    The work was done satisfactorily and helped me in identifying leak and ensured me the water issue is not from sprinklers.

    I had Sherman come out to give me a quote on fixing my ageing / malfunctioning DIY Orbit system. He…read morefound a few things wrong with it (valve stuck in off position, etc) but ultimately we realized it was beyond repair due to its age. He didn't charge me for his time, but did give me a quote to install a professional system as well as expand coverage to the entire back yard. His quote was reasonable / competitive, and I was lucky to get quickly scheduled. He and his crew came out and in a couple days were able to install a brand new Hunter system with sprayers and multiple drip lines. Despite having to trench through my yard, when they were done it looked as good as new. They took special care around existing landscaping and did not damage anything during the installation process. It's been a few months now, and the system is working great. Grass is green and plants are blooming. Sherman is easy to work with and super responsive. I'm extremely happy with the outcome and I'm sure you will be too.

    McKay provided a comprehensive assessment of our whole sprinkler system including the long front…read moredriveway, backyard, and front yard. Within 15 minutes he was able to solve our main issues: a front sprinkler that was blasting the driveway for no reason, and plants dying because the zones were only running one minute, twice a week. He turned off the driveway head, reprogrammed every zone to fifteen minutes four days a week, and flagged a sprinkler head sitting right at the trunk of our acacia that needed moving. He also taught me how to use the system, which I didn't buy or install originally. Really appreciate his help and will contact again for all my system needs and questions. Incredible value for the services rendered.

    Mike and his team were great! Very communicative, friendly, and helpful. We had some broken…read moresprinklers and not only did they quickly fix those, Mike also reduced my 9 zone sprinkler system into 4 zones to make everything more efficient. Would recommend and use again.

    We hired Mike to install irrigation in our backyard. Our previous irrigation system had leaks etc…read more During the site visit, to which Mike showed up drunk (which is fine, whatever), he mentioned that his workers would add irrigation to the pots, remove existing pipes, and bury the low-voltage electric wire which was going to be running along the pipes anyway. Mike canceled on the originally scheduled date once. Finally, Mike sent two guys to install the irrigation. They were fine and were happy to bury the electric wire when requested, but then later Mike came and rudely told me that that wasn't part of the spec, and that "these guys are stupid, if you ask them to wash your dishes they would do that too". I didn't appreciate the racist comment but let it go. But that was not all... there isn't much space between our home and the next one (think 12 inches or so), and he asked how we would get the siding repaired should we ever need to. I said I didn't know.. he said "maybe you can hire an Ethiopian to get in there, they're all thin because of the famine there". Truly WTF Anyway... judging the work itself - the installation seemed fine when it was done, but we later noticed and had to patch four leaks. I'm not sure if there are more. The piping they used, I was later told, was lower quality too. I'm not sure how long it'll last. I was unable to get competing quotes because we were short on time, but later I realized that his quote was a bit higher than others for the same work. He insisted I pay in cash, and so I did. I then spent literal WEEKS following up with him for an invoice (which I need for bookkeeping), and he kept blowing me off. He said things like "I had a family emergency", "I have 50 jobs this week", "I'm busy" and then simply stopped responding. He also said that it's just 2 minutes of work and that he would get to it... but he never did.
