Help a family after housefire

Hi all. My dad needs help. His outbuilding, which included a garage, a sauna and a boiler room, was destroyed by fire more than a month ago and almost burned down the residential building as well, and of course the insurance company takes its time. He has been without water and electricity all this time. My own funds and salary are not enough for all the work to get our childhood home in order again. My father is 81 years old and lives alone. My mother died of cancer 5 years ago.
