How to Deck/Patio Sealing

Your deck endures constant exposure to sun, rain, snow, and foot traffic, causing the protective sealant to break down over time. This comprehensive maintenance task involves deep cleaning the wood surface to remove dirt, mildew, and gray weathering, then applying a fresh coat of sealant or stain to restore UV protection and water resistance. Regular sealing preserves the wood fibers, prevents cracking and splintering, maintains the deck's appearance, and dramatically extends its lifespan—potentially saving you the $15,000-$30,000 cost of premature deck replacement.
