My builder was late at completing my rough grade (fall 2013), so by the time I got the chance to look into final grading companies, I decided to go contact River Valley Final Grading because they responded to my inquiries quickly, even though it was the end of their season (Nov 2013). They had me at the top of their list for the following spring. Their crew of 6 that arrived was professional, tidy, quiet, and hard working. They cleaned up the road and driveway very well once they were done. Their surveyors were there the same day and they had the City notified quickly (I didn't have to worry about a thing). The City was even quick, inspecting 2 days after the crew did the final grade. Of course it passed.
I have a large pie lot, and I can't imagine taking on a job like that myself, or with friends, especially if a yard isn't bobcat accessible as mine is.
I also like that River Valley is a modern company, in that all signing is done electronically, and they accept email payment transfer. There was no paper to deal with. Their staff was quick to respond to emails, and didn't hesitate to provide advise and recommendations on other services.
