Slim Cavity Units for Havering properties
The Slim Cavity Units we make for Havering is set out from a survey, not a size chart. Local property is overwhelmingly Victorian and Edwardian terraces, mansion blocks and post-war infill, which is why we never quote from a catalogue. Because of high pollution load and sheltered urban humidity, we see paint failure on south-facing sashes and rot at the bottom rail more often here than in most of the country. Our focus on this is narrow cavities that perform while keeping the sightline historic.
We survey before anything is cut, so the schedule reflects the opening as built rather than as drawn. Send us sizes and a photograph and we will come back with a fixed written price.
Something particular to this area: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
