How to Keep Decking Safe in Winter: Your Complete Guide to Preventing Slips and Falls
Several factors combine to make decking particularly hazardous during winter:
Moisture and Ice: Rain, dew, and melting snow leave surfaces damp for extended periods. When temperatures drop below freezing, this moisture creates invisible ice layers that turn decking into a skating rink.
Algae and Moss Growth: Moisture and organic debris create perfect conditions for algae and moss to thrive. These organisms form a slimy film that becomes extremely slippery when wet, particularly on weathered wood.
Debris Build-up: Fallen leaves, twigs, and mud accumulate on decking, trapping moisture underneath and feeding algae growth. This combination creates additional slip hazards when ground into the surface by foot traffic.

How Do I Stop My Decking from Being Slippery?
1. Install Anti-Slip Decking Mats
Decking mats provide the most immediate and effective solution for creating safe walking surfaces. These specialised mats feature textured surfaces that deliver exceptional grip, whilst drainage holes allow water, debris, and snow to pass through freely.
Key Benefits:
- Immediate slip resistance without permanent installation
- Protect decking from foot traffic and weather damage
- Smooth out uneven surfaces where boards have lifted
- Easy to clean and maintain
- Wheelchair accessible with excellent wheel traction

2. Apply Decking Strips for Permanent Protection
Decking strips offer a permanent anti-slip solution that blends seamlessly with your decking. Made from glass-reinforced plastic (GRP), these strips are secured directly to decking boards using adhesive or screws.
Advantages:
- Low-profile design that’s less noticeable than mats
- Essential for stairs where loose mats aren’t safe
- Weather-resistant and long-lasting
- Available in colours to match your decking
3. Regular Cleaning and Maintenance
Prevention starts with keeping your decking clean:
Bi-Weekly Routine: Use a stiff brush to sweep away fallen leaves, twigs, and debris. Regular cleaning prevents algae and moss from establishing.
Seasonal Deep Clean: Before winter arrives, thoroughly clean your decking to remove any algae or fungal growth. Ensure gaps between boards remain clear so water can drain freely.
4. Apply Protective Treatments
Treating your decking with quality sealants creates a surface more resistant to water absorption and moss growth. Anti-slip deck oils contain compressed particles that create a rougher surface without cracking or peeling like paints.
Important: Apply treatments on dry, mild days in spring, summer, or autumn rather than during winter. The decking must be completely dry for proper penetration.
5. Safe Snow and Ice Removal
When winter weather strikes, proper removal techniques protect both safety and your decking:
Use Plastic Shovels: Remove snow with plastic rather than metal shovels to prevent surface damage. Shovel parallel to deck boards to avoid catching edges.
Choose the Right Ice Melt: Avoid traditional rock salt, which can stain and damage wood. Instead, opt for calcium chloride or magnesium chloride-based products, which are gentler on wooden surfaces. Sand or kitty litter provide immediate traction without chemicals.
What Is the Best Anti-Slip Solution for Decking?
For most homeowners, decking mats offer the optimal balance of effectiveness, ease of installation, and versatility. They provide immediate slip resistance without requiring permanent modifications and can be repositioned or removed as needed.
The complete range of decking mats at Trusted Mats includes options for every situation, from compact entrance mats to extensive interlocking tile systems.
How Can I Make My Decking Wheelchair Accessible in Winter?
Winter conditions create challenges for wheelchair users. Decking mats excel in this application:
- Rubber surfaces provide the traction wheels need on wet surfaces
- The smooth mat surface covers ridges and gaps between boards where wheels might catch
- Purpose designed options like the Rubber Ramp Mat are specifically suited for ramp applications
Do Decking Mats Damage Wooden Decking?
No, when used correctly, decking mats protect rather than damage wooden surfaces. The drainage design allows water and air to circulate beneath the mat, preventing moisture traps that cause rot.
Protection Benefits:
- Shield wood from direct foot traffic wear
- Prevent damage to finishes
- Extend overall decking lifespan
- Reduce UV weathering
Best Practice: Remove mats periodically to check the wood beneath and ensure proper drainage.
Choosing Between Decking Mats and Decking Strips
Choose Decking Mats When:
- You want immediate installation without tools
- You need flexible coverage for irregular spaces
- You prefer a removable solution
- You require maximum drainage capability
Choose Decking Strips When:
- You prefer a low-profile appearance
- You’re treating stairs where mats aren’t suitable
- You want a permanent solution
- Your decking has grooved boards ideal for strip installation
Many homeowners use both solutions together – strips on stairs with mats on larger flat areas.

Additional Winter Safety Tips
Pre-Winter Inspection: Check for loose boards, railings, and nails. Fix issues before winter weather worsens them.
Improve Lighting: Short winter days mean you’ll use your decking in low light. Install lighting where possible to improve visibility and reduce trip hazards.
Maintain Clear Routes: Keep primary walkways consistently clear of snow and ice to establish safe pathways.
