    I want to install this door, 850 x 2100mm aperture size required. The hole from the existing back door is 890 x 2060mm.
    Whats the easiest way of making the hole bigger? (scared I'll bring the house down on top of me)

    does the new frame have a cill that you could do without? that would get rid of 40mm in height and then take 10mm of head of frame with planer.
    if not what lintol is above opening?

    A Lintol is the concrete or steel beam over the door or window opening, that supports the wall above.
    In a really old house it may be a timber such as oak etc.
    DO NOT try to cut, plane or trim the lintel unless you want a collapse of the wall!

    You shouldn't really cut or plane a upvc pre-fabricated door or frame. It is all part of the structure and strength of the system.
    Also, you might just cut through the plastic and damage the water tightness. The frames are hollow.

    Well i installed a upvc front door last year,
    and the manufacturers instruction that came with it, said " there is a 10 mm trimming surplus around all sides of frame" so trim i did, with my electric plainer and all is well!!!!

    Three points:
    1) DO you really think that the 5mm lip around the edge significantly affects the strength of a frame that is (or should) not be bearing any load?
    2) If you are likely to plane all the way through a upvc frame you shouldn't be allowed out on your own, let alone let loose with power tools
    3) How do you propose you fit a window in a gap that is 5mm too small? Throw it away and order a new window?
