If you need irrigation work CIS should be the first and only call you make. CIS and crew were great to deal with (props to David specifically for being knowledgable, professional and friendly.) I'd give 10 stars if I could.
We bought a new-to-us home in Gilbert that had an existing irrigation system installed who-knows-when. We had some stem wall repair work done and fiber internet run to the house, both of which required trenching. Neither were very careful and made Swiss cheese of the existing system. Initially I just asked to repair a known spot that was leaking and was warned it was likely not a resolution to the issue but they'd handle it anyways if that is what I wanted. I asked for the simple repairs and of course it didn't work. They came back out and did a second round at my request after we discovered more leaks and dug a little deeper into the system. That still didn't work so I had them complete a full replacement (an expense I was hoping to avoid but it is what it is.) They never over or double charged me for anything, and they did a great job replacing everything that needed to be replaced. They gave me plenty of drips and, more importantly, plenty of places to open the main line to flush when I inevitably need to install a goof plug or otherwise perform a future repair. On this experience alone I would recommend them.
A couple of weeks later I had one zone that was not shutting off after the timer ended. I suspected either the new manifold (bad solenoid or debris in the valve) or the new controller. New, bad parts seem to common these days for everything. David came back out again and found a small pebble had gotten itself into the valve, stopping it from closing. He was in and out quickly, flushing the manifold and cleaning the valve blockage. At my request, showed me how to take apart the valve if it happens again. This is above and beyond.
