I removed the window trim and sill during decorating, we had a major draft coming through. All around the window was just gaps, no proper insulation.
So a lot of wall and sill just crumbled away.
What is best method to fix? I expanded foam around the window with low expansion foam.
Was thinking mortar to level of the sill then fit a new window sill.
Then square of the top and sides with plasterboard.
