Slim Cavity Units for St Austell properties
If Slim Cavity Units in St Austell were straightforward, there would be a stock size for it. Most of what we survey locally is granite fishermen's cottages, slate-hung terraces and modern coastal builds, which is not built to any modern module. The weather does the rest: the most severe salt and wind exposure in England here, and accelerated coating failure and salt crystallisation damage at glazing lines as the predictable result. What you are paying for is narrow cavities that perform while keeping the sightline historic.
A surveyor visits first and records the real dimensions, at several points on each opening. Send us sizes and a photograph and we will come back with a fixed written price.
One thing that catches people out here: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
