Retrofit Double Glazing for Islington properties
The hard part of Retrofit Double Glazing in Islington is not the making, it is the measuring. The housing here is largely Victorian and Edwardian terraces, mansion blocks and post-war infill, and that shapes what will actually fit. The weather does the rest: high pollution load and sheltered urban humidity here, and paint failure on south-facing sashes and rot at the bottom rail as the predictable result. The part that matters is reworking the rebate so a sealed unit fits without bulking the section.
Each opening is recorded individually, since a terrace of identical houses rarely is. Photographs and approximate sizes are all we need to start.
A local consideration we always raise: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
