Pressure-treated lumber is one of the most affordable types of decking upfront. This material is widely available, so you can usually find pressure-treated lumber at almost any local home improvement store you visit. Keep in mind that wood requires a lot of upkeep with repainting and restaining, so any kind of wood may be more expensive in the long run than something like PVC decking.

Yes, Ipe wood is a popular high-end choice for pool decking. It repels water and is naturally slip-resistant. It's not susceptible to mold, mildew, or rot, either, so it lasts longer and is cleaner and more hygienic than other popular decking materials. However, remember that due to its status, it is a very high-cost wood, and you might find that an alternative would serve you just as well for significantly less.

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.

Yes, adding railing to a deck is a great way to improve safety and your home’s aesthetic appeal. Railings can be constructed from wood, metal, or composite, and there are plenty of choices regarding design and style. Always consult local building codes before starting any building project—there are often requirements regarding spacing and height that can differ slightly from place to place.
