Even the most well-kept wood siding is susceptible to moisture and damage which will lead to rotted wood. If you find a small portion of rotting wood, you can prevent it from affecting the entire wood siding. You simply have to remove the damage section and fill in that particular area. Below are the materials that you need along with the instructions on how to repair rotted wood siding.



Step 1-Examine Wood Piece for Actual Damages

Examine the piece of wood carefully in order to determine how much damage there actually is. Mark the ends of the damaged section about half an inch into the section of the wood that isn’t affected by damage, running through the wood piece’s full length.


Step 2-Cut the Damaged Portion Of Wood

Before cutting the rotting portion of the wood, make sure to wear protective glasses to avoid eye injury from flying splinters. Using the markings as guides, cut the wood piece using a circular saw with a blade depth that is a little smaller than the actual width of the wood. Using a claw hammer, remove all the nails that connect the wood to the structure itself. Using the hammer and chisel, you can finish off the cutting process of the wood and detach it from the structure it was attached to. Discard of that piece of damaged wood.


Step 3-Paint the Exposed Edges

Use paint to cover up the exposed edge. Be sure to use the same color that was applied onto the painted panel. The paint will protect the exposed edge from damage caused by exterior factors. Wait for about two hours for the paint to completely dry before proceeding to the next step.


Step 4-Cut New Wood Piece

Measure the exposed space, and cut a new wood plank that is exactly the size of the wood piece that was just removed. You can use the circular saw to cut this. Apply the same paint color on the edges of the new wood piece, and wait another two hours for the paint to dry.


Step 5-Secure New Wood Piece on the Space Provided

Place the new wood piece under the lower edge of the blank in the upper plank. Position the groove along the bottom part of the new wood piece, onto the upper edge of the wood piece. Using 2 ½-inch siding nails, attach the new wood piece. The nails should be placed into each of the individual wall studs. In the event that the edges of the new wood piece overshoot a wall stud, use 1 ¾-inch nail to secure it directly onto the structure of your house. The wood siding must be at least 5/8 inches in thickness.


Step 6-Paint the Replacement Wood Piece

Use the same paint color of the existing wood planks to coat the new wood piece. This will help protect the new wood plank from damage coming from weather elements, such as rain and intense heat during summer.
