Our core clientèle are those seeking a high-end service with first-class products. Our level of training and performance is tailored to suit the demands of this particular market.
Modern living in one of the world’s most exciting cities has its drawbacks. London, with all it glory, is a very busy, noisy city and trying to live a comfortable, quiet life often seems impossible.
Secondary glazing is by far the most effective way of excluding environmental noise, making your office or home noticeably more serene.
A further application of secondary glazing is thermal insulation and complete draught exclusion. Old, single glazed windows are notorious for letting all the heat escape, resulting in unpleasant cold spots and very expensive heating bills during the long British winters.

Professional secondary glazing specialists you can rely on
Secondary glazing requires the installation of a new, fully functional and independent secondary window that will be fitted on the inside of a property (usually within the window surround that house the primary, external windows).
We can deal with all types of window styles (including Victorian Sash windows and Crittal windows), which might look beautiful but allow enormous amounts of noise, cold and dirt in from outside.
Our unique design mirrors the structure of your existing primary windows so that the secondary glazing is hardly visible once installed.
We offer a 12-year guarantee on all workmanship and materials. Just remember, we have been here for almost 50 years – so you are assured we will be here for the next 12 years to honor our guarantee to you.
