Trex, TimberTech, or Budget Composite? An Alpharetta Buyer's Guide

Once an Alpharetta homeowner decides on composite over wood — a decision we cover fully in our composite vs. wood breakdown — the next question is almost always "okay, which composite?" The honest answer is that "composite decking" isn't one product; it's a spectrum from roughly $3 a square foot to well over $10, and the difference between tiers is real, not just marketing.

Capped vs. Uncapped: The Line That Matters Most

Before brand names, understand this split. Uncapped composite is a wood-plastic blend all the way through, which means it's exposed to staining and moisture absorption at the surface. Capped composite wraps that same core in a polymer shell that resists staining, fading, and mold far better — it's the reason capped boards carry longer warranties and hold their color through Georgia's pollen season and UV exposure without the surface degrading. Almost every composite board sold today at the mid-tier and above is capped; uncapped composite mostly shows up at the entry-level price point.

Entry Tier: Budget Composite and Trex Select/Enhance

At the low end, generic uncapped composite and Trex's Select and Enhance lines run roughly $3 to $6 per square foot for material. These boards perform reasonably well and cost meaningfully less than premium lines, but they typically carry shorter warranties — often 10 to 25 years versus 25-to-50-year coverage further up the lineup — and are more prone to visible fading or staining over a decade of Georgia summers. This tier makes sense for a rental property, a short-term hold, or a tight budget where getting composite at all matters more than getting the longest-lasting version of it.

Mid Tier: TimberTech Prime/Advanced and Fiberon

Stepping up, TimberTech's Prime and Advanced lines and Fiberon's core product range typically run $6 to $9 per square foot. This is where capped composite becomes standard, color and grain variation gets noticeably more realistic, and warranties usually extend to 25-plus years on fading and staining. For most Alpharetta homeowners planning to stay in their home for a decade or more but not chasing the absolute top shelf, this tier is the sweet spot — real durability improvements over entry-level without premium pricing.

Premium Tier: Trex Transcend and TimberTech AZEK/Reserve

At the top, Trex Transcend and TimberTech's AZEK and Reserve lines run roughly $9 to $15-plus per square foot. These boards use the most advanced capping technology, the widest color and finish selection, and typically carry the longest warranties in each manufacturer's lineup — often 50 years on fade and stain performance. For a forever-home deck, especially one that's a major backyard focal point or wraps a pool, this tier is where you're paying for the least maintenance and the longest color retention over the full life of the deck, which matters more the longer you plan to own the house.

Matching a Tier to Your Situation

• Rental or short-term hold: entry tier — the cost savings outweigh a longer warranty you won't be around to use.
• Mid-term homeowner (5–15 years): mid tier — the durability step-up pays for itself in appearance and fewer complaints from future buyers.
• Forever-home or resale-focused: premium tier — best long-term color retention and the strongest resale story to a buyer who asks what's underfoot.

Whichever tier fits your budget and timeline, the installation quality underneath it matters just as much as the board itself. See our composite and Trex decks page for how we build the structure that every one of these tiers sits on.
