The arrival of Jack Frost can create problems for an unprotected wooden deck. Snow, sleet, and ice cause moisture and structural issues such as wood rot and mold growth. Here are a few steps for fortifying the highly customized lumber for winter weather, so it’s ready for use in the spring.

5 Ways to Prepare a Wooden Deck for the Winter

1. Remove All Furniture & Planters

Place outdoor furniture in your garage, basement, or storage unit. Move planters that will remain outside through the winter onto a nongrassy area of your property, instead of leaving them on your deck. Furniture can stain the lumber with rust or mildew, while drain holes at the bottom of planters allow moisture to accumulate and freeze, resulting in rot.

2. Clean

Sweep the entire deck to remove leaves, twigs, dust, and other debris. Eliminate mold, mildew, algae, and ground-in dirt from your deck with a pressure-washer and nonbleach cleanser. Your local deck supply company will provide cleaning product suggestions if you need extra assistance. Allow the deck to dry thoroughly before repainting or applying sealants.

3. Inspect It for Weak Spots & Other Problems

Check the lumber for rotted spots, cracks, and other signs of serious wear and schedule replacements as necessary. Focus on the joists which are susceptible to mold and rot because they do not get exposed to the sun. Also, check the screws and nails, as some may be loose or sticking up and need to be replaced.

4. Trim Overhead Trees

Request tree trimming services to keep branches from hanging over your deck this winter. Overhanging branches contribute to debris accumulation and can form icicles that drip onto the lumber, resulting in dangerous icy patches and wood rot. Tree trimming also keeps vulnerable branches from hitting your deck and home during winter storms.

5. Apply a Protective Finish

Create a barrier between the elements and your deck with a quality protective finish. Sand and paint the lumber first if the current paint is chipping, and allow the deck to dry before using a recommended wood sealant that prevents cracking, splintering, and warping, as well as rot. Do not use rock salt to melt ice since it can cause the finish to deteriorate; use a sturdy plastic shovel or snow blower instead.
