In this episode of Deck Builders St Louis, we outline simple seasonal maintenance steps that help your deck last longer through St Louis winters and summers. Many homeowners are unsure what they should actually do beyond sweeping and an occasional wash. We break maintenance into clear, manageable tasks you can tackle once or twice a year, whether your deck is wood, composite, or a mix of surfaces tied into patios and pergolas.

We explain what to look for in spring inspections, including loose fasteners, soft spots, and railing or stair movement, and how early fixes prevent larger structural issues. Then we talk about cleaning methods for wood and composite decking, how to manage mildew and debris, and when sealing or staining makes sense for wood boards. We also touch on how to check around ledgers, posts, and under-deck areas for trapped moisture and blocked drainage.

Material type guides some of these steps. Composite products from manufacturers like Fiberon need different care than traditional lumber, with more focus on gentle cleaning and less on coatings. We explain how to adjust your routine based on the materials used on your deck, and how to keep surfaces safe and slip-resistant around outdoor kitchens, furniture, and high-traffic zones. With a simple plan, you can keep your deck ready for use in every season.
