What Are the Common Mistakes When Choosing WPC Decking?

Recently, a follower shared with me that the WPC decking they installed in their garden had completely cracked and fallen apart in less than five years. This left them puzzled and frustrated.

This issue is not uncommon in outdoor spaces. Many homeowners prioritize the quality of their garden lounge areas and have switched from traditional treated wood to WPC decking, thinking that any WPC decking will do, as long as it’s inexpensive. But is that really the case?

In fact, there are several common mistakes that people make when selecting WPC decking, and these mistakes can lead to significant problems down the line.

1. Material Selection

There are many manufacturers producing WPC decking today, and the quality can vary greatly. At first glance, most WPC decking may look similar, but how can you tell which one is good quality? It’s best to choose solid WPC decking rather than hollow ones, as solid boards are generally more durable. Additionally, if the decking contains PVC material, it likely has moisture trapped inside, which makes it prone to cracking. Be cautious of this when selecting materials. High-quality WPC decking includes a wear-resistant, UV-protective coating to withstand harsh outdoor conditions.

2. Joists

Never opt for wooden joists to save money, no matter how good the wood is—it will eventually rot beneath the decking. So, what type of joists should you use? It is highly recommended to use aluminum alloy joists. Some may argue that aluminum joists are too expensive, but consider this: aluminum joists come in complete kits that are easy to install. While galvanized steel pipes may be slightly cheaper, they require on-site welding with a welder, which can increase labor costs, making the overall expense comparable.

When choosing WPC decking, avoiding these two major pitfalls is crucial to ensure the longevity of your outdoor flooring. Be mindful of these points to avoid costly mistakes.
