About from company website
City Sound Glazing has been a trusted name in secondary glazing since 1968, offering bespoke solutions for noise reduction, thermal insulation, and draught proofing. Founded by Derrick Smith and now led by his son Andrew, the family-run business prides itself on a high level of workmanship and customer service. They cater to both residential and commercial clients, including those in listed buildings and conservation areas, ensuring their services complement the existing charm of properties.
