You said you lifted paving to do the lawn, so I'd guess the ground underneath may not have been great unless you forked in some new soil and compost. It would also have been compacted. You can help that by aerating , as you've said, and if you sweep some fine grit or coarse sand into the holes as well, that will keep the structure more open and help prevent it getting compacted in future. If it's a bit shady, it might be better using a seed mix specifically for those conditions, and you could add some compost or topsoil first and rake it level before sowing. A spring feed will help, and it might be worth trying that first, as it may just be that the grass needs a little boost. Most lawns look a bit tired and jaded at this time of year. A bit like gardeners!
