I live in China. Construction is largely handled by unskilled migrants, and one cannot just call up a specialist contractor to fix a major issue.
I've got a window that was not properly sealed when the apartment was built, and which has become a major vector for mold and moisture. So much so that ice builds along the edges in the winter and water occasionally pools in the summer.
Fix it myself, from the inside only, with tools and materials readily available at Home Depot-type stores. (i.e. - nothing too exotic)

The problem window (north facing, to make things even more "fun"
Window blueprint, somewhat to scale.
Mold and plaster damage around the left concrete column. Interior is to the left, exterior to the right. The plaster is about 2MM thick and applied directly to the concrete, with a latex interior paint double coat. I don't know what exact material was used to seal the window in place.
The plaster is steadily falling off the wall due to the damp.
More falling plaster...

Best course of action?
I figure there's no getting around stripping all the plaster off the wall around the window, and that's fine. The questions I have in mind are:
- does the concrete need a sealant before fresh plaster & paint are applied?
- can the window frame be effectively resealed from the inside only?
- is there hope for success? or will this always be a bastard unless we can find a competent renovator who can fly? (we're on the 4th floor)
EDIT - photo captions don't work? I've added them manually as paragraphs...
