The Dangers of Installing Composite Decking Over Wood Decks: A Comprehensive Guide
Many homeowners seek to enhance their outdoor living spaces with innovative materials like composite decking. However, installing composite decking over an existing wood deck can pose significant long-term risks. In this article, we will explore the dangers of this common mistake, discuss the importance of proper installation, and provide valuable advice for maintaining your deck.
Understanding the Risks of Installing Composite Decking Over Wood
Installing composite decking over wood decking can lead to moisture retention between the two layers. This moisture can cause the wood underneath to rot over time. The efficiency and cost-effectiveness of composite materials become nullified when structural damage results from neglecting the underlying wood.
What Happens When Composite Decking Is Installed Over Wood?
When composite decking is placed over wood decking, the two layers inevitably create a sealed environment. This environment traps moisture and debris, leading to moisture retention. The wood underneath, with its compromised integrity, becomes predisposed to rot and mildew, potentially necessitating extensive repairs or replacements.
The Importance of Removing Old Wood Decking
It is strongly recommended to remove the old wood decking before installing composite deck material. This step is essential for ensuring long-lasting and stable performance. Without thorough removal, the wood can continue to hold water and deteriorate, ultimately leading to faster decay and necessitating replacement of both materials.
Types of Decking Materials: A Closer Look at Wood and Composite Decking
Wooden Decking
Wooden decking offers a natural, timeless aesthetic. It provides comfort underfoot and a warm, inviting ambiance. Wood comes in various types and price ranges, with some exotic woods ensuring durability but often at a higher cost. While wood can last for decades with proper care, cheaper options may only survive 10-15 years before requiring significant maintenance.
Composite Decking
Composite decking is an innovative solution made from a blend of plastic and recycled wood fibers. This material is designed to be moisture-resistant and splinter-free, with built-in UV protection. Composite decks are easier to maintain and more environmentally friendly since they can be made with recycled materials. Despite these advantages, they come at a higher price point compared to traditional wood and offer a slightly different texture and appearance.
Choosing Between Wood and Composite Decking
Selecting between wood and composite decking is a matter of balancing aesthetics, budget, and maintenance needs. Wood provides a classic, warm look and can last longer with proper care. Composite materials are low-maintenance and offer durability, but they are more expensive and may not mimic the natural beauty of real wood.
