Recommended Customer Reviews

Fabulous company! I was referred to them from NextDoor and from my first call I knew they were good.
I called and left a voicemail. Robert returned my call within 24 hrs. I explained what my issue was and he assured me they could help. He explained that they were pretty booked but that he could squeeze me in next Tuesday. The next day I received an email that they had a cancelation for today (Saturday) so I grabbed it. I then promptly received an email confirming my appt and what their fees were.
Today, they showed up and I explained my issue. Well, I'm embarrassed to say, it was user error. However, since I was being charged for an hour of time, they went throughout my property, ran various tests on my sprinkler system, checked everything including valves etc and gave a clean bill of health. What they ended up doing today was their bi-annual service that they offer. I will be having them back in fall/winter to do another service check.
I highly recommend Peninsula Irrigation.

I did not work with them because I felt their fees were prohibitive for the size of my project. However, they were not unique in that respect. All the irrigation companies were in the same ballpark as what they wanted to charge. We are currently facing the highest rate of inflation in 40 years which is going to be followed by a deep and long recession. However, despite this reality, they all want to charge $75-$100 per hour for labor rates. I am not willing to pay those rates to dig a ditch and glue the plastic pipe together.

I cannot say enough good things about these guys. They returned my call promptly, made an appointment, sent a reminder, showed up on time, were courteous and professional, fixed the leak in the pipe in my front yard quickly, and assessed and fixed the other issues with my sprinkler system in the backyard. I was so impressed, I plan on having them come out to put in an entire new sprinkler system for both my front and backyard. Could not be happier with their service.

I can't recommend this company enough. Rob, the owner, is a man of his word, this is the most important thing in this review. We hired Peninsula Irrigation recently for a sprinkler upgrade. His crews were professional and courteous. With all jobs, there are things that are missed or don't get done properly the first go around. With our job Rob personally made sure that everything was taken care of. He did not cut corners and truly put the client first. Our garden has never looked more healthy, if you are looking for an honest company with great values to match their great skills, then you need to call these guys.

These guys are good at fixing problems but they charge a lot ( more than a high-priced lawyer or doctor for a sprinkler technician!!). And they often send two guys so you pay twice as much for someone who spends most the time watching the lead guy and fetching and carrying. They act like it is a minor job until you see the bill and the hours that they racked up and the owner refuses to reduce the amount. They tell me that the technicians don't get a commission but I doubt that.
So I recommend that people only use them in emergencies- in that situation, you don't mind paying the high prices. But avoid them for adjustment and installation ( $ 1000s for laying drip irrigation in a small yard!).
And to add insult to injury, the 12-month warranty has a lot of caveats that you only discover after they return and do work that should have been covered by the so-called warranty.

This is the second time Peninsula Irrigation has come to our rescue. This time it was to install a new controller and replace/trouble-shoot many renegade sprinkler heads. Great communication, quality work, friendly crew (Junior), and totally reasonable pricing. Highly recommend!

Quick and knowledgeable on fixing an issue I had with my sprinklers. Great job Joe and Dominic!

I have done my own irrigation work previously but just don't have the time anymore. It's hard to find a company to do this right at a fair price but we did. Peninsula Irrigation is excellent! The work was tidy and top notch, and the final invoice was so detailed that I could actually see what the charges were for. This is such a rarity nowadays and is so greatly appreciated. It took several weeks between the first and second visit to get the job completed but it's not their fault they are busy! I would not hesitate to recommend Peninsula Irrigation for your irrigation needs. They did a complete repair and overhaul of the drip system we inherited when we bought our house, including fixing broken pipes and adding onto the system. We discussed creative solutions for our planter beds and our lead tech, Junior, took time to explain our options. We could not be more pleased with the quantify of the work and transparency of the process. Thank you!

We've done business with Peninsula Irrigation for at least a decade, generally on a yearly basis. We're always impressed by the quality of service & the fairness of charges, as well as the competence & courtesy or their technicians. They can be a bit slow to respond in high traffic seasons like early spring, but worth the wait.

Peninsula Irrigation is the type of service provider I wish all vendors were -- responsive, reasonable, professional -- a community-minded business that wants to build a long term relationship.
Recently, on an early Saturday morning, I learned my PVC garden pipe had burst overnight. I cringed to find a ""geyser"" and baby swimming pool in my backyard.
Thankfully, handy neighbors provided a temporary fix.
I then began contacting a myriad of plumbers. Guy Plumbing did not provide the services I needed, however, they provided a number of referrals. Peninsula Irrigation was one of them.
From the outset, the company was responsive. Robert Porterfield contacted me via email asking to speak to obtain additional information. He then called at the scheduled time -- a rarity.
Robert was unbelievably friendly and very helpful.
He re-prioritized his service worker's schedule to meet my urgent need. Learning I had lost my position due to COVID 19, he offered a flexible payment plan. I was stunned. In this time of angst, here was an act of random kindness.
Every interaction with Peninsula Irrigation was remarkable!
From the email I received when the technician was fifteen minutes out and the technician's early arrival, to his patient education of what he was doing to resolve the issue and his clean-up of the area where he had worked.
Kudos to Peninsula Irrigation and their team. An old-fashioned business that believes in and delivers customer service of the highest quality. I will be a lifelong customer.
