Richmond American Homes Keys to the American Dream along with a $14k repair bill for poor work Denver Colorado

Richmond did not do a good job with grading my home and accounting for the ground water underneath my home and the sump pump issues from neighbors home and mine.  I am stuck with a $14k bill because of their poor work.  It is attached. My issues has gone all the way up to the Mayor's Office and I am now hiring an attorney for a class action lawsuit. Their Warranty services came and took pictures over a year ago and yet, did nothing.

What company in good conscious builds a half-*** new home for consumers and leave them with a $14K repair bill afterwards?  How do these people sleep?  That is my question.
