Three Common Deck Mistakes

Building a deck on your own can be rewarding, but there are common mistakes that can lead to big problems down the line. Here are the top three mistakes to avoid if you're planning a DIY deck project.

1. Skipping Proper Foundation Work

One of the biggest errors people make is not putting enough attention into the deck’s foundation. The foundation holds the deck up and keeps it stable, so it's crucial to do it right.

• Wrong Footings: You can't just stick posts into the ground or use concrete blocks. The footings need to be deep enough and set in concrete to prevent shifting or sinking over time.

• Ignoring Drainage: Not accounting for water drainage around the foundation can lead to pooling, which can weaken the support over time.

  
  

2. Improper Framing

The framing is the backbone of your deck, and mistakes here can lead to structural issues later.

• Joist Spacing: Many DIYers place joists too far apart to save money. This can cause the decking boards to sag or feel bouncy over time. Stick to the standard 16-inch spacing to avoid problems.

• Ledger Board Problems: If the ledger board, which connects the deck to your house, isn’t installed correctly, the whole deck can pull away from the house. Use the right fasteners and flashing to keep it secure and protect it from water damage.

  
  

3. Poor Decking Installation

Even if the foundation and framing are solid, bad decking installation can make the whole thing look unprofessional.

• Not Leaving Gaps: Wood expands and contracts with the weather. If you don’t leave a small gap between the boards, they could buckle or warp as the weather changes.

• Wrong Fasteners: Using nails instead of screws is a common mistake. Nails can pop out over time, while screws provide a longer-lasting, more secure hold.

  
  

Conclusion

If you're tackling a deck project, make sure to pay attention to the foundation, framing, and decking installation. Avoiding these common mistakes will help ensure your deck is safe, stable, and lasts for years to come.
