The house we recently bought has aluminum Siding. We installed new windows but changed the size. Can we patch in the gaps with pieces of old siding? I don't want to reside the whole house. We plan to repaint the siding when work is complete and I believe that could hide the odd seams around the windows. The contractor thinks it will be time consuming to the point where he could have new vinyl up. I don't particularly like the idea of vinyl when we have nice aluminum through the other 90% of the house.
