Seasonal Deck Maintenance Tips: Keep Your Deck Safe Year-Round

A deck is a major investment, but without care, it can turn into a slippery, rotting liability. From spring cleaning to winter protection, here is your quarterly guide to keeping your timber or composite deck in top condition.

A beautiful deck is the centrepiece of a summer garden. But here in Bristol, the damp climate can be brutal on timber. If left unchecked, that stunning golden wood can quickly turn into a grey, slippery hazard.

At Joe's Fencing & Landscaping, we believe that little and often is the key to longevity. You don't need to spend days scrubbing; just follow this simple seasonal rhythm to keep your deck safe and looking brand new.

Spring: The Deep Clean (March – May)

After a wet winter, your deck is likely covered in grime, moss, and early signs of algae. Now is the time to reset.

  • The Wash Down: Use a stiff broom and a dedicated deck cleaner to scrub away the winter dirt. Warning: Be very careful with pressure washers. If you use a high-powered jet too close to the wood, you can "fur up" the fibres, ruining the smooth finish and actually making it rot faster. Use a wide fan setting and keep your distance.
  • Tighten Up: Wood expands and contracts. Check for any loose boards or popped screws that might have worked their way up during the freeze-thaw cycles. Countersink them back down to save your bare feet in summer.

Summer: Protection & Inspection (June – August)

While you are enjoying the BBQ season, the sun is your deck's biggest enemy. UV rays break down the lignin in the wood, causing it to grey and crack.

  • The Splash Test: Pour a cup of water on the boards. If it beads up, your protection is fine. If it soaks in immediately, the wood is thirsty.
  • Oil It: Apply a high-quality UV decking oil. Unlike paint (which sits on top and flakes), oil soaks in and nourishes the timber, preventing it from drying out and splitting in the heat.

Autumn: The Anti-Slip Offensive (September – November)

This is the most critical time for safety. Wet leaves combined with morning dew create a slime layer that is as slippery as ice.

  • Leaf Clearance: Don't let leaves sit in the corners or between the gaps. Wet leaves trap moisture against the wood, accelerating rot. Sweep them off regularly.
  • Pot Watch: If you have heavy plant pots on the deck, lift them up on "pot feet." If they sit directly on the wood all winter, you will find a perfect black ring of rot underneath them come spring.

Winter: Damage Limitation (December – February)

When the frost hits, the goal is simply to avoid causing damage.

  • No Rock Salt: Never use grit or rock salt on a timber deck. It dries out the natural moisture in the wood and can corrode the metal fixings/screws.
  • Plastic Shovels Only: If we get snow, clear it with a plastic shovel or a broom. A metal shovel will gouge the surface, destroying the seal you applied in summer.

Composite Decks Need Love Too

If you have a composite deck, you get off lightly, but you aren't completely off the hook. You still need to sweep away leaves to prevent mould growth in the shade, and give it a wash with soapy water to keep the colour vibrant.
