Composite decks make sense in Austin for one reason most of all, the maintenance window. Pressure-treated pine wants a sand and re-stain every couple of summers under our UV. Capped composite and capped polymer skip that loop entirely. The cap is the finish. You clean it, you use it, and you spend your weekends actually on the deck instead of refinishing it. We install lines from well-known manufacturers including Trex, TimberTech, and Fiberon, paired with hidden fastener systems and a substructure sized for Texas heat cycles so the boards stay flat and gap-correct year after year. Every install is bid in writing, scheduled with a real timeline, and built with a crew that has put down a lot of composite in Hill Country sun.

Our Process

  1. Composite deck color and material choices shown alongside pavers and planters on a Lost-Pines project

    Material & Color Selection

    We start with physical samples on your deck site, not a brochure. You see capped composite and capped polymer (PVC) boards side by side in real Austin light, against your house color and existing hardscape. We talk through how sun exposure on your specific yard affects surface temperature, since darker colors run noticeably hotter in Texas afternoons. Then we narrow down to a product line and color that matches the way you actually use the space.

  2. Framing & Substructure

    Composite is only as straight and flat as the frame underneath it. We build a substructure of pressure-treated wood or steel framing for premium long-life installs, sized to the joist spacing your composite line actually requires. That usually means 16 inches on center for perpendicular boards and 12 inches on center for diagonal or 45-degree patterns. We flash the ledger to the house, set proper post footings, and pull permits where the City of Austin Development Services requires them.

  3. Composite deck boards with a clean surface beside a firepit and turf in Bee Cave

    Install With Hidden Fasteners

    Boards go down with a hidden fastener system so the surface stays clean and unbroken, no rows of exposed screws. We follow each manufacturer’s gap and expansion rules so the deck handles Austin heat cycles without buckling. Cut ends are sealed where required, and we keep gapping consistent across the entire field so the deck reads as one finished plane instead of a patchwork.

  4. Railings & Finish

    We finish with the railing system that fits the build, composite, aluminum, cable, or glass, plus stair treads, fascia, and skirting. The warranty paperwork is registered in your name, we walk you through care and cleaning, and we leave you with a deck that does not need staining or annual re-seal. You get a final punch-walk before sign-off so nothing gets missed.

Signs Composite Is Right for You

Capped Composite & Capped Polymer Decks

Composite is not the right answer for every Austin home. It is the right answer when you want the deck to disappear off your weekend task list and stay good-looking for 25 to 30 years under Hill Country sun. If any of the points below sound like you, capped composite or capped polymer is worth a serious look.

Request A Quote

  • Composite never needs staining and never needs annual re-seal. Soap, water, and a soft brush handle most cleaning. That is the trade for the higher upfront cost.

  • Premium capped composite and capped polymer lines come with long fade and stain warranties from major composite manufacturers, typically 25 to 30 years on the board itself.

  • Hidden fastener systems are the standard on composite installs. The surface reads as one continuous plane with consistent gapping and no field of screw heads.

Why Choose Thrive Landscape and Design?

  • Built For Texas Heat

    We size joist spacing, gapping, and color choice for Hill Country sun, so the deck stays flat, stays light enough to walk on, and holds its look.

  • Long-Life Substructure

    Pressure-treated wood framing on standard builds and steel framing on premium long-life installs, so the substructure outlasts the boards.

  • Hidden Fastener Standard

    Hidden fastener clips on every composite install. No exposed screw heads across the field, no patterned grid distracting from the boards.

  • Warranty Registered In Your Name

    We register the manufacturer fade and stain warranty in your name at install and hand you the documentation package so transfer at resale is straightforward.

FAQ

Frequently Asked Questions

  • Hot. Composite and capped polymer boards absorb solar radiation and a dark-colored deck in direct Austin sun can become uncomfortable barefoot during peak afternoon hours. Lighter colors and capped polymer (PVC) lines tend to stay friendlier underfoot than darker capped composites. We help you weigh the look you want against shade conditions, prevailing sun exposure, and how you actually use the deck, then we recommend a color family that matches the way Hill Country summers actually behave.

  • Yes. A capped composite or capped polymer deck never needs staining or annual re-sealing. The protective cap is the finish. Maintenance is limited to seasonal cleaning with soap, water, and a soft brush, plus an occasional rinse to clear pollen and oak tassels in spring. That is the trade you are buying with the higher upfront cost, you give back weekends that a wood deck would otherwise demand.

  • Capped composite has a wood-flour and recycled-plastic core wrapped in a polymer cap. Capped polymer (often called PVC) is solid polymer all the way through with a polymer cap. PVC is lighter, tends to stay cooler in direct sun, and resists moisture even at cut ends. Capped composite often looks and feels closer to real wood. Both come with long fade and stain warranties from major composite manufacturers. We walk you through samples so you can compare them in your hand.

  • For most Austin homeowners staying in the house long term, yes. A composite or capped polymer deck costs more on day one than pressure-treated pine, but it skips decades of staining, sealing, and board replacement. Fade and stain warranties on premium lines typically run 25 to 30 years. If you plan to keep the house and use the deck heavily, the math usually favors composite. If you plan to sell in a couple of years, wood may make more sense.

  • Most major composite manufacturer warranties are transferable to a subsequent homeowner, sometimes with a reduced remaining term. The exact rules vary by brand and product line, so we register the warranty in your name at install, give you the documentation package, and walk you through how to transfer it later. Lines from Trex, TimberTech, Fiberon, and other well-known manufacturers all publish their transfer terms in the warranty document.

  • Sometimes, but only after a full framing inspection. Composite boards require correct joist spacing, typically 16 inches on center for perpendicular installs and 12 inches on center for diagonal or 45-degree patterns. Older frames often do not meet that. We also check for rot, undersized beams, hardware corrosion, and ledger flashing at the house. If the substructure passes, we reuse it. If it does not, we rebuild it in pressure-treated wood or steel before any composite goes down.

  • Premium capped composite and capped polymer lines are engineered for very long service lives under UV exposure, and that holds up well under Hill Country sun when the deck is built correctly. Fade and stain warranties typically run 25 to 30 years on top-tier products. Real-world life often exceeds that when the substructure is sound, drainage is correct, and the boards have proper gapping for expansion and contraction in Austin heat cycles.

  • Call (512) 503-1935 or use the contact form on this page. We schedule a free on-site visit, measure the area, ask how you plan to use the deck, and bring physical samples of capped composite and capped polymer boards so you can see colors in your own light.
