A few years back, I replaced some old and balky wood sash windows with
vinyl casement ones. The company that installed them did a good job
of showing me how well their windows were constructed, and so far
they've held up well.

But I just noticed that the sills are flimsy vinyl moldings, attached
to the window frames only by caulking, which has come loose. Is there
a good way to reseal these? Or need I bite the bullet and get real
sills installed?

And by the way, if you are having vinyl windows installed, don't stop
at checking the quality of the windows themselves--check the sills,
too.

IIRC, Certainteed has a line of PVC trim and such that could probably
solve your problem. Check their online PDF catalog.
