    Trim back dpc
    Seal gap with sealant
    Glue/tape a bit of small quad along (smooth anthracite grey)
    Seal again giving double seal

    You should have weep holes on the front of the frame, this is your drainage.
    Google "UPVC quadrant trim"

    You would of been better of going down half a brick and having a sill

    I know a cill would have been better.
    There are weep holes along the bottom frame.


    The quadrant idea sounds good. Like the idea of a double seal. Thanks for the help

    If you seal along the face of the frame and the holes are on the bottom water will get back into the internal floor, you'd be better of buying a cill and dropping a brick course. Anything else would just be a bodge and you'll get problems later.

    So, you had it base drained, and didn't make any provision for the water draining out of the base to run into something that would discharge it to the outside of the building?

    Interesting.. I dare say the others are correct - the doorset should be removed, a sill attached with drain holes in the correct place, the brick height shortened (if there is no room at the top to accommodate the increased height due to the sill) and the door reinstalled
