Retrofit Window Installation
I've purchased my retrofit windows and am getting ready to install. My existing aluminum window frames have drip edges top and bottom which I removed with tin snips. The aluminum frame still sticks out from the stucco about 3/16" all around. The plastic fin of the retrofit window has a return of about 1/16". When I place the window in the opening I have a gap all around of between 1/8" to 3/16". Do I need to grind or cut the aluminum frame so the plastic fin contacts the stucco or can I fill this gap with caulk? If I need to trim the aluminum, what is the best method?
