How Much Does a Trex Deck Cost in Louisville? (2026)

The cost of a Trex deck depends on the product line, the size and height of the deck, the railing style, and any add-ons like stairs, lighting, or under-deck drainage. Here's what Louisville homeowners actually invested in composite decks A&S Construction built in 2026.
What Composite Decks Cost in 2026
| Project Type | Typical Project Cost | Median |
|---|---|---|
| Composite Deck | $21,000 - $45,000 | About $31,000 |
| Composite Deck with Patio Cover | $47,000 - $78,000 | About $60,000 |
These ranges reflect the middle half of the composite deck projects A&S Construction sold in 2026. Smaller, simpler decks fall below the range, and large multi-level decks with premium railing, lighting, and under-deck systems fall above it.
How the Trex Line Affects Price
- Trex Enhance is the most budget-friendly Trex line and a great value for most decks.
- Trex Select is a step up in price, with a solid-board profile and a 35-year warranty.
- Trex Transcend and Transcend Lineage are premium lines with richer colors and a 50-year warranty. Lineage adds heat-mitigating technology.
- Trex Signature is Trex's luxury line and the highest price point.
For comparison, a pressure-treated wood deck of the same size generally costs noticeably less upfront but needs regular staining and sealing.
What Affects the Price
- Deck size. Smaller decks cost more per square foot because setup and fixed costs are spread over less area.
- Height. Second-story and elevated decks add framing, posts, and labor.
- Stairs. Each step adds cost, and multi-landing staircases add more.
- Railing. Upgrading from standard composite railing to aluminum, cable, or glass railing can add significantly. See our Trex Railing Options post.
- Under-deck drainage. Trex RainEscape adds cost based on the size of the deck, plus the cost of a finished ceiling below.
- Extras. Lighting, picture-frame borders, post wraps, skirting, and gates.
Example Project Budgets
- 300 sq. ft. ground-level Trex Enhance deck with standard railing: about $22,000 – $29,000
- 450 sq. ft. elevated Trex Transcend deck with aluminum railing: about $42,000 – $55,000
- Adding RainEscape and a finished ceiling below that 450 sq. ft. deck: about $13,000 – $17,000 more
Is Trex Worth the Cost?
Trex costs more upfront than wood, but it eliminates staining, sealing, and most repairs, and it's backed by a 25- to 50-year limited warranty depending on the line. When A&S installs eligible Trex products, your project is also registered for Trex's extended labor warranty through our TrexPro Platinum status. For homeowners planning to stay put, the long-term value is hard to beat.
