Replacement Windows for a Baltimore Rowhouse Rear Addition

Why Rear Additions In Baltimore Rowhouses Need A Different Approach
When people talk about replacement windows for a Baltimore rowhouse rear addition, they are usually dealing with a space that was framed, flashed, and finished under very different conditions than the original masonry shell.

Permits, Historic Review, And Cost Questions
