Best Water Heater Installation in San Francisco CA

Mario was absolutely great! He showed up within 30 mins of contacting the Works plumbing office, detected the issue with the hot water pipe leak within mins and fixed the issue in an hour. Yeah and these guys were very reasonably priced.. I now have the hot water back in the house and am estatic.. what more can one ask from a plumbing service :)

Travis and Ray came out today and were professional, courteous, friendly, knowledgeable, and took the time to explain how and why the repairs were needed.

They are cheap and did the job. Replaced angle stops and fixed my toilet seat of an old Kohler toilet design that are no longer in use.
I showed a video of how it was done and the person did it instantly.

This is my first time ever leaving a review. I am so thankful for One Sources help at 4:30 am I had to share it. I woke to water coming from the kitchen upstairs through the lights in my downstairs bathroom. A pipe malfunctioned on the dishwasher and was flowing onto the kitchen floor and then flooding the kitchen. I frantically called 4 plumbers who said 24hr service but it turns out they just have an answering service and I was told someone would get back to me. No one did. The 5th company was One Source and he talked me through how to shut off the water which turns out to be pretty easy if you know where to look. I wasn't charged anything and it was just a very nice decent thing to do for someone at that ungodly hour in the morning. Thank you, Thank you!!

Extremely professional, underpromised and over delivered. Definitely gained a life long client.

Excellent plumber and reasonable rates! Responds quickly to calls.

This company was professional from begin to finish. My ac went out and they arrived the same day to give me estimates on a new system. The price was reasonable and fair. Two days later they arrived out to install. The guys were respectful, clean, and explained thoroughly. I couldn't be happier. I endorse them.

I used O'Grady service in 5-2020. Water Dept notified me water leakage. AWR(American Water Resources) referred me to O'Grady. They came immediately and detected leakage in 2 toilets due to faulty flappers. They got parts next day and fixed them. Up to this day both toilets in good shape.
Thank you to O'Grady's excellent service.

Sean was a professional and performed his job excellently.

Monte and his partner (Bobby) were great! We have never experience this kind of service from other kind of business. They took their time to make sure that it was done correctly, not rushing to get things done. We will definitely recommend them to other people or business.

I am very satisfied - fast -everything is prompt and nice workmanship thank you Jonathan at Ace Plumbıng & Rooter.

Excellent work, very reasonable, great guy!
