Slim Cavity Units for Helston properties
If Slim Cavity Units in Helston were straightforward, there would be a stock size for it. Because the area is mainly granite fishermen's cottages, slate-hung terraces and modern coastal builds, no two openings measure quite the same. Add the most severe salt and wind exposure in England to that and accelerated coating failure and salt crystallisation damage at glazing lines becomes the usual trigger for replacement. Everything we do here comes back to narrow cavities that perform while keeping the sightline historic.
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.
One local point to factor in: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
