The difference between a new build and a retrofit is not just schedule. It affects framing, flashing, trim work, permit questions, and the way the finished window performs for years.

Why New Construction And Renovation Are Not The Same Job

In a new build, the window opening is usually prepared before finishes are installed, which makes alignment and waterproofing much easier.

A renovation means the installer has to respect the existing structure and finishes. Sometimes that is a simple insert replacement, and sometimes it requires a full-frame tear-out to fix rot, poor flashing, or out-of-square openings.
