Refurbishing your sash cord windows is key to keeping warm and reducing your fuel bills

You’ve probably done a few things to address the issues with your sash cord windows, like trying to plug the gaps to keep the heat in, jamming them with folded paper or cardboard to reduce rattling, and even resorting to layering up just to stay warm (even in bed!).

It’s important to realise that the inefficiency of your wooden sash windows is not your fault. Single glazed Victorian sash windows and  Georgian sash windows were never designed to meet the challenges of modern day living.

It’s no wonder you may well be confused about the options of either repairing, or fully replacing them.

Big double glazing window companies, who use subcontractors, prioritise full unnecessary replacements. Smaller contractors primarily offer poor, patch-up repair services.

Now you have the perfect opportunity to refurbish, draught-proof and carry out any sash window repairs that may be needed.
