Imagine waking up Sunday and seeing a mini water fountain continuously spray water all over your…read morefence and concrete, and hitting the neighbor's yard too. The sprinkler control panel did bot shut down the faulty sprinkler, so its likely a mechanical issue with the control valves in the backyard that failed open. I have no idea how to DIY this so I was lucky to find Ostwald. Yep, they are a 24/7 company and were able to comr out same day in a few hours. Darvin and his helper replaced my entire sprinkler control valve system, faulty sprinkler heads, and did some excavation to fix some leaky pipes. About 3 hours total - not a straightforward job since it also involved wiring and some backyard plumbing. I have an older house so they actually had to shutoff water to the house for a few hours. Not sure why the sprinkler system does not have a separate isolation valve. Maybe it does but its not obvious. Definitely recommend Ostwald Sprinkler Repair for quick turnarounds and responsive service, even on Sundays when most other sprinkler repair companies are closed.

Oswald was very efficient in getting back to us for a irrigation pipe repair for our front yard…read more Time between contacting him and getting him to come out to give us a quote was less than 24 hours, and the actual repair happened 3 days later. We were very pleased with the turn around as well as the price that we were quoted. His communication throughout the process was great and we felt like we were in good hands. We would be happy to work with him again for any irrigation work for our home.

McKay Irrigation Systems gets a very high rating on Yelp (and also from some of my neighbors) for a…read morereason: they do great work. Sherman McKay runs the show, and he runs it well. He's great with communication, and his estimate was right on point. I had some drainage work done at my house which trashed my entire irrigation system, so I needed to have it replaced, both in the front and back yard. The McKay crew did a bang up job of it. They came in on time and on budget. They had the whole system laid out and running within about two days. Then Sherman spent some time with me to make sure I knew how to operate the controllers. In fact, they do more than irrigation, and I will likely have them come back and put in some new plants and do some other work in my backyard. They did such a good job with the irrigation system that I have high confidence they will make quick work of the other jobs too. I strongly recommend them.

His crew was exceptional. They were courteous, punctual and experienced. They included my husband and me in decision making regarding placement of paths, flagstone and plants, which we greatly appreciated. It is rare to find such exemplary customer service these days and both Jose and his entire crew were amazing. I would definitely recommend his service to friends and family.

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.

We started getting alerts from EBMUD about a possible leak at our house, which immediately had us…read moreon edge. We had two different plumbers come out, but neither could figure out where the issue was coming from. EBMUD gave us access to monitor our water usage online, and once we started tracking it, the numbers seemed to be getting worse... definitely not what you want to see. At that point, both plumbers recommended bringing in a leak detection specialist. We were pretty stressed, thinking this could turn into a major (and expensive) problem, so we started calling around trying to find someone reputable who could come out quickly. Steve from Water Shield Leak Detection was able to come out that same afternoon, which was a huge relief. He was thorough, ran multiple tests, and took the time to explain everything in a way that actually made sense. More importantly, he was confident that we weren't dealing with a major issue like we originally feared. He gave us a few things to monitor and try on our end, and even offered to come back and do additional testing to confirm everything at no extra charge. That kind of follow-through is rare. We were incredibly grateful he could come out on such short notice and, honestly, just put our minds at ease. Highly recommend if you're dealing with anything similar.

We decided to get a second opinion and found a plumber who found the leak from just hearing a hissing from the toilet and replaced a part for a few hundred bucks. Had we had gone with Water Shield, not only would we have wasted $7k, they wouldn't have even fixed the leak. We still had to waste $400 for their initial inspection , but lesson learned, always get several quotes.

We set the construction date for February 19th which lasted until February 25th. Jesus, the foreman, was great at communicating the steps required for the build. He would often check in to make sure that we got the end product we desired and was receptive to feedback for the design. With their workmanship guarantee, we have nothing to worry about. Overall, the process was smooth and hassle free. We would be happy to recommend them to others for their landscaping needs.
