Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

Putting lattice under a deck will create a polished look that allows for air ventilation. You can also store items underneath as the lattice provides privacy and protection from the weather. You can also put lattice under a porch to create a polished look in the front of your house.

Cutting the boards directly is one of the fastest ways to remove deck boards with hidden fasteners. Mark two parallel lines that are one-third of the total measurement on both ends and cut out the centerpiece. Then, remove the end of the board that doesn’t have a fastener. Finally, pry open the fastened side and pull it up to pop out the screw or access the fastener. This also allows you to salvage portions of boards for other projects.

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.
