"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Since my current water heater was 17 years old I decided to replace it before it gave out on me. I emailed Better Water Heaters in the evening with the details and got a phone call from Frans who scheduled Daniel to come and give me a free estimate the next afternoon. In the meantime I got another quote from another installer after texting photos of the current installation. Daniel’s estimate was similar for a standard water heater replacement but although I had not considered a tankless install I asked for a quote on that as well after discussing pros and cons with Daniel. Daniel then waited while I discussed this with my wife and since he could do the install the next day I decided on the tankless install and Daniel arrived the next morning and completed the install in three hours. I am very happy with the quickness and quality of the work as well as the quality of the Rinnai water heater that was installed."

"I met Gert when we hired him to replace our Tankless water heater. I was so impressed with is knowledge and concern to make sure the installation was neat and clean. The piping is literally a work of art. We met with Gert and Sergio to discuss the next phase. They removed all the galvanized pipe and installed 3/4" copper with a true hot water recirculating line for Tankless recirculating pump. Before they started work, they came in and placed protective covers over the hardwood floors. Sergio and his team replaced all the cast iron drains with ABS. They even opened walls where needed to get to the old galvanized drains to the sinks. They pulled up toilets and replaced the old flanges with new ones. All that's left is the sewer line from the house to the street. We will be calling Gert and Sergio when reach that point. Gert, Sergio and the whole crew have something you do not see that often anymore. That's integrity and concern for their customer. Also very conscientious of keeping our home clean."

"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."

"Jess was did a fantastic job installing a sewer clean out for us. We had a major backup, sewage had backed up into the tubs and he came out on a Sunday to address our emergency. He was very communicative and explained the whole process. I will definitely hire him for all our future plumbing needs!"

"Let me start off by saying I will definitely call Mike Counsil Plumbing and Rooter for my future plumbing needs!! I woke up to water in my bedroom closet from a leak coming from my water heater. I called Mike Counsil Plumbing and Rooter, I spoke with Deanna in the office and she was so patient and knowledgeable. She was able to get me an appointment same day. Their technician Abel came out and was able to advise me of what needed to be done. Lets say I have a new water heater and i'm very pleased. Very Grateful, Debra Torres-Sanchez"
