Decking Designed for Your Lifestyle
Tweed Heads sits right on the border between two states and two climates that share plenty in common, particularly when it comes to humidity, rainfall and coastal exposure affecting outdoor timber.

Our team is on hand to explain the practical differences between species, covering everything from colour and grain to expected maintenance over the years ahead. With a well-established network of stockists and agents, we're able to supply decking reliably for projects of any size, from a single residential deck to larger multi-unit developments.

Frequently Asked Questions
Is composite decking better than timber decking?
Composite decking and timber decking each have their own advantages, so which is 'better' really depends on priorities like appearance, maintenance and budget. Timber decking offers a natural look and feel that many homeowners prefer, along with the ability to be sanded and refinished over time, though it does require regular oiling or sealing to maintain its condition.
Composite decking generally requires less ongoing maintenance and can be more resistant to fading and splintering, but it often costs more upfront and can retain more heat in direct sunlight than natural timber. Ultimately, the right choice comes down to how much maintenance a homeowner is willing to commit to versus the natural aesthetic and characteristics timber provides.
How do you prevent mould and mildew on timber decking?
Preventing mould and mildew on timber decking largely comes down to managing moisture and ensuring adequate airflow both above and beneath the boards. Regularly sweeping away leaves, dirt and organic debris helps stop the buildup of the damp material that mould thrives on, particularly in shaded or poorly ventilated areas.
Applying a quality decking oil or sealant creates a protective barrier that reduces moisture absorption into the timber, making it harder for mould spores to take hold. In persistently damp or shaded areas, periodic cleaning with a timber-safe mould treatment, alongside trimming back overhanging vegetation to improve sunlight and airflow, can significantly reduce recurring issues.
What size joists are needed for timber decking?
The size of joists required for timber decking depends on factors including the span between supports, the spacing of the joists themselves and the species and thickness of the decking boards being used. As a general guide, joists are commonly sized at 90mm x 45mm or 140mm x 45mm, with larger dimensions used for longer spans or heavier expected loads.
Joist spacing typically ranges between 450mm and 600mm centres, with closer spacing required for thinner decking boards or areas expecting higher foot traffic. It's important to check span tables or consult a professional to ensure joist sizing meets structural requirements and relevant building standards for the specific project.
How do you stop timber decking from going grey?
Timber decking naturally turns grey over time due to prolonged UV exposure, breaking down the lignin in the wood's surface fibres, but this process can be slowed significantly with regular maintenance. Applying a UV-stabilised decking oil or stain on a consistent basis, generally every six to twelve months, helps protect the timber's natural colour and slows the greying process.
Choosing a product specifically formulated to block UV rays will generally offer better colour retention than a basic oil without added protection. If greying has already occurred, sanding back the affected surface layer and reapplying a protective finish can often restore much of the timber's original colour.
