Algae on composite decking

#1 · 14th October 2023, 7:50 pm

Next year we’re planning on having composite decking fitted in our courtyard. It’s in full shade and currently gets a lot of algae over the concrete that’s there, which we jet wash of the concrete in spring.

I don’t have any experience of composite decking and I’m wondering if the algae will stain it like it does on wood decking. Or will the jet wash clean it up fresh as new?

many thanks for your help

Hi @stevies_courtyard_garden
Good question about composite decking and staining. The quick answer is that algae won't stain this compared to wooden decking. This is because it's not porous, so the algae simply washes or even brushes off. That's the beauty of decent recycled composite decking with low maintenance garden designs. That and it won't rot!
For other Ninjas thinking of investing in composite decking vs wooden decking here are some pros and cons!
1.Composite Decking:
Pros of Composite Decking:
A) Low Maintenance: Composite decking is relatively low maintenance. It doesn't require regular staining or sealing and is resistant to rot, mould, and insects.
B) Durability: Composite decking is designed to withstand the elements, making it a long-lasting choice. It won't warp, crack, or splinter like wood can over time.
C) Colour and Style Options: Composite decking comes in a wide range of colours and styles, allowing you to find a look that matches your aesthetic preferences. All without needing to stain them each year!
D) Eco-Friendly Options: Some composite decking brands offer environmentally friendly products made from recycled materials.
E) Safety: Many composite boards have a textured surface that provides better traction, reducing the risk of slipping, especially in wet or icy conditions.
Cons of Composite Decking:
A) Initial Cost: Composite decking tends to be more expensive upfront compared to wooden decking. However, the long-term savings in maintenance costs can offset this.
B) Heat Retention: Some composite boards can become hot to the touch in direct sunlight, which might not be ideal for barefoot walking.
2.Wooden Decking:
Pros of Wooden Decking:
A) Natural Aesthetic: Wooden decking provides a warm and natural look that many find appealing. It can enhance the visual charm of your outdoor space.
B) Cost: Wooden decking is often more budget-friendly upfront compared to composite options.
C) Variety of Wood Types: Different wood species offer various colors and grain patterns, allowing you to choose a wood that suits your design preferences.
D) Easy to Work With: Wood is relatively easy to cut, shape, and install, making it a good choice for DIY projects.
Cons of wooden decking:
A) Regular Maintenance: Wooden decking requires regular maintenance, including staining or sealing to protect it from the elements. Neglecting maintenance can lead to rot, warping, and decay.
B) Durability: Wood is more susceptible to insect infestations, rot, and weather-related damage, which can reduce its lifespan.
C) Environmental Impact: Some wooden decking comes from unsustainable sources, leading to deforestation and negative environmental impacts.
D) Colour Fading: The colour of wooden decking can fade over time due to exposure to UV rays and weather conditions.
E) Splinters and Warping: Wood can splinter, and the boards can warp or crack, leading to safety hazards and a less attractive appearance.
The choice between the two materials depends on your priorities, style preferences, and long-term budget considerations.
Hope that helps?
