How to Choose a Deck

Thinking of a deck? Think ahead.

When it comes to building a deck, it’s worth thinking long-term. And that’s where this cheat sheet comes in. While some costs are simple, others cost you things more precious…like a lazy lunch with the kids, time with the newspaper, and straight-up patience. Below, we cover the five decision points to help you choose what’s right for you, your garden and your budget. (Not to mention your weekends.)

2. Labour

How Hard Is Installation?

The cost of building a deck can be 20-50% labour, so it’s important to consider whether or not this is a DIY project, or one best left to the pros.

Some of the hidden costs may surprise you, however. For instance, composites are as easy to handle as timber and usually require no special tools, while PVC is more difficult to customise.

3. Maintenance

How Much Upkeep Are We Talking?

Beyond the initial premium cost of composite decking, the cost of maintaining, replacing and simply hating the mess other products can turn into is worth a run through the calculator.

Often, in five to ten years time, the relative costs (think powerwashing, waterseal, stain, weekend-filling chores) even out.

4. Beauty

Lots Of Design Options?

Some materials enable customisable design options—everything from curves to multiple colours and timber grain patterns—while others are more limited in scope.

When choosing a material for your project, it’s helpful to keep your priorities in mind: are you looking for great design options, the best value, or maybe a product that offers a balance of both.

5. ROI

What's It Worth When I Move?

Some products add more value and joy to a home than others. The more carefree and eco-friendly the deck, the more attractive it is to potential home buyers…that is, if you can ever dream of moving.

6. Bushfire Resistance

Does it hold up to bushfire?

Think being in bushfire-prone zone prevents you from enjoying a deck? Think again. With Trex Transcend fireproof decking, you can enjoy the outdoors just like nature intended. This fire-retardant board has been tested and approved for BAL-19 and BAL-29 zones.
