You are asking where to caulk the vinyl siding?

You'll only use a tube or two of caulk on a proper vinyl siding job. The real waterproofing is mechanical flashing, not caulk. Vinyl siding needs to move; caulk doesn't like movement.

@Mark Bischak, Architect and @Joseph Corlett, LLC yes, such as where the electric comes into the house, or where siding meets brick. I just don't want to call anyone back to the job after they've moved on. Which other areas?

Thanks!
