Best Deck Bottom Cover Options: What to Use & Why

When it comes to protecting the bottom of your deck, you have several options to choose from. The right choice depends on your specific needs, budget, and the look you're aiming for. Let's explore some popular materials and methods to help you make an informed decision.

Before we dive into the options, it's essential to understand why covering the bottom of your deck is crucial. It not only adds a finished look but also protects the structure from moisture, pests, and weathering, extending your deck's lifespan.

Pressure-Treated Lumber

Pressure-treated lumber is a popular choice for decking due to its durability and resistance to rot, decay, and insects. It's an affordable option that can be stained or painted to match your deck's aesthetic.

However, it's important to note that pressure-treated lumber contains chemicals that can leach into the soil over time. If you're concerned about the environmental impact, you might want to consider other eco-friendly options.

Skirting vs. Framing

When using pressure-treated lumber, you can choose between skirting and framing the bottom of your deck.

Skirting involves attaching boards around the perimeter of your deck, creating a barrier that hides the underside. It's a simple and cost-effective solution. Framing, on the other hand, involves building a full enclosure, which provides more protection and can be used to store items underneath the deck.

Composite Materials

Composite materials, such as plastic and wood fiber blends, are another popular option. They're low-maintenance, durable, and resistant to rot, insects, and moisture. They also come in a variety of colors and styles to match your deck.

While composite materials are more expensive than pressure-treated lumber, they may be a better long-term investment due to their durability and low maintenance requirements.

Vinyl and PVC

Vinyl and PVC are excellent choices for a clean, low-maintenance look. They're resistant to moisture, rot, and insects, and they won't fade or warp like wood. They also come in a variety of colors and styles to match your deck.

Vinyl and PVC are typically used for skirting, as they can be more challenging to install for full framing. They're also more expensive than pressure-treated lumber but can be a good investment if you're looking for a low-maintenance solution.

Metal and Aluminum

Metal and aluminum are durable, low-maintenance options that can add a modern, industrial look to your deck. They're resistant to rot, insects, and moisture, and they won't warp or fade like wood.

Metal and aluminum are typically used for skirting, as they can be more challenging to install for full framing. They're also more expensive than other options, but they can be a good investment if you're looking for a durable, long-lasting solution.

Screening and Lattice

If you're looking to add privacy or keep pests out, screening and lattice can be excellent choices. They allow for airflow while providing the protection you need.

Screening and lattice are typically made from wood, vinyl, or metal and can be installed as skirting or framing. They're more affordable than some other options but may require more maintenance, depending on the material used.

In the end, the best material for covering the bottom of your deck depends on your specific needs, budget, and the look you're aiming for. Whether you choose pressure-treated lumber, composite materials, vinyl, metal, or screening, each option offers its own set of benefits and drawbacks. Take your time to consider your needs and choose the option that best suits your deck and your lifestyle. Happy building!
