I have been trying in vain to find a suppler of sash weights. Where can I get them?
All the suppliers I know of are listed in the directory. Other possibilities worth pursuing locally are architectural salvage companies, lead merchants, architectural ironmongers (unlikely, but ask just in case) and scrap merchants just in case they have any they haven’t yet sent for smelting. Be cheeky and ask uPVC window companies or their fitting teams if they have removed any recently, and if so what they do with them. Look for old established building firms with untidy yards!
