Retrofit Double Glazing for Launceston properties

The Retrofit Double Glazing we make for Launceston is set out from a survey, not a size chart. Because the area is mainly granite fishermen's cottages, slate-hung terraces and modern coastal builds, no two openings measure quite the same. Then there is the most severe salt and wind exposure in England, which reliably produces accelerated coating failure and salt crystallisation damage at glazing lines given enough seasons. Our focus on this is reworking the rebate so a sealed unit fits without bulking the section.

We check on site before committing anything to the saw, and we query what does not add up. Rough dimensions and a couple of photographs are enough for us to price it properly.

Bear in mind for this area: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
