Recently moved house and a couple of the windows don’t sit flush with the frame giving off a light draft. The attached photos show one of the worst and it looks like some new sealing might go a long way but can this be done DIY by making some adjustments ? I’m not quite sure what needs adjusting I’ve made a few tweaks, tightened all screws etc but it hasn’t completely fixed it.

They obviously closed properly at some point so it shouldn’t be too difficult to have them doing it again?

I’ve applied WD40 to all joints.
