Retrofit Double Glazing for Lewisham properties
Retrofit Double Glazing in Lewisham rewards patience at the setting-out stage. Property here runs to Victorian and Edwardian terraces, mansion blocks and post-war infill, and each of those brings its own set of dimensions. Set against high pollution load and sheltered urban humidity, most joinery here eventually shows paint failure on south-facing sashes and rot at the bottom rail. What we concentrate 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.
A detail specific to this area: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
