Shiplap cladding is a popular choice for both interior and exterior walls due to its rustic appearance and easy installation process.
However, over time, it can develop issues that need fixing. In this guide, we’ll walk you through the steps to repair and maintain shiplap cladding, ensuring your cladding continues to look its best.
Understanding Shiplap Cladding
Shiplap cladding consists of wooden boards with a rabbet (groove) cut into the edges, allowing them to overlap and fit together snugly. This design provides a weathertight seal, making shiplap ideal for external use, but it is also favoured for interior applications due to its aesthetic appeal.
Common Issues with Shiplap Cladding
Before diving into the repair process, it's important to identify common problems that can arise with shiplap cladding:
- Cracks and Splits: Wood can crack or split due to changes in temperature and humidity.
- Warping: Boards may warp over time, causing them to bow or twist.
- Loose Boards: Nails or screws can loosen, leading to boards that rattle or detach.
- Rot and Decay: Moisture can lead to wood rot, especially in exterior applications.
- Discolouration: Exposure to sunlight and weather can cause fading or staining.
Tools and Materials Needed
- Replacement shiplap boards (if necessary)
- Hammer or screwdriver
- Nails or screws
- Pry bar
- Wood filler

Step-by-Step Repair Process
-
Inspect the Damage
Begin by carefully inspecting the shiplap cladding to identify the extent of the damage. Determine whether the issue can be fixed with minor repairs or if full board replacement is necessary.
-
Remove Damaged Boards
If you need to replace a damaged board, use a pry bar to carefully remove it. Start by loosening the nails or screws and then gently lift the board away from the wall. Take care not to damage the surrounding boards.
-
Replace or Repair Boards
For minor cracks or splits, use wood filler to fill in the gaps. Allow the filler to dry completely before sanding it down to a smooth finish. If the board is too damaged, replace it with a new shiplap board. Cut the replacement board to the correct length and secure it in place with nails or screws.
-
Address Warping
To fix warping, remove the affected board and lay it flat. Use weights or clamps to gently straighten the board. If it doesn't return to its original shape, replace it with a new one.
-
Secure Loose Boards
Check for any loose boards and resecure them with nails or screws. Make sure to use rust-resistant fasteners for exterior cladding to prevent future issues.
-
Treat and Protect
For exterior cladding, apply a wood preservative to protect against rot and decay. After the preservative dries, apply a sealant to create a water-resistant barrier. For interior cladding, you can use paint or wood stain to refresh the appearance and protect the wood.
-
Regular Maintenance
To keep your shiplap cladding in good condition, perform regular maintenance. Clean the surface periodically to remove dirt and debris. Inspect the cladding for signs of damage or wear and address any issues promptly.
Fixing shiplap cladding is a straightforward process that can be accomplished with basic tools and materials. By following these steps, you can maintain the beauty and functionality of your shiplap cladding, ensuring it remains watertight and looks good for years to come.
Remember, regular maintenance is key to preventing major issues, so take the time to inspect and care for your cladding regularly.
