Best Composite Decking Manufacturer and Why
When homeowners ask us which composite decking brand is best, the answer depends on what you value most—appearance, longevity, or budget. As a Seattle deck builder with more than 25 years in residential construction, Petra Decks has worked with every major brand out there. Three names consistently rise to the top: Trex, TimberTech & Azek
Let’s compare what makes them stand out and which might be the right fit for your project.
1. Trex Decking – Best Overall Value
Trex is the most recognized name in composite decking—and for good reason. It offers a wide range of options from affordable to premium, all built around a solid track record of performance.
Why we recommend Trex:
Durability: The capped composite surface resists fading, scratching, and mold.
Value: Excellent balance between cost and longevity.
Warranty: 25-year limited residential warranty on most lines.
Sustainability: Made from 95% recycled materials, including reclaimed wood and plastic film.
Trex also integrates well with its Trex Signature railing and RainEscape waterproofing systems, which makes it a versatile choice for Seattle homeowners upgrading both deck boards and under-deck space.
Best for: Homeowners who want reliable performance and proven brand quality without overpaying.
2. TimberTech – Best for Design and Realistic Wood Look
TimberTech (by AZEK Building Products) offers composite and PVC options known for rich texture and color depth. Their TimberTech Pro and Edge lines feature composite cores, while TimberTech Azek is full PVC for maximum moisture resistance.
Why we recommend TimberTech:
Aesthetics: Their woodgrain texture and color realism are unmatched.
Variety: Multiple lines at different price points.
Moisture Resistance: Excellent for the Pacific Northwest’s damp conditions.
Warranty: 30–50-year fade and stain coverage depending on the product line.
Best for: Homeowners who prioritize appearance and want their composite deck to closely mimic real wood.
3. Azek PVC Decking – Best for Ultimate Longevity
Azek (also part of the TimberTech brand family) is made entirely from PVC, not composite. That makes it virtually impervious to moisture, mold, and mildew—an ideal choice for Seattle’s wet climate.
Why we recommend Azek:
Zero Wood Content: No risk of rot or splitting.
Cooler Surface: Reflects more heat than darker composites.
Lightweight and Stable: Won’t warp or swell.
Warranty: 50-year limited fade and stain warranty.
While Azek costs more upfront, it pays off in minimal maintenance and exceptional durability—especially for homes near water or in shaded, damp yards like Snoqualmie and Issaquah.
Best for: Homeowners who want the longest-lasting, lowest-maintenance deck possible.
Our Professional Take
At Petra Decks, we’ve installed all three systems for clients across West Seattle, Kent, and Sammamish, and each has a clear niche.
Trex: Best for balanced performance and cost.
TimberTech: Best for authentic wood appearance.
Azek: Best for ultimate longevity and moisture resistance.
The right choice depends on your goals, home style, and budget.
