A starter strip is the foundation of any vinyl siding job, so run it level along the entire base before hanging the first course. Keep the recommended 1/8 in. clearance at corner posts and J-channel and 1/4 in. between strip ends to allow for thermal expansion. Mill-finish aluminum is a practical, economical choice where the strip will be hidden behind the first siding course.

Cut aluminum edges can be sharp; wear gloves and eye protection when handling and cutting starter strip.
