Aluminum vs Wood Decking: Waterproof Performance Comparison

Aluminum decking resists water. It does not corrode or absorb moisture. You can place it near oceans or pools, and it keeps its color and shine for years.

Wood decking absorbs water. Water penetrates the wood. Moisture causes swelling, cracking, and rotting over time.

Without sealing or treatment, damage to wood gets worse. The deck weakens and needs repairs earlier. Aluminum decking withstands seawater and wet conditions.

It suits docks, boats, and moist areas. Wood looks nice, but aluminum wins against water.

Cost Comparison and Long-Term Value

Aluminum decking costs $10 to $15 per square foot. The price changes based on the finish and thickness. Wood decking costs $5 to $12 per square foot.

Wood is cheaper to buy and install. However, wood needs regular maintenance. You must seal, stain, or replace boards as they wear out. These extra costs add up over time.

Aluminum decking needs less maintenance. Most aluminum decks do not need refinishing or replacement in the first five years. You pay more at the start, but you may spend less on repairs and upkeep later.

Wood saves money at first. Aluminum may save more in the long run.

Aluminum vs Wood Decking: Color Options and Design Flexibility

Aluminum decking offers many color choices. Manufacturers can powder coat, anodize, or treat aluminum boards in different colors. You can match aluminum decking to almost any outdoor style.

Wood decking gives fewer color options. The color depends on the wood type. You can stain or paint wood, but the range is limited.

Aluminum works well for modern designs that need specific colors. Wood keeps a natural look, but aluminum gives more freedom for color selection.

What is the Difference in the Installation Process?

Aluminum decking is simple to install. You attach the boards with screws. You do not need many extra fittings or complex framing.

Wood decking needs more steps. You must cut, fit, and secure each board. Wood decks use more fasteners and require extra support.

Aluminum saves time and effort during installation. Wood takes longer and needs more tools. Choose the option that matches your skills and schedule.
