I had a contractor come install 4 of these windows for me.
He’s an older guy who I believe just does this to keep busy post retirement. The labor costs were very cheap.
When I went upstairs afterwards to look at the windows I immediately noticed what looks to me like a big problem with them.
So essentially these new windows are inserted into the old ones. However they aren’t the same thickness and there’s a gap between the front of the new window and the front of the old one.
Wouldn’t this gap just fill with water and run down my walls eventually and rot out? I can see pink insulation in the gap and it’s seemingly just exposed to the elements.
