Replacement / Pocket Window
Best for: Openings where the existing frame is sound and the goal is to replace the sash/unit with less disturbance to interior and exterior finishes.
Advantages

- Can preserve existing trim
- Often faster when the existing frame is in good condition
Considerations
- Relies on the condition of the existing frame
- May reduce visible glass area slightly
- Does not expose all concealed flashing or rot conditions
