Composite vs Wood Decks in Texas: Cost, Lifespan and Heat Compared

Is composite or wood decking better in Texas?

For most Central Texas homeowners, capped composite in a lighter color is the better long-term choice. It handles our UV, heat, humidity swings, and sudden storms without rotting, splintering, or needing a sealer, and it typically lasts 25 to 30 years. Wood is the better choice when the up-front budget is tight, when you want the look and feel of real wood, or when the deck sits in full sun and you want the coolest possible surface underfoot.

Neither answer is universal. A covered deck, a small budget deck behind a rental, a shaded deck under live oaks, and an exposed pool deck all point to different materials. The sections below give you the numbers to decide for your own yard.

How much does composite decking cost compared to wood in Austin?

Installed pricing in the Austin metro for 2026 runs $15 to $25 per square foot for pressure-treated pine, $30 to $45 for Western red cedar, and $35 to $55 for Trex or TimberTech composite. Ipe hardwood sits above all three at $50 to $75 per square foot. Those figures include labor and materials for the decking tier; stairs, railings, multi-level layouts, and site conditions move the final project number.

In practice, material choice alone can swing a project a long way. The same 300 sq ft deck can be a $14,000 build or a $32,000 build depending on the boards. For a sense of whole projects, a basic 12x16 deck runs $12,000 to $16,000, and a mid-size 16x20 composite deck runs $20,000 to $28,000.

Cedar and composite are closer in up-front price than most people expect. The real up-front gap is between pressure-treated pine and everything else.

Which costs less over 20 years, composite or wood?

Over a 20-year horizon, composite usually costs about the same as wood or less. The reason is maintenance. A wood deck in Central Texas needs cleaning and sealing or staining every 2 to 3 years to hold up against our sun and rain, and each round typically costs $500 to $1,000 if you hire it out. Over 20 years that is roughly 6 to 10 treatments, or somewhere around $3,000 to $10,000, before counting any board replacement.

Composite needs occasional cleaning with soap and water and nothing else. No sanding, no sealer, no stain. That gap in upkeep closes most of the difference in up-front price, and it is why busy families and owners of vacation homes lean toward composite.

Lifespan changes the math too. A pressure-treated deck typically lasts 15 to 20 years here, so a 20-year window may include the start of a replacement or a major repair. A composite deck at 25 to 30 years is still in the middle of its life at year 20. If you plan to stay in the home, composite usually wins on total cost. If you plan to sell in a few years, lower up-front cost carries more weight.

How long do composite and wood decks last in Texas?

Typical lifespans in Central Texas are 15 to 20 years for pressure-treated pine, 20 to 25 years for cedar, 25 to 30 years for Trex or TimberTech composite, and 50 years or more for Ipe. Those numbers assume a deck built correctly and maintained the way the material requires.

Wood that skips its sealing schedule wears out early. The sun dries the surface, rain gets into the checks and cracks, and boards start to cup, split, and splinter. Composite does not have that failure mode, which is why its lifespan is more predictable.

The number that gets left out of most comparisons is the frame. On nearly every composite deck, the joists, beams, and posts are pressure-treated lumber. The boards may be rated for decades, but if the ledger flashing fails or water sits on top of the joists, the frame can give out before the surface does. That is why we treat framing details and footings for our clay soil as part of the material decision, not a separate topic. Our guide on how long a deck lasts in Texas covers the warning signs.

Does composite decking get hotter than wood in the Texas sun?

Yes, dark composite boards can get noticeably hotter than natural wood in direct Texas sun, and some can be uncomfortable for bare feet on a summer afternoon. Cedar in particular tends to stay cooler underfoot. For an uncovered pool deck or a west-facing deck with no shade, this is a real consideration, not a marketing footnote.

The fixes are straightforward. Lighter, heat-reflective colors run cooler than dark browns and grays, and some manufacturers now market boards designed to reduce heat buildup. Shade does even more: a pergola, a gazebo, a covered section, or simply orienting the deck to catch afternoon shade from the house makes a composite deck comfortable through a Central Texas summer.

If you love a dark color and the deck is fully exposed, ask to see and touch samples that have been sitting in the sun before you commit. We would rather you pick a board you can walk on in July than one that only looks good in a showroom.

How do composite and wood handle Texas humidity, rain, and termites?

Central Texas swings between long dry stretches and sudden heavy rain, with muggy summers in between. Wood absorbs and releases moisture through those cycles, which is what drives checking, cupping, and eventually rot in the spots that stay wet longest. Pressure treatment and cedar's natural oils slow that down, and a regular sealing schedule slows it further.

Capped composite has a polymer shell that keeps moisture out of the board, so it does not rot or splinter. It can still show mildew or surface staining in shaded, damp areas, which cleans off with soap and water.

Termites are active across Central Texas. Composite decking is highly resistant to insect damage, and pressure-treated framing is treated to resist termites and decay. Untreated wood in ground contact is the weak point on any deck, which is why posts and footings need to be detailed so wood stays off the soil and water drains away.

Does composite decking expand and contract in Texas heat?

Yes. Composite boards grow and shrink with temperature, mostly along their length, and Central Texas can swing from a winter freeze to triple-digit surface temperatures in the same year. That movement is normal. Problems show up when a board is installed without the end gaps and fastening pattern the manufacturer specifies, which leads to buckling in summer or open gaps at the butt joints in winter.

Wood moves too, but mainly across its width as it takes on and loses moisture. That is why wood decks show widening gaps between boards in a drought and tight gaps after a wet spell. Both materials perform well when the installer follows the manufacturer's gapping and fastener guidance for our climate, and following those instructions is important for keeping the manufacturer warranty intact.

Which one should you choose for your yard?

Choose composite if you want the lowest long-term maintenance, plan to stay in the home for a decade or more, are building around a pool, or simply never want to stain a deck again. Pick a lighter color for exposed decks and plan for shade.

Choose cedar if you want real wood, like the warmer and cooler feel underfoot, and do not mind a maintenance schedule. Choose pressure-treated pine for budget projects, large decks where cost per square foot matters most, or decks that will sit under a roof where sun and rain exposure is reduced.

Many homeowners split the difference with composite decking and aluminum or composite railings, which handle Texas heat and UV well and never need staining. Whichever direction you lean, the frame, the ledger flashing, and footings sized for our expansive clay decide whether the deck actually reaches the lifespan on the brochure.

How do I get an accurate quote for a composite or wood deck?

Ask for the same deck priced in more than one material. Per square foot numbers are a useful starting point, but your real price depends on height, stairs, railings, access, and soil conditions on your lot. Seeing composite and wood priced side by side for your exact design is the fastest way to make the decision.

All Seasons offers a free on-site assessment across the Austin metro. We measure, check drainage and soil, bring samples you can see in your own light, and give you a fixed-price quote that includes permits and HOA submissions.
