Re: Window Repair
It is not uncommon for the ropes to break on sash windows. There should be a panel on one side of the jamb to access the weight pockets and retrieve the weights and then install new cords. If there are no access points, then pull the interior trim off the window to get to those weight pockets.
Another option, though not a restoration, is to use a spring shoe, which slides between the window and the jamb to wedge the window at any point along the opening. The spring show slides with the window and just provides tension to keep the window from free falling.
Sash cord is available at any hardware store, particularly in older neighborhoods where this type of thing is more common, as opposed to a big box store that only caters to what is cheap and currently available.
