We just discovered what appears to be rot on an aluminum-clad Pella Pro-Line window in the family room. The window is a bank of 5 windows, and the one with the problem is next to the end on the left. Windows were installed when the house was built in the second half of 1993.
For lack of a graphics tool, assume the windows are as done below.

What appears to have happened is that the aluminum cladding at the bottom has failed, as the outside right bottom corner of cladding is lose. So water (rain, sprinkler, etc.) has gotten inside to the wood and it appears that we have rot.
I am arranging for Pella to come look at the problem and give their recommendation. However, my question is this: in your opinion, will it be necessary to replace the entire set of 5 windows, or will it be possible to replace just the wood that has rotted?
The exterior is a synthetic stucco (competitor to Dry-Vit) and it will be a problem matching the rest of the house if the stucco must be redone.
Thanks for your advice.
