Pipes exploded in the middle of our current Reno

So we are in the middle of a reno on a 3-1 ranch. The house if heated with boiler system( That we just replaced 1 month ago) and baseboard hot water heat. We had the temp set on 65 and didnt have anyone over there working during the holiday ( 23rd-26th). My painter just went over and found the whole house saturated and pouring water from a couple places in the baseboard pipes and basically the whole house was underwater for days and we lost alot of supplies and our brand new cabinets are destroyed, along with prob the hot water tank, new boiler, washer and dryer and whatever else I havent found yet. . I already filed a claim with my insurance. Any tips???
