Any suggestions for overcoming misted sealed units, is it possible to
drill hole and allow it to dry out?


Don't drill any holes in the window if it's safety or tempered
glass!!! Apparently the drilling holes trick only really works
if you get it when it first mists up. If there's been any beads
of liquid rolling down the inside then the water marks will
always be there.

Stuart Turner (I think) posted some years ago here about how he did
this, involving a vacuum cleaner and silca gel IIRC, it all seemed a
bit of palaver o me TBH. (Google Groups is your friend)

We have discussed replacing sealed units in double-glazing
a few times on here, and I have just paid to have a large
picture window unit replaced. I would consider DIYing in
the future, as the procedure itself was fairly straightforward.


Yeah it's not hard, though does need doing properly if they aren't to
fail prematurley. I really don't think it is worth the effort of trying
to repair one TBH, a replacement isn't really that expensive
