Kaleb, Komin and Ty were awesome! They replaced the water heater at my aunt’s house while I was house sitting. They were professional and respectful at all times. Kaleb was informative throughout the entire water heater replacement. After installation was complete, Kaleb explained what was done, how to know if it’s working correctly and what to do if it’s not. They cleaned the work area. I would definitely recommend them to family, friends and neighbors.

Big THANK YOU to the team (Amram, Liu’s, and Nay) for correctly diagnosing the drainage piping leak issue and then promptly correcting it! They provided periodic updates and educated me on cast iron piping. I reside in a townhome and the first two plumbing companies that came out via my home warranty incorrectly diagnosed the issue and left me with multiple access cuts in my drywall as well as a broken water heater (yes the plumbers literally, inadvertently broke my water heater. With the John Stevenson plumbing team I learned how the pipes in my home are routed through the entire complex and the reasons for the damaged piping. I would gladly recommend this team/company to anyone dealing with corroded/cracked cast iron piping. I would admit the price is too expensive but I am confident I will not have any issue with this pipe for many years!

I had a great experience with Armando from John Stevenson Plumbing. From the moment he arrived, he was professional, friendly, and easy to talk to. He took the time to answer every question I had and explained everything in a way that actually made sense. He worked quickly but didn’t rush, and it was clear he really knows his craft. Communication was solid the entire time, which made the whole situation a lot less stressful. During the water leak, he was calm and reassuring, and even offered to help clean up the garage that meant a lot. It’s rare to find someone who’s not only skilled but also genuinely cares about the customer. If ratings went past 5 stars, he’d easily be a 10. I’m really glad I reached out to John Stevenson Plumbing and got connected with Armando. Highly recommend

We had an outstanding experience with John Stevenson and his plumbing team. From start to finish, they handled a major list of projects for us — water heater installation, multiple plumbing pipe repairs, a new toilet installation, and a whole-house water filter install — and every part of the process was smooth, professional, and expertly done. Our home is older and we were dealing with several pipe leaks. We were pretty anxious about what repairs would entail. Instead, John and his team made the entire experience as seamless and pleasant as possible. They were organized, efficient, and clearly highly skilled. Every step was explained clearly, timelines were honored, and the workmanship was top-notch. What really stood out, though, was the attitude of the entire crew. They were consistently smiling, upbeat, and genuinely kind. It’s rare to have contractors in your home who bring that level of positivity and professionalism together. They even took time to be friendly with our dog, Tulip — who absolutely adored them. That alone told us a lot about their character. The whole job was completed smoothly and with great attention to detail. We truly could not have asked for a better team of professionals. If you’re looking for plumbing work done right — with integrity, skill, and a great attitude — John Stevenson and his team are the ones to call.
