What do I do with this gap around the window between the house and the brick mold?

The built in J trim works good with vinyl siding, I don't know what you do with that.

I'd just caulk around the sides and not the bottom, that way any moisture that did get in would have a way out.
What's up with the missing piece under the window?

It’s like that all the way around the window

If you cannot push the window in until it presses against the siding, doesn't that mean you ordered your windows too large?

If the window is the right size (it fits inside the rough opening), do you need to remove the interior trim and cut it to the new required width?

The window has a built in J trim, so the brick mold is an inch away of the flange:wink2:

That's funky.

Looking at the siding around the window, that seems more concerning to me than the gap in question.
