Dominion Homes Pulte Homes Refused to repair/replace my driveway, porch and walkway due to spalling Louisville Kentucky

Dominon Homes built my home in Creekview Estates in December of 2012.  By spring of 2013 our driveway had chipped away over 100% of the driveway, the walkway and steps also.  The front step had a huge crack across the front, which they 'fixed' and it had reappeared within 2 months.  Dominion, thru Brad Morgan, totally denied any responsibility for the issue.  They also told us that it was due to salt used on the roadway over the winter dripping off our cars.  That really makes sense, especially with it being on the sidewalk and porch.  If that was the case, shouldn't all the driveways in our subdivision look the same?  There are a few, but not all.    Dominion Homes does nothing but deny any issues a homeowner has.  Even if they agree to do something about a problem - it is never carried out.  There is no way a driveway, not even a year old, should have these issues.  They should be made to stand behind their 'warranties' and their contractors.  I would never build a house through them again, and I tell anyone I know not too.
