It doesn't feel like a contractor thing.

Why not? What does your contractor say?

Who ordered the windows?

There is also an issue with the finger pull and its placement.

What finger pull? What's wrong with its placement?

Something is missing from making it look normal. The contractor, who ordered windows, is suggesting an insert with a lip up and onto the sill.

The pull placement may preclude getting the operators fingers in there. A metal strip is in between the windowpanes. Because of the screws placement will that be a warranty issue.

I know that this is an Andersen issue. I have also contacted them.

Have you ever run up against these things?

Before anyone shaves, trims or re-cuts a sash, measure the gap at each window in three spots with the sash fully closed and locked, and photograph it next to a tape or level. A gap of about an inch at the bottom rail usually means the sash is not reaching the sill and weatherstrip, so the cause is more often the insert height or how the unit was set in the opening than the sash itself. Ask the installer to walk you through the adjustment on one window and show you the closed position before the rest are finished. Send Andersen the measurements and photos in writing now, since a fit problem on a new install is normally a warranty item and a dated paper trail helps. For the finger pull, check that your fingers fit between the pull and the frame when the sash is open, and ask for a written fix rather than drilling new holes yourself, because that can affect the warranty.

Have you heard of this issue?

Something is missing from making it look normal.

I'll suggest the windows are too tall, or not installed correctly, or both.

The bottom of the window need to be raised.

It's definitely a contractor thing.

Someone will need more pictures, including the outside, and information about the installation and specific window to keep guessing.

Yes, a gap that size at the bottom rail usually means the sash sits too high relative to the sill, which points to insert height or how the unit was set in the opening rather than something a refinisher should fix. Before anyone trims it, compare your measurements and photos with Andersen's installation specs for the A-Series, and ask your installer to show you the closed position on one window. If the spec is off, Andersen's warranty process is the right route.
