Tevon, Noah, Markell, and Morrow were sent by Clarksburg Plumbing LLC to repair an outside broken waterline They arrived at the appointed hour and completed the work in about 3 hours. I was very impressed with them and I would like to recommend all four of these very professional and friendly technicians. Clarksburg Plumbing is a fantastic organization; the office staff, Katie and Charlotte, who helped me are the best.

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.

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.

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.

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!

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.
