After selecting Origin Bifold Doors i was introduced to this company by the Origin website as my local supplier. The doors were fitted in 2017 and all seemed good until the weather turned colder and I started getting condensation on the inside of the threshold and I noticed that the foam gaskets had shrunk. I called Ekco who replaced the gaskets under warranty and said that would cure the condensation problem. Unfortunately it didn't and the gaskets continue to shrink and have had to be replaced almost annually. I've had several different excuses for the condensation but in an effort to cure the problem the doors were removed and refitted in February this year which we hoped had done the trick but again as the weather turned the condensation came back, the foam had shrunk and I also noticed a gap between the threshold and the side wall had opened up and water was pooling on the outside of the threshold. This suggests to me that something has sunk so I again contacted Ekco who responded by saying as the doors had been refitted there was nothing else they could do and I've had too many visits so they would only come back if I paid a £250 fee. They were happy to order new foam under warranty but I either have to fit it myself, pay someone else or pay them £250. They now also say that the condensation could be caused by the construction methods of the extension and the foam shrinkage could be within tolerance. So if the extension is not suitable for the doors why was this not found on the initial survey or the initial fitment or even the second fitment? And why does the foam gasket manufacturer state that the foam will only shrink if it is incorrectly fitted or overstretched? I will not be paying these jokers a single penny more. The number of visits is down to the poor fitting and has been an ongoing issue from the start. I've requested a copy of the fitting warranty twice but been ignored both times and it is not available on the website, nor are they members of any trade association so you are basically at their mercy. Do yourself a favour and stay well away from this company, they may be fine when things are going well and they will happily take your money but when things go wrong they don't want to know (unless it can be fixed with a couple of cans of expanding foam and some silicone).
