The “best” material is in the eye of the beholder, as each common decking material boasts its pros and cons. Poured concrete is the best budget-friendly option, but composite wood brings high-grade aesthetics without breaking the bank. Wood is the most traditional material, but it requires more maintenance than some other materials. In other words, do your research before settling on a deck material to find the one that’s best for your pool.

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.

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.

Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.
