What Our Neighbors Say

Thank you to Seth, who came on Wednesday and fixed one of our two toilets and fixed our primary bedroom shower. And thank you to Charlie, who came today and replaced our other toilet and replaced our garbage disposal. You are both lifesavers! Our weekend (and going forward) will be MUCH nicer now that we can use our bathrooms (and garbage disposal) again. Highly recommend Clarksburg Plumbing.

Excellent service today from John Brown and Madeleine S. They were very kind and took time to explain the issue with my dishwasher. I really appreciate their professionalism and efficiency. I would definitely consider using this company again based on my service today!

GREAT service and expertise! John and Maddie just installed a water filtration system to our home. The process took one day to install and then they came back from the 48 hour install period to ensure everything was working well. John was familiar and knowledgeable about the water system we bought. Maddie and John kept our space clean, clearly explained how to ensure longevity for our system to last, and the difference it will make in our home. We appreciate their hard work and professionalism. This is our second time using Clarksburg plumbing. We would highly recommend their company to our family and friends.

We had a good experience with Clarksburg Plumbing: it was easy to schedule, they communicated clearly, arrived on time, and did a great job on completing the work.

Great

John did Excellent job with installing water refrigerator line for my refrigerator. My Condo was built 1983, and pipes were complicated, but not for John. He found it easy and finished the job in the timely manner. I am very happy customer. Thank you John!!

John Brown was knowledgeable, responsive and pragmatic. He saved us time by diagnosing then recommending best course of action. We are now waiting for the estimate for the project and will be going with Clarksburg Plumbing on our 1948 cap cod renovation. Highly recommend this company’s knowledge, professionalism and responsiveness.

Franklin and his crew showed up promptly and communicated great with us to help limit disruption with the tenants at 4 of our building. Unfortunately for us a second water main leak occurred the day before. But luckily for us they were able to stay on site another 2 days and knock the second one out, even staying till 8pm to find the line and get it repaired. These will be the guys I request for our next time needs

Seth and Brady did a fantastic job replacing our water heater. They were professional, courteous, and detail oriented. They arrived on time and did careful, clean work all the way through. We have worked with Clarksburg Plumbing on smaller items before this and would be very happy to utilize their services in the future, as well.

John and maddie were exceptionally professional and did an most effetive job in installing a expansion tank on our water heater.

Brady did an excellent job. From the time I called to the time the repair was completed was within 4 hours

We were very happy with the service we received today from John and Maddie. They were both very professional, ran the necessary tests to confirm the issue, and explained what they were doing step by step. They wore the protective booties to keep the floor nice and dry from the rainy weather too. Thank John and Maddie for all your help!

Seth and Brady were great. Fair price, courteous, work completed quickly, and looks good.

John was amazing!! Friendly, knowledgeable and such a professional. First time ever having a women plumber, Maddie, who was talented, and very personal and professional. Great experience and I will definitely use Clarksburg Plumbing again

Excellent professional service.

Mr Brown was a real professional. I was expressed how everything was done in an orderly manner. I’m very satisfied with the plumbing work he completed. Thank You!!

Seth provided an estimate on 8/25 for upgrading my basement sump pump to a dual system. He explained the setup clearly and promptly reordered the exact Wi-Fi-capable model I requested before installation. Seth and Maddie returned on 8/28 and did a fantastic job. The system works great, and their professionalism was top-notch. Highly recommended!

John is very knowledgeable, friendly and professional. He does a great job of explaining things.

Katie and the Clarksburg Plumbing team were phenomenal. Katie came highly recommended, and it could not have been a better choice. During an emergency plumbing issue at one of the buildings we service, her team came right out and made it happen. It was a complicated situation, but they handled it from start to finish with great responsiveness, professionalism, and patience throughout the entire process. We greatly appreciate their help and highly recommend them.

The plumber from Clarksburg Plumbing who worked on my broken gas hot water heater was John Brown. John is an amazing plumber. He is extremely energetic, very efficient, has amazing knowledge about plumbing, and is very honest. He is also very friendly, considerate, and took the time to answer all my questions. He diagnosed the problem quickly (which was a defective burner assembly). Then when I showed him the manufacturer's warranty, he took the initiative to immediately call the manufacturer and order all the necessary parts (which were free under the warranty). When the parts were delivered, he made sure to show up the next day and install the parts. As we talked throughout his time in the house, I could see that he has very deep knowledge of plumbing, which gives me confidence that his work is top quality. I also had a problem with very high water pressure in the house. The pressure regulator had to be replaced. John, working with Maddie, did a great job in fixing that as well. After the work, everything was cleaned up completely.

The best plumbers in the Bethesda area! We have worked with over 4 companies and none could figure out our issue until we called Clarksburg. They are honest, flexible and communicative. Wonderful experience from start to finish.

John and Maddy were excellent! Professional and beyond. Not only did the effectively fix our kitchen leak, but gave solid recommendations to fix other problems in advance. Appreciate them! Arrived on time, came quickly . We are definitely using this company for the rest of our remodeling planned. Thank you again. Doug Frankel Cost was no issue. They stand behind their work as they did today

Knowledgeable technicians who explained everything in detail and did a great job installing my new water heater.

We had our first experience with Clarksburg Plumbing & now we're sold! Charlie replaced our powder room toilet & did a great job. We moved to our house 3 years ago (& needed a new plumber) so we're happy to a great plumber now. Highly recommend!

Booked an apt with Clarksburg plumbing at 7am and by 9am they were at my house. Seth was a great tech that explained anything he was doing and answered my questions. would use Clarksburg plumbing again.

Highly recommend John Brown from Clarksburg Plumbing LLC! Yesterday John flushed and descaled our tankless water heater. We've gotten used to waiting and waiting for service people. That's not the case with John. He arrived pleasantly early for both the initial visit (for a no-cost estimate) and for the actual service call. He was personable, knowledgeable, and very patient with our many questions. He really helped us understand the ins and outs of this new-to-us technology of tankless water heaters. We're already recommending him to our neighbors!

John and Maddie were professional and customer focused. They completed several plumbing projects efficiently and verified my satisfaction with the work. John diagnosed a plumbing problem for future remediation. Great people and company.

I had Clarksburg Plumbing come out for a minor home plumbing repair. Seth and Maddie were on time, friendly, and professional. They provided a free estimate, and I went ahead with the repair. The repairs took just under 2 hours and I was completely satisfied with the service. I will definitely use Clarksburg Plumbing again in the future. Thanks, Seth and Maddie!

We had a very good experience with Clarksburg this year. A new fresh water pipe from the street and cleaning the waste pipe. From Brady in the office to John Brown and his team on site (Franklin and Chris) everything went smoothly, successfully, and on time. Would highly recomnend!

Charlie S. was efficient and friendly. He also answered some of my plumbing questions which I greatly appreciate. I will be using Clarksburg Plumbing in the future.

I recently used Clarksburg Plumbing for a condo repair of my main water turnoff valve and my outside hose bib. It required coordination with DC Water and the condo, and Clarksburg was extremely helpful, professional, and patient in the process. They came out a few times to evaluate and troubleshoot the issues, and then ultimately performed/made the repairs. Garrett and John Brown were the first to help, both very kind, knowledgable and highly skilled, and then Pablo (along with apprentice Tevon) made the final repairs. Not only did they do a great job, explaining everything to me in the process and checking after the water was restored to the condo, they also helped out one of the other owners that was having a sudden, luckily minor issue, as well. It’s a relief to know that I finally have a plumbing company that I can rely on for any future issues.

John Brown & Maddie did a great job with installing our new sump pump and battery backup--very informative, patient and thorough.

Many thanks to John and Maddie for their excellent work and cheerful attitude.

Pablo was responsive & efficient on a late Sunday evening. Thank you

We had a fire at our house 3-Jul-2025. Our contractor used Clarksburg Plumbing for all of our plumbing needs as we rebuilt our house. Pablo was with us from the beginning until all work on the house was completed a year later. Pablo was the lead plumber from Clarksburg Plumbing. He worked on the plumbing rough-in in December through February this past winter in bitter cold through the end of July 2026 when work was finally completed. Pablo quietly does his work. It’s clear that he is very skilled but he is not arrogant in any way. Rather, he is very engaging, takes suggestions under consideration and employs them as warranted, and is always kind even when I interrupt his work. Pablo represents Clarksburg Plumbing very well. It was my pleasure working with Pablo.

John & Maddie were great to get me scheduled for a potable water replacement

Properly identified the source of my leak after multiple other plumbers/companies couldn’t figure it out. Were thorough in explaining what they were doing, how they arrived to their determination, and gave advice on how to proceed with next steps that were outside their scope of operations. Thanks Pablo and Tevon

So grateful for you all, after 10 years and multiple plumbers your techs Garrett and Brady found the problem in 10 mins. Professional, friendly, knowledgeable, and we are more than satisfied with the work. Great company, great employees. We have a plumber now!

We had a severe blockage in our kitchen sink drain, causing water to back up into both the sink and the dishwasher. Seth and Brady arrived on time, quickly identified the issue, and did an excellent job clearing the kitchen drain. They also fixed the dishwasher drain line, which is now working perfectly. They were professional, efficient, and courteous throughout the process. I highly recommend them to anyone needing plumbing services.

Recently had an issue with my hot water heater in the restaurant I worked at. Clarksburg plumbing was quick and efficient and I was lucky enough to get John and Maddie as my techs! They were knowledgeable and helpful and fixed the issue in no time. I can’t recommend Clarksburg Plumbing enough and especially John and Maddie. They were honestly wonderful.

John and his assistant, Maddie, replaced an outside water valve and reviewed plumbing in a bathroom. They did excellent work, gave good advice and were friendly and nice. We were pleased with the work and will contact them at Clarksburg Plumbing for any plumbing needs in the future.

John was very knowledgable and provided all the details I needed to make my decision on what I wanted. Matty give me the exact estimates to consider. They were very curteous and professional. Thank you.

John and Maddie arrived on time and were professional and kind! All issues were resolved without issue! Highly recommend!

Happy we called them. It is refreshing to deal with a company a company with great customer service and honest techs. Highly recommend you call them.

Seth was very professional, quick and efficient. Also kind and personable.

Franklin, Chris and Colton, are hard working knowledgeable. They are polite and friendly. They ran into some issues replacing my out side water line. The problems were solved. They cleaned up all debris. I would request this crew if I ever have another plumbing issue. Thank you guys!

Highly recommend Clarksburg Plumbing! They accommodated my schedule right away. John and Maddie were amazing!! They took care of my pipe repair quickly and efficiently! 10/10 recommend!

John and Maddie were the ultimate professionals. Came on time. Clear estimate. Excellent work fixing my pressure relief valve, which had been improperly installed by another plumber. Clarksburg are my go to plumbers from now on.

Arrived on time, explained entire process, had plan a,b,c, in place, Did the best job I could ask for, and even show me the hole in my main line in the pipe. Highly recommend this company for all your plumbing needs.
