This guide will walk you through the most popular options, their pros and cons, and key factors to consider so you can make an informed decision.
By the end, you’ll understand the differences between wood, composite, and other materials, and you’ll have practical tips for picking the one that fits your needs. You’ll also get insights on cost considerations and maintenance requirements, so there are no surprises down the road.
Wood Decking Options
Wood has been the classic choice for decks for decades. It offers a natural look and feels warm underfoot. However, not all wood is created equal, and understanding the types can save you frustration.
This is the most common and budget-friendly wood Fence Installation. Pressure-treated boards are chemically treated to resist rot, decay, and insects. They work well in wet climates like the Pacific Northwest, but they can warp or crack over time. Staining or sealing every few years helps prolong their life.
These species are naturally resistant to rot and insects, making them ideal for areas that see a lot of rain or humidity. Cedar and redwood age to a beautiful silver-gray if left untreated, giving a deck a classic look. They cost more than pressure-treated lumber but require less chemical treatment.
Ipe, teak, and mahogany are dense, long-lasting woods that can last 25-50 years with minimal maintenance. They resist scratches, mold, and rot, but are heavy and more challenging to work with. These woods are often the choice for homeowners who want a premium, high-end deck. For more detailed information about these woods, you can check on Wikipedia.
Pro Tip: When choosing wood, inspect boards for knots, cracks, and warping. Even high-quality wood can have weak spots that reduce its lifespan.
Composite and Synthetic Materials
Composite decking has surged in popularity over the last decade. It combines wood fibers with recycled plastic, giving you the look of wood without the intensive upkeep.
Composite boards resist rot, splintering, and insect damage. Unlike natural wood, they don’t need staining or sealing, and occasional washing keeps them looking fresh low-maintenance vinyl fencing. Some premium brands even offer fade-resistant finishes, which are perfect for decks exposed to lots of sun.
Composite decks come in various colors, textures, and finishes. Some boards mimic the grain of natural wood closely, making them almost indistinguishable from real timber. This versatility allows you to match your deck with your home’s style effortlessly.
Because many composites use recycled materials, they can be more environmentally friendly than traditional lumber. However, they aren’t biodegradable, so consider their long-term lifecycle.
Pro Tip: Choose a composite brand that offers a warranty covering fading and staining. In my experience, cheaper composites can discolor in just a few years.
Aluminum and PVC Decking
For homeowners looking for something truly low-maintenance, metal and PVC decks are worth considering.
Aluminum is lightweight, strong, and completely resistant to rot and insect damage. It’s often used in modern deck designs and can support longer spans without extra support posts. Aluminum decks can be more expensive initially, but often last a lifetime.
100% PVC boards are plastic and don’t contain wood fibers. They’re impervious to moisture, insects, and fading. They’re extremely low-maintenance, just occasional washing, and are available in a wide range of colors. However, they can feel hotter underfoot in summer compared with wood or composite choosing between different fencing and decking options.
Pro Tip: In rainy areas like Auburn, WA, PVC or aluminum decks can reduce the risk of mold and slippery surfaces during wet months.

| PVC | 25–40 years | Very low | High | Smooth, modern colors | No rot, low-maintenance | Can be hot underfoot, plastic feel |
| Aluminum | 50+ years | Very low | High | Sleek, modern | Extremely durable, lightweight | Limited natural wood look |
Pre-Decision Considerations for Your Deck
