Secondary Glazing Specialists in Harrow
Secondary Glazing for Harrow on the Hill, Pinner Village & Metroland Semis
Harrow is defined by two contrasting heritages: the medieval hilltop village of Harrow on the Hill, with its famous school and Georgian houses, and the archetypal 1920s and 30s Metroland suburbs of Pinner, Stanmore, Hatch End and Rayners Lane that grew along the Metropolitan line. Both have windows worth keeping — Georgian sashes on the Hill, leaded casements and bays in the suburbs — and both lose heat badly. Secondary glazing is the answer to each.

What We Solve in Harrow
Harrow School Environs
Properties around the Hill sit in one of outer London's most protected settings. Our fully reversible installations are accepted where any external alteration would be refused.
Leaded Metroland Casements
Pinner and Stanmore semis are full of small leaded lights that define their character. Secondary glazing insulates the whole window while keeping every lead line visible.
Metropolitan Line Proximity
Homes beside the Metropolitan and Jubilee lines experience frequent train noise. Our acoustic glass specification addresses the rumble that thin casement glass transmits.
