On a window like this you would normally remove the two side beads first but with this being
such a small window it is very difficult. So in order to get enough flexibility to
remove the beads I'm going to take the bottom one out first, then the two sides
and then the top. Normally you would remove the side ones first and then bottom then the top.
To start off with to get a gap I'm going to use this
6-in-1 decorators tool, which is very sharp. But it won't actually damage the beading.
If you put something smaller like a screwdriver and you try levering it,
there is a chance that you will damage the beading. So I'm going to start off by
forcing that into the small gap there.
You can see that that has given us a tiny gap, we can now take one of the plastic
trim removal tools like so, then we can also push that into the gap.
We can now take another tool and just go along a bit further. You can see that the beading is now bent in the centre there
so we can now get our tool in there
and remove that piece of beading.
we can then insert the tool into the bottom there and lever out the beading.
Now I will take the scraper again and push that into the gap and then I'm going to lever out the bead.
Once I get it partially out I can use the plastic removal tool .
Then finally we need to remove the top bead. When you remove the top bead
the window is obviously going to fall, so you do need to be ready to hold it.
Once we have levered out the corner, we can then get hold of the beading and just pull that straight out.
I do need to be really careful with this window as it is in a lot of pieces. I will just lever that out,
and we can carefully bring it to the ground and measure it. So we need to measure the overall
width exactly, which is 565mm the overall height which is
295 mm. We now just need to measure the actual
thickness of the unit. This one is 24 mm. If you look at that glass
you can see that it is patterned so we need to ensure we get the same pattern so on
the inside it's patterned like that. So if you take a picture of that using your mobile phone,
take that with you and tell them that you want that matching up.
Your glazier will be able to get that glass for you , or something very close to it.
It is going to take about a
week for the new unit to be made so we do need to put the old unit back in.
So carefully lift it back up and then place that back in position.
This unit is in a very bad condition it is broke into hundreds of small pieces.
So I'm now going to put the top bead back in. Now some of these go in differently to others bit and
it can be quite difficult getting some of them back in.
So I'm just going to get that in the corner
See that pushed back in there quite easily. Sometimes it is more
difficult. Normally you put the top in and then the bottom and then the two sides.
As this is such a small window I'm going to put the two sides in first.
In fact because this window is not going to be used, it's in an ensuite
bathroom I'm actually going to put this side bead in to hold it and leave the bottom beading out
to make it easier when we come to fit the new unit.
I'm just going to push this one in then there is absolutely no chance at all of this unit falling out.
Before putting the new unit we are going to check it's clean on the inside. So if it is dirty
it is a good idea to clean it with a damp rag. You may also find some
glazing packers at the bottom. If you find glazing packers you do need to leave those in.
If you have never seen a glazing packer before they look like that. You can now take the new unit and
carefully put that in position. If you've got patterned glass like this
the pattern normally goes on the inside. The plate plain glass normally goes on
the outside. You can make it a bit easy to get the seals back in them by spraying them
with some all-purpose silicon spray. Then take the top seal and get it in in the corner
and then push that all the way home . If you are struggling getting the beads in
you can push them in using a block of wood, like that. Simply use that to push
the beads back in. Because this is only a very small window the side pieces are
difficult to get back in so I'm going to put these in next. So I just need to push that up
into the corner until it clicks all the way in and then we'll push that one right
up into the corner.
The last beads going to be difficult to get in because of the size of the
window, so I'm going to push this corner all the way in,
get that in there as far as I can, and then bend the bead so that I can get the other one in the other corner.
Then it's simply a matter of pushing that into position, and that will snap in like so.
So that's how to replace the unit in a double glazed window it's not at all difficult.
That unit actually cost £15 which is very very inexpensive.
