Frequently Asked Questions

What timber do I need for decking?

Pressure-treated timber is one of the best options for decking frames because of its affordability.

How many deck boards do I need?

You'll need to calculate the area of the deck in m2 to figure out how many deck boards you'll need. To do this, multiply your deck's length by its width. For example: The length of your deck will be 5 metres, and the width will be 4 metres. 5 x 4 = 20, so the total area of your deck will be 20m2. Then you'll need to figure out how big a single board is. You must double the board's length by its width to achieve this. Finally, divide the deck's area by the area of the deck to figure how much decking you'll need to build your new deck.

What size wood for decking frame?

The most used joist sizes for decking are 2x6, 2x8, 2x10.

Do you need planning permission for decking?

You may need planning permission for decking if it covers more than fifty percent of your garden or is installed more than 30cm off the ground.

What is the best decking material?

Timber decking is affordable and traditional, while composite decking offers long-term durability with minimal maintenance.

How long does decking last?

Treated timber decking can last 10–15 years, while composite decking can last 20+ years.

Do I need treated timber for decking?

Yes, treated timber is recommended as it provides protection against moisture, rot, and insects.
