Render over block skin to timber frame house - finishing under windows

[Haku]

Am I correct to assume there should be a stop bead set 20mm down from the soffit and 5/15mm down from the underside of window cills for the render? I asked the builders to leave this gap in the blockwork and then fill with compriband, they've then just rendered over the top of the compriband. I assume I need to ask them to correct this and leave a gap for settlement. Do you just fill the gap with flexible mastic over the top of the compriband or leave it open? (On the clad areas they've left the gap at soffit & under cill level but I gave them a detailed instruction on how to install the cladding)

It’s not normal to ask for this 

But if you asked They should have done it

Have you paid them? perhaps hold off until you're happy they've done a good job.
