Misted Double Glazing Repair In Glasgow

A misted window is the visible sign of a failed seal. Every double glazed unit is manufactured with a hermetically sealed air gap between the panes, which acts as a thermal barrier. Over time, the perimeter seal can degrade due to age, heat cycling, or exposure to the elements. Once the seal breaks, external air and moisture are drawn into the unit. As temperatures change, that moisture condenses on the inner surfaces of the glass, producing the familiar foggy appearance associated with blown double glazing. In Glasgow’s climate, with its frequent rainfall and temperature variation between seasons, this process is accelerated in older or lower-specification units.

Misted glass unit replacement in Glasgow involves removing the failed sealed unit from the existing frame, measuring and cutting a replacement double glazed unit to fit, and fitting the new unit with fresh seals and gaskets. Crucially, the frame itself is left in place. Glasgow’s housing stock includes a significant proportion of period properties where frames, particularly timber sash frames in the west end or stone surrounds in tenement blocks, are worth preserving. Because the fault lies in the glass unit rather than the frame, replacing only the sealed unit is the correct, cost-effective solution. Our vans are stocked with glass that can be cut to size on site, so misted window repair in Glasgow is completed efficiently without the need for a return visit in most cases.
