A UK Homeowner's Guide to Replacing Wood Decking with Composite (2025)
Are you planning to build decking? If so, one of the decisions you have to make is to choose which material to use for your decking. Many homeowners prefer to use wood. Not only is it beautiful, but it is also affordable and easy to find. If you do chose wood decking, you still have to decide what variety of wood to use. When it comes to choosing decking materials, is cedar better than pressure-treated lumber?
What is Cedar?
Cedar is a type of softwood used for construction and decking. Softwoods come from fast-growing trees, making them some of the most affordable decking options. While not exactly the cheapest softwood variety, it is still less expensive than many wood options you can choose from.
Despite its low cost, Cedar offers many benefits when used for decking. It’s durable, naturally moisture-resistant and long-lasting. Due to its natural properties, it is resistant to insects and rot. It is also stable, making it resistant to warping, splitting, and bending. Cedar often comes in strong and dark-coloured shades, perfect for rustic and natural design aesthetics.
What is Pressure-Treated Wood?
Wood construction materials are susceptible to many forms of damage, such as moisture, insects, and decay. However, most high-quality wood is less prone to these issues. As for more common types of wood, chemical treatment is necessary for these wood varieties to be viable decking materials.
Pressure treated wood, often referred as PT wood, is a process performed on wood to protect it from moisture, insects, and weathering. Most types of woods can undergo pressure treatment, but it is more common in lower-quality lumber such as pine. Wood undergoes pressure treatment by infusing them with chemical preservatives that takes place in a large tank that punctures the wood, removes the air within the wood pieces, and replaces it with various chemicals.
Which One is Better?
To know which one is better between Cedar and pressure-treated wood, you will have to consider characteristics and traits and compare them with each other. Here are some that you may want to consider when deciding to choose Cedar or pressure treated wood.
Overall Performance
For homeowners on a budget, pressure-treated wood is better when it comes to costs. However, when it comes to overall performance, Cedar is the better option. It’s aesthetically pleasing and sustainable. While it does require care and maintenance, if done correctly, cedar is long-lasting and durable.
Other Options You Can Choose
Aside from Cedar and Pressure-treated wood, there are other options that you can choose from. For wood decking, you can opt for hardwoods such as oak, Ipe, and teak. While they are more expensive than softwoods, they are more durable, long-lasting, and require little maintenance.
There are also non-wood decking options such as PVC which offers superior durability and weather-proofing. However, older versions don’t look as natural as wood, but some of the latest versions of PVC decking being release into the market now, are increasing in authenticity.
You can also choose composite decking, which is as durable as PVC and offers many benefits over wood, including low maintenance, fade and stain resistance. In terms of appearance, Composite decking is more natural and mimics the beauty and aesthetics of wood, but you should expect to pay more for composite decking. Lastly, you can also choose aluminium decking. It’s not a common decking choice due to its high cost and engineered appearance but it is long-lasting.
