"Just had my system installed today and cannot be any happier. I found The Water Doctor here on Angi's list and I am glad I did. I just bought my first house and have lived in San Antonio my whole life so I know hard the water can get. First, Patricia came over to test the water and gave me information regarding water treatment that no other salesperson seems to have the same knowledge of. She went over every system tier, any questions I had, and the ways to pay and discounts. They are straight forward and honest which is how I like to conduct business. Install was scheduled within a couple of days of the paperwork. Hugo and his team was so professional and showed me the ins and outs of the water system. With the tier we got, we get a supply of natural soaps which we are big on so ask about that! I highly recommend the Water Doctor if you need any water softner needs!"

"Very pleased with Shawn Jackson and his helper. They made quick work of replacing the water heater. I recently had knee surgery and couldn't lift the salt pellet bags so they did me a favor of loading my water softener with salt. Shawn and his helper were cordial and professional. George Plumbing is the company I'll always call."

"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."

"Very responsive and quick service.  Followed the quoted price for work even though there was an unanticipated problem on the outside hose bib replacement that caused the repair to take longer and require additional tools.  Gas line repaired to better than original installation.  On the air conditioning service Bobby checked both our systems out and during the checkout he found that the installer had failed to remove the plugs to allow condensate overflow to drain properly.  He fixed that and also installed a safety switch on each system at my request.  I have attic units and one of them is right over a room where I have a couple of computer systems.  I was always was always worried about the possibility of a condensate leak and the damage it could cause.  Not worried anymore as these fixes gave me plenty of redundancy and assurance that such an event will be prevented.  Highly recommend them for gas, plumbing, and air-conditioning services as i have now used all three.

"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."

"Main water supply leak. GREAT JOB!! Highly recommend!! King's Plumbing called as soon as I posted and was able to come right out. The area of the leak was obvious and Dez gave me a fixed price of $900. I had another "over the phone estimate" of $600 from Ft Worth but was going to be another day for them to show up. Dez went right to work and only took 2.5 hours to dig about a four-foot hole to find the leak then fix. It was 40 yr old tree roots pushing on a joint. It would have taken me several days to do myself, without water. Definitely worth the cost."
