"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

"Our water heater started leaking and needed to be replaced. Called in the morning and had someone out in the afternoon. This was actually our second quote. The first guy only gave the heater a cursory look before quoting a price. The Better Water Heaters technician actually examined the heater, plumbing and electrical connections before discussing options. We discussed replacing the original and switching to a tankless system. After we did some research and asked some friends who had a tankless system, we decided to go with the tankless. We scheduled an appointment for the next day and had it installed. Very smooth, very professional."

"The complete process from the quote, to scheduling, to the installation of the tankless water heater was excellent. It only took one week from quoting through the completion of the job. The installation was completed in one day. The team was cordial and professional. Furthermore, the price was competitive. I would strongly recommend Super Brothers for your plumbing jobs."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"The contractor showed up on time and installed the water heater in a couple of hours. They hauled the old heater away and cleaned up the surrounding area very well. Will certainly have them do other plumbing jobs in the future."
