"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"Jaymie first visited to review our need for correcting a pre-existing faulty installation of a tankless water heater. He grasped our concerns at once, joined us in brainstorming a relatively simple solution, and produced a financially reasonable bid on the spot. We accepted it as far more reasonable than other bids. He arranged to have the work performed by his company within a few days. At the appointed time, Jaymie himself arrived to do the job, which pleased us greatly since he already knew exactly what needed to be done, making it unnecessary to brief a new workman. He is a very competent, friendly, and helpful person. We would not hesitate to call on him for any future plumbing needs."

"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."

"Replaced a filing water heater. The work was excellent. My water heater was basically blocked in by the incoming water and gas pipes, but the two-person team managed to remove the old heater, replace pipes as necessary, and get everything working again. Gave up-front pricing including permit inspection. Super professional crew."

"Jess and his crew did a great job recently repiping my house, both the water supply and drain lines. Jess is easy to work with and very responsive. His price was very reasonable. He came back promptly to fix some very minor issues I found (tiny leaks from the kitchen sink drain and from one of the outside faucets). Everything is fine now. The sprinklers in my backyard work better now because they're getting more pressure than they got from the very old galvanized pipes that were replaced. I'm happy to recommend him."
