Is there anything I can do about damage made by tradesmen?

I have a feeling I'm just going to have to put up with this one but it feels wrong.

Just finished having new doors and windows fitted throughout the house and now the work is finished, I've noticed quite a lot of damage that is obviously due to tools or materials dropped, it's mostly large dents and scratches in the radiators under the windows and a large chip out of the bathroom sink.
We have already complained as they disconnected one of the bedroom radiator pipes and it's leaked through the floor/ceiling and someone is coming out to look at it today.

I'm just not sure I can prove the dents etc weren't there before??

You should definatley contact them and ask them to rectofy or pay for damage. I work for a heating company and would expect to be contra-charged if our workers did any damage (our insurance woudl cover us for anything major).
