Composite Decking: The Best Outdoor Decking For Winter

For most of the year, your outdoor deck is a great place to hold parties, cook, and enjoy crossovers outside. But that may not be the case in the winter. In snowy and very cold places, an outdoor deck may not be usable. In addition, snow and ice, which are common in winter, can damage your deck. This article introduces you to the best decking for winter—high-quality and cheapest composite decking. Which is better adapted to the environment, lasts longer, and is easier to care for than traditional wood decking.

What Kind of Decking Is Best for Winter?

If you live in a place with a lot of rain and cold, you might be wondering which type of decking lasts the longest under those conditions. Composite decking is made to handle the cold, dampness, and UV rays that are frequent in the winter. It doesn’t need much winter prep and won’t expand, crack, rot, or soften when it gets wet, snowy, or icy.

COOWIN capped composite decking is a strong, elegant, and affordable option for homeowners who care about both looks and performance. It comes in a range of natural hues and textures that look like wood, grass, or stone. Custom choices let you make designs that work with all boards.

Even though composite is better in many ways, it’s still a good idea to compare it to wood to get the whole picture:

Composite is more durable but costs more up front. Over time, decreased maintenance costs can make up for the initial cost. For example, maintaining wood may cost more than $1,000 a year. But maintaining the composite may only cost $200.

Why Does Composite Decking Hold Up Well in Winter?

Composite decking combines wood fibers with high-density recycled polyethylene, often capped with a polymer layer for enhanced protection. COOWIN’s capped version offers superior weather resistance, making it stronger than pure wood or plastic. It’s ideal for long-term use with minimal repairs.

In addition to environmental resilience, composite decking has other advantages, offering greater performance than other materials do in winter.

Easy to install

Composite decking is easy to install, which makes them perfect for busy homeowners. To install composite decking boards, you just need to follow these steps:

• Select a flat, stable surface (not directly on grass or sand). Use an existing framework if it sounds good.
• Build a foundation with joists spaced per guidelines (typically 12–16 inches on center).
• Acclimate boards for 48 hours.
• Plan your design, using clips for secure fastening.
• Add end caps or fascia, sealing cuts with waterproof sealant.

Moisture Resistance

Composite decking is highly resistant to water because it is made of plastic. This is helpful in the winter when mud, frost, and snow piles typically stay on your deck for a long time. With composite decking, you don’t have to worry about water getting in and rotting or warping the wood. Composite deck boards will also dry quickly once the snow melts and it gets warm. The shorter the time it takes for the water to freeze again, the faster it dries.

Anti-mold and Anti-deterioration

COOWIN composite decking has a protective layer that prevents mold and mildew from entering the core of the decking. Over time, mold can destroy traditional decking. With our capped composite decking, you’ll never have to worry about your deck boards breaking.

Not Prone to Warping, Breaking, or Splitting

Unlike uncapped composite decking, capped composite decking has a polymer coating on all four sides, which makes it better at protecting your decking boards. Even if your composite wood decking is regularly exposed to UV rays or harsh weather, our fully capped decking will keep the surface from cracking, warping, or splintering. This will make your outdoor decking last longer and keep you comfortable when you’re outside.

Stability

Humidity and moisture cause all wood decks to grow and shrink over time. composite wood decking is stable in all types of weather and temperatures. Compared to traditional decking, composite wood decking is less likely to grow, shrink, or move over time.

Easy to Maintain

Composite decking requires little to no maintenance. It’s made in such a way that it won’t need to be repaired or replaced for decades. However, there are things you can do to get the most out of your composite wood decking and get better results.

Durability

Your composite decking won’t lose its color or finish due to snow, sun, or high or low temperatures, so you can rest assured that your deck will look as good as new when spring comes.

Thanks to a special protective polymer coating, the color of your deck won’t change much over time. Therefore, you don’t need to stain, sand, or oil composite decking anymore.

How to Prepare Your Outdoor Deck for Winter

Although composite decking is strong and durable, there are some steps you should take to prepare for cold weather in order to better bring out its value.

Check your outdoor deck

Before winter arrives, inspect your outdoor deck to identify any areas that need attention.

• Deck railings. Check all parts of the deck railing, inspecting your railing from top to bottom, including each post. Winter weather can cause a lot of damage to wooden railings, so it’s important to find weak posts now.
• Stairs. If your composite decking has wooden stairs, you must take the right steps to prepare them for winter. This means sealing them up with something that won’t let water in before it snows or rains, and if possible, covering them.
• Tiles on the deck. Look at each board or tile for any problems such as standing water, stains, or other things that need to be fixed before winter.
• Cracks and spaces. Make sure there is nothing in the cracks and spaces between the deck boards, railings, and stairs.
• Foundations. Make sure there are no weak links in the foundation or deck supports, such as holes, cork, cracks, or other damage.
• Joists. Make sure all wood joists are intact and that all screws or nails are tight.

If you see any weak spots on your outdoor deck, you should fix them before winter arrives, as cold weather can make weak spots worse.

Preparing Your Outdoor Deck

Once you’ve checked your deck and fixed anything that needs fixing, it’s time to get ready for winter. To do this you need to do a few things to prepare.

• Remove furniture and decorations. Remove all carpeting, deck furniture, planters, trellises, lighting, or other decorations that are not waterproof.
• Clean your deck. The cleaner your deck is, the easier it will be to survive the cold winter months. Use mild soapy water to clean your deck. Don’t forget to clear any cracks in your deck and remove any debris that has built up.
• Use a sealer. Sealers add a layer of protection from water damage to any weak spots. After you’ve cleaned your outdoor deck and allowed it to dry completely, apply the sealer to it.

Snow Removal

Use an outdoor broom to gently move the snow instead of a shovel. This is the best way to keep your deck in good condition. If there is too much snow, or if you need to make a path outside your house, chances are you will need to shovel. When you have to shovel snow, follow these precautions:

• Use a shovel made of plastic. Metal shovels can scratch or scrape your deck boards, so be sure not to shovel snow with a metal shovel.
• When using a plastic shovel or broom to remove snow, keep it parallel to the deck to avoid damaging it.
• When ice forms on the deck surface, do not use a shovel to break up or split the ice. Instead, use a gentle, even motion to shovel it up.
• Choose an ice melter. If possible, use ice melt on the porch rather than a shovel. Do not use sand or ice melt products containing sand, as these particles can scratch your deck or get stuck in the spaces between decks. Use a de-icer that is safe to use on composite decking.

Looking for Breakage After Winter

After winter, it’s time to inspect your outdoor deck again. Do a visual inspection of your entire deck again and make a note of any changes that need to be repaired. If you repaired some parts of your deck before winter, check to see if they are still in good condition or if more work needs to be done.

Here are some signs of possible surface damage:

• Noise or bouncing when you walk on the deck
• Rusted or broken nails and screws
• Sagging or cracked joists
• Bent, loose, or shifting railings
• Wooden stairs that creak or make you feel like you’re sinking when you walk on them.

If you notice any of these problems, you should call a professional to take a look. Don’t neglect or put off repairing your deck, joists, railings, or stairs because they will get worse over time, making repairs more expensive and difficult to do.

Spring Cleaning

After winter, you’ve inspected your deck, and now it’s time to clean up for spring. Wash off any remaining ice melt and remove any snow or ice water. If you want, you can wash your deck again. Once your outdoor deck is dry, you can put back all your furniture, planters, trellises, lighting, and decorations.

Other Considerations for Protecting Your Deck in Winter

In addition to the above protection work that needs to be done, there are some different measures to take to protect your outdoor deck, depending on your living environment.

Remove Dangerous Tree Branches

If you have trees near your yard, check the branches before winter and cut off any branches that look weak. Weak branches can break in cold weather or when snow accumulates. If the tree is near your porch, a broken branch can cause significant damage to your deck.

In addition to checking branches, you need to check the trunk of the tree and the roots and other locations for signs of decay. If you think these trees are dying or are at risk of falling, call a professional to have the tree removed.

If you find that one of these is draining onto your deck, try to move it or change its direction before winter arrives. Once you’ve fixed the problem, you can use a towel, mop, or squeegee to gently push any standing water off your deck.

Keep an Eye Out for Icicles and Ice Dams

Icicles may look beautiful, but they can be a danger to you, your house, and your deck. When an icicle breaks and falls, if it’s sharp or heavy enough, it can hurt anything it touches. Icicles can also become ice dams, which can be very dangerous.

Ice dams can form on your roof or in your gutters when icicles and snow melt and then freeze into large clumps, or “dams”. These ice dams prevent water from draining properly from your roof, which can lead to costly and extensive damage. When the ice dams melt or break, the extra water and weight can hurt your deck.
