Golden Ratio Windows provides expert Sash Window Repair across Hammersmith and the surrounding London Boroughs.
We specialise in sash window repair services for traditional and period properties. Restore the timeless beauty and smooth functionality of your traditional sash windows with our dedicated repair team.
Our craftsmen address issues ranging from annoying draughts and rattles to repairing damaged timber frames and replacing worn-out sash cords.
Hammersmith is home to a wealth of period housing, particularly characterized by Victorian cottages and grand riverside terraced houses. Many of these properties still feature their original box sash windows. Our repair service focuses on maintaining this historic character—whether that involves surgical timber splicing on rotten sills near Hammersmith Bridge, King Street and the riverside pathways or overhauling rattling sashes to improve energy efficiency.
Our team provides essential sash window repairs in London. From Hammersmith (W6) to neighboring areas, we fix draughts and broken cords to keep your heritage windows functional.
We have helped hundreds of London homeowners upgrade their inefficient single-glazed windows.
