Hi,
Appologies for the off topic post but I thought the people in here may have an answer.
About three years ago Anglian replaced our doors and windows with double glazed units. The back door has been a problem ever since because if we leave it open for any amount of time (say > 20mins) it drops making it hard to close the door again. I then have to lift the door up and then close it.
We have called Anglian out several times and all they do it just put a plank of wood under the door and lever it up, this is obviously not fixing the cause of the problem. They came out last week to fix it again and last night I was back to having to pulling the door up to close it.
Is this a common problem with double glazed back doors? Presumably the hinges are not strong enough to take the wheight of the door?
Thanks Andy
