What to Surround Your Deck's Bottom With

When it comes to building a deck, one of the most crucial aspects often overlooked is what to put around the bottom of your deck. This area, known as the ledger board or rim joist, plays a significant role in the deck's stability, durability, and appearance. Let's explore the best practices and options for this critical component.

Properly addressing the bottom of your deck isn't just about aesthetics; it's about preventing water damage, pest infestation, and even structural issues. It's also an opportunity to enhance your deck's overall look and feel. So, let's dive into the details and discover what you should consider when choosing what to put around the bottom of your deck.

Understanding the Ledger Board

The ledger board is the horizontal board at the bottom of your deck, attached to your home. It's the foundation that supports your entire deck structure. Understanding its role is crucial in deciding what to put around it.

Before we delve into the options, it's essential to note that the ledger board should be securely attached to your home's band joist using appropriate hardware and following local building codes. This ensures your deck is safe and stable.

Pressure-Treated Lumber

Pressure-treated lumber is a popular choice for ledger boards due to its resistance to rot, decay, and insect damage. It's designed to withstand the elements, making it an excellent option for the bottom of your deck.

However, while pressure-treated lumber is durable, it's not immune to damage. It's crucial to protect it from direct contact with the ground using a ledger board skirt or other protective measures. This helps prevent moisture buildup and extends the life of your ledger board.

Composite Materials

Composite materials, such as those made from recycled plastic and wood fibers, are another option for ledger boards. They're resistant to rot, decay, and insect damage, much like pressure-treated lumber. Plus, they require minimal maintenance.

Composite ledger boards can be a good choice, especially if you're building a composite deck. They provide a consistent look and feel throughout your deck structure. However, they can be more expensive than pressure-treated lumber.

Protecting the Ledger Board

Regardless of the material you choose for your ledger board, protecting it is crucial. This involves more than just what you put around the bottom of your deck; it's about how you build and maintain your deck.

Here are some ways to protect your ledger board:

Ledger Board Skirts

Ledger board skirts are flashing materials that wrap around the bottom of your ledger board, creating a barrier between it and the ground. They help prevent moisture buildup and direct water away from your ledger board.

Ledger board skirts can be made from various materials, including metal, plastic, and composite. Each has its pros and cons, so choose one that fits your budget and your deck's design.

Ventilation

Proper ventilation is another key to protecting your ledger board. This involves leaving space between the ground and your ledger board to allow air to circulate and prevent moisture buildup.

You can achieve this by using ledger board spacers or building your deck on stilts. The goal is to keep your ledger board dry and well-ventilated, which helps prevent rot and decay.

Regular Inspections

Regular inspections are crucial for maintaining your deck's safety and longevity. This includes checking your ledger board for signs of damage, such as warping, cracking, or rotting.

If you notice any issues, address them promptly. This could involve replacing a damaged section of your ledger board or reinforcing it with additional support.

In the end, what you put around the bottom of your deck is about more than just aesthetics; it's about creating a safe, durable, and long-lasting structure. By understanding the role of the ledger board and choosing the right materials and protective measures, you can build a deck that's not only beautiful but also built to last.
