How to Remove Clapboard Siding

  • Removing siding and drilling through sub-siding for access to wall cavities eliminates the need to spackle, prime and paint over plugged holes.

 

Step 1

Use a utility knife to cut through the paint at the end joints. If only a portion of the board needs to be removed, cut a new vertical joint with a back saw.

 

Step 2
Remove Upper Nails

Remove Upper Nails

Insert the siding chisel at a nail location between Clapboard 1 and Clapboard 2.  This may loosen the nail enough to allow a clean grab and pull with the claw hammer. If not, cut the nail by driving the chisel.  Remove or cut all nails holding the top of Clapboard 2.

 

Step 3
Remove Lower Nails

Remove Lower Nails

Insert the siding chisel at a nail location under the lower edge of Clapboard 2.  These nails also go through the upper edge of Clapboard 3.  Use the same method described in Step 2 to remove or cut the nails.

 

Step 4

The board should be loose enough so that when it is pulled straight down it comes free.  Be careful not to pry or pull the board out or up as this action may cause Clapboard 1 to break.

 

Step 5
Cut Building Paper

Cut Building Paper

Building paper is usually found between the clapboards and the sub-siding. To prevent damage to the building paper, use the utility knife to cut a flap slightly larger than the size of the the hole to be drilled.  Make the first cut horizontally just above the clapboard still in place.  Then make vertical cuts on each side.  Fold the paper back to reveal the sub-siding.  After drilling and filling the cavity, drive a wood plug flush with the sub-siding.  Then fold the building paper back into place.

 

Step 6
Replace Board

Work the clapboard back into its proper position.  Use new finish nails of the same size.  Fill any unused nail holes or splits in the board with exterior spackle.
