Slim Cavity Units for Barnet properties
We take a fair volume of Slim Cavity Units work across Barnet, and almost none of it repeats. Property here runs to Victorian and Edwardian terraces, mansion blocks and post-war infill, and each of those brings its own set of dimensions. With high pollution load and sheltered urban humidity in the mix, paint failure on south-facing sashes and rot at the bottom rail is a question of when rather than whether. The value is in narrow cavities that perform while keeping the sightline historic, not in the timber bill.
The measuring is done by the people responsible for the fit, which concentrates the mind. Photographs and approximate sizes are all we need to start.
Worth knowing locally: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
