    A timber deck

    Canberra Timber Decking Services

    Nothing compares to the look and feel of timber, and if you’re looking for a decking option that will last the ages, then timber is your best choice.

    Additionally, timber decks will not warp or rot like composite decking, so it is perfect for those looking for a decking material that will last.

    Timber decks also give your home an attractive, natural look. They are often much more affordable than other options such as composite or steel, which is why they have become trendy in Canberra, ACT, over the past decade.

    At Guaranteed Building, we aim to offer the best timber decking and accessories in Canberra, ACT. That is why our team of contractors is on hand to discuss your options and requirements.

    Timber decking is the best option for families with kids that love playing outside as they are less likely than other materials to splinter, which can be a hazard for small children.

    Merbau Decking by Guaranteed Building

    One of the most popular types of timber decking in Canberra, ACT, is Merbau. A natural brown colour and grain pattern that mimics the grey appearance of weathered wood provides an attractive look to your outdoor space.

    If you are in a hot climate, Merbau is a good choice as it does not splinter or become brittle in the sun. Merbau decking boards provide an exciting contrast to natural-looking timber such as Cedar and Western Red Cedar, which have a yellowish hue.

    Let’s dig into some of the advantages of Merbau, shall we?

    • The grain of the wood is appealing, and it gains a beautiful dark patina over time, making it very appelly to homeowners.
    • It doesn’t require any treatment or sealing because it is naturally resistant to rot and decay. Cheap maintenance.
    • This timber has no knots, leading to less splinters as they will not come loose with time as quickly as oter materials.
    • It is a dense hardwood that resists warping when installed and can also be installed over concrete slabs or directly on the earth. 
    • Unlike most other decking products, there is no need for sealant, which requires a barrier to prevent moisture from getting through.
    • Merbau has excellent soundproofing properties, making it a perfect choice for people who live in urban areas with noise pollution.
    • Wood is not only aesthetically pleasing but has the added benefit of being able to be recycled and reused over and over again.

    With these advantages, it is hard not to see why Merbau decking should be your first choice. We offer high quality, durable and beautiful decking at an affordable price.
