I had a new home built less then a year ago HELP can I do anything? - home built trailler ontario

Since March, it was the house built, as I sewer pipes, dishwashers, burst that flooded my kitchen, and hurled stones, the coating should be connected, and I have a bad odor from my crawl space. They had to replace my pump sewage grinder. I continue with the things that are wrong. What can I do who have come and fix it, but it is not right.
