Slim Cavity Units for Merton properties
We take a fair volume of Slim Cavity Units work across Merton, and almost none of it repeats. Most of what we survey locally is Victorian and Edwardian terraces, mansion blocks and post-war infill, which is not built to any modern module. high pollution load and sheltered urban humidity is the local complication, and paint failure on south-facing sashes and rot at the bottom rail is what it eventually causes. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. Rough dimensions and a couple of photographs are enough for us to price it properly.
Something particular to this area: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
