Full Tear-Off of the Old Siding
Every panel comes off, down to the sheathing. Going over the top of old siding hides exactly the things you are paying us to find — soft sheathing, failed wrap, water tracking behind a window — and it adds a layer that traps whatever moisture is already in the wall.
It is more work and it is the only way to know what you actually have. The wall gets opened, looked at, and photographed before anything new goes on it.
