3 Steps to Winterize Your Deck

Posted 19 October 2016 8:55 PM by Jase DeBoer

For some, winter is a time to stash the outdoor furniture and get ready to watch the snow pile up on the deck until the spring thaw (if that’s you, we have important information for you below). For some, it’s a time to enjoy the deck in other ways, with outdoor heaters, fire pits, grills that never get stored and holiday décor (if that’s you, we’ll have a lot of info for you in our next few blogs).

Either way, it’s important to prepare your deck for your winter activity.

How to Winterize Your Deck

Decks need to be winterized, no matter what your plans are for it over the winter. Whether you plan on using it, or you spend the colder months reminiscing about BBQs, gatherings and kids running around, your deck may need some TLC after the past summer. Here is the step-by-step guide to preparing your deck for the winter months, to keep it enjoyable or to make sure it’s ready for next summer’s activities.

Step 1: Inspect

Inspect the entire deck. Check for loose screws, damaged boards, loose handrails, etc. Make adjustments and improvements if necessary. You’ll want to remove potted plants that sit directly on your deck boards, so moisture isn’t trapped, causing mold and mildew.

Step 2: Clean

Sweep debris off your deck. Wash the deck with a bleach-free cleaner or mild soap and water. If you come across staining or stubborn areas, use a brush to scrub them clean. Rinse your deck with a hose.

Step 3: Protect

Make sure your deck is completely dry. Use a water repellent finish to protect your deck against water damage that could be caused throughout harsh winter months.


Be cautious when shoveling snow off the deck. You’ll want to shovel parallel to the deck boards to prevent scratching of the boards.
