Retrofit Double Glazing for Penzance properties
If you are looking at Retrofit Double Glazing in Penzance, the timber is only half the decision. Property here runs to granite fishermen's cottages, slate-hung terraces and modern coastal builds, and each of those brings its own set of dimensions. Set against the most severe salt and wind exposure in England, most joinery here eventually shows accelerated coating failure and salt crystallisation damage at glazing lines. Where we put the effort is reworking the rebate so a sealed unit fits without bulking the section.
The survey happens before manufacture, which is why our units fit without packing or trimming. Tell us the problem rather than the solution and we will advise on both.
Bear in mind for this area: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
