Hi, it's times like this when i feel i am just pretending to be an adult because have no idea what to do. one of our upvc window handles does not work properly. it has come loose, will no longer lock and cannot really open and shut. the screw keeps falling out and the thread will not hold it. the handle is wonky. the other ones are going the same way - wonky handles - but can be open and closed. we can leave teh window closed but occasionally it blows open!
we bought the house new 7ish years ago, so it is still under nhbc but don't think this would be included. no idea who made the windows.
who exactly could fix this and do we need a whole new window? (prays not)
