Sash Window Replication for Harrow properties
Half the Sash Window Replication problems we fix in Harrow started as a sizing assumption. Property here runs to Victorian and Edwardian terraces, mansion blocks and post-war infill, and each of those brings its own set of dimensions. 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. The value is in copying the surviving original rather than approximating it, not in the timber bill.
Nothing goes into manufacture until a surveyor has checked each opening on site. One call is usually enough for us to tell you roughly where the price will land.
One thing that catches people out here: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
