Retrofit Double Glazing for Helston properties
If you are looking at Retrofit Double Glazing in Helston, the timber is only half the decision. You are mostly dealing with granite fishermen's cottages, slate-hung terraces and modern coastal builds around here, so openings vary more than people expect. The exposure here is the most severe salt and wind exposure in England, which is exactly the condition that causes accelerated coating failure and salt crystallisation damage at glazing lines. The detail we will not compromise on is reworking the rebate so a sealed unit fits without bulking the section.
A surveyor visits first and records the real dimensions, at several points on each opening. Send what you have, even if it is only a phone photo, and we will take it from there.
Local factor worth flagging early: Cornish exposure grades mean specification should assume worst-case wind-driven rain.
