I’ve worked with quite a few irrigation companies and Professional Irrigation is by far my fav go-to for bids and installation. They are always responsive and quick with questions and requests for bids, and they have a very responsive scheduling department. They are always there to remind me when the time has come to address my annual St Louis County required backflip prevention, and even have discounted annual plans to choose from.

Professional Irrigation's technician was very thorough and patient as I took notes about where my sprinkler heads are, etc. as I'm new to my sprinkler system. He also repaired my rain gauge which had not been working. The office staff was also friendly and helpful about setting up the appointment and requesting a call when technician was on the way.
