Plaster repair around window replacement installation
A replacement window was installed in the corner of a room of our 1950’s house. There’s a 1(1/2)” wide gap from the side of the window to the corner wall. Most of the old plaster and drywall is gone, but a metal mesh is still there with a bit of plaster. What’s the best way to fill the gap? There’s foam around all the window edges, but the foam doesn’t extend to the interior wall surface. Should it? If not, what should the gap between the foam and the interior wall surface be filled with? Also, how should the gap between the windows be finished? Currently a piece of rigid foam is screwed into the gap. Thanks for your input!

You could fill with joint compound-I'd not use bucket mud, but would use something like Durabond-shrinks less, dries HARD. Use the window jamb as a screed. If it's covered completely by the casing, it's not necessary to fill (as long as the air sealing detail is good), not needed but will give a backer to the casing so it doesn't get sucked back when nailed off.

Not necessarily. Could add more or leave as is if the air sealing has been accomplished.
Also, how should the gap between the windows be finished? Currently a piece of rigid foam is screwed into the gap.
I'd use a thin (a bit less than the casing where the two would meet) mullion that has the same reveal on the jambs as the casing. Thinner so it dies into the casing, and doesn't protrude beyond the casing edge. Round over the sides, or simple lightly sand the sharp edge.
Thanks for your input!
You're welcome.
The above assumes you are putting casing around the window.
