Morning all,

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 wouldn't have DIYed this
job because of (a) not having seen it done before, (b) the
height of the window off the ground, and (c) not having any
experience of ordering sealed units.

I would however consider DIYing in the future, as the
procedure itself was fairly straightforward.

I have put before/during/after pictures on a web page, along
with a brief description of the process involved, he
