Sash Windows for Harrow properties
The Sash Windows we make for Harrow is set out from a survey, not a size chart. The housing here is largely Victorian and Edwardian terraces, mansion blocks and post-war infill, and that shapes what will actually fit. Add high pollution load and sheltered urban humidity to that and paint failure on south-facing sashes and rot at the bottom rail becomes the usual trigger for replacement. What you are paying for is sliding sashes that run smoothly and hold position without slamming.
The site visit comes first, because assumptions made in an office get paid for on site. Ask us for a figure and you will get one, with the lead time stated alongside it.
A detail specific to this area: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
