Winter-Proofing Your Deck: Tips for Keeping It Looking Great All Year

Winter can be tough on outdoor spaces, and your deck is no exception. Freezing temperatures, heavy rain, and even snow can take their toll, leading to damage, mould, and a slippery surface. But with the right care and restoration, your deck can stay in top shape all year round.

Whether you have a classic wooden deck or a low-maintenance composite one, these winter-proofing tips will help keep your outdoor space looking great and ready for spring.

1. Keep It Clean and Clear

Before winter sets in, give your deck a thorough clean. Leaves, dirt, and debris can trap moisture, leading to mould, mildew, and rot—especially on wooden decking.

How to clean your deck before winter:

• Sweep away leaves and debris regularly.
• Wash the surface with warm soapy water or a specialist decking cleaner.
• Remove any moss or algae to prevent slipperiness.

For composite decking, a simple wash with mild soap and water will do the trick. If this is a material you’re considering for your outdoor space, check out, the one-stop shop for all your decking needs.

2. Protect Wooden Decking with a Sealant

If you have a timber deck, sealing it before winter is essential. A good wood sealant or decking oil will help prevent water absorption, reducing the risk of cracks and warping in freezing weather.

Steps to seal your wooden deck:

• Ensure the deck is completely dry before applying any treatment.
• Choose a high-quality waterproof sealant.
• Apply evenly with a brush or roller, following the wood grain.
• Let it dry thoroughly before using the deck again.

Composite decking doesn’t need sealing, but a protective spray can help repel dirt and water.

3. Prevent Slips and Falls

Winter weather can make your deck dangerously slippery. Ice, frost, and wet leaves create hazardous conditions, so take steps to improve safety.

Ways to prevent a slippery deck:

• Use Anti-slip Decking Strips: Ideal for wooden decks prone to becoming slick.
• Lay Down Outdoor Rugs or Mats: Look for weather-resistant options for added grip.
• Sprinkle Sand or Cat litter on Icy Areas: Avoid rock salt, as it can damage wood and composite surfaces.

4. Check for Damage Before Winter Hits

Cracks, loose boards, or wobbly railings can worsen in cold weather, making repairs more difficult later. Before temperatures drop, inspect your deck and fix any minor issues.

What to look for:

• Rotting or soft spots in wooden decking.
• Loose screws or nails.
• Gaps or cracks that may expand with freezing temperatures.

Taking care of small repairs now can save you from bigger (and more expensive) problems come spring.

5. Cover or Store Your Garden Furniture

If you have outdoor furniture on your deck, protect it from winter’s harsh conditions. Either cover it with waterproof furniture covers or store it indoors to prevent damage.

For built-in seating on your deck, consider using weather-resistant cushions and covers to keep things in good condition.

6. Consider a Decking Cover or Awning

If your deck is exposed to heavy rain or snow, a temporary winter cover or awning can help protect it. While not essential, this extra layer of defence can reduce the amount of maintenance needed once spring arrives.

Will Composite Decking Start Creaking and Making a lot of Noise?

Have you ever walked on decking before and it starts creaking under your feet? When this noise happens, it can create the idea that the decking is old and unstable. This can happen to certain materials, and if you’re trying to create the perfect outdoor space, you probably want to avoid this from happening. So, is composite known to make a lot of noise and become creaky underfoot?

The answer is that it depends. While this can be a quieter material than others, such as PVC decking, it can start to creak as time goes by. This can be caused by several factors, which does mean that it can be avoidable. Let’s take a look at what those factors are.

1. The Board Quality

First, you need to pay attention to the composite decking boards you purchase. Not all companies are going to invest in quality. If you choose hollow and thin composite, this is more likely to creak and develop problems. However, if you make sure that you invest wisely in a reputable brand, you can get a better experience. Namely, premium and thick composite boards are less likely to make noise due to their strength and durability.

2. The Installation

You always want to ensure that you have the correct substructure and you’re installing composite decking securely. Otherwise, small mistakes can lead to creaking and other problems. Therefore, always plan your project in advance. You want to make sure the substructure is the best for your garden and you’re installing everything methodically.

3. Your Footwear

Don’t forget that it can be how you treat your composite decking and whether noise will occur. For example, if you’re constantly wearing heavy footwear and those that could damage the boards, this could lead to creaking and noise. Therefore, be mindful of what you’re wearing and how you’re spending time on your decking.

Final Thoughts

Winter-proofing your deck doesn’t have to be difficult. A little preparation before the cold weather hits can save you money, time, and hassle in the long run.

By keeping your deck clean, sealing wooden surfaces, preventing slips, and handling snow correctly, you can ensure your outdoor space stays in great condition all year round.
