| If you have a removable interior stop, I'd suggest you install them from inside. If the stop is behind the casing, then you have everything basically correct installing from the outside.
I wouldn't use drywall screws... get yourself some 2 or 2 1/2" stainless steel screws. By all rights, your windows should have come w/ their own installation screws. And don't use silicone anywhere it will show where you will need to paint! |
