I need to replace a misted DG unit in a wooden frame. The unit is fairly
small (550x500mm) and, unless I'm missing something, the job appears simple,
o remove beading
o remove old pane
o set sealed unit in silicone
o replace beading
Am I missing something? I ask because of the prices being quoted for the
job - c. £200 and each glazier I've spoken to has quoted within £20 of this
price. I was quite stunned - so I assumed that the unit itself is expensive.
But I've just been told that I can get one for about £20. Last single pane
I had replaced of a similar size cost about £60 including the glass and the
job took the glazier about 30 mins. So, £180 for about an hour's labour
incl measuring up. Even call it 2 hours - £90 an hour. Hmmm.
Why such a difference in price between single and double glazing in a wooden
frame? I rather suspect rip-off Britain at work.
TIme to do the job myself I think. Unless someone can tell me there's more
to it than I think.
Assuming I do it myself, what tolerance is prudent to allow in the
measurements for the unit - is it simply measure the frame (less beading)
and subtract 2 mm all round?
