Double glazed door sticking

[Sarahh5362]

My porch door which is about 5 years old has started to stick when trying to slide it open or closed. I have put grease on the end of the frame and this has helped a bit but it still sticks - it was fine up until last week. It just does not seem to be running along the end of the frame properly - any suggestions

Sarahh5362,
You need to get someone in to check the adjustment of the rollers on the bottom of the door and to make sure the top track is secure.
