I need to repair some woodpecker damage on a cedar sided house I will working on soon. The woodpeckers are putting holes in the corner boards only, towards the soffit, nothing in the clapboards. I repaired the damage 4 years ago with wood filler and re-stained, only to have them come back and peck holes in the same areas again. The homeowner even filled the holes once last year only to have them put new holes in the same area again. This time I want to replace the corners with new material, but not sure if I want to use cedar again for fear of them putting holes in the new boards again. I think they are actually trying to find carpenter bees that drilled inside the wood, so Im wondering if I can use another material other than wood that wont allow the carpenter bees or the woodpeckers to destroy it again. My thoughts are leaning towards PVC(Azek) or possibly fiber cement based trim(Hardieboard). any thoughts on this odd problem?
