UPVC external door

[tooly]

I need to raise the external front door a few mill to clear some interference between the bottom of the door and the frame at the bottom. Is this possible? if so how do i go about it? Thank's. Tooly.

you need to take the whole frame out carefully and raise it.There are ajustments on the higes to align the door but not to raise it.It would pay to have it refitted by a proffesional
