Yes, you can build a pool deck yourself, but it takes precision, a lot of time, and many specific tools. You’ll need to create a deck plan, be careful with measurements, cut each piece of wood, secure the pieces properly, and ensure the deck meets building codes. Building a deck around a pool is a rewarding DIY, but it’s time- and labor-intensive, so thoughtfully consider your abilities and the time you have before embarking on this DIY.

A random orbital sander is best for sanding a deck because it is easier to handle than other power sanders and is less likely to damage the wood. Most decks are made of types of softwood, so a gentler sanding process is essential to prevent permanent blemishes. For example, belt sanders can gouge softwoods.

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.

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.
