Virginia by statute provides a 5 year warranty on the foundation of a new home, Code Section 55-70.1, counting from the earlier of the date of first occupancy or the date of closing. What you describe sure sounds like a foundation issue. I'd suggest contacting the County Department of Building Inspection if you haven't already as in most areas of Virginia, they are fairly active in policing builders to build everything according to Code. Construction litigation can be very expensive, and sometimes the purchase contracts limit some remedies so a close review of the purchase agreement is in order. You may be able to find someone willing to litigate the matter through the State Bar's Lawyer Referral Service, but be aware that construction litigation can be time-consuming, tedious, and expensive, and many attorneys don't like to go down this path.
