Winter brings snow, sleet, ice and temperature extremes. While you may burrow inside for protection, your deck is left outside to brave the elements which wreak havoc on its bare wood planks. However, with a bit of forethought, planning and help, you can ensure that beautiful gathering spot will be awaiting you with the spring thaw.

Removing all mobile items from the deck floor helps prevent markings from becoming permanent.

Make sure to keep your deck free of dirt and debris. Autumn leaves, pine needles and other clutter traps moisture which encourages mold, mildew, discoloration and rot. Furthermore, this debris and grime become slippery when wet. Routinely sweeping these fall staples off your deck protects its surface and your guests.

Snow Removal

Some years bring drifting snow even as the leaves fall. For the protection of your deck, removing the snow in the fall and the coming winter months proves valuable. In the spring, your efforts will be rewarded with less damage and fading.

Remove With Care

When removing snow and ice, a snow blower is preferred. However, a shovel works in its absence, if used with care. Just be certain to move the shovel along the planks rather than across them to avoid scraping or chipping the wood.

A professional job offers water repellent sealing to stave off these effects. This investment proves wise for the future life of your deck.

Testing for Water Repellency

If the water beads in some areas, these spots do not necessarily need sealing. However, some professionals would recommend protecting your deck yearly for best results. If you are uncertain as to the level of your deck’s current protection, a professional can help make this determination.
