FWIW, I have a brick/block home circa 1961 with DH windows. I had them
replaced 3 years ago with Andersens, and have had no problems. The windows
were a complete tear-out, not just sash replacements.

Find a good installer with lots of references, and you should be ok.

Personally, I think if you have DH with grids, that's what you should
replace them with, otherwise your house looks funny.
