"After lining up three plumbing contractors to install a kitchen faucet, a garbage disposal and fix a drainage leak, I selected Superior Plumbing to do the job because their technician seemed to have the necessary professionalism for a good job and they were also the least expensive of the three contractors I contacted. My service tech Armin was on time, cheerful, courteous and knowledgeable. It was obvious that he cared for my particular needs and he even announced that he loves his job and always looks forward to doing things right. He took almost exactly the time that was originally quoted and did an excellent job, cleaning up thoroughly before leaving. I wouldn't hesitate to use their services again. Thanks Armin."

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Went really well. The installer showed up and only had one of the two toilets. He called Mike who then immediately drove another toilet to our location to be installed. Since it was a deal, I was worried they would install a low quality toilet to improve their profit. Instead, they installed Toto toilets which are known as one of the highest quality toilets on the market. Price was good too as most places I called wanted $300 just to install a toilet. Deal price was $450 including the toilet, installation, and haul away of the old toilet."

"Three men were sent to get everything cleaned up in a day. They also arranged for the plumber to go and make the pipe repair the next morning so that my tenants were not inconvenienced for more than one day. They did a very good job cleaning and sanitizing the area."

"When we purchased the house, it was a 30 year old home. Almost everybody in the period of five years to seven years wanted to convert to copper plumbing. So what they offered at that time was anyone you referred to if they chose to use their service, you have $500 cash payment which was really nice because half of our neighbors and our family members used them. I do not know what they do now, but it is a really nice service because they are a very good company. They did a great job."

"They do a good job. For just a toilet, some plumbers charge a lot of money and I just found them to be good. The best parts about them is their availability, promptness, and getting the job done. They were able to work with really old pipes. I was impressed with that. My husband thinks that the price was too much on one of the jobs, but I say that probably is a tenth of what they have done. They have done a lot of jobs for us. It was a terrible job that they had to do the last time they came, but they did it."

"They did come out and do the work. Its been a year since I had them out I know I spent more, I had them do more work. They actually clean out and did a couple of faucets for me and they ended up breaking a counter top. And they had quite a time getting it resolved. They didn't want to pay for the, they broke a sink that's what they broke. The bathroom had two matching sinks and they couldn't match the sink and they didn't want to pay for two of them, they just wanted to do one and put an un matching sink in there. So I ended up paying for one sink, they paid for another and then they installed the faucets but it was not a great experience with Benjamin Franklin Plumbing."
