Golden Ratio Windows provides expert timber joinery across East London.
If the existing frames are completely rotten, repair is not an option. You need Sash window replacements in Hackney to stop water getting into the brickwork. We manufacture exact timber replicas in our workshop.
The outer box frames are constructed from Accoya wood. This prevents future rot. The moving frames hold modern double-glazed units. This stops cold drafts completely.
Many streets in the borough are protected. When providing Sash window replacements in Hackney, we must match the original glazing bars. We copy the exact Victorian profile. This ensures you meet all local council requirements.
We do not use plastic frames. Every window is painted by hand to look authentic. The internal weights are correctly balanced. The windows glide easily and do not rattle.
We visit the property to take accurate measurements. We provide a final price based on the amount of joinery required. There is no hard sell. The price covers the complete removal of old wood and the fitting of new units.
If you require someone to handle your Sash window replacements in Hackney, use our contact page. We provide a full FENSA certificate upon completion.
