Recommended Customer Reviews

John just installed our toilets in our new home and fixed a leak under our sink. He was very knowledgeable and it was clear we hired the right guy. He took his time and explained everything to us and he is very personable. We feel much better now everything is done. We highly recommend Alt pluming and will use them again.

I found alt plumbing in the area. Never used the service before. received a call right away. I had a slab leak. John came out and detected the leak right away. He corrected the issue and advised of what needed to be done and why. Work was completed. I was very satisfied with the professionalism and how John handled our stressful situation. He advised this is very common issue.We had issues with our insurance company. John was very helpful in explaining the situation to the claims dept. I would recommend Alt plumbing to everyone. If you want someone to get the job done and who is honest. Use his services. His services are one of a kind. I found a plumber after all of these years, Thanks John for your help and dedication.

Alt installed a tankless water heater for us 5-7 years ago. It has been running smoothly ever since.
Yesterday, our family returned home after an 8 day vacation. The fridge needed some purging, and, in the process, my husband put some old rice & shredded chicken down the disposal. The double sinks backed up. We have had similar experiences, and have been able to clear it up ourselves, as the clog was local, in the pipes right below the sink, Not this time! After approximately 9 hours of DIY attempts, including two trips to Home Depot, & installing a new garbage disposal (because the current one sprung a leak in the process), we literally threw in the towel!
Travis arrived within the quoted time frame, quickly summed up the situation, and went to work. Thankfully, it was an easy fix. Putting too much stuff down the disposal, after a week of our plumbing being only minimally used during the pet sitter visits created a soft clog 30 or so feet from the sink on the way to the main line. He was able to snake the line and resolve the clog within 30-35 minutes of arriving. He also educated me on other things we could check and attempt if we encounter a similar situation in the future!
Good people, honest, reliable, & reasonable service fees!

Fixed the clog and gave me helpful advice on other plumbing issues. I really want to recommend you guys but you were two hours late with minimal communications. I hope that improves in the future.

John called to apologize for the tardiness and the lack of communications. Also gave me a coupon. Five star customer care!

John came out same day....so nice to have a good honest plumber on call. He communicated with me throughout the day so I knew all of my options and I knew what to expect. He cleaned out my clogged drains and found roots in my main drains.....gave me some great advice on how we can solve the potentially big issue. I will definitely use alt plumbing again.
