The main reasons to have your deck cleaned by regular washing are to prevent it from getting slick, which can make it unsafe to use, and to improve the aesthetic appeal of your deck. Over the course of winter, algae and black mold can build up on your deck, starting to break down the wood and making your deck look unappealing. After washing, sanding is an important next step in deck maintenance as it prepares the wood for staining. Sanding will smooth out any splintering and remove the old finish from the wood, allowing for an even application of the new stain. When you stain wood with an oil-based product, that product penetrates down into the wood fibers and helps to preserve them. Additionally, the stain will act as a sealant, waterproofing your deck. Together these things will maximize the number of years of your deck’s life. Over time, as your deck is exposed to moisture and the elements, wood fibers can start to rot. This can happen prematurely if you’re not regularly cleaning, sanding, and staining the wood. When wood rots, you will likely need to invest in deck repair. Signs that you need deck repair include decking boards that feel spongy or brittle to the touch, cracks in your decking boards, or if the wood feels unstable when you step or put pressure on it.
