Choosing the right decking material is one of the most important decisions you’ll make when planning a new outdoor space. For homeowners in Sammamish, Redmond, Issaquah, Bellevue, and Mercer Island, the Pacific Northwest climate adds unique challenges: moisture, shade, temperature swings, and year‑round use.
Composite and PVC decking are the two most popular choices for long‑lasting, low‑maintenance decks. But in 2026, one material is clearly outperforming the rest — Azek Vintage Collection PVC.
At Endura Decking Co., we build with both composite and PVC, but when homeowners want the highest durability, lowest maintenance, and longest lifespan, we recommend Azek Vintage. Here’s why.
1. What Is Composite Decking?
Composite decking is made from a blend of recycled wood fibers and plastics. It’s capped with a protective shell that resists moisture, fading, and staining.
Why homeowners choose composite:
Natural wood‑like appearance
Excellent durability
Wide range of colors
Strong value for the price
Composite is a great choice for many homes — but it still contains wood fibers, which means it can absorb moisture over time, especially in shaded or damp PNW environments.
2. What Is PVC Decking?
PVC decking is made entirely from synthetic materials — no wood fibers. This makes it extremely resistant to moisture, mold, and temperature changes.
Why Azek Vintage Collection stands out:
Azek Vintage is the top‑tier PVC product on the market, offering:
The highest moisture resistance
Superior fade protection
Realistic wood grain and premium aesthetics
Lightweight strength
Minimal expansion and contraction
Cooler surface temperatures in direct sun
Azek Vintage is engineered specifically for long‑term performance in challenging climates — which is why it excels in the Pacific Northwest.
3. Durability in the PNW Climate
Composite Decking Durability
Composite performs well in the PNW, but because it contains wood fibers, it can be more susceptible to:
Moisture absorption
Mold growth in shaded areas
Expansion and contraction
Long‑term fading
Azek Vintage PVC Durability
Azek Vintage is fully synthetic, meaning:
Zero moisture absorption
No organic material to mold or rot
Superior fade resistance
Excellent performance in shade or full sun
Ideal for forested, lakefront, or damp properties
This is why we recommend Azek Vintage for Sammamish, Issaquah, and Snoqualmie homes with heavy shade or moisture.
4. Maintenance Requirements
Both materials are low‑maintenance, but PVC requires even less.
Composite Maintenance
Occasional cleaning
Rinse debris from gaps
Mild soap + water
Azek Vintage PVC Maintenance
Simple rinse
No organic material to absorb moisture
No risk of mold inside the board
Azek Vintage is the lowest‑maintenance decking material available.

A 20 to 35 year warranty
AZEK Vintage PVC Is Best For:
