Trex Deck Cost by State

Between $38 and $95 per square foot installed nationally, with a median around $52 for a mid-tier Transcend build. On a 16x20 deck — 320 square feet, the most common mid-size footprint — that is roughly $12,160 at the entry end and $30,400 at the top, with most projects landing near $16,600. The spread comes from the line rather than the labour: Enhance Basics at $35 per square foot and Signature at $75 are the same installation with very different boards on top. Then apply your state: material prices are close to national because Trex ships from regional distribution centres, but labour swings from about 0.92x the national average in the South to 1.28x on the West Coast, which moves a $16,000 project by several thousand dollars either way. Pick your state in the table below to apply the local multiplier.

Enhance if the budget is the constraint, Transcend if it is not, and Signature only for dark colours in strong sun. Enhance Naturals at $38 per square foot installed is a scalloped board, meaning it is hollow underneath — lighter, cheaper, and invisible once the deck is built, which is why it dominates Home Depot volume. Transcend at $52 is a solid board with deeper graining, and it is the line Trex's own railing systems are colour-matched to, so a Transcend deck with Transcend railing looks intentional in a way a mixed build does not. Signature at $75 carries the Lineage heat-mitigation cap, and that is worth paying for in exactly one situation: a dark colour on a deck with no shade. On a light colour or a shaded deck the premium buys almost nothing you will notice.

They win on different things, and the honest answer depends on which you value. TimberTech's AZEK lines are 100% PVC, which buys a 50-year structural warranty against Trex's 25, a surface that runs roughly 10 degrees cooler in the same colour, and no water absorption at all. Trex buys you a more authentic wood feel from its wood-fibre core, a broader palette at 27 colours against TimberTech's roughly 16, and the deepest retail availability in the country through Home Depot. Price sits close at the value tier — Trex Enhance at $38 per square foot installed against TimberTech Edge Prime+ at $42 — and separates at the top, where AZEK's PVC lines command $88 or more. If you are within five miles of saltwater or building in extreme heat, PVC has the technical edge. Otherwise the deciding factor is usually which retailer is closer.

Yes, like every composite, and colour matters far more than brand. Composite absorbs and holds heat more than wood does, and a dark board in full afternoon sun can become uncomfortable barefoot regardless of who made it. Trex's answer is the Lineage collection within the Signature line, which uses a heat-mitigation cap and is the only Trex product engineered specifically for this — it is available in four colours, so it constrains the palette. The alternatives are free: choose a lighter colour, which makes more difference than any cap technology; orient the deck or plan shade so the surface is not in direct sun at the hours you use it; or accept it and keep a rug in the seating zone. If heat is the primary concern and a dark colour is non-negotiable, PVC lines from AZEK run cooler than any capped composite including Lineage.

About 28 years in service, against a 25-year fade-and-stain warranty and a 25-year structural warranty — lifetime structural on the Transcend and Signature lines. That is roughly double a pressure-treated deck, which typically needs board replacement around year 18 and staining every two to three years in between. The warranty is transferable to the next owner, which is worth something at resale, but it has to be registered within 30 to 90 days of installation and it needs the board serial numbers. Those are printed on the boards and packaging, so ask the contractor for them on the day the decking goes down rather than after the offcuts are hauled away — an unregistered warranty is the most common way homeowners lose coverage they paid for.
