Called Chris last year for relaying of reticulation pipes and changing bore pump; first he surprised me by telling that he remembered what work he had done about 9 years ago for previous owner at that property, and then he surprised me by coming back to the property to check the work he had done for me [after I had already paid him and I was already happy with the work]. He doesn't think work is complete until he is satisfied too.
Called Chris yesterday for replacement of controller and relaying of retic on another property and servicing of sprinklers on another one; as always, work completed to my satisfaction.
