We replace cloudy or misted units
A fogged up double glazed unit with condensation between the glass panes looks unsightly and is caused by a failed seal, compromising the thermal performance of the window. At CGS we can replace just the glazed unit rather than the entire window, potentially saving you hundreds of pounds.
