A timber deck is one of the best additions you can make to a Western Australian home. It extends your living space outdoors, creates the perfect spot for entertaining, and adds genuine value to your property. But not all decking is created equal, and the choices you make at the start will decide whether your deck still looks great in ten years or starts warping, greying and splitting after a couple of summers.
As carpenters working across the Mandurah and Peel region, we get asked about decking more than almost anything else. Here is our practical guide to choosing the right timber decking for the WA climate, so you can make a confident decision before the first board goes down.
Why the WA climate changes everything
Our region throws a lot at outdoor timber. Long, hot summers dry boards out and can cause cheaper timber to crack. Coastal air between Baldivis and Bunbury carries salt that accelerates wear. Then winter brings damp that encourages movement and, if the timber is not looked after, rot. The right decking material is one that is chosen with these conditions in mind from the outset, not fitted first and worried about later.
Popular decking options for WA homes
There is no single best decking material, only the best choice for your budget, your home and how much upkeep you are prepared to do. Here are the options we most often recommend to clients across the Peel region.
Hardwood decking such as Jarrah, Merbau and Spotted Gum is a favourite for good reason. These dense Australian timbers are naturally durable, resist the elements well and develop a rich character over time. They cost more upfront and need occasional oiling, but they reward you with a premium look and a long life.
Treated pine is the budget-friendly option. It is widely available and easy to work with, which keeps costs down. Treated pine needs more regular maintenance to stay looking its best, but for many homeowners it is a sensible, affordable starting point.
Composite decking is worth considering if low maintenance is your priority. It will not splinter, warp or need oiling, though it does not offer the natural feel of real timber and comes at a higher price. For busy families who want to spend weekends relaxing rather than sanding, it can be a great fit.
Even the best timber will fail if the build underneath it is poor. Proper footings, correct joist spacing, adequate ventilation and quality fixings are what keep a deck solid and safe for decades. This is where the difference between a thorough carpenter and a cowboy really shows. A deck that is built right the first time saves you from costly rework, wobbly boards and premature rot. It is always cheaper to do it properly once than to fix a rushed job later.
Looking after your deck
A little maintenance goes a long way in our climate. Give the deck a clean each season to clear leaves and grime, re-oil timber boards once or twice a year to protect them from the sun and keep the colour rich, and check fixings and boards each year for any movement or wear. Catching small issues early keeps them from becoming expensive repairs down the track.
