Paul,
So many variables it's hard to say for sure. How many workers, what size reveal, how many windows and doors to cut around, what kind of trim and how much.
It installs the same as regular clap board. The cut ends need to be treated and butt joints caulked with their caulk.
It's good to have a set of power shears.
It's good stuff, but make sure your up wind when cutting.
OK Thanks.
