When choosing the best decking material to suit your project, it helps to go through a few simple questions

What are you going to use your decking area for?

Consider the primary use of your decking space. Is it going to be a place for entertaining friends, al fresco family dinners, or a private area to escape the hustle of everyday life?

How exposed to the weather is the area going to be? 

Assess the deck’s potential exposure to natural elements. Will it get full sun, be under a patio or pergola, or sit next to a pool or water feature? Will the garden sprinklers spray the deck? 

How much time are you willing to put into keeping your deck looking great for years to come? 

Evaluate your availability for ongoing deck maintenance. If you live a busy life and don’t have the time to maintain oiling a timber deck, you might be better off going for a composite deck that requires less maintenance.

If you love the look of natural wood and don’t mind maintaining it from time to time, then timber decking is the perfect choice for you.

No matter what decision you come to, we’ve got the all the decking supplies you need to create an enjoyable, sustainable outdoor space. 

How do I calculate my quantities? 

If you have decided to install the deck yourself, we recommend you educate yourself on the product and the install process. By going through the exercise of working out your decking and sub-frame materials, it not only assists our team greatly in providing a fast turnaround on quotes, but helps to ensure you get the finished project you had hoped for.

For assistance with material calculations, we recommend using the online decking calculators provided by our trusted composite decking suppliers, linked below for your convenience.
