I have had John out here twice, and he did a great job both times. Both jobs were a bit of a challenge, but he still kept the cost in the excellent range. I will call him again.

John made my service a rewarding, efficient and educational experience. He was here on time and found the problem with my system and fixed it all within an hour and for a reasonable price. If there's something down the road that I can't handle, I'm not going to hesitate in calling him again.

Great knowledge and professionalism. Same day service was appreciated because I had a leak and was wasting water.

The owner came out on a Sunday to repair a major leak that was flooding the front of my house and which couldn't be shut off without turning off the main water main. He spent over 4 hrs repairing the 3 leaks he found. Thus entailed him having to dig a 3 foot hole in the mud caused by the leak. He even came back the next day to finish some issues found with the sprinkler valves.

The owner is a hard worker and I didn't find his price exorbitant for it being a Sunday and the work involved. I would definitely use him again when I redo my whole sprinkler system. He should do well for himself as a new business owner hungry for customers.

John is a very nice guy and repaired a valve for us on short notice. Great job. Will be using them again if the need arises.

I had John out to do a pretty big job. He adding a water line, added a valve, reconfigured existing heads and placed new sod in a complex pattern. It took him a couple of long days but he and his guys did a great job. There is still more to be done in the back yard, so I'll be having John back in the spring!

John of OC Sprinkler Service did an amazing job for my yard. I've had multiple companies do landscaping jobs & each one has caused damage to my sprinkler heads & pipes. Other companies quoted me that I needed to completely replace the whole system and start from scratch. John & his co-worker fixed everything in one day! They replaced 20+ sprinkler heads & repaired multiple broken pipes all at a fraction of the price that other companies had quoted me. John was very professional, extremely efficient, on-time & even did more work than the job he quoted & did not even charge for the extra work. After all the bad experiences that I recently had with sprinkler repair companies & ""landscape"" companies it's a breath of fresh air to have found John & OC Sprinkler Service. I would recommend him to everyone & definitely will use them in the future for sprinkler/irrigation & landscaping needs.

Thank you OC sprinkler ( John ). We had an emergency leak. So I called John yesterday to ask him when he could come and fix and he said he can do it at 6:30 in the morning today. What a great service. Thanks Oc sprinklers you are awesome!!!

First of all let me say that John is very courteous. It was nice that when I meet him, he shook my hand and looked me in the eye. John also showed up 10 minutes earlier than his schedule time to be there so that was refreshing.

I told John that that my sprinklers in my front yard were flooding the yard and that I thought that the solenoid might be stuck open at the end of the cycle. I also have a ton of over-spray and asked John what i needed. He first took a look at my control box and told me that this box was ""Overly complicated, but simple to understand"". He spent 20 minutes reprogramming the box. He told me that the box had preciously been set for the front sprinklers to go for 3 hours! wow! I then asked him what else he thought I needed and he told me i need there tune up and that would be $149.00. I asked him how much for programming the panel and he said that would be $79.99....I thought that was a lot for 20 minute reprogram, however, I decided to do the tune up and John included the re-programming in for free. So I gave him $175 because I wanted to support a young man running his own business.

Then came the first night, all 6 stations ran continuous, back to back for 4 hours and flooded everywhere. I turned the water off and called John later in the day. He said he would meet me the next day. The next day out of nowhere he text me and says his partner came to my house, unannounced and without setting appointment and reprogrammed the panel without me there. He also states that this guy has 25 years in the business and everything should be fine....

Next time the sprinklers came on, all the cycles went great until the last station, the front sprinklers again ran for over an hour and flooded the front again!

I went ahead and texted John the problem and he wrote...""the diaphragm of the valve must be sticking open (even though he told me prior the box was set to run for 3 hours), we charge $89.00 for that but will take off $20 for the inconvenience""....no thanks

I will have to go elsewhere for sprinkler service to get this fixed now.
