Hello Linda,

Yep, looks like the seal has failed on your 1/2 circle top window, as well as the grids having collapsed. Easiest and most cost effective way for you handle this is to find a glass replacement company/someone to replace the insulated glass unit, aka IG UNIT.

This would entail NOT removing the window frame itself, which can be way more involved, especially if this window is mulled (industry term for attached) to a window unit below it, which is usually the case. The replacement of the IG unit by itself will save you a big chunk vs the entire window. Looks like it is about 48" wide, just make sure they get the new grids to align with the window below, if there is one.

Good luck!

In Georgia a wall retaining over 48" grade requires an engineers stamp.

You might consider terracing and have two or more lower retaining walls. Be aware of hydrostatic pressure and provide adequate weepers to deminish concern for hydrostatic pressure. Good Luck!

I would work backwards and figure out what you can do abou the moistue.  Do downspouts dump water right on the foundation or do they do what they are suppose to do which is move water downhill and at leadt 36" away.

Look into a sump pump at 48" deep

I think it is a good idea to deal with the cause of the moisure intrusion before figure how to cover it up
