I know its way early for this thread, but I'm always trying to open new niches in the marketplace.
I've been installing and repairing systems for 3 years now. I have had several people ask me about winterization, and I think I can add it as easy irrigation work to my contracted maintenance accounts, and as a selling feature on new installs. If I'm in charge of the start up and shut down, I can be sure that everything is functioning and I could set all timers correctly to abide by water regulations and to water for the correct amount of time.
I was wondering what your technique is for others in zone 7. What all do you include in the service?
