Hi All,
Looking for some help on a problem I’ve been struggling with for about 5 years. 2011 I had new double glazed timber sash windows fitted to replace old draughty single glazed sash. I had the whole box replaced and masonry, architraving made good etc. The work seemed to be good. I used a local Fensa registered joinery company with a sound reputation. All in I had about 9 windows fitted - no problems with any apart from one, the bay, which has leaked ever since fitting.
Long story short, I’ve had builders and other glazing companies come and have a look at it and the masonry, sill and all surrounding areas are sound - no sign of where ingress could be occurring. But, whenever it rains for a long period of time, a damp patch appears on the wall underneath the sill. Spoken to the window company about twenty times, they can’t see any problem. I had my builder place a hose against the window and its pretty obvious that water is coming through between the parting bead and the masonry. The window company applied some sealant to the almost non-visible / non-existent gap between the parting bead and the masonry and the leaks stopped.
The problem is, as soon as the weather changes - i.e. we get a warm period or a wet period etc, the sealant cracks or moves and the leak begins again. I don’t understand it, as all of the other windows that were fitted don’t leak and they don’t have any sealant applied. It’s just this one window. All of the windows have weather strips - a plastic strip With a brush strip in the gap between the parting bead, so the gap is almost non existent but obviously water still gets through on this one window.
What can I do? Should I pushing to get them to replace the entire box and start again - they seem very unwilling and I can’t believe it’s necessary on what was / is a brand new window, but I’ve ran out of ideas and they never had any in the first place, other than applying flexible sealant.
any help appreciated.
