Composite vs Wood Decking: What Holds Up Best in Arkansas?

A new deck is one of the best investments a homeowner can make — especially in Arkansas where outdoor living season runs a good eight months of the year. But the material you choose determines how much maintenance you’re doing, how long it lasts, and ultimately whether you got your money’s worth.

The two most common choices are pressure-treated wood and composite decking, and the right answer depends on your budget, your tolerance for maintenance, and honestly how much time you want to spend on upkeep in July.

The Arkansas Climate Problem

Before getting into materials, it’s worth understanding why the choice matters more here than in a lot of other states.

Central Arkansas sits in a humid subtropical climate — hot, humid summers followed by winters that can swing dramatically. That combination is hard on outdoor wood. You get:

• Moisture absorption during humid months, which causes wood to swell
• Rapid drying during hot summers, which causes wood to shrink and crack
• UV exposure that bleaches and dries out wood fibers
• Mold and mildew that thrive in the humidity on any surface that holds moisture

That cycle of expansion and contraction, year after year, accelerates wear significantly compared to drier climates. It’s why a wood deck that lasts 25 years in Colorado might show serious wear in 12–15 years here without consistent maintenance.

Pressure-Treated Wood

Pressure-treated (PT) lumber is the traditional choice and still the most common decking material you’ll see on homes across Conway and Central Arkansas.

The upside:

• Lowest upfront cost by a significant margin — typically $15–$25 per square foot installed vs. $35–$60+ for composite
• Easy to cut, nail, and repair on-site
• Widely available from any lumber yard
• Can be stained virtually any color

The real maintenance picture in Arkansas:

This is where a lot of homeowners underestimate the commitment. A PT wood deck in our climate needs:

• Cleaning annually — power washing or scrubbing to remove mold, mildew, and dirt
• Sealing or staining every 2–3 years to protect against moisture and UV damage
• Board inspection each year for cracking, splitting, or popped fasteners
• Post and joist inspection for rot, particularly at ground contact points

Skip two or three maintenance cycles and you’ll be looking at board replacements within a decade. Factor in the cost of stain, sealant, and your time (or hiring it out) over 15 years and the “cheaper” option often isn’t.

Best for: Homeowners with a tighter upfront budget who are genuinely willing to maintain it, or situations where a specific look or custom size makes wood the better fit.

Composite Decking

Composite decking is made from a blend of wood fiber and recycled plastic. Brands like Trex, TimberTech, and Fiberon have become the dominant names, and the product has improved dramatically over the past decade.

The upside:

• Dramatically lower maintenance — annual cleaning with soap and water is typically all that’s needed
• Won’t rot, splinter, or require sealing
• Holds up well against moisture and UV in our climate
• Stays cooler underfoot than older composite products (newer capped composites especially)
• Looks consistently good for 25–30 years with minimal effort

The honest downsides:

• Upfront cost is significantly higher — plan on $35–$60 per square foot installed depending on the brand and complexity
• Heat retention — composite decks in full Arkansas sun get hot. Capped composite performs better than uncapped, but it’s worth considering shade options if your deck gets direct afternoon sun
• Repair is harder — matching boards from a specific product line years later can be tricky if a board gets damaged
• Looks less natural — the gap between composite and real wood appearance has closed considerably, but purists still notice

Best for: Homeowners who want a deck that looks great with minimal upkeep, plan to stay in the home long-term, and can absorb the higher upfront cost.

Head-to-Head Comparison

The 10-Year Cost Reality

One useful exercise before deciding: estimate the 10-year total cost, not just the install price.

For a 400 sq ft deck:

• PT Wood install: $8,000. Add staining every 3 years ($400/time), cleaning supplies, and potential board replacement — realistic 10-year total: $10,500–$12,000
• Composite install: ~$18,000. Cleaning supplies only. Realistic 10-year total: $18,500–$19,000

The gap closes, but composite still costs more over a decade. What you’re buying is your time and the certainty of consistent appearance.

What to Ask a Deck Builder Before Signing

When you reach out to deck builders in the Conway area, these questions separate the professionals from the weekend warriors:

1. Are you licensed and insured in Arkansas? Deck construction requires permits in most municipalities — a contractor who skips this is cutting corners.
2. Do you handle the permit? They should. If they suggest you pull it yourself, that’s a flag.
3. What composite brands do you install? There’s a big quality gap between entry-level and premium composite lines. Ask what they recommend and why.
4. What’s included in the substructure? The decking boards are only part of it — the joists, beams, and ledger board are what the whole thing sits on. Understand what lumber grade they’re using for the framing.
5. Do you offer a labor warranty? Separate from the material warranty.

Bottom Line

For most Conway area homeowners who plan to stay in their home 10+ years and want to actually enjoy the deck instead of maintaining it: composite is worth the upfront premium.

If budget is the primary constraint or you genuinely enjoy the natural wood look and don’t mind the upkeep: pressure-treated wood is a solid choice with proper maintenance.

Either way, the deck itself isn’t the biggest variable — the contractor building it is. A well-built wood deck beats a poorly-built composite deck every time.
