Upgrading Your Deck: Can Composite Decking Be Added Over Wood?

Introduction to Composite Decking Over Existing Wood

Decking is a crucial part of any outdoor living space, providing a comfortable area for relaxation and entertainment. However, over time, wood decks can deteriorate due to exposure to the elements, leading many homeowners to consider upgrading their deck with composite materials. One common question that arises is whether it’s possible to add composite decking directly over an existing wood deck. This article explores this possibility, examining the benefits of composite decking, practical considerations, and potential drawbacks.

Advantages of Composite Decking

Composite decking offers several advantages over traditional wood, particularly in terms of durability and maintenance. According to a study by the University of Wisconsin-Madison, composite materials are more resistant to rot, insects, and moisture compared to wood (source). Additionally, composite decking requires minimal upkeep, requiring only occasional cleaning and no staining or sealing. This makes it an attractive option for those looking to minimize ongoing maintenance costs and efforts.

Practical Considerations

While composite decking provides numerous benefits, there are several practical considerations to keep in mind when contemplating adding composite decking over an existing wood deck. First, the weight of composite materials is significantly higher than wood, which may necessitate structural reinforcement of the existing deck framework. Secondly, installing composite decking over wood might not be feasible if the current deck has significant damage or uneven surfaces, as this could compromise the integrity and appearance of the new deck. In such cases, it might be more prudent to remove the old deck entirely before installing the new composite one.

Potential Drawbacks

Despite its many advantages, adding composite decking over wood also comes with potential drawbacks. The cost of composite materials is typically higher than wood, which can make the project more expensive upfront. Furthermore, while composite decking is generally more durable, it is not indestructible; scratches and dents can still occur, though they are less likely than with wood. Lastly, the installation process for composite decking is more complex and often requires specialized tools and expertise, which can increase labor costs.

Conclusion

Adding composite decking over an existing wood deck is possible but involves careful consideration of various factors. While composite materials offer enhanced durability and lower maintenance needs, the added weight and potential need for structural reinforcement must be taken into account. For homeowners looking to upgrade their deck, consulting with professionals and thoroughly assessing the condition of the existing structure can help determine the best course of action.
