One customer says Calvin audited their system and identified a couple of areas that needed upgrades, and another says he provided custom irrigation design for raised beds. A customer says GreenStandard installed their irrigation system and has handled maintenance since, and another says Calvin updated an old sprinkler system in 2025 that had not run for years, over four full days of work. In a 2025 review, a customer said Calvin repaired every malfunctioning sprinkler head, adjusted the spray on others and returned the next day to check. Another 2025 customer said he fixed their irrigation's backflow and a pipe leak, and in a 2025 review a customer said he located a wiring break the afternoon they called.

Calvin, the owner, personally took care of my irrigation repair. Booking the appointment was easy and fast. Calvin showed up on time, investigated the issue, and carefully explained what the issue was, and even performed a quick test to verify. With-in an hour the repair was complete and the price was much less than I expected. Calvin is professional, patient, and extremely kind. I will use his firm from now own. Don't hesitate to give him a call!
Calvin and his team did a great job getting our sprinkler system in order. All heads are now positioned to water the lawn, they’re all rotating as they should be, and we’re very happy with their work. I highly recommend Green Standard.
Calvin and his crew were fantastic! Highly recommend!
Calvin was great. My last company dropped the back, he came and audited my system and was able to identify a couple of areas that needed upgrades. I will def be using him moving forward for any irrigation needs!
Extremely professional and knowledgeable. Has responded to calls and any issues that have arisen promptly. I highly recommend
