New Construction Windows vs Replacement Windows: Which Should You Choose?

This decision usually shows up when the job moves from estimates to actual framing, trim, and glass selection.

The difference matters more than the label suggests.

That basic distinction drives almost everything else, from cost to appearance to how much of the original window opening stays in place.
