Recommended Customer Reviews
Peninsula performed exceptional work for my defunct and outdated sprinkler system. The previous contractor I hired for the job was a real amateur and made a mess of everything including leaks and exploding pipes. I knew it was time to call in real professionals to complete the job and fix the mess. Josh and his small army rolled in at dawn and got the job done with high quality results. Josh was very knowledgeable and friendly (even though I sprayed him with the hose) in all phases as was his crew. Highly recommend, especially if it is a difficult task!
Steven T.We bought a house a few months ago and Peninsula came out and did a full system test. They quickly identified 2 major leaks and made the necessary adjustments to the system. The owner Nathan is responsive and his technicians are courteous.
Very expensive and less than effective. Technician adjusted/replaced a few sprinkler heads and told us that our water pressure was too low to service the irrigation layout. He recommended replacing the line between the meter box and the house for $2,200. The technician from the company we contacted for a second bid adjusted the pressure with a few turns of a valve. Simple...10 minutes...fixed. Very glad we didn't proceed with Pen Irrigation's recommendation and therefore can't recommend them.
During the four years we've used Peninsula Irrigation, we've been very happy. They are quick to call back and appointments are always timely. Josh and others have diagnosed problems with our system and conducted repairs fast. A+
Fantastic service and experience- they replied quickly to my initial voicemail, sent a reminder email the day before my appointment, and the tech (Josh, who was great) called when he was on his way. All in all, it took about 45 minutes for our issue to be diagnosed and fixed, with clear explanations of what was happening and why. Josh also explained other, non-critical, issues with our sprinklers, what it would cost to fix them, and then left me to make a decision about it without any pressure or salesmanship.
I'll definitely call them again.
My sprinklers were leaking and Robert showed up in 15 minutes. He diagnosed and resolved it immediately. He will be back to fix the old valves causing the problem next week. The fact that Robert showed up to stop the leak was very much appreciated. I highly recommend Peninsula Irrigation and Robert. He is very knowledgeable and friendly. Any future work on sprinklers is definitely going to Peninsula Irrigation.
Very pricey. I found someone else to come out and repair my sprinkler problems, parts and labor included, for less than what Peninsula Irrigation wanted to charge just to come out and look for 30 minutes. Unless you have a complex job, I would keep looking.
They installed a new smart controller for my irrigation system (Rachio Iro). Robert showed up, installed, and walked me through the setup personally. It was very efficient, without any padding or wasted time. It's working great, so the effort was much appreciated. Recommended.
Carlos did an amazing job fixing my complicated irrigation problems. He is very knowledgeable and friendly. He also thinks outside of the box to fix my sprinkler issues. I would recommend him to anyone who has sprinkler issues!
We had a great experience with Peninsula Irrigation this week. We had a leak in the yard, and a neighbor recommended that their gardener could fix it while also doing some yard work for us. The (very nice) gardener did try to fix it, but ended up only making it worse -- now four leaks! Josh and Joe from Peninsula Irrigation came out and diagnosed that the problem was at the main valve, not with the pipes in the grass. Not only did they efficiently fix the problem and explain the mechanics of the problem to me, but they were AMAZINGLY nice to my 3 1/2 year old son.
The valves are in the flower box right outside a window, and my son spent the entire time standing in the window talking to them. Josh explained to my son what he was doing, gave him ""important jobs"" (e.g., to remember the color of a wire), and answered my son's (sometimes tedious) questions. Thank you!
