City Sound

City Sound is a family-run business established in 1968, serving Central and Greater London's commercial & residential clients. We can tackle all window designs, and in particular are often asked to sound proof, or draught/heat insulate, Victorian sash windows which can look beautiful but may be noisy, dirty and draughty. Our unique design mirrors the structure of your existing primary windows so that the secondary glazing is hardly visible once installed.

We welcome projects in listed buildings that require a high standard of workmanship and expertise. Our clean and efficient service carries a ten-year guarantee on both workmanship and materials.
