I would recommend John and his crew to anyone, he was not the cheapest quote I got but very competitive
He was on time, made excellent suggestions and and his crew where very professional.
This has been my second summer since my initial instillation and the system has worked flawlessly and my lawn and flower beds have never looked better.
John is always willing to drop by to make adjustments but also took the time to show me how to do it myself if I chose to do so, being quite handy I find that very useful.
If you are considering getting an irrigation system you, Green Valley is someone to seriously consider.
