I recently went out to give an estimate on refurbishing windows in a 1920's house in Stirling
The glass is in generally good condition. There are a few breaks and many of the tie wires have come away from the lead.
On the other side of the ground floor is a sitting room with a flat front that has a group of four windows. Two of these are hoppers. Both are bowed from the closing action and do not have any glazing bar to support the glass while closing.
The upstairs windows are of slightly different proportions to those downstairs.
The bathroom window which faces the street is odd in that it has only one leaded paned for privacy. Have the other two been lost?
