I have some Marvin casement and slider windows to trim out. I’ve trimmed other windows but not ones that already have a sill. I want to add a sill and I want to make sure the way I am doing it is the right way.
For both the sliders and the casements I plan on gluing and screwing a sill extension onto the existing sill and then adding the rest of the trim. Is this how the sill should be added?

Short answer is yes.
What you have are jamb extensions. I might not try to flush up the sill to the bottom extension. A slight reveal should bother no one.
If both sash slide, you have the option of biscuits and clamps so no plugs for screws. Same with the casements.
