ExcellentFlow Masters Plumbing Inc5.0 Based on 234 reviews fromSee all reviews review us onDan KnoxDan Knox ★★★★★ Chris and Conor were great. They were very patient and fixing our water heater required more than a few steps. I’m sure most people would have given up. Top review for them both!!!Martin ConnollyMartin Connolly ★★★★★ Flowmasters are extremely professional and courteous. Their technician arrived on time and took care of our blocking drain and fixed a faulty sump pump in a timely manner with minimal disruption.I highly recommend Flowmasters for all your plumbing needs.Laura ForstLaura Forst ★★★★★ Flow Masters Plumbing was recommended by the manufacturer of our water heater when the plumbing company that originally installed the unit and had managed the plumbing needs of our home before we purchased our house for years could not get us on the schedule for at least 6 months...Flow Masters got us an appointment right away and was timely and communicative and professional...Conor gave us a competitive estimate and was able to easily schedule the service soon after. The tech, Christian M., was great, prompt and courteous...explained what he was doing and gave updates and did not leave a mess. Flow Masters Plumbing went above and beyond and we now have a new plumber.Brad WallaceBrad Wallace ★★★★★ Flowmasters came out same-day to deal with a clog and Conor did a great job. Very communicative about when they would show up and arrived as promised. Friendly, professional, and competent. I will call them again.Nilus de MatranNilus de Matran ★★★★★ Great service. Would use again and recommend to friends.John GouwsJohn Gouws ★★★★★ Arrived on time, worked very quickly and very friendly. Thank you, Conor!Response from the ownerHi John, Thank you for your kind words! We're glad Conor could help. Have a great day! Kat RainsKat Rains ★★★★★ Flow Masters is awesome. I called in need of a timely inspection and they were quick to accommodate. The company communicated clearly when Conor had left for the job site and he arrived very close to the start of my two hour window, it was awesome as I was waiting outside in my car getting an estimate for a client. He even worked that night to provide me with the formal estimate which I needed before my clients put in an offer on a house. As a Realtor, I need a plumber I can rely on and I've found them.Response from the ownerHi Kat,Thank you so much for your kind words and for sharing your experience!

We look forward to assisting you again in the future.Cheers! jose rosariojose rosario ★★★★★ I was referred to Flowmasters due to their professional experience with commercial and residential areas. I had a really bad unprofessional experience with a recent plumber that I had to fire from the job. The stainless sink was damaged from the top and bottom and the plumber did not want to make things right by taking shortcuts. Contacted Flowmasters and the next day they showed up, gave us a quote and came two days later. Juan showed up, went straight to work, installed both sinks and that was it.. No drama, with a couple of laughs together, and even talked about soccer. This is the experience every person should have with contractors or workers. Pricing is competitive and came out cheaper than my previous plumber who failed to finish the job. From now on, even if Flowmasters will be on the high side of quotes, rest assured the quality will speak for itself.Thank you so much for fixing the mistakes my previous plumber did to us.Response from the ownerHi Jose,Thank you so much for your awesome review! We're thrilled to hear that Juan and our team could help turn things around for you. We're glad you enjoyed the experience and the laughs. If you need anything in the future, we're just a call away!
