Tips for Winterizing your Redwood Deck
While redwood is naturally weather resistant and makes it a great candidate for outdoor structures it can still be susceptible to freeze-thaw cycles especially in East Idaho's harsher winters. Water can seep into the wood, freeze and cause it to crack or warp if the surface is not properly prepared. Snow and ice can trap moisture against the wood leading to rot and mildew, if not properly cared for. Winter proofing your deck helps preserve the beautiful redwood color and texture, preventing the greyish tone that results from weathering. Here are a few important things to consider when preparing for the winter months.
The first step is to inspect your redwood deck for signs of wear and tear in the Fall. Thoroughly inspect your deck, checking for loose boards, protruding nails or screws, or signs of rot. Repairing the damage now prevents any issues from getting worse over the winter months. For loose boards, simply tighten screws or hammer nails back in.
Look for discolouration, soft spots, and wood that easily crumbles. Closely inspect areas regularly exposed to water, like near downspouts or under planter boxes, soft spots or splintering can be signs of rot. Avoid opportunities for standing water by ensuring your deck has proper drainage. If you have planters on the deck, use saucers to prevent water from sitting on the deck boards. Rotten boards need to be replaced immediately to prevent spread and dangerous deck conditions.
Next, clean your deck thoroughly. Use a broom or leaf blower to remove leaves, dirt, and debris from the surface. Built up debris is what traps water on your deck and leads to rapid rot and decay. Giving your deck a thorough wash with mild soap and water or a cleaning solution specific to redwood decking. *Be sure to carefully follow the manufacturer's instructions* If you spot mold or mildew, address it quickly. Use a mildew-resistant cleaner and a soft-bristle brush to remove any existing issues.
Consider applying a high quality deck stain or sealer to preserve the natural look of your deck and protect it from the elements. Prepare the deck by sanding the surface prior to applying any stain or sealer. A sealed deck is less prone to moisture penetration, UV damage, and surface graying. You will know if your deck needs a stain or sealer, if water is no longer beading up and sitting on the surface. Be sure to choose a product specific to redwood decking and carefully follow the manufacturer's instructions.
You may consider installing a roof cover for an extra level of protection. A roof cover will keep the majority of snow off your deck during the winter months and add much needed shade in the summer. Be sure to store deck furniture or get waterproof covers to protect your outdoor furniture from the elements. Before covering, clean the furniture and remove any dirt or debris that may lead to stains.
Winter maintenance is key, regularly brush off leaves, twigs, and other debris that may be holding moisture against the surface. Use a plastic shovel to clear snow, removing the snow parallel to the boards to prevent catching a seam and chipping or damaging the wood. Throughout the winter keep an eye on your deck for signs of water damage, and try to address the immediately, to prevent further damage. Avoid using salt or chemical deicers as they damage the wood and corrode metal fasteners. Opt for pet-safe and wood-safe deicing products or sand for traction.
The maintenance of redwood decks can feel overwhelming but with proper winterizing you can keep your deck protected during the winter months. This prep work will make your spring cleaning a breeze and extend the life of your deck. With proper care and maintenance, your deck will continue to look like new. Now is the time to get started on your Fall maintenance!
