I have a new Andersen 400 double-hung window that's leaking air at the top left side, where the sash "jamb liner" meets the top of the window frame.

The right side has no such leak and the "jamb liner" is tighter to the top.

The left side has a small gap between this "jamb liner" and the top of the window.

Anyone familiar with Anderson windows?

- Can this "jamb liner" be adjusted for a better seal?
- Or, would you fill the gap (arrow) with some caulking?

Cheers,
Alketi

I would first talk to Anderson before attempting to fix it as they may send someone out under warranty. If anyone is familiar with an Anderson problem it would be them.

In the meantime roll up some insulation or wash cloth and put into the opening to keep out most of the air.

Last I dealt with windows like that the weathertight “seal” was the exterior casing and the weather stripping that sits against the window, not the top and/or bottom of that liner. Ron
