A season-by-season deck care calendar
Australian decks work hard. Strong UV, summer storms, humid coastal air and, in Sydney, long stretches of mild weather mean timber and composite boards rarely get a true rest. A simple rhythm across the year keeps a deck safer, better looking and longer lasting than an occasional big clean-up.
Spring: inspect and prepare
Spring is the natural time for a thorough check. Walk the deck slowly and look for raised nail or screw heads, split boards, soft spots and loose balustrade posts. Get underneath if you can and check that joists and bearers are dry and sound, and that nothing is resting against the timber that could trap moisture. Sweep out the gaps between boards, because packed leaves and soil hold water and encourage rot. If the finish looks patchy or water no longer beads on the surface, plan a re-coat before the heat arrives.
Summer: protect from sun and heat
UV breaks down oils and stains faster than most people expect, especially on north- and west-facing decks. Apply coatings early in the morning or late afternoon, never in full sun, and follow the product's drying times. Move pot plants regularly or raise them on feet so they don't leave rings. Keep barbecues on a heat-resistant mat and clear fallen gum leaves, whose tannins can stain lighter timbers.
Autumn: clean and clear drainage
As leaf fall peaks, sweep often and use a deck cleaner suited to your material to lift grime and mould before cooler, damper months. Check that gutters on any attached pergola or verandah roof are flowing and not dumping water onto the boards. Trim back shrubs so air can move around the deck.
Winter: watch for moisture
Shaded decks can turn slippery with algae in winter. A gentle scrub with an appropriate cleaner helps, but avoid high-pressure washing at close range, which can furrow softwood surfaces. Winter is also a good time to plan repairs; for structural concerns, ask a licensed builder or deck specialist rather than guessing.
Composite decks need less work but still benefit from regular cleaning and checks of fixings and subframes. For common questions about materials and approvals, see our FAQ.
