Sash wedge issue

[omph]

I installed a sash wedge on the top of the casement frame for side hung window to pull the sash in (it's out by approx 4mm). It's pulled it in approx 2mm but there is still a gap. How do I bring it some more ? do I need a bigger wedge ? or maybe a sash riser ?

On top of a casement that is side hung?

What is it you've fitted, is it a closing wedge or a run up block?

Sorry, not the top - ignore that. Its a closing wedge installed on the upper part of the side.

Could be a worn hinge not pulling in enough?

I replaced them. Its been like this from the day the window was installed
