I moved into a new house about 18 months ago which has wooden double
glazing. The house is only about 9 years old, but the previous owners
had fake lead diamond effect stuck all over the windows and this,
combined with poor maintenance, seems to have resulted in the breakdown
of many of the sealed units (misted sealed units).

How does the fake lead flashing result in blown units? Also, how does
'poor maintenance' result in blown units? What preventative maintenance
is there which prolongs the life of sealed units?


Anyway, the question is: am I likely to be able to replace just the
sealed units (the glass)

Yes, there will be beading holding the sealed units in, either on the
inside or on the outside. Removing this beading will allow you access to
the sealed units.
