Slim Cavity Units for Penarth properties
We take a fair volume of Slim Cavity Units work across Penarth, and almost none of it repeats. Around here it is valleys terraces, Victorian maritime villas and civic Portland stone frontages, and that alone rules out anything bought by the pallet. The weather does the rest: very high rainfall with strong Atlantic and Bristol Channel exposure here, and prolonged wetting decay and finish failure on valley-facing elevations as the predictable result. This is really a job about narrow cavities that perform while keeping the sightline historic.
Nothing goes into manufacture until a surveyor has checked each opening on site. Give us the basics and you will have a written figure, not a range that moves later.
A local consideration we always raise: valleys terraces share a repeating bay and sash format that suits batch manufacture.
