Great service, it's just too bad he's so busy. He was helpful and had reasonable fees when he came.

After receiving a few quotes from different companies on yelp I decided to go with OC Irrigation. John helped me redo my front and back yard. We added about 10 sprinkler heads and a new control panel to my system and my grass is looking better than ever. I have already referred the to to my family. Thank you!

John was great to work with! Came in for an inspection and got right down to business. He quickly identified multiple issues with our current irrigation system, and identified solutions to correct them. When he came out to do the work, he was efficient and did the job well - no cut corners here! Others have mentioned his lack of communication, but I didn't have any issues. He's clearly a busy guy, which he should be because he does great work. Thanks John!

John doesn't not return phone calls. Been calling and left messages for two weeks. Still haven't heard back.

John is a very professional and thorough businessman. We appreciated his work last year 2017 and appreciated his work today 2018. So wonderfully refreshing to find a company and man who answers phone calls very quickly and comes out to our home ready to work, completes the job and charges accordingly. Thank you, John!!

John replied quickly to our inquiry to setup an appointment for a free assessment. He came by a day or so later and gave a thorough evaluation of our front sprinklers. He found the issues with our poor flow and coverage and provided a good estimate within our stated budget. He and his coworker came back a week later and changed out a valve, located and replaced a broken/leaking head, moved one head 2' for wider coverage, and tuned all the heads. Our front sprinklers work great now with excellent coverage with half the watering time we were used to. There's essentially no evidence of the holes they dug! Excellent service we're happy to recommend and revisit if needed. Thanks John!

Decided to redo my flower beds and then part way thru it dawned on me that we should really redo the sprinkler system as it was from the 80's. It never worked that well and really relied on the rain to supplement, alas the rain does not come. Found this company on Yelp and read the history on the website and all the reviews and decided this was the one. Have not been disappointed. John and his crew are very professional and do all that is needed and more. They changed some of the sprayheads and nozzles, installed new valves, created a new pattern of sprayheads in the front yard, moved a couple to new locations and capped an unneeded one off. They then fine -tuned each nozzle.
Am looking to forward to a much better watered garden and lawn with no water in unwanted places. Margaret E Morrissey

I contacted Orange County Irrigation Service for some repair and modification at my mother's house. The timer was not working, there were a couple underground leaks and poor coverage in some areas. John came out right away and spotted the problem with the wiring to the valves and corrected that problem on the spot. At my request he provided two estimates. One for the basic leak repair with tune up and another for more work to move and add sprinklers for improved coverage. We chose the later. John scheduled to come out this crew and complete the work. I am very pleased with the outcome. A few weeks after on the the sprinkler heads just started leaking like a geyser. John came out right away and replaced the defective sprinkler under warranty. I greatly appreciate his attention to detail.

The best sprinkler installation and repair company in Orange County! John came to my house 2 years ago because I was tired of watering my backyard by hand and they installed an amazing sprinkler system at a very good rate! I recently called him back because I needed to move two of the sprinkler heads to another location due to a new bbq area I'm installing, he came out on a Saturday and moved both sprinkler heads and adjusted them to perfection! I'm very satisfied with the quality of service he provides!!

John and his crew are awesome. From start to finish, my wife and I were impressed with John's attention to detail, great communication and quality of work. His estimate for a total rework of our system was thorough and fair. He and his team showed up bright and early each day and finished our project in great time. Our new sprinkler system is more extensive than before and it better services and waters the lawn, flower beds and raised garden plots. The drip lines have saved our lives and are already giving our veggies more water than we were getting them. Overall, a great experience and an outstanding service/product. I highly recommend hiring John and his team!
