"On 10/27/2027, I had to find a plumber to repair my water heater that had stopped heating water. I went online to Angi?s website and received 3 different plumbing companies in the Austin, TX area. One of the companies was 5-Mile Plumbing Co. The owner of the company, Elvis Bernal, contacted me. We discussed the issue with the water heater. Mr. Bernal gave me his assessment and provided me with a bid proposal on the cost of the repair. Mr. Bernal came to our house the next day and immediately started work on the water heater. I watched Mr. Bernal from a distance and asked questions regarding the procedure. Mr. Bernal went out of his way to answer my questions. During his work, Mr. Bernal also saw something else that needed replacement on the water heater and immediately left the house to go purchase the part. Mr. Bernal replaced the part, continued the repair and verified one of the heating elements had gone out. A new heating element was installed and Mr. Bernal ?bled? the"

"I was disappointed that he arrived late because as he said "he forgot". If he is tech savvy enough to use Apple Pay (which was really great firme) the one would think he should be able to set reminders for his appointments so he doesn't forget. I now seem to be having issues with my water heater and I'm vacillating about calling him again?"

"Replaced my outdoor faucet quickly that I couldn't budge with my tools. Answered all my other plumbing questions. Price was high, but I've never seen a plumber or electrician charge less than a couple hundred no matter how simple. I have peace of mind though with the year warranty."

"I had a water heater fail on a Sunday morning. I submitted a request and got a response in less than a minute. The person was extremely helpful and we arranged an install only a few hours later. I couldn't be happier with the service and attention to detail. *This review was migrated from an affiliated account on Angi with an original submission date of 2/18/2021."

"I called inquiring about problem with water taking 5 minutes to become hot in Master bath but other areas in house were normal. Mario said a water heater pump might solve the problem. I agreed to try and Mario came out at the appointed time, installed and explained operation of the pump and it worked like a charm. I was very happy with their knowledge, efficiency and service. Have used them on a couple of other occasions with same satisfying results."

"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.
