Should I caulk this window trim separating from the window

Question

I have windows where the trim is separating from the window at the bottom half of the window frame. Should I caulk it? Or is there a different solution?

I don't believe that I can nail in the trim given the window frames are not wood (per this answer).

Answer 1

Those are PVC window frames and the frames, glide tracks, are separating from the trim or were never installed pressed up tightly against the trim. If this is a cosmetic problem, you can put a small bead of caulk along there but sometimes, that just makes the "gap" more noticeable unless you're really good at caulking.. If there's no drafts coming in through there, I'd be tempted to leave it

Answer 2

Caulking wont work here.

Presume you are actually talking about the gap between the framing and the window (the bigger one). Not about the gap between the windows and the rubber seal.

If yes, loosen the quarter round framing up to the hight of the window.

Then push it towards the window and attach the framing.
