How to Maintain Your Decking During Autumn and Winter

After you enjoyed your deck during summer, entertaining friends, outdoor dining, and cooking on the BBQ, your deck will need some maintenance to prepare it for season changes. Your deck should be protected during autumn and winter to prevent moulds, mildews, and water damage.

Having a well-maintained deck during winter and autumn will increase longevity and make it stronger. Aside from that, your deck will be prepared for spring and summer where you’ll spend most of your time outdoors. Here are a few steps on how to maintain your deck during autumn and winter:

Clean the Surface of the Deck

During autumn and winter, the surface of your deck will build up dirt, grime, and leaves. If left on your deck, it can damage your deck and create a mulch. This will cause rot and decay. That’s why during these times, deck maintenance is crucial.

Sweeping and washing the surface of your deck will prevent the growth of moulds, algae, mildew, and moss during winter. It is recommended to use a power washer to remove dirt and debris quickly and easily. Leaving your deck’s surface squeaky clean!

Remove Seating or Planting

If you have planters or seating in your deck, it’s best to put them in storage. Leaving them on your deck during autumn and winter will create damp spots in your deck. This will increase the moisture build-up in that particular area, which will cause decay or rot.

Apply Water Repellent

A water repellent is applied to your decking within three days or one week after applying a timber treatment. This will increase the longevity of your decking and will keep it protected from moisture. Not applying the water repellent will let water penetrate the cracks or gaps of the wood and cause it to rot.

Check Signs of Rot and Decay

Hardwood deckings age over time. Inspecting your deck regularly will help you save time and money. It’s best to look for signs of damage before winter where your deck will be exposed to moisture. It will also make your deck stronger to prevent any further damage.

Fall is the best time to check for cracked wood, loose planks, raised nails, shaky railings, termite damage, and warped wood.

Don’t Let Snow Pile Up

During winter, your deck should be kept clean and dry all the time. Melting snow can ruin any type of wood and can increase the build-up of moulds and mildew.


To ensure that your deck will last longer, you should know how to properly take care of and maintain it. This is also in preparation for summer where your deck will be used more often. if you notice any signs of damage or aging, it’s best to consult a professional.
