Our fitters advice is to check the wheels on the sliding door, if the wheels are broken or cracked then there may be too much give which is why the doors are lifting and moving in bad weather. We have photos which show how much of a gap there should be between the wheel and the metal runner which we could send to you. If you would like us to email the photos to you please call our Customer Service Department on 01457 821966 between 9am & 5:00pm.
