Many homeowners eyeing a deck rebuild often wonder whether they can save on costs and effort by repurposing the existing deck posts. While the straightforward answer might be “yes,” there are several critical factors to consider before you decide. Let’s walk through these considerations to help you make the best decision for your project.
Is Rebuilding Your Deck on Existing Posts Possible?
The short answer is yes, you can rebuild your deck on the existing posts, but this depends on several factors. Before jumping into the project, it’s essential to assess whether your current posts are up to code and capable of supporting the new structure. If you’re simply replacing the deck surface without changing the size, there’s a higher chance that your posts may still be usable. However, if you’re expanding the size or adding additional features, you may need to modify or add posts to meet safety standards.
Considerations for Deck Expansion
If your goal is to rebuild your deck but also expand its size, the situation becomes more complex. When increasing the size of your deck, it’s almost guaranteed that the current posts will need to be moved or more posts will need to be added. This ensures that the deck can support the increased weight and size safely. A larger deck places more load on the structure, and without the right number of posts in the correct positions, your new deck may not be able to handle that load. As we always emphasize with our projects, ensuring safety and durability is a top priority.
Issues with Current Installation Methods
A common issue we encounter during deck rebuilds is how the posts were originally installed. In some new construction homes, the posts are buried directly in the ground. While this method may be more cost-effective in the short term, it is a recipe for long-term failure. Even treated lumber, when buried directly in the soil, is not designed to withstand constant ground contact for an extended period.
Over time, moisture in the soil can cause the wood to deteriorate. If your yard has poor drainage, water may accumulate around the posts, accelerating the decay process. Within 10 to 20 years, these posts can weaken to the point where the deck becomes unsafe. This is especially concerning for two-story decks, where the risk of structural failure can lead to serious safety hazards.
Importance of Proper Deck Post Installation
One of the most important factors in determining whether you can rebuild your deck on existing posts is how those posts were originally installed. Proper deck post installation involves setting the posts above ground on a sturdy concrete footing, which prevents them from being exposed to direct moisture in the soil. If your posts were buried or are made of a material not suited for ground contact—such as cedar—it’s best not to reuse them.
Cedar, while naturally resistant to rot, is not suitable for direct ground contact. If your existing cedar posts are buried in the soil, they likely need to be replaced with posts that can withstand those conditions or properly installed on footings to extend their lifespan.
Assessing the Condition of Your Deck Posts
Before deciding to rebuild your deck on the current posts, you should assess the material, installation method, and the overall condition of the posts. Here are some key points to check:
- Material: Are the posts treated lumber or cedar? Cedar posts buried in the ground should not be reused. Treated lumber has a better chance but needs to be inspected carefully.
- Installation: Were the posts installed on a concrete footing, or are they buried in the ground? If buried, the posts will likely have experienced some decay.
- Condition: Check for signs of rot or damage. Posts that have started to rot or weaken over time are unsafe and must be replaced.
In Summary
Ultimately, deciding whether to rebuild your deck on existing posts depends on several factors, including the condition of the posts, the materials used, and whether they were installed properly. While we always strive to save our customers money, we never cut corners when it comes to safety. If the existing posts meet current building codes and are in good condition, we can certainly explore the option of reusing them. However, if the posts are buried, made from improper materials, or compromised by rot, replacing them will be the safer option.
