Prompt and very knowledgeable - Juan G did an excellent job! We are very pleased.

Here at our warehouse we had our bathrooms both backed up and due to the complicated plumbing lay out we were really worried about our options. Being part of a wonderful network of professionals I’ve met thru my time with my company I asked anyone if they knew a plumber that would help us. One text and a phone call later with a simple brief of my situation they were here fast and took care of the issue quick efficiently and even let us know not only what the issue was but what to do to avoid future issues. For our first service they have solidified themselves as our exclusive service not only for us but anyone in need of a great experience. Thank you to Juan the technical expert and Fergal the owner for making sure we were good from beginning to end.

Flowmasters are easy to deal with, friendly and timely. Juan is swell. He did a great job diagnosing, quoting and installing a new faucet and garbage disposal. He patiently answered my questions and explained the situation. Scheduling was flexible. I am recommending Flowmasters to neighbors.

Love these guys …. They’re professional, clean, timely, communicate well, priced well and above all, honest. They’re my new go to. Highly recommended

Juan was awesome - he did multiple random jobs for me over the last few weeks. He’s literally the kind of dude who is up for anything. Like, if you had some crazy idea of installing a toilet on the outside of your house on the balcony, he would suggest a seat warmer because it might be cold and he would go out and buy it. Or if you wanted to build a pool on your driveway - he’ll ask what kind of tiles or design you want on the inside. He’s always super fast, efficient, easy to communicate with and does great work.

They always have our back, no matter when the plumbing emergencies happen. Juan Garcia was dogged about finding the source of the clog and finally did! Love these guys.

Fast, efficient and got the work done, the right way. Have total faith that they can handle anything else I need done in the future!
