Is Your Decking Ready for Autumn and Winter? Why Now Is the Time to Act

Autumn and winter bring wet leaves, frost, persistent rain, low light, algae, and moss. Even if the warmer months have passed, a dry day is a good opportunity to inspect your decking and deal with problems before conditions worsen.

Preparing the surface while it is clean and dry can be easier than trying to fix a problem during a cold, wet spell.

Why Autumn and Winter Need Extra Attention

• Wet leaves can form a slippery layer on decking.
• Frost and ice can make smooth or contaminated surfaces hazardous.
• Persistent rain can keep boards wet for long periods.
• Low light can make steps and edges harder to see.
• Algae and moss can build up in cool, damp conditions.

Prepare Your Decking Before the Wetter Months

Choose a dry day to inspect and clean your decking. Repair loose or damaged boards first, then check steps, ramps, and shaded areas where grip may be a concern. If you are fitting anti-slip strips, follow the product instructions and make sure the boards are suitable and dry before installation. Keep clearing leaves and cleaning the surface through autumn and winter.

GreenTec® GRP anti-slip decking strips screw onto suitable existing boards. Choose the width and spacing for the substrate, expected use, and site conditions, and follow the product installation guidance.

Which Areas Need Attention First?

• Steps and stair edges
• Shaded or north-facing sections
• Ramps and sloped areas
• Routes between the house, garden, shed, or gate
• Areas with frequent foot traffic

For steps and stair edges, GRP stair nosing can add a defined grip area and make the edge easier to see when correctly selected and installed.

Simple Checks Before Winter

• Does the decking feel slippery when wet or dewy?
• Are leaves, algae, or moss building up?
• Are any boards loose, rotten, or damaged?
• Do steps or ramps need better edge visibility?
• Are lighting and handrails suitable for the route?

Repair unstable boards before fitting anti-slip products. Keep the surface clear and continue regular cleaning after installation.

Don’t Wait Until It Becomes a Problem

If the decking is slippery when wet, has shaded areas where algae builds up, or includes steps used by visitors, prepare it before the colder, wetter season arrives.
