulations with protective polymer caps have largely solved those problems.
• PVC: Manufacturers like AZEK offer limited lifetime structural warranties and 50-year fade-and-stain warranties. Realistic lifespan is 30–50+ years because there's no wood fiber to rot or attract mold.

A key distinction: composite and PVC warranties typically cover the boards only, not the substructure. Your pressure-treated framing will still need inspection and potential replacement after 15–20 years regardless of what's on top.

What Maintenance Does Each Material Require?

This is where the three materials diverge the most, and it's often the deciding factor.

Cedar Maintenance

Cedar requires the most hands-on care of the three. Here's a realistic maintenance schedule:

• Staining or sealing every 1–3 years, depending on sun exposure and foot traffic. A gallon of quality exterior stain runs $30–$60, or you can hire a pro for roughly $2–$5 per square foot.
• Power washing annually (carefully — too much pressure damages wood grain).
• Board inspection each spring for splintering, warping, or soft spots that indicate rot.
• Occasional board replacement when individual planks deteriorate beyond repair.

Over a 20-year span, maintenance costs on a 300-square-foot cedar deck can easily add $3,000–$6,000 if you hire out the staining. DIY reduces that, but it still costs your weekends.

Trex Composite Maintenance

Modern capped composites are genuinely low-maintenance — not zero-maintenance, but close:

• Periodic cleaning with soap and water or a composite deck cleaner once or twice a year.
• No staining, sealing, or painting — ever.
• Mold or mildew can appear on the surface in shady, humid areas. It sits on top of the cap rather than penetrating, so it washes off. However, it can be persistent in heavily shaded environments.

PVC Maintenance

PVC is the lowest-maintenance option available:

• Soap-and-water cleaning once or twice a year is typically all that's needed.
• No staining, sealing, or painting.
• Mold and mildew resistance is superior to composite because there are no wood fibers for organic growth to feed on.

How Do They Look and Feel Underfoot?

Appearance is subjective, but there are some objective differences worth noting:

• Cedar wins on authenticity. The grain pattern, warm color, and the way it weathers to a silver-gray patina (if left unstained) are things synthetic materials try to replicate but can't fully match. It also feels like real wood underfoot — because it is.
• Trex composite has improved dramatically in appearance. Higher-end lines like Trex Transcend use multi-tonal color streaking that mimics tropical hardwoods reasonably well. Up close, though, the repeating pattern in the embossing can look manufactured. Composites feel slightly different underfoot — firmer, less give than natural wood, and the surface can feel waxy or plasticky when wet.
• PVC offers the most consistent color and surface texture. Some homeowners find PVC looks "too perfect" — lacking the natural variation of wood. It can also feel hollow or drum-like underfoot if not installed over tightly spaced joists. On the positive side, PVC stays cooler in direct sunlight than dark-colored composites.

One often-overlooked factor: heat retention. Dark composite boards can get uncomfortably hot in direct summer sun — hot enough that bare feet are unpleasant. PVC generally runs cooler, and cedar stays the coolest of the three. If your deck faces south with no shade, this matters.

How Does Each Material Handle Moisture and Insects?

Cedar contains natural oils (thujaplicins) that resist rot and deter insects, but this resistance diminishes over time as the oils leach out. In consistently wet or ground-contact situations, cedar can still rot. Termites generally avoid cedar, but carpenter ants do not.

Trex composite resists rot and insect damage far better than any natural wood because the polymer cap prevents moisture absorption. However, the wood-fiber core can absorb moisture if the cap is damaged — by a deep scratch or a poorly made cut that exposes the core. In practice, this is rarely a problem.

PVC is impervious to moisture and insects. It will not rot, swell, or attract any wood-boring organisms. Period. This makes it the clear choice for waterfront properties, pool surrounds, or any application where the deck will be regularly soaked.

Environmental Considerations

If sustainability matters to you, here's a fair comparison:

• Cedar is a renewable resource, and Western red cedar forests are managed under sustainable forestry practices in the Pacific Northwest and British Columbia. However, old-growth cedar harvesting remains controversial, and the carbon footprint of harvesting and shipping is real.
• Trex composite is made from roughly 95% recycled material — reclaimed wood and recycled polyethylene (plastic bags, film wrap). According to Trex, the company diverts over 800 million pounds of plastic and wood scrap from landfills annually. However, composite boards are difficult to recycle at end of life.
• PVC is petroleum-based and energy-intensive to manufacture. PVC production has drawn criticism from environmental groups, though some manufacturers like AZEK have introduced recycling programs. At end of life, PVC decking can sometimes be recycled back into new boards, but recycling infrastructure is limited.

None of these materials is perfectly "green." If environmental impact is your top priority, cedar from certified sustainable sources is probably the most straightforward choice — but its shorter lifespan means more frequent replacement.

Which Material Should You Choose?

There's no universally best option. Here's a framework based on common homeowner priorities:

A few final practical notes:

• Get material samples before committing. Most lumber yards and home centers carry samples of all three. Feel them, look at them in sunlight, and pour water on them.
• Ask your builder what they prefer to install. Some contractors specialize in composite or PVC and will do better work with those materials. Others are experienced wood builders. Skill with the specific material affects the final quality.
• Check local building codes. Some municipalities have restrictions on certain materials near fire-prone areas. Composite and PVC may require specific fire-rating documentation.
