"HIRE THEM. If you are thinking about installing a brand new, or replacing an old water treatment system, you must trust The Water Doctor to take care of you. I almost decided to install a new water softener on my own, and I am so glad I did not. The quality of work of the instillation, and the knowledge transfer associated with the responsibility of having a treatment system in your home were worth the decision to hire a professional. They take care of you from first dial to get a quote through installation, to follow up and reassurance weeks past installation. Their prices are extremely competitive, and it gives you a piece of mind behind these appliances/units in your home. Thank you Water Doctor!"

"My water heater, was about 15 years old, finally started leaking from the base. Now, I have a Home Warranty (AHS), and they were very expedient assigning me to a company to come and see if they could repair it. When the company came out, they gave me estimates, three to be exact. Each estimate was sufficiently more expensive, but it is a water heater replacement, so I understand. For the replacement, they were going to replace the previous model with a comparable. Again, I understand, but chances are, I was overpaying for a outdated and less efficient model. So, after they provided me with their estimate, I Googled best contractors to replace a water heater. I was looking for the reviews, and with the reviews, I only ever look at the 1-3 stars. Well, I found George Plumbing Co. formerly known as Yell For George Plumbing (funny story, if you hire them, please ask why George called it, “Yell for George Plumbing”), and they had 4.9 out of 5 stars (557 reviews) on Google, 4.4 out of 5 stars (58 reviews) on Yelp (They really should have closer to 5 stars) Many of those 1 stars, were very petty. If you rely on Angie’s List, they have a 4.9 out of 5 stars, with 303 reviews, there. If you see or look at Trustpilot, you will see the review is a 2.1, but please make sure you are looking at the right company, as they are George Plumbing out of the United Kingdom. So, please make sure that you are reading the right reviews for the right company. Anyway, just know that I looked at every consumer review site that I could find, even the BBB, which, I normally don’t trust, but still looked. Don’t waste your time, I absolutely disagree. They used high quality equipment, the technicians/contractors were absolutely amazing. Nathan and Austin, were very professional, explaining what they found, how they would remedy it, and what I can do to extend or prolong the life of my new water heater, based on what most likely caused the one being replaced to go out. Both Nathan and Austin, were active listeners, ensuring to address each of my concerns, before the work, during and upon the completion of the work. As with many houses, 10 plus years old, there was a lot of new codes that increased the cost of the work, to bring it up to code. Not only did they correctly explain it to me, but I had already research and talked to the city and county to see what codes my previous heater needed updating. They were right on the money. Another important concern was the warranty. I was happy that they both explained the details of it, made themselves available to contact after hours for any questions I might have forgot to ask. Believe me, I texted, and Nathan replied, in short order. Both Nathan and Austin are very experienced, but also patient, and have a very high level of attention to detail. When they arrived to diagnose the leaking one, my garage was an absolute mess. They even took the time to clean up, my mess, and treat the area that was damaged by the leak. They were very expeditious as well, both taking their time, but not wasting my time on unnecessary explanations. They were both a pleasure to have work on and in my home and I will definitely be using them again if I need too. Of course, I hope I never need to again, just saying… They also took the time to clean out and empty my water softener, which was quite full of sludge and sediment, that contributed to the previous water heater’s decline. I highly recommend George Plumbing Co, so if you need them, please call (210) 495-9991. Any other George is simply not worth your time. Oh, one more thing, the gentleman who runs the office, either Mica, possibly Micah, was very professional and took care of me as a military veteran. Thanks again. If you made it this far, I hope my review was helpful, because I very rarely give reviews, let alone a 5 star one."

"Parker and Sons sent out two guys to quote installation of a tankless hot water heater.  They were very responsive and flexible in scheduling time to come out.  They were also very punctual and professional.  They weren't as thorough as some of the other companies that came out, but perhaps that's just knowing what they have to do.  Where I was let down was the price. The quoted prices was 2X the cost of the other two companies I had out to quote the same job.

"The technician came on time and, although it took him longer than expected to install the system, he installed it and demonstrated the system for me. The next day, I noticed there was still water on the concrete close to the system but, I figured it was residual water. Apparently the system was leaking. Two days after install I contacted Leaf and advised them that the system was leaking. Early, the next business day, they arrived and repaired the leak and made sure I was happy. My system seems to be working well and I am satisfied."

"Revilla’s plumbing did a great job with locating the leak in my bathroom, repairing the leak and coordinating the remodel. Tim is very well connected and we were able to treat the affected area to prevent mold through a relationship vendor he trusts and does business with on a regular basis. Since my bathroom remodel, he has replaced my water heater, a water heater for my parents and some faucet replacements around my house. I trust Revilla’s plumbing will do the job right at a fair cost."
