      Best water heater company ever!!

      Hydroflow were working on a radiant heat system next door to my house about a week ago, the guys had always said hello and been super polite working so we had a good informal repor.
      So leaving the house one afternoon i met garry the owner, we chatted about the waterheater in my house.Our water heater was having issues- some we were aware of (small leaks and brownish water problems) others we didnt realize (how slow it was to reheat the water) till we replaced it. I don't know the first thing about boilers or waterheaters, but the owner garry simply laid out the problems and explained both what was wrong and an options to fix it. He seemed extremely fair and walked me through all the steps and never even tried to sell me anything...gosh!! so refreshing!!

      My water heater was ten years old,out of warranty and an eye sore from the previous installer. Garry gave me a breakdown of what was involved to replace, a time line and price. $1450, i did check his price against others that evening when i got back home and realised he was very, very fair considering his expertise, i rang three other companies two of them were more expensive but all three were trying to push me so hard i decided i wanted to deal with a plumber and not a sales man.
      i've read so many bad tales about companies installing waterheaters and boilers wrong that i was hesitant but now i was trusting my gut.
      The next day i rang hydroflow, got talking to garry and just booked them in for the following day.
      They arrived on time, beautiful installation, the new water heater is more silent, more efficient and yes clean water!!!!!! i was so happy i tipped the guys $100... a small price to pay for peace of mind, a great job done and still so much cheaper than some of the "big brand" companies that are so informal!!
      Hydroflow have somthing that other plumbing companies lack, integrity!

      We've been in this house for 2 years and my hydronic system needed an inspection so I called HydroFlow. Gary and his team were prompt, professional, fast and very helpful. Sure enough, one of the expansion tanks needed to be replaced. He also noticed that the main's pressure was far too high (90psi) so we decided to add a regulator on the indeed. At the same time Gary and his team added a whole-house Moen leak detector. The price was fair and Gary, Angel and the rest of the team did a beautiful job on the installation.

      I am the vice president of our condo development that is totally hydronic. I first used Garry about a year ago when our pump went out. He attended to it immediately. Recently one of our homeowners heating system went out completely. They didn't know where to turn. I was able to give them the number for Garry and he quickly came over on a Friday night and assessed the situation. They needed a new water heater and two pumps that had gone out. Garry had the entire job fixed within two days, and they are so happy they found him.
      I can highly recommend Garry....he and his workers are very knowledgeable. If you are looking for a very competent hydronic contractor with integrity, call Garry first.

      Our Navien radiant heat was not keeping up with the cold weather this winter, so we finally called Garry when the original installer was unresponsive. He came out and quickly assessed the situation, ordered a part, and came back in a few days when the part came in and fixed the boiler. He also noticed our water pressure was too high so he installed a pressure regulator which has fixed other problems we had no idea were caused by excess pressure (faucets leaking, faucets difficult to turn). He also found a crushed filter in the system and replaced that. Garry was efficient, very friendly and trustworthy. We're happy we found him!

      I am a GC redoing a bathroom in an old Victorian in San Francisco. Garry and his crew were spot on with a couple things.
      1 they helped us simplify and solve a complicated drainage problem

      2 the client asked about a tankless water heater. Garry recommended the Navien. He and his crew took care of everything including pulling permits and dealing with inspectors. protip- check to see if you are eligible for green energy rebates - you might be pleasantly surprised

      Hydroflow definitely checks all the boxes - responsive, knowledgeable, on schedule and on budget.

      Recently had a water leak in my basement at my place here in the Richmond district.

      Hydroflow fixed my water heater the same day we found out about the leak. Great service, great work, and great communication!

      Highly recommend Hydroflow for plumbing service and install.

      Garry has done 2 great jobs for us in NoPa, SF. The first was a somewhat complicated conversion of a bathroom into 2 baths. Done promptly, and years later, we have had no problems. Recently, our hot water heater was not working. Called Garry who promptly responded and within a few hours, the problem was fixed. And he is a nice guy. What more can you want? Thanks Garry

      Just got our water tank replaced with this company. Emergency situation and this company was great from start to finish!
      Not knowing much about our options they talked us through all that was available, we ended up going with a tankless water heater which I hadn't heard of! Super happy with the outcome. Thanks again for making this as stress free as possible!

      All the positive reviews are so well-deserved and very reflective of my personal experience with Garry. He's an incredibly capable plumber and quite frankly just an all-around wonderful human being. I recently purchased a condo with underfloor radiant heating, which had quite a bit of crowning/lifting in the kitchen. I planned on addressing it with time, as I'd only purchased the place the week before....but as luck would have it, I ended up not having hot water the moment I moved in. After calling a few plumbers who came in and literally ran away after seeing the state of the building's mechanical room, I came across his glowing Yelp reviews and thought I'd give it a shot. He was able to restore my hot water (albeit briefly, because the problem was and continued to be the sorry state of affairs in said mechanical room), in addition to nearly much being a shoulder for me to cry on. It is actually pretty difficult to find honest people to help you with home stuff, and in your hour of dire need, it can be distressing to not know if you can trust people. Never once did I feel like I was being taken for a ride with Garry. I can't recommend him enough.

      Garry is a gent and a pleasure to deal with.
      My water heater had
      Broken down and stopped working so i was left without hot running water!I called around a few places but Garry gave me the best estimate which seemed very fair compared to other prices.
      It turned out my water heater needed to be replaced
      after he looked at it he went off and got a new one and plumbed it in for me with ease.
      I was a happy man with a new water heater and hot running water within 24hrs.
      Thanks for explaining the problem to me in dept too.
      Hydroflow is the way to go.

      If you're looking plumbing services in the San Francisco Bay Area, look no further. It's always stressful when you have an emergent situation like this- worrying about being taken advantage of.. I was referred to Hydroflow by a close friend and was throughly impressed from start to finish. They did an excellent job explaining what my options were for my aging water heater highlighting the pros and cons of repairing versus replacing. I felt confident in their recommendations and was updated throughout the process. I would absolutely use their services again!
