New Construction Windows vs. Replacement Windows: What’s the Difference?

The pricing and process for windows make a lot more sense once you understand what the wall needs behind the finished trim.

New construction windows are designed for openings that are still open to the framing, or for a wall that is being rebuilt enough to expose the studs.
