I think you've already done everything necessary, shutting off the water is the most important task. Well, until the comes, you can clean and see what caused the burst pipe, maybe the pipes are already old or something else. My brother once had a burst pipe, but he did not spend a penny on repairs, because it was related to other pipes that were laid before he lived there, in general, it was not his fault. So he was reimbursed for the money he spent on the repairs.
