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.

The problems with composite decking include a high rate of expansion and contraction from temperature swings. This characteristic can cause boards to split, delaminate, or peel. In addition, significant movement can cause shrinking, warping, twisting, and bending. For this reason, you should minimize moisture and ensure proper airflow below your deck.

To prepare a deck for a hot tub, start by thinking about safe and easy access in and out of the tub. Homeowners should plan for steps or consider built-in seating, a level surface around the perimeter, and a clear, slip-resistant path from the house. A hot tub requires sufficient space around it for comfortable entry and exit, ensuring no awkward squeezing or stepping over high edges. Good lighting and handrails can also make a big difference, especially for nighttime use.

You typically don’t need a railing and handrails on a deck that’s less than 30 inches from the ground. However, consider adding them regardless. Railings provide additional safety for you and your guests who use your deck—plus, railings give the deck a more finished look than it would have without them.
