Secondary glazing - reduces traffic noise by up to 80% and once fitted is hardly visible.

City Sound is a family-run business established in 1968, supplying Central and Outer London businesses & private clients. We can tackle all window designs, and in particular are often asked to do sash windows which can look wonderful but may be noisy, dirty and draughty ! Our unique design mirrors the structure of sash window so that the secondary glazing is hardly visible once installed.

We specialise in listed buildings requiring a high standard of workmanship and expertise.

Our clean, fast and efficient service carries a ten-year guarantee on both workmanship and materials.

CURRENT ASSIGNMENTS include: Tate Britain, BP Head Office, Westmister County Hall.
