To get at the nails in the board above, shove a flat pry bar up under it and gently pry the board outward. In most cases, this will pop up the nailhead, so you can pull it with your hammer claw. If you run into a stubborn nail that won’t move easily, don’t use brute force and risk splitting the good board. Instead, slip a hacksaw blade behind the siding and cut the nail (Photo 2).You can’t get the new board in unless you pull the remaining shank of the cut nail (Photo 3).
EPA's Lead Renovation, Repair and Painting Rule (RRP Rule) requires that firms performing renovation, repair, and painting projects that disturb lead-based paint in homes, child care facilities and pre-schools built before 1978 have their firm certified by EPA (or an EPA authorized state), use certified renovators who are trained by EPA-approved training providers and follow lead-safe work practices. http://www.youtube.com/watch?v=b6_WEt9k_Hw&feature=youtube_gdata
