Composite decking comes in grades, usually sold as good, better, and best, and every major brand (Trex, TimberTech, Fiberon, and Deckorators) offers lines at each level. Every grade skips the staining and sealing a wood deck needs. What you pay for as you move up is a tougher protective shell, solid instead of scalloped boards, more realistic wood grain and color, better scratch and fade resistance, sometimes heat-mitigating technology, and a longer warranty, typically climbing from 25 years at the entry level to 50 years or more at the top. The grade you choose matters more than the brand name, and for most Louisville families a mid-range or premium line is the sweet spot.
Walk into any decking showroom and the same brand will offer boards at very different prices that look similar from across the room. The difference is in the details you live with every day: how the surface holds up to grills, chair legs, and dogs; how hot it gets in a July afternoon; how real it looks up close; and how long the manufacturer stands behind it. Here's what each grade gets you, so you can choose with confidence.
All modern composite decking has a core, usually a blend of wood fiber and plastic, wrapped in a protective outer shell, often called a cap. As you move up in grade, a few things change:
Clean, simple look and zero staining, at the best price. A great upgrade from wood for a budget-conscious project.
Richer color, more character, and a longer warranty. The best value for most families.
Realistic hardwood looks, tough scratch resistance, cooler options, and the longest warranties.
The most realistic grain and most durable surface available, for a true showpiece deck.
We install all four major composite brands, and we're not tied to any one of them. Here's how each brand's lineup steps up. Product names and warranty terms change from time to time, so we'll confirm the current details for any line you're considering during your estimate.
| Trex Line | Grade | What Sets It Apart | Limited Residential Warranty |
|---|---|---|---|
| Enhance (Basics & Naturals) | Good | Scalloped profile, Trex's lightest composite boards; heat-mitigating option in select colors | 25 years |
| Select | Better | Monochromatic and multi-tonal colors, enhanced mold and mildew resistance, can be curved | 35 years |
| Transcend | Best | Exotic-wood-inspired grain and rich colors, highly resistant to scuffs and scratches, can be curved | 50 years |
| Transcend Lineage | Best | Refined linear grain plus heat-mitigating technology; Trex calls it its coolest decking yet | 50 years |
| Signature | Luxury | Photorealistic woodgrain; Trex's most durable and most scratch-resistant board | 50 years |
Trex's entry-level Enhance is a genuinely good product and a big step up from wood maintenance-wise, but its warranty is half as long as the top lines. Transcend Lineage stands out for decks in full afternoon sun because of its heat-mitigating technology.
| Fiberon Line | Position in Lineup | Performance Warranty | Stain & Fade Warranty |
|---|---|---|---|
| Good Life Weekender | Entry | 25 years | 25 years |
| Good Life Escapes | Step-up | 30 years | 30 years |
| Sanctuary | Upper | 40 years | 40 years |
| Concordia | Top | Lifetime | 50 years |
Fiberon's warranties climb steadily with each step, and its top Concordia line carries a lifetime performance warranty, the longest in this comparison.
| Deckorators Line | Material | Structural Warranty | Stain & Fade Warranty |
|---|---|---|---|
| Venture, Vista | Traditional composite | 25 years | 25 years |
| Summit | Mineral-based composite | 25 years | 25 years |
| Voyage | Mineral-based composite | 50 years | 25 years |
Deckorators is the one brand here that offers a mineral-based composite, made with its Surestone technology, alongside traditional wood-and-plastic composites.
TimberTech's entry collections, such as Prime+, use boards capped on three sides with a 25-year fade and stain warranty. Its higher collections step up to more realistic finishes, four-sided capping, and longer warranty coverage.
There isn't a single best brand. Trex, TimberTech, Fiberon, and Deckorators all make solid, low-maintenance decking, and each offers entry, mid-range, and premium lines. A premium board from one brand will outperform an entry board from another, so the grade you choose matters more than the logo on the box.
The better question is which specific line fits your deck. Compare lines at the same price level on what actually matters to you: the warranty, the colors and grain you like, heat performance if your deck sits in full sun, and whether matching railing and trim are available in the look you want. Because we install all four brands, we can put comparable lines from different manufacturers side by side and recommend what fits your project, not what fits a single brand's sales goals.
Alongside composite, several of the brands we install also make cellular PVC decking, such as Trex Refuge and TimberTech's AZEK collections. Both are low-maintenance and never need staining. The difference is what's inside the board: composite blends wood fiber with plastic, while cellular PVC is all plastic with no wood content at all.
| Composite | Cellular PVC | |
|---|---|---|
| What it's made of | Wood fiber and plastic, with a protective shell | 100% plastic, no wood fiber |
| Moisture, mold & rot | Very resistant thanks to the shell, but the core contains wood | Can't absorb water or support rot |
| Weight | Heavier, more solid feel underfoot | Noticeably lighter |
| Expansion with heat | Moves less with temperature swings | Expands and contracts more, so installation has to allow for it |
| Heat in direct sun | Varies by product and color | Varies by product and color |
| Cost | Generally lower | Generally higher |
Choose cellular PVC if your deck is around a pool, in a damp or heavily shaded spot, or anywhere moisture is the biggest concern, or if you want the most moisture-proof board available. Choose composite if you want the best value, a heavier and more wood-like feel, and less seasonal movement in the boards. Both are excellent choices that will outlast and outperform a wood deck on maintenance. Because PVC moves more with Louisville's summer heat, it should be installed by a crew that spaces and fastens it to the manufacturer's requirements, which is exactly what we do.
Often, yes. A deck is something you'll use for decades, and the extra cost of a premium board buys a surface that resists scratches and fading, looks better up close, and comes with a warranty up to twice as long as the entry level. Premium heat-mitigating lines are especially worth it for decks in full Louisville summer sun.
A composite deck also holds its value well. According to the Remodeling 2025 Cost vs. Value Report (www.costvsvalue.com), a composite deck in Louisville recoups about 90% of its cost at resale. For more on how outdoor projects add value, see do decks, screen porches, and sunrooms add value to your home.
If you plan to sell soon or the deck won't see much use, an entry-level line is a perfectly sensible way to save. It still never needs staining.
Composite deck installation in Louisville typically runs $45 to $75 per square foot installed, including framing, decking, and railing. The grade of decking you choose is one of the biggest factors in where your project lands in that range, along with size, height, railing, and stairs. We'll price out more than one grade side by side so you can see exactly what the upgrade costs on your deck.
Pick your grade based on where the deck sits and how you'll use it, not just the sticker price. A deck in full afternoon sun with a dog and a grill on it is a very different job from a shaded deck you use a few evenings a month. We visit every home in person before any project, so we can look at your sun exposure and use and recommend the grade that fits.
