My BIL's house burnt down!

I feel so bad for them, they are only married a year and a half, and just moved in last May! They put their hearts and souls into this house, and it went up in flames yesterday, due to an electrical fire. My BIL is injured so is home and his home was his baby. He went out for 1 1/2 and came home to this. Worst of all, their 2 dogs were out on the deck (which is where it started), and were apparently trying to get back in the house, and both died Hardly anything is salvageable, but I heard their wedding album was okay. We spent the last couple of holidays there, because they wanted the whole family to share their new home, they were so generous and gracious when we there. Everything was brand new, all their stuff from their wedding, new furniture throughout, a new deck, outdoor jacuzzi. It's all gone, and they are homeless.

I have no idea what to do for them. DH was with them last night, and we are going there (Westchester) tomorrow. But, with something like this I'm not sure what I can do to help.....
