A straightforward panel swap on a door that's still in production - matching section ordered, bolted in, hardware adjusted - is a half-day job once the part is in hand. The complication in Zeeland is almost never the labor; it's the wait for the right panel to show up, especially on doors old enough that the manufacturer has moved on to newer rib profiles.
We'll tell you on the first visit whether what you've got is a part we can source in a normal order cycle or a door where full replacement is the faster and cheaper path. Pretending every older panel is a quick fix just delays the real answer by a few weeks and a few phone calls.
