Building or renovating a deck is an exciting journey that can transform your outdoor space, enhancing both its look and functionality. A frequent question among homeowners is whether you can lay composite decking over an existing wood deck instead of replacing the whole structure. In this blog post, we’ll dive into this topic, offering insights and tips to help you make the best decision for your home.
The Rise of Composite Decking
Composite decking has gained immense popularity in recent years due to its low maintenance, durability, and eco-friendliness. Unlike wood decks that require regular staining and sealing, composite boards are made from a blend of recycled plastic and wood fibers that require minimal upkeep. As such, it’s no surprise that many homeowners are considering converting their aging wooden decks into modern composite ones.
Composite Decking Over Existing Wood Frame: Is It Possible?
The short answer is yes; you can install composite decking over an existing wood framed deck. However, there are certain considerations to keep in mind before deciding if this option is right for you. For starters, the existing structure must be sound and in good condition. This means that the frame, posts, and joists must be free from rot, decay, or any other structural damage. If has been properly maintained over the years, this shouldn’t be an issue. However, if it’s showing signs of wear and tear, it might be a better idea to replace the entire structure instead of reusing it. Composite decking is estimated to last 25-50 years so building on an old structure that will only last 5-10 years would cut your investment short.
The Benefits of Composite Decking Over Existing Wood Framing
There are several advantages to installing composite decking over existing wood framing, making it a popular choice for homeowners. Here are some of the top benefits:
Time-efficient
If your existing deck is structurally sound and only needs cosmetic updates, installing composite decking over it can be a time-efficient option. You won’t have to tear down the entire structure and build a new one, which can be a time-consuming process.
Eco-friendly
Composite decking is crafted from recycled materials, positioning it as an eco-friendly alternative in the world of outdoor living spaces. It offers durability and low maintenance compared to traditional wood decking. This choice not only enhances the aesthetic appeal of your home but also plays a significant role in reducing your carbon footprint. By opting for these sustainable materials, you are actively contributing to the promotion of a greener, more sustainable environment.
Durable
Composite decking offers enhanced durability compared to traditional wood. It resists fading, staining, and scratching and is not prone to warping or rotting. This makes it an ideal choice for areas with harsh weather conditions or heavy foot traffic. Unlike wood, it does not require regular sealing or staining, saving both time and maintenance costs. This ensures a longer lifespan and maintains its appearance with minimal effort, providing a reliable and long-lasting decking solution.
Tips for Installing Composite Decking Over Wood Frame
When considering installing composite decking over your existing wood frame, several key tips can help ensure a successful project.
Existing Joist Spacing
Most composite decking requires joist spacing of 16” or less. If your existing wood frame has more than a 16” joist span, you will most likely need to rebuild the entire frame.
New Railings
When refacing a composite deck, it is always a good idea to replace the existing railings at the same time. Most low maintenance railing systems require special blocking between joists. Since the decking will be removed, this is the best time to install new railings.
Stair Framing
Since composite decking and fascia come in different thicknesses, it is always necessary to reframe the stairs of the deck. To safely have a rise and run that is within code, custom cut stringers are required.
Consider the Weight
Composite decking is significantly heavier than traditional wood decking, which means that adding it on top of an existing structure will increase its weight load. Before proceeding with the project, make sure your deck can handle this added weight without compromising its structural integrity. If you have any doubts, it’s best to consult with a deck professional or structural engineer for additional guidance.
Joist Tape
Specialized joist tape is a must for all re-deck applications. Joist tape provides an extra layer of protection over existing joists. Tape is installed on each joist before the deck boards are installed protecting moisture from penetrating the joists and causing rot.
Professional Installation
While it may seem like a simple and easy task to lay composite decking over wood, it’s always best to leave the job to professionals. They have the necessary tools, skills, and experience to ensure a smooth and successful installation. Plus, they can advise you on the best practices for maintaining your newly installed composite deck.
