Trex vs TimberTech: Which Composite Deck Brand Is Worth It

Trex and TimberTech are the two dominant composite decking brands in Oregon, and homeowners researching either one usually want to know the same things: which one costs more, which one lasts longer in Pacific Northwest weather, and which one is worth the money for their specific project.

The short answer is that both brands make good products, but they are not interchangeable. Trex sits at a lower price point with a strong mid-range lineup and good color options. TimberTech runs more expensive but offers a true PVC product (the AZEK line) that handles wet PNW climates better than any capped composite on the market.

Craft Haven Carpentry installs both brands across the Willamette Valley and Portland metro. We have seen how each one performs over time in our climate, and this guide breaks down what we have learned: real cost ranges in Oregon, line-by-line comparisons, warranty differences, and which brand fits which type of project.

Quick Answer: Which Brand Is Right for You?

If you want the most decking for your budget and you are okay with a slightly shorter warranty, Trex is the right choice. If you live in a wet or shaded area, want the longest possible lifespan, or want a near-wood appearance, TimberTech (especially the AZEK PVC line) is worth the upgrade.

When Trex Makes More Sense

• You want a quality composite at the lowest price point in the category
• Your deck is in a relatively dry, sunny location
• You like a slightly more "composite" look (some of the texture is intentionally engineered)
• You want a wider selection of mid-range colors

When TimberTech Makes More Sense

• Your deck is in a wet, shaded, or moisture-heavy spot (think most of western Oregon)
• You want the longest available warranty and lifespan
• You want a deck that mimics real hardwood more closely
• You want a PVC option, not just a capped composite

Both brands hold up well in Oregon when installed correctly. The decision usually comes down to budget and how closely you want the deck to resemble natural wood.

Trex Decking: What You Need to Know

Trex is the largest composite decking manufacturer in North America. Their products are made from a mix of reclaimed wood fibers and recycled plastic, with a protective polymer cap on three or four sides depending on the line.

The Trex Product Lineup

Trex offers three main residential lines, each at a different price and feature level.

• Trex Enhance. The entry-level capped composite. Lighter weight, fewer color options, three-sided cap. Best for budget-conscious projects with shorter expected use.
• Trex Select. The mid-range option. Stronger color palette, four-sided cap (better protection), and a longer warranty than Enhance. This is the most common Trex installed in Oregon.
• Trex Transcend. The premium line. Deep, multi-tonal colors that mimic exotic hardwoods, the strongest scratch and stain resistance Trex offers, and a 50-year limited warranty.

Where Trex Performs Best

Trex performs well in standard residential settings: open backyards with normal drainage, sun exposure mixed with shade, and homeowners who want a low-maintenance deck without paying premium pricing.

In Oregon, Trex Select and Transcend both handle our climate well. The lower Enhance line is acceptable but tends to show wear faster in shaded, wet conditions.

Where Trex Has Limits

Trex is still a capped composite, not a PVC product. In persistently wet or heavily shaded locations, especially under tree canopy in coastal Oregon, capped composites of any brand can develop mold and mildew on the surface faster than PVC.

This is not a defect; it is just a material property. It washes off, but it can be a maintenance task you would not have with PVC.

TimberTech Decking: What You Need to Know

TimberTech is owned by AZEK, a company that has built its reputation on PVC building products. TimberTech offers both capped composite and full PVC decking, which is the key differentiator from Trex.

The TimberTech Product Lineup

TimberTech has two main product families, each with multiple lines.

• TimberTech EDGE. Capped polymer composite. The most accessible TimberTech line, competing directly with Trex Select and Enhance on price.
• TimberTech PRO. Capped composite with better color depth, four-sided cap, and a longer warranty.
• TimberTech AZEK. Full PVC decking. No wood fiber, no organic material. This is the premium line and the reason many homeowners choose TimberTech over Trex.
• TimberTech AZEK Vintage and Reserve. Multi-tonal, hardwood-inspired finishes that are among the most realistic composite options on the market.

Where TimberTech Performs Best

TimberTech AZEK (the PVC lines) is the strongest performer in wet and shaded environments. Because there is no wood fiber in the board, there is nothing for mold or moisture to attack from inside.

For Pacific Northwest homeowners with shaded yards, north-facing decks, or properties with heavy tree cover, AZEK PVC is often worth the price premium over any capped composite.

Where TimberTech Has Limits

TimberTech costs more across the board. The EDGE line competes with Trex on price, but most homeowners choose TimberTech specifically for the AZEK PVC products, which are noticeably more expensive than equivalent Trex lines.

PVC also expands and contracts more with temperature swings than capped composite. Installation has to account for this with proper gapping, which is why working with a contractor who knows the material matters.

Side-by-Side Cost Comparison in Oregon

Pricing varies by deck size, framing condition, and labor, but here are the realistic ranges for materials and full installation in Oregon as of 2025 and 2026.

Material Cost Per Square Foot (Board Only)

Total Project Cost in Oregon (Materials and Installation)

For a typical 300 square foot deck in Oregon, total project costs land in these ranges:

• Trex Enhance: $9,000 to $14,000
• Trex Select: $11,000 to $16,000
• Trex Transcend: $14,000 to $20,000
• TimberTech EDGE: $10,000 to $15,000
• TimberTech PRO: $14,000 to $20,000
• TimberTech AZEK: $17,000 to $28,000+

These ranges include substructure, railings, fasteners, permit fees, and labor. Larger decks, complex shapes, multi-level designs, and premium railing systems push costs higher.

What Drives Final Cost Up or Down

The biggest variables in your final number are deck size, height above grade, railing material, framing condition, and any structural work needed. For a deeper breakdown, see our guide on the cost to build a deck in Oregon.

If you want to spread the cost over time, we also offer financing options on most deck projects.

Performance in Pacific Northwest Weather

The Pacific Northwest is harder on outdoor surfaces than most US climates. Constant winter moisture, heavy shade in many backyards, freeze-thaw cycles in the Cascades and foothills, and humid spring conditions all stress decking materials.

Moisture and Mold Resistance

This is where the two brands differ most significantly.

Capped composites from both Trex and TimberTech resist moisture damage to the wood fibers inside the board. But the cap is what protects them. If the cap is compromised (deep scratches, damage at cut ends without sealing), moisture can reach the core.

TimberTech AZEK (PVC) does not have wood fiber at all. Moisture exposure is irrelevant to the structural integrity of the board.

Sun Exposure and Color Fade

All composite decking fades slightly over time. Both brands engineer their premium lines for stronger UV resistance.

Trex Transcend and TimberTech PRO/AZEK Vintage have similar fade resistance ratings. Entry-level lines (Enhance, EDGE) fade more visibly over 10 to 15 years, especially in lighter colors.

Heat Retention

Composite and PVC decks get hotter than wood in direct sunlight. Darker colors retain more heat. This matters for barefoot use during Oregon summers.

TimberTech AZEK runs slightly cooler than capped composites of similar color due to the material composition, but the difference is small. For sunny decks, lighter colors in either brand are a better choice if barefoot comfort is a priority.

Freeze-Thaw Performance

Both brands handle Oregon's mild freeze-thaw cycles without issue. Decks in higher elevations (Mount Hood corridor, Cascade foothills) see more aggressive cycling, and we still see good long-term performance from both brands in those environments when properly installed.

Warranty Comparison

Warranty terms are similar in length but differ in coverage detail. Here is what each brand actually guarantees.

Trex Warranty Coverage

• Trex Enhance: 25-year limited residential warranty on fade and stain, 25-year limited warranty on structural defects
• Trex Select: 25-year limited residential warranty
• Trex Transcend: 25-year limited warranty on structural, 25-year limited fade and stain warranty

TimberTech Warranty Coverage

• TimberTech EDGE: 25-year limited residential warranty
• TimberTech PRO: 30-year fade and stain limited warranty, 30-year limited product warranty
• TimberTech AZEK: Lifetime limited product warranty, 50-year limited fade and stain warranty

What the Warranties Actually Cover

Both brands cover structural failure (board breaking, splintering, rotting from the inside) and color fade beyond stated limits.

Neither covers normal wear, surface damage from impact, mold or mildew on the surface (a maintenance issue, not a product defect), or improper installation. This is why working with a contractor experienced with the specific brand matters.

For Pacific Northwest homeowners, the AZEK lifetime warranty is the standout feature on the TimberTech side. No capped composite from either brand offers equivalent long-term coverage.

Color, Style, and Aesthetic Options

Both brands offer wide color ranges, but their design philosophies differ.

Trex Color and Look

Trex colors lean toward engineered composite aesthetics: cleaner, more uniform color patterns with intentional grain variation. Transcend offers multi-tonal colors that mimic exotic hardwoods like Spiced Rum and Tiki Torch.

Trex offers a broader range of mid-priced color options than TimberTech in the same price tier.

TimberTech Color and Look

TimberTech, especially the AZEK Vintage and Reserve collections, focuses on hardwood realism. The color blends, grain patterns, and surface texture are designed to closely mimic species like cedar, mahogany, and weathered oak.

For homeowners who want a deck that looks like wood from a few feet away, TimberTech AZEK lines are typically the closest match on the market.

Picking the Right Color for Pacific Northwest Homes

Lighter colors stay cooler in direct sun, show less heat absorption, and tend to hide pollen, leaves, and the constant fine debris that comes with PNW backyards.

Darker colors hide stains better but show pollen and dust more, especially during spring. Most Oregon homes look best with mid-tone grays, weathered browns, or natural-looking blends that complement Pacific Northwest landscape colors.

Installation and Maintenance: What to Plan For

Both brands install differently than wood and differently from each other. Understanding what is involved helps you compare quotes and know what to expect after the deck is built.

Gapping and Fastening Differences

Capped composites (Trex and TimberTech EDGE/PRO) expand and contract less than full PVC. Standard composite gapping is around 1/8 inch between boards and 1/4 inch at butt joints, depending on the line and the temperature at install.

PVC (TimberTech AZEK) expands and contracts more with temperature swings. Installers have to gap more generously and use specific fastener systems designed for the material. Done wrong, PVC decks can buckle in the summer or open visible gaps in winter.

This is why working with a contractor experienced in the specific product matters. A great wood deck builder is not automatically a great PVC installer.

Routine Maintenance

Capped composite decks need a yearly wash with soap, water, and a soft brush to remove pollen, mildew spores, and general dirt. In the Pacific Northwest, north-facing sections may need an extra cleaning each spring to manage surface mold from winter shade.

PVC AZEK decks need less attention. A rinse with a hose handles most maintenance, and the material is more resistant to surface mildew. Many AZEK owners go years between deeper cleanings.

Neither brand requires staining, sealing, or refinishing. That is the main practical difference vs wood, and the biggest reason composite/PVC pays back its premium over a 10 to 20 year window.

Common Installation Mistakes to Avoid

A few mistakes show up repeatedly on composite deck failures we get called to inspect.

• Insufficient gapping at board ends. This is the most common cause of buckling, especially with PVC.
• Reused old framing under new boards. New composite over old, undersized, or rotted joists wastes the upgrade.
• Wrong fasteners for the system. Each line has approved fasteners. Generic deck screws can void the warranty.
• Skipped flashing at ledger boards. This causes water damage to the house, not the deck, but shows up years later as a much bigger problem.
• 
  

A quality install costs the same as a mediocre install at quote time. The difference shows up 10 years later.

Which Brand Is Worth It for Your Project

There is no single right answer, but the decision usually breaks down predictably based on three questions.

Question 1: How Much Sun and How Much Moisture?

If your deck is in a sunny, well-drained location, a quality capped composite from either brand will perform well. Trex Select or TimberTech PRO are both solid choices.

If your deck is shaded, north-facing, under tree cover, or on a property with heavy moisture, TimberTech AZEK PVC is worth the premium. The lifespan and maintenance difference shows up over 15 to 20 years.

Question 2: How Long Will You Own the Home?

If you are building a deck and planning to sell within 5 to 10 years, Trex Enhance or Select offer the strongest cost-to-curb-appeal ratio.

If this is your forever home, the lifetime AZEK warranty and PVC longevity often justifies the premium. You will likely replace a capped composite deck once in 30 years; you will not replace AZEK.

Question 3: Do You Want It to Look Like Wood?

If hardwood realism matters, TimberTech AZEK Vintage and Reserve lines deliver the closest match. Trex Transcend is good but reads slightly more as engineered composite up close.

For most homeowners and most yard styles, both look great. The "looks like wood" factor matters most for traditional, historic, or craftsman-style homes where authenticity is part of the design.
