Yes, pressure washing a wood deck can be a good idea as it effectively lifts ingrained dirt, mold, and mildew, improving the deck's appearance and longevity. However, it must be done carefully, as it's easy to damage the wood, especially softwoods. To pressure wash safely, use a lower pressure setting and a wide, 40-degree fan pattern nozzle (often white). Keep the nozzle at least a foot away from the wood surface and maintain constant motion, avoiding hovering in one spot to prevent gouging.

Deck skirting shouldn’t touch the ground, especially if you have a wood deck, which is vulnerable to moisture. Ideally, you should leave at least 3/4 of an inch of space between the deck skirting and the ground for more ventilation. Pros also recommend that you incorporate about 1 square foot of space for ventilation for the underside of the deck to every 150 square feet of decking. Proper ventilation prevents mold growth and rot that can damage your deck.

Before installing any materials under the deck for removing moisture, you should perform some prep work on the ground. Work the dirt under the deck to create a grade away from the home. A grade of at least six inches for every 10 feet works well. Do not leave a gap between the dirt and the home’s foundation where water could pool. Once you or a contractor regrades the dirt under the deck, you then can add materials over the top.

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.
