Recommended Customer Reviews

Armando was out this morning and did a full home evaluation and addressed several issues we have in our home. He gave plenty of options and loads of detailed information to help me better understand the depths of the issues at hand. Armando put up with my barking and scared rescue dogs- cheers for that! He spent a massive amount of time at my home due to being incredibly detailed in his investigations and explanation to me.

well, it's been almost a year! john stevenson called this morning to schedule our ""free no cost to us service"" that we signed up for when they tanked the value, safety, and functionality of our house by putting plumbing outside
i wanted to update my previous review with some things we're still enjoying from john stevenson plumbing a year later.
1. outside plumbing. so pretty, right?
2. freezing cold water that takes forever to heat up thanks to the plumbing being outside! wim hoff method for your hands!
3. truly, the ugliest hardware and worst installation of it you've ever seen. it's installed crooked and they cut a giant hole for this monstrosity so the only way to fix it is to replace the entire tub
4. no self-awareness that your previous customers despise you! please keep me on your call list so i can continue to make sure these reviews stay live for your potential future clients

Signed up for Charlie's Care Club April of 2022. I was told this was an exclusive benefits package for the customer. The club is to include 4 in home evaluations and tune-ups. In 2022 I did not use the service as I should have. Since I had purchased the plan I have had them service the house on two occasions. The technicians are nice but know how to promote future repair work. Since I joined the Club in 4/2022 they have cancelled twice for the in home evaluation for plumbing and AC. The first cancellation was July 2023. This was for heating and cooling tune up only. They called me a day prior to the visit and told me that they are too busy with other customers needing service. The second in home evaluation was most recent for another heating and cooling tune up. This time I was called the same day after taking a half day off of work to be told they did not have enough technicians to provide service. Now I pay $12.99 a month to have this benefit for priority scheduling and discounts and system tune ups. As you can see it appears this program in my opinion is not worth being part (Charlie's Care Club) of. So think twice about joining and how much you would really use this Club. The time I took off work for them to reschedule twice this year was not worth the annual dues and loss income.

Originally had this company come out to service our water heater, they were friendly and recommended their monthly payment program to avoid large expenses in the future. We signed up, however, when they came out to flush our Navien 2 year old water heater, after flushing and at the re-assembly process he said there was a crack under the tape in the condensate trap and it began leaking. Please note he found the leaking part after a complete inspection and flushing the unit. We called the plumber that originally installed the water heater and they said it was not broken since it was brand new and it would have leaked right away. They put tape on the condensate trap due to the O ring was not enough to stop water from leaking. Per the attached picture it looks like the part was broken upon re-assembly by pushing the holding pins too hard.
We called the manager of John Stevenson plumbing and explained what transpired and that his technician broke our condensate trap and it is now leaking. The Navien water heater company said the parts are still under warrantee but they only work with plumbing companies. The person at John Stevenson, has refused to help us and we are now reporting him to the contractor's board to come out and replace the broken condensate trap.

I had this company come out to assess my HVAC system which was quite old and not working as it should. They quoted me for a new installation and I had them come out and do the work. They were very professional and efficient. However when they came out to do their one-year free check up, they quoted me a further $1,000 to repair/replace the duct work in the attic. As it was $9,000 for the initial work, I was left wondering why they didn't do this in the beginning. I had the feeling that it was a way to get further work and dollars, so I was very disappointed with the follow up.

Just had Stevenson coming out to check out house for small plumbing issue since just moved into this home. Brent came out and had his supervisor, Mike, came out to verify Brents' discoveries. Both very professional and knowledgeable. After reviewing replacing values under all sinks & toilets for leak prevention & discovering water heater isn't up to par, a new appointment set up to install brand new water heater and replace valves. Promptly came on time and worked most of day to complete the tasks. Luis & his partner finished the insttall & you would never know they were working in & out of the house.....left my house & property perfect. Thanks guys!!!!
Very very pleased to know my house is working without worries

I initially contacted Stevenson Plumbing as part of getting bids for a whole house filtration system and a descaling system for my home. They had been recommended by a family member. Joseph Wood was Stevenson's rep who came by and gave me several excellent ideas on how to proceed with the right system and system placement. He then worked with me to get an excellent priced written bid. I selected Stevenson for my project.
On my scheduled installation date, Technicians Blake D. and Buddy O. arrived on time following a text message that they were on the way with their picture and name. After a review of the planned project they made some excellent suggestions for minor installation modifications that improved my project.
They were on site for a little over four hours installing a Novo Whole House Filter and Flow-Tech Descaler. They were very polite and conducted themselves professionally. Their work was expertly done and completed to my satisfaction. They reviewed their work with me making sure all my questions were answered. They then provided me with all the written warranty info.
The day after the work was completed I got a call from Stevenson's Customer Service Department making sure I was completly satisfied and wanting to know if I had any further questions.
I was very pleased with the accomplished project, the price I paid and the excellent customer service. I certainly recommend them for anyone considering a major plumbing project.

Hire this company for all your Plumbing needs ! I am a first time client and a Realtor and want to say that it was a 5 Star experience across the board. I had a water pipe in my garage that appeared to be broken and was blasting water in my garage last night so I had to shut off the main water valve and go without water all night. I was so stressed over night worrying if the plumbing issue would be resolved effectively. I called John Stevenson plumbing first thing in the morning and the Receptionist was very delightful on the phone and scheduled me same day and even accommodated my busy schedule. I requested a Senior Tech and Travis who has been a Plumber for 10 years arrived on time and was very personable and friendly. Travis immediately found the issue causing my water leak and fixed it right away. I was amazed at how quickly he identified the issue and fixed my water leak. I GIVE TRAVIS 10 STARS AND HE DESERVES A RAISE ! THANKYOU TRAVIS AND JOHN STEVENSON PLUMBING. I WILL REFER YOU TO ALL MY CLIENTS. GREAT JOB !

Juan displays excellent leadership skills along with his outstanding quality of work. He is a true professional.

We scheduled a preventative maintenance check for our water heater through John Stevenson. Patrick came out at performed a thorough checkup on the water heater itself and also the faucets. I appreciate the 30 minute heads up before he arrived as well as the friendly and knowledgeable service. Best of all, Patrick found our water heater to be in tip top shape and didn't need any additional service. Great job!
