I live in development of 75 houses that we all built about 9-11 years ago. A few of the houses (close friends) have had leaks in their master bathrooms that required extensive repair. Of course, I also have a leak and am wondering if we have grounds for a lawsuit against the builder, since so many of us have had the same problem. Anyone ever been involved in this type of suit and any advice as to how we should begin to pursue this?
