    What our London customers say

    Real homes, real noise problems

    The customers in this video live in the kinds of homes we work in every week: Victorian terraces near main roads, mansion flats above busy junctions and period houses under flight paths. Their stories describe the difference secondary glazing made to sleep, concentration and general comfort at home.

    Every project shown started with the same free survey we offer you, and every quote was given per window with no obligation.

    What results can you expect

    Noise reduction of up to 54dB is achievable in suitable configurations; actual results depend on the existing window, the surrounding wall and the quality of installation. The most common feedback we receive is that rooms feel calmer immediately, and that draughts and cold spots near the window disappear at the same time.
