Hi Dave, Quite difficult for an amateur, renewing the chords and weights and maybe the parting and staff beads ( the ones on the inside keeping the sashes in. They can now be made totally draught and rattle proof. If you get a tradesperson to do it might cost about £200/300 per window. If you are thinking of doing it yourself you can't do better than watch a tutorial on utube. Jc
