For optimal protection, a deep clean and inspection should be done annually. Reapplication of a quality decking oil or sealer is typically recommended every 1-2 years, depending on your deck's exposure to sun, rain, and foot traffic. Harsh coastal environments may require more frequent maintenance.

We recommend using a dedicated deck cleaner or a mould and mildew removal solution. Apply according to the manufacturer's instructions, scrub with a stiff brush, and rinse thoroughly. For persistent growth, ensure your deck has adequate sunlight and airflow to prevent future issues.

While many oils are versatile, it’s best to select a product formulated for your specific timber. For example, hardwoods like Merbau or Spotted Gum often benefit from specialised hardwood oils that enhance their natural colour, while treated pine may require a different formulation.

Yes, but significantly less than timber. Composite decks should be cleaned 1-2 times per year with soapy water or a composite-specific cleaner to remove dirt and prevent biofilm buildup. They do not require sanding, staining, or sealing, making them a popular low-maintenance choice.

For minor cracks or splits in timber, use a quality timber filler designed for exterior use. For composite boards, consult the manufacturer’s warranty and repair guidelines. In both cases, addressing the issue early prevents further deterioration. We stock repair kits and can advise on the best solution for your deck type.
