Helping my grandfather rebuild his home

On October 14 around 4 am my grandfather, Pablo went through a traumatic experience due to his house being caught on fire. My grandpa lost his home, he lost everything in his home including valuables and the precious memories he made during his years in his home. The fire broke out and my grandfather was fortunate enough to escape out of a window. Out of desperation he tried to put out the fire and he burned his feet. Due to the circumstances my grandpa set up a tent for shelter. His neighbors are contributing to him by giving him food through this disastrous incident he has to experience. My grandfather has done a lot for our family and has sacrificed so much for me, my brother, and my mother. He is funny, loving and caring. So I want to do my absolute best to help him out. Please anything  would help. Thank you.
