How to repair shiplap siding

Shiplap siding is a popular building material that provides protection to your home's underlying structure against water damage and sunlight. Over time, however, it may become necessary to repair damaged shiplap siding to maintain its functionality and aesthetic appeal. In this blog post, we will guide you through the process of repairing shiplap siding, ensuring a seamless and effective restoration. Let's get started!

Tools You'll Need:

  • Circular saw
  • Pry bar
  • Slater's ripper
  • Hacksaw blade saw
  • Mallet
  • Corrosion-resistant nails

Step 1: Assess the Damage Identify the damaged section of the shiplap siding that requires repair. It's important to determine the extent of the damage to ensure accurate repair and replacement.

Step 2: Prepare for Removal Using a circular saw, carefully cut the damaged siding board in half lengthwise. Adjust the saw blade depth to match the thickness of the siding board. This will allow for easy removal without affecting the surrounding boards.

Step 3: Remove the Damaged Board Insert a pry bar near the nail holes on the bisected board and gently lift the split halves until the shafts of the nails are visible. Next, employ a slater's ripper to pull the nails up or use a hacksaw blade saw to cut the nail shafts. Remove the two pieces of the damaged siding board from the wall.

Step 4: Cut and Install the Replacement Board Using the circular saw, cut a new piece of shiplap siding to the proper length, ensuring it matches the existing dimensions. Notch the top edge of the board underneath the overhanging bottom edge of the board above for a secure fit. Carefully slide the replacement board into place and use a mallet to gently knock it into position.

Step 5: Secure the Replacement Board Fasten the replacement board in place using corrosion-resistant nails. For a consistent appearance, follow the existing nail patterns when inserting the new nails. Ensure the board is securely attached to the underlying structure.

Step 6: Finishing Touches Inspect the repaired section for any protruding nail heads. If necessary, use a hammer and nail set to recess the nail heads slightly below the surface. This will allow for a smooth and uniform appearance.

Repairing shiplap siding is a straightforward process that involves cutting out the damaged section and replacing it with a new board. By following the step-by-step guide outlined above, you can effectively restore the integrity and beauty of your shiplap siding.

Regular maintenance and prompt repairs will ensure the longevity and protection of your home's exterior and your timber shiplap cladding. Remember to prioritise safety and accuracy throughout the repair process, and your shiplap siding will continue to safeguard your home for years to come.
