Golden Ratio Joinery Ltd provides specialist Sash Window Repair in Hampstead and across the surrounding London neighborhoods.

Our repair services include replacing worn-out sash cords, servicing pulleys, and addressing draughts. Hampstead houses a rich variety of historic cottages and sprawling Victorian residences. Our services focus on draught-proofing and slimline double glazing to improve thermal efficiency without altering the delicate historic aesthetic.
Many homes near Hampstead Heath, Parliament Hill, and Church Row suffer from rattling windows due to stretched or broken cords. We use high-durability waxed cotton cords and carefully re-balance the internal lead weights to ensure effortless gliding.
