Roberto was the team leader who rebuilt our water heater system. This included not just replacement of an old water heater but rebuilding the platform for it as well as a second adjacent water heater so that both are now correctly strapped and conform to SF earthquake safety code. This was an all day installation…
FlowMasters is THE BEST at what they do. Responsive, friendly, reasonably priced, and they've done fantastic work every time we've used them.
FMP addressed several items on the Inspection Report. I am happy with the results & plan to call them again. Thank you to Sebastian, Oisin, & FMP team!
Flowmasters is an excellent plumbing and HVAC company. Miguel the HVAC technician is excellent. He was able to diagnose and repair my furnace in my attic in a hard to get to location. He is very knowledgeable and thotough. Overall FlowMasters has excellent plumbers and HVAC techs.
Very responsive and customer focused, Great Company. Alberto knows his stuff and he's easy to work with.
The tech seemed confused on how to handle the job (said they mainly do small repairs). On his way out he drove over my lavendar bush (it survived). Never followed up with an actual quote despite promising one soon. Big waste of my time. Would not recommend for complex jobs or generally due to lack of…
Cristian and Jose replaced our tankless water heater and did a fantastic job! They arrived promptly and were extremely kind, polite, and professional during the installation. Both of them went above and beyond the call of duty and we would definitely use their services again!
Technicians were knowledgable and efficient. Work was completed in the time frame given. Also very professional and courteous.
Prompt, courteous, professional service at a reasonable price
I use FMP for my home and for my clients that own industrial and office property.
Flow Masters did a great job coming up with a solution for our radiant heat and hot water at the faucet problems. Alberto and his team were extremely thoughtful, professional and tidy while in my home for 3 days. They may cost a bit more, though totally worth it for the workmanship and peace of mind knowing their work quality.
Easy to work with, always punctual. Willing to explain how my system works. I recommend as an honest and good plumber. Plus they had my hot water back in action within a day
Jose, Jonathan, and Alberto were all fantastic to work with, and did an amazing job installing a replacement heat-pump hot water tank for my home. Super professional with great customer service. The new tank with copper piping looked great, and they left with the area immaculate. Great job!
Hydroflush and Radiant floor heat repair.
Excellent service. I have used flow masters for several projects and appreciate their responsiveness and thorough work.
Miguel and Alberto from Flow Masters did a great job resolving an issue with my water heater, and the communication with the company was flawless.
I was very impressed with Sebastian and will very likely emply to reactivate a tankless water heater project I abandonded
Great job installing a new tankless water heater!!!!
I got a couple of bids on an electric heat pump water heater. Flow Masters quote and their quick answers to all my many questions gave me the feeling that they really knew what they were doing. My initial impression was correct; the installation was confident and professional. You can trust them on complicated projects.
My Triangle Tube Prestige Solo boiler for radiant floor heating was damaged by rodents. Flow Masters helped me to replace the unit including implementing rodent exclusion steps. The workers were on time and very knowledgeable and were able to do everything to my satisfaction. Flow Masters also repaired a number of…
Friendly, honest, fair price. I was happy with the boiler replacement
Gustavo and Roberto are excellent. When I asked them to install the water heater they come early as I expected. You don’t need to wait for a couple of days.
When our hot water heater went out we wanted to work with a company we could trust with skilled employees. Flow Masters Plumbing came out right away, diagnosed our problem and replaced the water heater the next day. Price was reasonable and everyone was a pleasure to work with. Highly recommend.
Alberto was prompt and remained in contact while resolving our plumbing issue.
If you’re looking for a company that takes its projects seriously, dedicates the time and it’s experience to their successful completion, offers multiple options to the owner and thoroughly explains each ones advantages and disadvantages,, then Flow Masters plumbing is the company to call. They have the proven…
The service was wonderful! They responded quickly, the plumbers were very friendly, and were able to fix the my plumbing with no issue. They did a great job!
Alberto was incredibly helpful & very communicative when our water heater started leaking. Got us set up & scheduled same day despite my many delays. He's incredible to work with and I highly recommend him. Plus he was able to workout an incredible water heater for us.
We have used Flow Masters for a few years. They did all of the original installation of our hot water heating and in floor heating systems. We continue to use them for our plumbing needs including our annual back flow testing. They have always been excellent - we would recommend them to anyone who needs a plumber.
What started as a forceful change turned out to be a great experience and my PREFERRED vendor now anywhere I go! I will also call Flow Masters Plumbing first before anyone else!
Quick turnaround and technicians were very professional. The finished work was excellent. Highly recommended!
HIGHLY RECOMMEND Flow Masters Plumbing. They are the BEST plumbing company I've worked with - communication is key and they excel at it. Punctual, patient, thorough, friendly and efficient. I don't have to worry when I have them onsite (at our apartment building) as I know they'll handle the job thoroughly and make sure everything is up to code.
Flow Masters is simply the best. They installed all the plumbing for a big home remodel, and all subsequent service, inspections, and repairs. I’ve always been completely satisfied!
We needed a new water heater, and our radiant furnace was also very old. Connor assessed the situation and proposed a new combination system to update both systems. Alberto and Yovany did an excellent job removing the old heaters and connecting the new heater to the systems. They did the job on time, on budget,…
Very impressive service. Professional and efficient. Estimate was accurate and no surprises. Highly recommend.
I noticed our tankless water heater was leaking at 345 pm yesterday. Conner from flow masters was at our house by 4:15. The tank needed to be replaced after many years and parts were no longer available. Conner arranged for his guys to changed the tankless water heater today. And the job is done. He is…
Flow Masters installed a high-efficiency combi-boiler to serve both hydronic heating and domestic hot water, neatly done to replace older equipment. One-year service just performed as recommended. I highly recommend Flow Masters as hydronic specialists.
Awesome job! Consummate professionals. Cheerful, tidy, fast— everything you want in a plumber.
Couldn't ask for a better group of people.
My htp Phoenix high efficiency water heater stopped working at the start of the cold snap, disabling my underfloor radiant heat and household hot water. Tired of service techs that did not know about my equipment, I contacted the manufacturer, which put me in touch with the regional sales distributor. Steve at…
We are building contractors here in San Francisco and we have relied on Flowmasters Plumbing for 10 years now. They are experts at installing radiant heating systems and are extremely knowledgable about all aspects of plumbing. Their customer service is efficient and reliable, their rates are competitive and I wholeheartedly recommend them.
Flow masters were on time very efficient in changing out my water heater highly recommend these guys to any one thank you !!
I had an amazing experience with Flow Masters. Our water heater failed on a Friday, and by Monday they had managed to source and install a replacement that has functioned perfectly. Conor and team were were super responsive and professional throughout.
We have had an excellent experience with Flow Masters. Connor Grant managed the replacement of our leaking solar water heater about a year ago. When other parts, not installed by them, also went out, they quickly came out and diagnosed the problem (which was not due to their installation) and got it fixed. Connor…
