I have a slight gap at the top of my UPVC Patio Doors. I can see daylight and feel a draught. Is it possible to adjust the door so that it closes properly?

hi there,the door needs jacking up on the wheels by the sound of it,worst case is that the wheel has broken,if the patio is still running smooth then the wheel should be ok.how to adjust it : you need to open the patio door and look at the bottom of the track wot the patio is sitting or running on and there will be a screw attatched to the patio wheel which isent easy to see,you will need a long positive screw driver to reach the screw and just start turning the screw untill the patio starts movingt up or down,then you can adjust patio to where you want it.hope this helps you

If its slider there shouldn't be a gap as it fit around frame. If its french door you need toe and heal doors again if its slider your lucky it not fell out raise the wheels but dont do it alone have some one hold door if you turn wrong way door could fall out
