I have some timber siding (planks of wood) that over lap. I've been told its shiplap but according to the place I got my wood the wood is shiplap but the style of overlaying it is something else.
Anyway, you know what I have, my question is how do I remove a rotten piece that when the house was built had a exterior porch added on later so now most of the wood is inside the house and some of its out side.
I assume that you lift the planks above to remove it but how do I cut out the bad part with out causing further damage?
