If you are installing a new deck, you need to carefully figure out the material you want to use for the deck. The material you choose for the deck will impact the cost of the deck, the maintenance the deck requires, and the lifespan of the deck.

Material Choice #1: Pressure-Treated Lumber

When it comes to the most affordable option for the material for your deck, pressure-treated lumber is often one of the top choices. Pressure-treated lumber is easy to cut and work with. It is also pre-treated with chemicals that will help keep away fungus, rot, and insects that like to eat wood.

The downside to pressure-treated lumber is that it is more likely to crap and warp than other types of decking material. Although pressure-treated lumber is cheaper upfront, in the long run, you will have to invest in regular maintenance. You will need to power wash your deck every year, and you will need to apply a new wood preservation stain to the deck every couple of years.

Material Choice #2: Composite Boards

Composite boards, often referred to as plastic lumber, are another very popular decking material. Composite lumber is made from a combination of wood fibers and recycled plastic. The materials are combined to create what looks like ordinary lumber boards. However, composite boards are specially designed so that they will not warp, split, rot, or splinter over time. They are weather and stain-resistant as well.

Composite decking is also popular because they are relatively easy to take care of. You will not need to stain or sand the deck down over time. You do need to keep your deck clean with regular sweepings and yearly pressure-washing, as mold and mildew can grow on a composite deck.

Material Choice #3: Aluminum Decking

A less popular and more expensive choice is aluminum decking. There are a variety of companies that create aluminum boards you can use to create your own custom patio. The boards are made with interlocking edges, which allow you to create a watertight deck. Self-draining channels are built into the boards to remove water from the deck.

Aluminum is a great decking material. It will not rot, warp, splinter, or crack like a wood deck. Bugs that like wood are not going to be interested in your aluminum deck. Aluminum also doesn't rust, so you don't have to worry about having a rusty metal deck. Additionally, an aluminum deck will not catch fire.

When it comes to choosing the materials for your deck, you have a lot of different options. Pressure-treated wood is really affordable but requires a high degree of long-term maintenance. Composite boards are sturdy and need regular cleaning. Aluminum decking is expensive, but not prone to damage. There are other decking materials you can explore for your deck, such as tropical hardwoods, redwood, and cedar. Talk to your deck installation contractor to determine the best decking material for your home, budget, and style needs.
