Slim Cavity Units for Doncaster properties
There is no standard version of Slim Cavity Units in Doncaster, which is rather the point. Local property is overwhelmingly steel-era terraces, interwar council stock and stone village housing, which is why we never quote from a catalogue. cold inland winters with prolonged damp is the local complication, and condensation-driven decay on single-glazed units in unheated rooms is what it eventually causes. The value is in narrow cavities that perform while keeping the sightline historic, not in the timber bill.
The survey happens before manufacture, which is why our units fit without packing or trimming. Photographs and approximate sizes are all we need to start.
Local factor worth flagging early: large volumes of pre-1919 stock make sash repair the dominant enquiry.
