As temperatures drop and rainfall increases, decking can take a fair amount of wear. Whether your garden uses timber or composite boards, preparing for winter helps extend its lifespan and keeps it safe underfoot. This guide explains essential decking maintenance winter checks, how to protect wooden decking, and what to look for with composite decking care.
Why Winter Preparation Matters
Timber and composite boards both react to moisture, frost and falling debris. Without proper upkeep, wooden decking can become slippery or start to rot, while composite boards may accumulate grime that dulls their appearance. Winter maintenance avoids long-term damage and preserves the strength of the sub-frame beneath the boards.
Key Steps to Protect Wooden Decking
- Clear debris regularly
Leaves, moss and dirt trap moisture against the timber. Sweeping the surface weekly during wet months helps prevent decay and slippery patches. - Wash the boards before the cold sets in
A gentle scrub with warm water and mild detergent lifts built-up dirt. Avoid harsh chemicals that strip protective coatings. - Apply a suitable treatment
Oils, stains or sealants designed for outdoor timber provide weather resistance. Winter rain is frequent, so applying treatment in early autumn gives it time to set. - Inspect for rot or loose fixings
Check joists, screws and visible edges. Addressing small issues early prevents larger structural problems later.
Composite Decking Care in Winter
Composite boards require less upkeep but aren’t fully maintenance-free.
- Clean with warm water and a soft brush to remove algae or surface residues.
- Avoid pressure washers on high power as they can damage textured surfaces.
- Check gaps between boards and clear out trapped debris to maintain drainage.
Good composite decking care ensures the surface remains slip-resistant and presentable throughout the colder months.
Safety Considerations Through Winter
Wet and icy conditions can make any decking unsafe. Anti-slip strips or mats help in high-traffic spots. For ice, avoid rock salt, which can harm both timber and composite materials; warm water or specialist de-icing products are safer options.

Ongoing Care Throughout the Season
- Keep gutters and nearby branches clear so water doesn’t pool around the deck.
- Lift and store garden furniture if possible to avoid staining or warping the surface.
- Ventilate the area below raised decking to prevent damp.
- Carry out a mid-winter check after heavy storms to make sure the surface is draining properly.
Maintaining decking through winter doesn’t require major work, but consistency pays off. A few simple steps – combined with timely treatment for timber and routine cleaning for composite – help keep your garden space safe and durable all year round.
