I am very happy with the service Riverstone provided for my property. I seen them here on homestars along with a couple other companys. After calling a few and getting them to come for a quote, I found Riverstone to be the most professional and knowledgable about the job, they explained to me exactly what they would be doing and where they would be placing all the sprinklers. They had done my sprinklers in june 2014 and came by in October to flush the system out for the winter, and have already called me to book an appointment to re-open them for the summer. Over all I am very happy with the service they provided and would definetly reccomend this company to anybody looking for new sprinkler installations, just give them a call and you will see what I am talking about.
