Trex composite decking is the most requested decking material we install in San Antonio — and it’s not hard to understand why. No staining. No sealing. No splintering. A 25-year fade and stain warranty. And surface temperatures that run noticeably cooler than older composite products under direct Texas sun. Paradise Decks & Spas installs Trex composite decking across San Antonio and surrounding communities with the same fixed-price process and structural standards we bring to every project.

Trex composite decking is an excellent product. It’s also a product where installation quality directly determines whether the warranty stays valid and whether the deck performs the way it’s designed to. Trex has specific requirements for joist spacing, hidden fastener systems, board gap spacing for thermal expansion, and ventilation below the deck — requirements that vary by product line and that, when ignored, result in board cupping, fastener failure, and warranty disputes.
As an experienced Trex deck contractor in San Antonio with nearly two decades of composite decking installations, Paradise Decks & Spas installs every Trex product line to manufacturer specifications — because that’s the only way to deliver the performance Trex promises and the only way to keep the 25-year warranty intact.
Every Trex deck we build also starts with the structural framing that determines how the deck performs over its full lifespan — properly sized footings for San Antonio’s clay soil, pressure-treated framing throughout, galvanized hardware at every connection, and ledger flashing that keeps moisture away from your home’s structure. A premium surface material on a compromised frame is still a compromised deck.
Every decking material has a climate where it performs best. Trex performs exceptionally well in San Antonio for several specific reasons:
UV resistance. Trex boards use a protective polymer shell that resists UV degradation — the primary reason wood decks gray, crack, and require frequent refinishing in San Antonio’s high-sun environment. The fade warranty on Trex Transcend and Enhance lines covers color change beyond a defined threshold for 25 years.
Heat mitigation. Modern Trex products — particularly the Transcend line — incorporate heat-mitigation technology in the board’s polymer shell that reduces surface temperatures compared to earlier generation composite products. This matters in San Antonio where deck surface temperatures under direct afternoon sun can exceed 150°F on older dark composite boards. Trex’s current formulations run meaningfully cooler.
Moisture resistance. San Antonio’s occasional heavy rain events and pooling water concerns are handled by Trex’s capped composite construction — the polymer shell prevents moisture absorption that causes wood to swell, warp, and rot over time. This is especially relevant for pool-adjacent decks and any surface with regular water exposure.
No staining required. Wood decks in San Antonio need professional staining every 2–3 years to maintain protection. Trex requires only cleaning — soap, water, and a soft brush — with no staining or sealing ever. Over a 25-year lifespan, the maintenance savings are substantial.
Splinter-free surface. Pressure-treated pine splinters as it dries and ages in San Antonio’s heat. Trex’s composite construction remains splinter-free throughout its life — a meaningful consideration for families with children and pets using the deck barefoot.
Trex offers three primary decking collections — each with different performance levels, aesthetic options, and price points. Here’s an honest breakdown of each:
Trex Transcend is the flagship product line and the one we install most often for San Antonio homeowners who want the best long-term performance and the most realistic wood-grain appearance. Transcend features:
Transcend is the right choice for homeowners who want the premium composite experience — maximum heat mitigation, most realistic appearance, and the strongest warranty coverage.
Trex Enhance offers meaningful performance at a more accessible price point than Transcend. Enhance features:
Enhance is the right choice for homeowners who want the low-maintenance benefits of Trex composite decking at a budget point below Transcend without sacrificing the core warranty protection.
Trex Select is the entry point to the Trex product family — a solid-color, smooth-finish board that provides the core benefits of composite decking (no staining, no splintering, moisture resistance) at the most accessible price point in the Trex lineup.
Select is worth considering for utility deck applications — pool decks, maintenance-access platforms, or secondary deck areas — where performance matters more than premium aesthetics.
The most common question we get during Trex deck consultations: is composite really worth the higher upfront cost compared to pressure-treated wood? Here’s the honest comparison for San Antonio specifically:
Factor | Trex Composite | Pressure-Treated Pine |
Upfront material cost | Higher | Lower |
Staining/sealing | Never required | Every 2–3 years in San Antonio |
Splinter risk | None | Increases as wood dries and ages |
Fade resistance | 25-year warranty | Grays within 1–2 years without staining |
Moisture resistance | Excellent — capped composite shell | Moderate — requires consistent sealing |
Lifespan in San Antonio | 25–30 years with minimal maintenance | 15–20 years with consistent maintenance |
Surface temperature | Cooler than older composites — heat-mitigation tech | Varies by stain color; dark stains absorb significant heat |
Termite resistance | Resistant — composite is not a food source | Pressure-treated has chemical resistance but not immunity |
Total 25-year cost | Lower when maintenance costs are factored in | Higher when 8–10 staining cycles are included |
The upfront cost difference between Trex and pressure-treated pine is real — typically $8–$15 more per square foot installed. Over a 25-year lifespan, that gap narrows significantly when professional staining costs ($1,500–$3,000 every 2–3 years) are factored in. Most San Antonio homeowners who plan to stay in their home for 10+ years find Trex the more economical choice over the full ownership period.
Step 1 — Free On-Site Consultation We visit your property, evaluate the site, discuss your goals, and help you choose the right Trex product line and color for your home’s exterior and your usage goals. We bring physical Trex samples — all three lines, multiple colors — so the decision is based on real boards in your yard’s light conditions, not a website color swatch.
Step 2 — 3D Design & Fixed-Price Quote You receive a 3D rendering of your Trex deck, a written scope of work specifying the exact Trex product line and color, and a fixed-price quote. The number you approve is the number you pay.
Step 3 — Permits (Where Required) We prepare permit drawings, submit to the City of San Antonio Development Services or your local jurisdiction, and handle all inspection scheduling.
Step 4 — Structural Framing We build the pressure-treated subframe — footings, posts, beams, and joists — to the specifications required by Trex for the product line being installed. Joist spacing is set to Trex’s requirements for the specific board width and installation direction. Ledger board installation includes proper flashing on attached decks.
Step 5 — Trex Decking Installation We install Trex boards using the hidden fastener system appropriate for the product line — Trex’s proprietary Hideaway fasteners for Transcend and Enhance, or face-screwing with color-matched plugs where hidden fasteners aren’t applicable. Board gap spacing is set to Trex’s thermal expansion specifications for San Antonio’s temperature range. End cuts are sealed per manufacturer requirements.
Step 6 — Railing, Stairs & Finishing We install Trex railing systems, stairs, and any deck lighting, completing the project as a cohesive system rather than a surface dropped onto a subframe.
Step 7 — Final Inspection & Warranty Documentation We meet the city inspector on site, walk the finished deck with you, and submit Trex’s warranty registration so your 25-year coverage is on file from day one.

Trex Transcend is the top recommendation for San Antonio’s high-heat environment — it has the most advanced heat-mitigation technology in the Trex lineup, which keeps surface temperatures meaningfully lower than Enhance or Select under direct afternoon Texas sun. If budget is a consideration, Trex Enhance Naturals is a solid mid-range choice with good UV resistance and the 25-year fade warranty. We bring samples of all three lines to your consultation so you can compare them in person.
Trex Transcend is available in 12 colors spanning warm earth tones — Rope Swing, Tiki Torch, Spiced Rum, Havana Gold — and cool naturals — Island Mist, Gravel Path, Lava Rock, Clam Shell. Enhance and Select offer additional color options at their respective price points. San Antonio’s predominantly warm-toned stucco and brick exteriors tend to pair well with Transcend’s earth tone palette, though the right choice depends on your specific home exterior. We help you evaluate color options against your home during the free consultation.
Trex composite boards expand and contract with temperature changes more than wood — San Antonio’s wide temperature range between winter and summer means proper board gap spacing is critical. Trex also requires specific joist spacing (typically 12 inches on center for perpendicular installation, 12 inches for diagonal or picture frame) and hidden fastener systems that are different from standard wood deck screwing. End cuts must be sealed. Ventilation below the deck must meet Trex’s minimums. These requirements exist to prevent board cupping, fastener failure, and warranty disputes — all of which we follow on every installation.
All dark-colored surfaces absorb heat in direct sun — Trex is not immune to this. However, Trex Transcend’s current formulations use heat-mitigation technology that reduces surface temperatures compared to older composite products and compared to dark-stained wood. Lighter Trex colors (Island Mist, Gravel Path, Clam Shell) run cooler than darker tones (Lava Rock, Spiced Rum) for the same reason any light surface runs cooler than a dark one. We discuss color selection alongside heat performance during the consultation.
For most San Antonio homeowners planning to stay in their home for 10+ years, yes — when the full cost of ownership is considered. Pressure-treated pine requires professional staining every 2–3 years ($1,500–$3,000 per cycle), board replacement as UV damage accumulates, and ongoing maintenance attention. Trex requires cleaning only. Over 25 years, the total cost of a maintained wood deck often exceeds the total cost of a Trex deck installed at a higher upfront price. We walk through this comparison honestly during the consultation — including scenarios where pressure-treated is the more practical choice.
Trex’s 25-year limited warranty covers fade and stain performance — the structural warranty on the boards themselves is also 25 years residential. In practice, a properly installed Trex deck in San Antonio’s climate will easily reach and exceed 25 years with only cleaning maintenance. The subframe — pressure-treated lumber — has its own lifespan of 25–30 years with proper installation, so the deck system as a whole is designed for a multi-decade service life.
Yes. We submit Trex’s warranty registration on your behalf so your 25-year coverage is on file with Trex from day one of installation. This matters because warranty claims require proof of registration and proof of professional installation — both of which we provide.
