Hi all,
I’m hoping someone with experience in window fitting or double glazing can offer some insight.

I live in a housing association property with wood-framed double glazing. The house is 14 years old, and we moved in right after it was built, so it’s relatively modern.

We’ve had recurring issues with the upstairs front windows spontaneously shattering. Three panes have gone bang and shattered over the years, the most recent one just two months ago. After a long wait and a lot of back-and-forth, the housing association finally replaced the glass yesterday—but the repair looks awful.

The window has wooden strips across the centre that divide it into two sections. On all the original windows, these strips were stuck and sealed with a thick black tape-like material that looked neat and professional. This time, however, they skipped the seal entirely and stuck the strips of wood directly onto the glass using some white substance, possibly sealant, putty, or paste. It’s uneven, messy, and clearly visible through the glass. It looks like a rushed job, and I’m worried it might not be good in the long run.

I’ve always understood that certain sealants or compounds shouldn’t be applied directly to double glazing, as they can compromise the integrity of the unit. Am I right to be concerned? I've attached 2 pictures one of the window they did yesterday with white stuff the other is what all other windows look like. Does this look and sound like poor workmanship?

I have little trust in the contractors my housing association use which makes me worry more.

I mean to give you a idea they turned up yesterday to replace upstairs window and didn't even have a ladder, we had to go and borrow one from a builder doing work on a property down the road so they could do window. They miss messured glass twice.

Any advice, especially from fitters or those familiar with glazing standards, would be really appreciated. I just want to make sure this doesn’t lead to another pane shattering down the line.

Thanks in advance!

Looks like the original was fitted with a double sided security tape , the replacement looks very much like white silicone but possibly CT1
Unless the 'silicone/ct1 ' comes into contact with the sealed units black butyl sealant then it will do no harm to the unit and just looks really messy
