We moved in to our house 5 years ago and soon after started experiencing some of the triple glazed panels started to show condensation in them. After doing some digging in the paperwork that the previous owners left us, we found that these windows were sold and installed by SEHBAC. After then having to pay to transfer the remaining warranty to us, they started replacing the panels as more continued to fail. Over the course of the last 4 years we have had to replace 5 or 6 (I can't remember anymore as each time was a nightmare with one pane taking 8 months to be replaced!!) The remainder of the warranty has now run out and due to the extremely piss poor service we received from that company, we won't be going back to them. I have looked online and found that you can buy these panels direct from other companies but I am worried that the quality won't be great. Can anyone recommend a reputable company to use to buy these replacements and I can fit them myself when they arrive?

The replacements I’ve had from modernupvcwindows.co.uk seem to have been OK so far, though the larger panes did have to be remade a couple of times due to fingerprints on the inner pane.

 

have just had another one start steaming up, but won’t be replacing til a couple more go to make it make sense delivery charge wise. Around 9 years old that one. I wonder if triple glazing is more prone to the units blowing?

Thanks for the reply @MikeGrahamT21 .. Not sure regarding triple glazing over double glazing, but we had the rest of the house done with double 4 years ago now with no issues so far but probably too soon for anything to happen with those.. Good point on waiting for more to save on delivery, i think we have 2 to get done now so will get a quote and go from there.
