I'm in the midwest US and looking to replace my aluminum windows with
vinyl custom-made argon low-e. I don't know pricing - can anyone help
with a guesstimate on window price with installation for a roughly 4'
x 4' opening ? Remove the old aluminum, haul it away, install new
custom-sized vinyl and caulk it.

Or, if you have specifics - a custom vinyl window with a pane in the
middle and sliders on each side, opening is 8' wide and 20" tall.

House is brick. Vinyl windows are considered high-end for this
neighborhood.

I don't mind paying for a decent job but I got nothing to go on and
it's a PITA to get quotes.
