How to Replace Deck Boards Like a Pro


Replacing deck boards can rejuvenate your deck without the need for a complete overhaul. It’s a cost-effective solution to address weathered, cracked, or rotting wood decking.

If you’re handy with tools and ready to take on a weekend project, you can tackle deck board replacement with confidence.

This guide will walk you through the steps to replace deck boards like a pro, ensuring your deck remains a safe, enjoyable space for outdoor living.

Assessing Your Deck’s Condition

Before you start prying up old boards, it’s crucial to inspect your deck’s overall condition. Look for signs of rot or damage to the supporting structure, including joists and beams. If the underlying structure is compromised, it may need repair before you replace the deck boards.

When to Replace vs. Repair

If your deck boards are showing extensive wear, rot, or insect damage, replacement is likely the best option. However, minor cracks or splinters may be repairable with wood filler or a sand and refinish job.

How to Replace Deck Boards Like a Pro

Tools and Materials Needed

Replacing deck boards is a straightforward DIY project, but you’ll need the right tools and materials for the job:

  • Pry bar or deck wrecker tool
  • Hammer or nail puller
  • Circular saw or handsaw
  • Drill or impact driver
  • Deck screws or hidden fasteners
  • Replacement deck boards
  • Safety glasses and gloves

Make sure to choose deck boards that match the existing wood decking in size and type. If you’re uncertain about the best match, take a sample of your old decking to a lumberyard for assistance.

Step-by-Step Deck Board Replacement

Removing Old Deck Boards

  1. Safety First: Wear safety glasses and gloves to protect yourself from splinters and nails.
  2. Loosen the Boards: Start by using a pry bar or a specialized deck wrecker tool to carefully remove the old boards. Work one board at a time to minimize damage to the underlying joists.
  3. Remove Nails or Screws: Use a hammer or nail puller to extract any remaining nails. If the boards are screwed down, back out the screws with a drill or impact driver.

Preparing the Joists

  1. Inspect Joists: With the old boards removed, inspect the joists for damage. Replace or reinforce any that are not structurally sound.
  2. Clean and Protect: Sweep off debris and consider applying a wood preservative to extend the life of the joists.

Installing New Deck Boards

  1. Measure and Cut: Measure the length needed for each new deck board and cut it to size with a circular saw or handsaw.
  2. Fitting the Boards: Place the new board on the joists, ensuring it fits snugly against the adjacent boards. Leave a small gap (about 1/8 inch) between boards to allow for expansion and drainage.
  3. Securing the Boards: Fasten the new deck boards with deck screws or hidden fasteners. Start from one end and work your way to the other, making sure each board is straight and properly aligned.

Finishing Touches

Once all the new boards are installed, it’s time to add the finishing touches that will protect your deck and enhance its appearance.

Sanding and Sealing

  1. Sanding: Lightly sand any rough edges or surfaces to create a smooth finish.
  2. Cleaning: Sweep the deck and clean it with a deck cleaner to remove any sawdust or residue.
  3. Sealing: Apply a high-quality deck sealer or stain to protect the wood from the elements and help prevent future damage.

Tips for a Professional Finish

  • Stagger the Seams: If you’re replacing multiple boards, stagger the seams for a more professional look and added structural integrity.
  • Match the Finish: If you’re only replacing a few boards, try to match the finish of the new boards to the existing ones for a consistent appearance.

Maintenance Tips for Long-Lasting Decking

Maintenance Tips for Long-Lasting Decking

Proper maintenance is key to extending the life of your deck. Regularly clean and inspect your deck for signs of wear or damage. Reapply sealer or stain as needed, usually every two to three years, depending on your climate and the condition of your deck.

Common Mistakes to Avoid

When replacing deck boards, avoid common pitfalls that can compromise the quality of your work:

  • Ignoring Joist Condition: Don’t just replace the deck boards without checking the joists. Weak or rotting joists can lead to deck failure.
  • Improper Gapping: Leaving too little or too much space between boards can cause issues with drainage or warping.
  • Mismatched Materials: Using different types of wood or fasteners can result in an uneven look and may affect the deck’s durability.
