M.A.G. Irrigation is an East Freetown outfit that's been putting in and servicing underground lawn sprinkler systems across southeastern Massachusetts (and into Rhode Island, per BBB) for decades — the company's own site says 35 years, while Better Business Bureau records trace the corporation back to 1988–1990. It's run by George Carvalho as president and Maggie Carvalho as treasurer, names that turn up again and again in its reviews. The volume here is real: 4.8 stars across 65 Google reviews and 4.9 across 123 tracked by Porch, with the same names — George, Rick, Maggie, Nicole — recurring across years of write-ups. Reviewers keep coming back to the same things: accurate walkthrough quotes, crews that leave the lawn close to how they found it, and an office that calls back. In its most recent review, a customer described George surveying the yard and talking them out of a booster pump that other installers had insisted on — and said it worked fine without one. Longtime customers describe sticking with the company for a decade or more; one reviewer, writing in 2024, said they'd used MAG at a previous house more than 20 years earlier with no issues. Not every account is glowing. In a 2022 review, one customer called it "always trying to sell services not needed." A more detailed 2022 complaint, from someone who'd used the company for nearly 10 years, described paying about $400 for a wifi Hunter controller upgrade, being told the sprinkler heads were fine when they asked for a check, then finding burned patches of lawn and leaking, damaged heads two weeks later. For a routine install or seasonal service, the recent record is strong; if you're adding equipment or a system upgrade, it's worth asking them to walk you through exactly what gets inspected and confirmed before they leave.
I would highly recommend MAG Irrigation after my experience. Maggie and Nicole in the office e were very pleasant to deal with and were always keeping me apprised as to the progress of the installation. George came out and surveyed the yard and gave us a proposal. He suggested we NOT get a booster pump as it was u Cesar’s even though several other installers said I had to have one. After the installment, it worked great and he was right. George’s brother and a crew member stayed behind to walk me through the system and answered all my questions. Myself and my lawn thank MAG Irrigation and their team, so nice to work with a local family run business who do what they say they are going to do!
Very good experience!
What an excellent team. So impressed with the awesome communication from the office staff to prepare me for what to expect on installation day. Installation crew were polite and professional. Very happy with their work, all done with great care and minimal disturbance to my lawn. When installation completed loved the one on one attention from George the owner on how to run the system. Great job thank you so much.
Couldn't be happier with every aspect of the service we received from M.A.G. Irrigation. It was a simle process of filling out a request for a quote online. Heard back from Maggie the same day and was able to schedule an appointment within the week. They worked very closely with our landscaper who was putting in new sod and were able to coordiate perfect timing to complete the job at a very busy time of year for them. The crew and George, the owner were great. Showed up on time and I have never seen a group start working as fast as they did. Fantastic!
We had our entire system repaired and adjusted, Rick and the crew were professional and just did a fantastic job ! Highly recommend
