Trex Transcend Calculator

$55-85 per square foot installed depending on color collection + pattern + complexity. A 16×20 (320 sqft) Transcend Earth Tones deck with Trex Transcend Railing and 4 stairs lands around $24,000 nationally; the same deck in Lineage with Trex Signature aluminum rail and DeckLighting lands around $34,000. Multiply by ~0.92× South or ~1.28× West Coast. Calculator outputs a project-low to project-high range.

For most homeowners, yes — Transcend has the broader palette (14 colors vs Select's 5), the multi-tonal cap that looks more like real hardwood, and the heat-mitigation Lineage option for hot climates. The materials premium is about $0.90/lf (Transcend $5.40 vs Select $4.50), which on a 320 sqft deck is roughly $290 more. The aesthetic upgrade typically justifies the small premium. Select is the right pick when budget is the priority OR you want a monotone modern look.

Lineage (launched 2024) is Trex's heat-mitigation Transcend variant — a new cap formula engineered to reflect more of the sun's near-infrared spectrum. Dark Lineage colors stay about 35°F cooler at the surface than equivalent dark Transcend colors. Particularly valuable in hot climates (Phoenix, Las Vegas, Dallas) or for barefoot decks. The premium is about 9% per LF ($5.90 vs $5.40). The four colors (Rainier, Carmel, Biscayne, Jasper) are all mid-to-cool tones — there's no Lineage Lava Rock equivalent yet (the darkest colors would still run warm even with the technology).

TUHF (Trex Universal Hidden Fastener) is Trex's clip system for grooved boards. Each box ships 90 clips and covers ~50 sqft at 16″ joist on-center. Box price is $89; loose clips $1.25 each. The clip nests into the board's edge groove and screws into the joist, leaving a screw-free surface. Compared to AZEK CONCEALoc (90/$85/50 sqft), TUHF is roughly equivalent price and coverage. MoistureShield CoolClip (180/$132/90 sqft) is the highest per-sqft coverage available.

No — Transcend (like every Trex line and every wood-fiber composite) is rated for 16″ joist on-center maximum perpendicular to the boards under AWC DCA-6. The only composite line with a 24″ OC rating is Deckorators Voyage + Vault (mineral-based composite, DCA-6 exception). For Trex installs over older 24″ OC framing, you'll need to add sister joists every 8 ft to bring effective spacing to 16″ OC. The calculator's BoM doesn't include those sister joists since they're an existing-framing remediation cost.

Trex RainEscape is an under-deck drainage system — a sloped EPDM membrane installed between the joists, with downspouts at the perimeter. It turns the space below a raised deck into a dry, finished patio area protected from drips through the deck boards. Adds about $4.50/sqft installed. Useful if you have a walkout basement or want covered storage under the deck. Best installed during the deck build, not retrofitted later.

Lava Rock is Transcend's darkest color — a near-black hue that absorbs more solar radiation than any other shade in the line. In 90°F full sun, Lava Rock surface temperatures can hit 170-180°F (uncomfortable barefoot). The calculator flags a heat warning when you pick a Heat-Rating-1 color on a deck below 60″ above grade (where bare feet are most common). For a barefoot-friendly dark deck, switch to Lineage Carmel or Biscayne — same dark visual character, 35°F cooler.

Once you set length × width + pattern + fastener + stairs, the calculator prices the exact same deck across all 3 Transcend sub-collections (Tropicals / Earth Tones / Lineage) using each collection's per-LF retail. The side-by-side table shows total range + per-sqft for each. Tap any to switch the calc to that sub-collection; the color picker resets to that collection's first color. Fastest way to see the Lineage heat-mitigation premium on your specific deck.

Yes — Trex Transcend (all 3 sub-collections) carries a 25-year limited residential structural warranty AND a 25-year limited residential fade & stain warranty. Transferable one-time to a future homeowner at no charge. Register at trex.com/warranty within 30 days of install for full coverage. AZEK Vintage/Harvest/Landmark (50-yr structural / 30-yr fade) and MoistureShield Meridian (lifetime / 50-yr) have longer warranties if that's a priority for you.
