Hydrangea and flowering quince

I have just moved into a new property that has been empty for four years so the garden is obviously in a sorry state. I think I have inherited a hydrangea and a flowering quince (see photos and please correct me if I'm wrong) Is there any hope for them? I've just bought some secateurs so hoping I can bring them back from the dead Thank you

 

Well the Quince is still alive. Look below the old flower heads on the Hydrangea and there should, if it is alive, be small brownish buds. You prune back to them.
With the Quince you may be as brutal as you wish.

 

Thanks very much I will check it tomorrow
