When we moved in the original curtains in lounge were left. They are on a track pulley system but the house was painted before we moved in and I think the decorator removed them and did n't put them back correctly, as they have never drawn using the cord. What is the best way of establishing what is wrong ? We seem to have loose cords and the curtains get snagged on the track if we pull them manually so suspect something is askew or missing. It is a bay window with a window seat so rather awkward to look at in any detail.
