Building a new deck is an exciting prospect for any homeowner, but one of the most critical decisions you’ll face is selecting the right timber.
With a myriad of options available, it can be overwhelming to determine what timber is best for a new deck. You want something to suit your needs, budget, and aesthetic preferences. At Deking Decks, we understand the importance of choosing the perfect timber for your new deck.
Let’s explore the various factors to consider when selecting timber and provide guidance to help you make an informed decision that will result in a beautiful and durable deck for years to come.
Why is timber choice important for new decks?
When selecting timber for your new deck, it’s essential to choose a species that offers durability and longevity, especially in Brisbane’s climate. Consider the natural resistance of different timber species to factors such as moisture, rot, insects, and UV exposure.
Another crucial factor to consider is the maintenance requirements of the timber. Some species may require regular sealing or staining to maintain their appearance and protect against weathering, while others may be more low-maintenance.
The visual appeal of the timber is also an important consideration. Consider the architectural style of your home, surrounding landscape, and personal preferences when choosing a timber that complements your design aesthetic.
For eco-conscious homeowners, considering the environmental impact of the timber is paramount. Look for timber that is sustainably sourced and certified by reputable forestry organisations.
Finally, consider your budget and the cost of the timber. While some species may be more affordable upfront, they may require more frequent maintenance or have a shorter lifespan, leading to higher long-term costs.

The best timber for a pool deck is a Class 1 or Class 2 durable hardwood, such as Spotted Gum or Merbau. These species have a high natural density, resisting rot, termites, and moisture swelling.
The biggest mistake people make when choosing timber is focusing solely on day-one aesthetics rather than long-term durability. Outdoors, timber must withstand severe moisture, movement, and weather fluctuations over time.
Premium hardwoods like Spotted Gum, Blackbutt, and Merbau generally add the most value. Class 1 and Class 2 durable timbers offer high density, exceptional resistance to decay and termites, and a luxurious aesthetic that appeals to buyers.
