What is Cheaper for Decking: Aluminum or Composite?

Introduction

When it comes to choosing the right material for a deck, two popular options are aluminum and composite decking. Both materials offer unique benefits and drawbacks in terms of cost, maintenance, and durability. This article delves into the initial installation costs, ongoing maintenance expenses, and long-term durability of aluminum versus composite decking. By examining expert opinions and real-world examples, we aim to provide you with a comprehensive understanding of which option might be more economical over time.

Initial Installation Costs

The initial cost of installing an aluminum deck is generally higher than that of a composite deck. Aluminum is a premium material known for its strength and lightweight properties, making it a bit pricier upfront. According to a study by HomeAdvisor, the average cost of aluminum decking can range from $25 to $40 per square foot, depending on factors such as quality, brand, and complexity of the design. On the other hand, composite decking typically falls between $15 and $30 per square foot, making it a more budget-friendly option initially.

Maintenance Expenses

Maintenance costs play a significant role in determining the overall affordability of a deck over time. Aluminum decks require minimal maintenance. They resist moisture, rot, and insect damage, which means they don’t need frequent resealing or staining. However, they may require occasional repainting if scratches occur. Composite decks also have low maintenance needs but may require periodic cleaning and occasional replacement of damaged boards. A report by Bob Vila suggests that while composite decks do not need painting, they might need replacement parts due to wear and tear, adding to the long-term cost.

Long-Term Durability

In terms of longevity, both materials have their advantages. Aluminum decks are highly durable and resistant to weather elements, offering a lifespan of up to 40 years with proper care. Composite decks, made from a blend of wood fibers and recycled plastic, are also durable, with a typical lifespan ranging from 20 to 30 years. However, composite decks may degrade faster under extreme weather conditions, such as prolonged exposure to sunlight or moisture. A study published in the Journal of Building Engineering found that while aluminum decks outlast composites in harsh environments, composites perform well in moderate climates with regular maintenance.

Expert Opinions and Real-World Examples

Experts weigh in differently on the cost-effectiveness of aluminum versus composite decking. According to the National Association of Home Builders (NAHB), aluminum decks are ideal for coastal areas due to their resistance to saltwater corrosion. However, the NAHB also notes that composite decks can be a better choice for homeowners looking for a natural wood look without the high maintenance requirements. Real-world examples show that while the initial investment in aluminum may be higher, its low maintenance needs and extended lifespan often make it a more economical choice over time.

Conclusion

Choosing between aluminum and composite decking depends largely on your specific needs and preferences. While aluminum decks tend to have higher initial costs but lower maintenance expenses and greater durability, composite decks offer a more affordable upfront option with manageable upkeep. Carefully considering these factors will help you determine which material is the most cost-effective for your deck project.
