The Difference Between Replacement Windows and New Construction Windows

Replacement windows and new construction windows may look similar from the street, yet they are built for different stages of a project and installed in very different ways.

For many homeowners, the practical question is not which window is "better" in the abstract, but which one fits the wall, the budget, and the condition of the existing frame.

That one design difference drives most of the other differences, from installation method to exterior trim work to how much disruption the job creates.
