Golden Ratio Joinery Ltd provides expert Sash Window Restoration Services for period homes across Hackney (E8, E9 & E5).
A full restoration is the best of both worlds for a Hackney period property — you keep the original, irreplaceable timber and glass that give the area's Georgian and Victorian terraces their character, while gaining windows that open smoothly, seal tightly and look freshly made.
Restoration goes far beyond a quick fix — we rebuild each window's performance from the ground up:
Old paint is stripped, decayed timber cut out and matching seasoned wood spliced in, retaining as much of the original window as possible.
New cords, serviced pulleys and correctly balanced weights mean both sashes glide and stay where you leave them.
Discreet seals end draughts and rattles; we re-putty and retain original crown glass wherever we can.
A durable microporous repaint protects the timber and leaves the windows looking immaculate for years.
With more than twenty conservation areas across the borough, restoring original windows is exactly the approach Hackney Council prefers — it protects your home's authenticity and value and avoids planning complications. For extra comfort, restoration pairs perfectly with a slimline double-glazing retrofit. Where a window proves beyond saving we build an exact replacement, and for smaller faults a simple repair may be all you need.
