First diagnosed with a leaking from the hot water valve. Second diagnose was deteriorated caulking around the sink edge. 2 days after fixing the caulking, leak happened again in the same area. Tried to let the plumber to follow up inspection for a week, plumber missed the appointment, and no response ever.

I highly recommend Mavson plumbing to anyone looking for a dependable plumber, especially when you need help in an emergency. I’ll definitely be calling him again for any future plumbing needs!
John installed a 50-gallon gas water heater and removed the old one for us. He was professional, courteous, and friendly. We are very happy with his service.
I had John drain/ flush my water heater. He was very professional and walked me through the process. He was responsive and over has very good work ethic on this job. Would highly recommend!!
I’ve hired pros for plenty of projects on Thumbtack, and John from Mavson Plumbing Services LLC is hands down a 10/10. Honestly, I have finally found the plumber I’m going to use for the rest of my life. I needed my water heater temporarily removed and also wanted shut-off valves installed for my unit. That might sound simple, but my condo is in a very old 1940s building with an old-school setup and multiple shared water supply lines coming in. I had several other plumbers come look at this project before John, and I was given so much wrong information. Other plumbers couldn't even figure out where the water was coming in, and they kept telling me I had to get permission to shut off the water to the entire building just to remove my water heater. John showed up right on time, walked in with total confidence, and immediately knew what he was looking at. Instead of just guessing, he actually tested the lines right in front of me and showed me why what the other plumbers told me wasn't true. We didn't need a building-wide shutoff to get the water heater out, and he clearly mapped out and explained what actually needs to be done to install shut-off valves in my unit to separate my water from the rest of the building. He really listened to how I wanted everything set up. When he needed a specific part, he ran to the store, came right back with the exact piece, and got it done. You can see his skill and pride in the small details—like how neatly he capped the fittings, asked how I preferred things along the way, and tested everything in front of me so I knew it was 100% solid. He even cleaned up after himself and charged a very fair, affordable price that actually made sense. Just an amazing guy and a true professional who goes above and beyond. If you want a plumber who actually knows his craft, hire John!
John was amazing!
John was awesome. I learned quite a bit from him during his visits. One for the initial and second for the installation. I would highly recommend him to anyone needing this service. Thank you again John.
Extremely responsive to an emergency request. He was able to get the job done within cost and with the highest level of professionalism. He also made us aware of a danger that the unit present and mitigated that problem during his visit.
Mason Plumbing's, John Henry, did an amazing job. He was knowledgeable and efficient.
Great work! Super responsive!
John is very knowledgeable and gave great price for water heater replacement.
Hey, the team did a great job. They came and took care of our garden hose that was constantly leaking.
John Henry did an awesome job. Was professional, cared about the quality of work and made sure to educate me on the new water heater post installed. I just had to show him the old water heater then the water shutoff and he was able to get the job done.
John replaced a hot water heater for me. I would hire John again in a heartbeat. Considerate, straightforward and got the job done quickly. He even came out on a Sunday so that I didn’t have to go longer without hot water.
Absolutely incredible experience with John. He was extremely knowledgable and creative in getting us the best solution for a tricky water heater install in an old house. I could not recommend him more and I will come back for all my plumbing needs
John was fantastic from start to finish. He responded immediately to my project with an assessment and a very reasonable quote. He arrived promptly the next morning and quickly determined that the issue was actually with the sewer line. He explained what he found and the necessary price adjustment, which was still extremely reasonable and less than I’ve paid in the past for similar work, and he did a better job. While working in my basement, John also noticed a hose that was showing signs it could fail soon. He pointed it out, explained the issue, and replaced it for me. I really appreciated his attention to detail. John was pleasant, informative, considerate, and, most importantly, he felt honest. No unnecessary upselling and no dragging out the job. He came, diagnosed the problem, did the work well, and was done. As a homeowner, there’s something really reassuring about feeling like, “I have a plumber now.” That’s how I feel about John. I’ll absolutely call him again and highly recommend him.
John did an outstanding job replacing my water heater. He was prompt, honest, and took the time to explain every step of the process. His pricing was fair and reasonable, especially compared to major retail plumbing companies that quoted me nearly three times the price without taking the time to educate me or explain what was needed. During the installation, John noticed my water heater was missing an expansion tank and a vent. He gladly installed both and clearly explained why they were important for the safety, performance, and longevity of the system. He also identified another issue that no one else had pointed out. He explained that copper pipes should not come into direct contact with certain metals because it can cause galvanic corrosion (oxidation), which was the reason my copper pipes had turned green. Rather than leaving the problem, he replaced all of the affected copper piping and made sure everything was installed correctly to prevent future issues. What impressed me most was his attention to detail and the meticulous care he put into every aspect of the installation. He was polite, courteous, respectful of my home, and cleaned up thoroughly before leaving. John also took the time to teach me more about my home's plumbing system, which I truly appreciated. It's rare to find someone who is not only highly skilled but also willing to educate their customers. His honesty, craftsmanship, and professionalism are second to none. If you're looking for an honest plumber who will diagnose the problem correctly, fix it right the first time, provide expert workmanship, and charge a fair price, choose this company. They have earned my trust, and I will definitely be calling John for all of my future plumbing needs. I highly recommend them.
