Why Composite Decking Makes Sense in Central Texas
Central Texas is hard on outdoor surfaces. Direct sun for nine months of the year, freeze-thaw cycles in winter, humidity in spring and fall, and the occasional triple-digit summer week. Traditional wood decks can withstand all of it, but they need regular resealing, occasional board replacement, and consistent maintenance to look right after five years. Composite decking is built to handle the same conditions without a maintenance schedule.
Modern capped composite decking is a structural mix of recycled wood fibers and polymer, with a hard polymer cap on the top and sides. The cap is what makes the difference. It resists UV fade, splintering, water absorption, and stain penetration. The structural core handles the load; the cap handles the weather. Talk through your project with us, and we’ll provide a verbal pricing range during a free initial site visit.
Composite is not the cheapest deck material. It runs higher than pressure-treated pine and roughly even with mid-grade cedar at purchase, but the maintenance cost over a 20-year ownership window is a fraction of either. For homeowners who want a deck that looks the same in year 15 as it did in year one, composite is the right choice.
Trex, TimberTech, and Fiberon: How They Compare
The composite category is dominated by three manufacturers, each of which makes both premium and value-tier product lines. We install all three. Brand recommendation depends on your color preference, budget, and how the surface temperature performs in full sun. Here is what differentiates each.
Trex (Transcend and Enhance lines)
Trex Transcend is the premium tier: a capped-polymer surface on a mineral-based core, a 50-year limited residential warranty, and the broadest color palette in the category. Transcend boards hold their color well in direct UV exposure (an important consideration for west-facing decks here). Trex Enhance is the more affordable line, capped on four sides, with a 25-year fade-and-stain warranty. Enhance is the better value choice when the deck is shaded or covered; Transcend is our recommendation for full-sun installations.
TimberTech (AZEK and EDGE lines)
TimberTech AZEK is structurally different from the other composites we install: it is a fully polymer board with no wood content in the core. That makes it lighter, more dimensionally stable, and naturally cooler underfoot than wood-composite blends. AZEK carries a 50-year warranty and is the brand we most often recommend for pool decks and full-sun applications where surface temperature matters. TimberTech EDGE is the wood-composite alternative at a lower price point, with a 30-year warranty.
Fiberon (Concordia and Sanctuary lines)
Fiberon Concordia is a premium capped polymer board with a multi-tonal color finish that mimics natural wood grain particularly well, backed by a 50-year limited warranty and strong humidity performance. Fiberon Sanctuary is the more accessible line, a capped composite with a 25-year warranty. We recommend Fiberon when the homeowner wants a wood-grain visual without the wood-deck maintenance schedule.
How we recommend a brand
Brand and line selection are part of the initial site visit. We walk the property to confirm sun exposure, drainage, and structural conditions, then talk through color and texture preferences. We do not push any single brand; the right brand depends on what the deck needs to do.
Building for the Texas Climate
Composite decking works as designed only when the installation accounts for how Texas weather actually affects outdoor materials. The manufacturer’s standard installation guidance is the starting point; the specific adjustments below are where local experience matters.
Thermal expansion gaps
Composite boards expand and contract with temperature. In Texas, the swing from a winter morning to an August afternoon can move a 16-foot board enough to cause buckling if the expansion gaps are not sized correctly. We follow manufacturer specs for board-end gapping and account for the local temperature range in our spacing.
Joist spacing for high-temperature performance
Composite is denser than pressure-treated wood, which means joist spacing matters more than it would for a traditional wood deck. We use 16-inch on-center spacing for straight installations and 12-inch on-center spacing for diagonal or herringbone patterns. Larger joists are required where the board span demands it.
Hidden fastener selection
We use stainless steel hidden fasteners on every composite deck we install. Surface-screwed fasteners are still occasionally used by other builders to save labor costs, but they create entry points for water and dirt and spoil the finished surface appearance. Hidden fasteners cost more in labor and product, and they are non-negotiable in our spec.
Drainage and underside ventilation
Composite holds up better than wood in humidity, but trapped moisture under the deck can still affect adjacent structural framing. We design for airflow between the joist tops and the deck boards, and we slightly slope decks (about 1/4 inch per 4 feet) to shed rainwater.
How a Composite Deck Build Works
Step 1: Site assessment and material walkthrough
Free initial site visit. We photograph existing conditions, measure structural elements, identify drainage and clearance constraints, and discuss material options against your sun exposure and intended use. The visit ends with a verbal pricing range based on our observations and your stated scope.
Step 2: Design and brand selection
Once you decide to move forward, we finalize the design (layout, board pattern, railing style, lighting) and select the specific brand and color. Renderings are provided when the design includes architectural features such as multi-level transitions or built-in seating.
Step 3: Permits and structural drawings
For decks over 200 square feet or attached to the structure, we coordinate permitting through our local partners. Stamped structural drawings provided when required by the authority having jurisdiction.
Step 4: Demolition (if replacement) or excavation (if new)
If we are replacing an existing deck, we handle demolition and debris removal. If new construction, we excavate for footings and confirm soil conditions before pouring concrete.
Step 5: Framing and composite installation
Concrete footings sized to soil conditions. Pressure-treated structural framing per IRC span tables. Composite decking installed with stainless hidden fasteners, manufacturer-specified expansion gaps, and code-compliant railings. A typical residential project takes one to four weeks on-site.
Step 6: Final inspection and handoff
Documented structural inspection of footings, framing, fastening, railing, and surface finish. Handoff packet includes the composite manufacturer’s warranty paperwork (25 to 50 years, depending on brand and line) plus our workmanship warranty on installation.
What Composite Maintenance Actually Looks Like
The maintenance argument for composite is the single biggest selling point of the material, and it is also the most commonly oversold. Here is what is actually true.
Composite decks need annual cleaning. A garden hose and a soft-bristled brush handle most routine cleaning; for stubborn stains (tannin from oak leaves, sunscreen, food spills), a manufacturer-approved composite cleaner once a year is enough. That is the entire maintenance schedule for the surface.
By comparison, a cedar or pressure-treated wood deck needs to be cleaned, dried, and resealed every two to three years to keep its color and surface integrity. The reseal job takes about a full day of homeowner labor (or a few hundred dollars in contractor labor) per cycle, plus material costs.
Over a 20-year ownership window, the composite maintenance cost is roughly 10% of what you spend on a wood deck. That is the math that makes composite the right choice for homeowners who do not want to budget for cyclic refinishing.
Where We Install Composite Decks
Most of our composite installations are in the Hill Country corridor, where homeowners are looking for premium-tier, low-maintenance decking. Our primary residential service zones for this material are:
- West Lake Hills: full-sun west-facing properties where Trex Transcend and TimberTech AZEK earn their warranty premium.
- Bee Cave: large-lot custom builds, often paired with pool decks and integrated lighting.
- Lakeway: lakeside and golf-course-adjacent properties where humidity and UV exposure both matter.
- Westlake: established neighborhoods with HOA composite-only requirements (we know the approval pathways).
- Northwest Hills and River Place: established Austin neighborhoods with heavy tree canopy and the surface-temperature considerations that come with it.
Composite installations also extend across Greater Austin, Round Rock, Cedar Park, Georgetown, and the rest of our coverage area. For commercial composite installations (restaurants, hotels, multi-family properties), we serve Travis, Williamson, Hays, and Bastrop counties.
Frequently Asked Questions About Composite Decking
How long does a composite deck last?
25 to 50 years, depending on the brand and line. Trex Transcend, TimberTech AZEK, and Fiberon Concordia all carry 50-year limited residential warranties. The value-tier lines (Trex Enhance, TimberTech EDGE, Fiberon Sanctuary) carry 25 to 30-year warranties. In our installations, the structural lifespan typically exceeds the surface lifespan; the deck framing and fasteners may need attention before the boards do.
Is composite decking hotter than wood in Texas summers?
Surface temperature varies by brand, color, and material formulation. Light-colored composite boards run a few degrees cooler than dark, and TimberTech AZEK (pure polymer, no wood content) runs noticeably cooler than wood-composite blends. For full-sun pool decks or barefoot applications, we recommend AZEK or a light-colored Trex Transcend. For shaded decks, temperature is not a significant differentiator across brands.
How does composite compare to wood in cost?
At purchase, composite costs more per square foot than pressure-treated pine and is roughly even with mid-grade cedar. Over a 20-year ownership window, composite costs significantly less than wood because there is no resealing labor or material cost every two to three years. Initial site visits are free, and we provide a verbal pricing range during the visit based on your scope and material choice.
Can composite decking be used for pool decks?
Yes, and it is one of the better material choices for pool surrounds. Composite resists pool chemistry (chlorine, saltwater), holds up better to constant moisture than wood, and the slip-resistant textures available across all three brands work well on wet surfaces. For pool-specific projects, see our pool deck installation page for additional drainage and code considerations.
Do composite decks need to be sealed or stained?
No. The capped polymer surface is the sealing layer; sealants or stains would not bond to it and are not recommended by any of the manufacturers we install. Annual cleaning with water and a soft brush is the entire maintenance schedule.
What is the difference between a capped polymer and an uncapped composite?
Uncapped composite was the original generation of the material: a wood-polymer mix with no protective surface layer. Older, uncapped decks faded badly in UV and absorbed water. Modern capped composite has a hard polymer cap on the top and sides (or all four sides on premium lines) that resists UV, water, and stains. We only install capped composite boards. If you are evaluating a board and the datasheet does not specify “capped,” it is not the right product.
How long does composite deck installation take?
Typical residential build runs one to four weeks on-site once we start, depending on size, multi-level complexity, and weather. Lead time from contract signing to project start is two to six weeks, depending on material availability and seasonal demand. We provide a project-specific timeline as part of the written estimate.
What composite brand do you recommend?
It depends on the project. Full-sun west-facing decks and pool surrounds: TimberTech AZEK or Trex Transcend. Wood-grain visual priority: Fiberon Concordia. Budget-conscious shaded applications: Trex Enhance or Fiberon Sanctuary. We do not have a single brand we push; the right brand depends on what the deck needs to do and where it lives.
