What is the cost for a 4 inch cement patio in Northern Virginia/ DC area?

Question

I have been researching cost for this and they seem to vary a lot. Any advise from the pros out there? And this will be next to my 1950s home and over a basement wall ... I was hoping this would keep the basement dryer since the house is on a slight hill and I thought the cement would help the water run off better and I could use a patio.

Answer 1

You shpuldn't pay more htan $7 per sq/ft. if you use just concret.
