I have been looking after sash windows for over 17 years now and In all this time I have only needed to advise 4 clients that they NEED full replacements.
This is great news: a full box sash window is a lot of joinery and average sized windows currently cost £3500+vat
Option 2 – Industry Standard double-glazing upgrade
The industry provides replacement sash leafs but does not do a good enough job of protecting the original box frame and creating a quiet, smooth sliding and draught-proofed window. The market operates at just above £2000 incl vat per window.
