TREX Decks
TREX Composite Deck Building in West Jordan, UT
Composite decking on framing built to the right joist spacing — because the boards carry a 25-year warranty and the frame underneath is what actually fails first.

Composite decking outlives the frame it sits on. Which is why we spend the money under the boards, where nobody looks.
TREX and similar composites solved the real problem with wood decks in Utah: our UV load and dry-heat cycling are brutal on stained lumber, and a wood deck here needs attention every two or three years to not look weathered. Composite gives you a 25-year board with a wash-down as the maintenance plan.
What that hides is that the deck's lifespan usually comes down to the substructure. Composite boards are heavier and less stiff than lumber, so joist spacing has to be tighter — and a frame built to generic wood-deck spacing will feel bouncy on day one and sag long before the boards give out.
The parts of a deck estimate worth comparing line for line:
It's worth asking honestly, because for a lot of West Jordan homes a concrete patio is the better buy. Decks make sense when there's a grade change to span — a walkout basement, a slope falling away from the back door, or a door that sits well above finish grade. If your back door is close to grade and the yard is flat, a patio delivers the same usable space for meaningfully less money and lasts longer than any decking.
Where a deck genuinely wins, composite is the material we recommend over wood in this climate almost without exception. And on split-level and walkout lots, a deck plus a patio underneath is the layout that gets used most — shade below, sun above.
