Trex vs TimberTech: Cost and Value Compared

Trex and TimberTech are the two names that show up on almost every composite deck quote in 2026. They're closer than the marketing suggests — both are capped, both carry long warranties, both cost roughly 2× pressure-treated. The real decision comes down to composite versus PVC, product tier, and what your local yard actually stocks.

Composite vs PVC: the actual fork in the road

Trex is wood-plastic composite (WPC) across its entire lineup: reclaimed wood flour plus recycled polyethylene, capped on three or four sides. TimberTech sells WPC too, but its Azek line is cellular PVC — no wood content at all.

• Weight: PVC boards are roughly 30–40% lighter, which matters on long spans and second-story decks.
• Heat: PVC and light colors stay cooler underfoot than dark WPC.
• Moisture: With zero wood content, PVC can't absorb water — the best choice for pool surrounds and humid coastal builds.
• Feel and look: Many builders think WPC reads more like real wood; PVC reads slightly more uniform.
• Price: PVC runs 15–25% more installed.

Warranty comparison

Both brands offer 25-year limited residential warranties on entry lines, rising to 30–50 years on premium and PVC products, and both include fade-and-stain coverage on capped boards. Read the fine print on labor: warranty coverage is almost always material-only, so a board replacement 12 years out still costs you a crew day.

Installation differences that affect your quote

Both brands support hidden fastener systems and both specify gapping for thermal expansion — but joist spacing rules differ by line. Several composite products require 12-inch on-center framing for 45-degree diagonal layouts and stair treads, versus the standard 16-inch. If your contractor quotes a diagonal pattern, confirm the framing is priced at 12 inches on center or you'll get bounce. Check spans first in the deck joist span chart and size the frame with the joist calculator.

20-year cost of ownership

On a 12×16 deck, pressure-treated costs about $4,300 installed but needs cleaning and sealing every two years — call it $250 a cycle, or $2,500 over 20 years, plus likely board replacement around year 15. A $9,000 composite deck needs a wash and a bucket of deck cleaner each spring, maybe $60 a year. Total 20-year outlay lands near $7,300 for wood versus $10,200 for composite — and the composite deck still has a decade of life left. The full math is in our composite vs wood comparison.

How to choose

1. Pool, coastal, or full-sun deck? Go PVC (Azek or Trex Signature), light color.
2. Tight budget but want composite? Trex Enhance Basics or TimberTech Prime.
3. Want the most wood-like look? Premium WPC — Transcend or TimberTech Legacy.
4. Whichever your local yard stocks deep. Availability beats brand loyalty; special orders add 2–6 weeks and freight.
