For more than 30 years, Bill Ritchie Construction has been providing Columbia, Dutchess and Greene counties with high quality concrete construction both residential and commercial. We pour concrete walls for new construction, additions and retaining walls. We also perform flatwork such as floors for garages and basements as well as slabs and sidewalks.We have recently added all new 9’4” forms to our equipment inventory which gives more than a foot of added headroom for finished basements.
