We had a pinhole leak suddenly appear in our outdoor hose bib, and Clarksburg Plumbing was able to provide next-day service, which we really appreciated. Our technician, John Brown, arrived right on time after giving us a 30-minute courtesy call. John quickly diagnosed the problem, explained everything clearly, and provided an accurate assessment of what needed to be done. He completed the repair in under two hours, and the quality of his work was excellent. Before leaving, he even took the time to share some helpful tips on how to prevent similar issues in the future. John was friendly, professional, knowledgeable, and efficient from start to finish. We couldn’t have asked for a better service experience. I highly recommend Clarksburg Plumbing and especially John Brown for anyone needing reliable, high-quality plumbing work.

Cris and Franklin from Clarksburg Plumbing did incredible work at our home fixing an underground water service leak. They encountered complications but went to plan B efficiently and skillfully and got the job done well and in a timely manner. They also answered all our questions patiently and taught us a lot of why they made the decisions they made. We are very pleased with their work and plan to recommend them and all of Clarksburg Plumbing to our friends and neighbors.

We had a clog in our septic line. The Clarksburg Plumbing crew located the troublesome area using a camera and then removed the clog and tested the line. They then remounted the toilet with a new wax ring and cleaned the area. Overall, a great experience!

Had a great experience with Clarksburg plumbing. Franklin and Chris were excellent! They clearly explained every step of the process. They kept any mess to a minimum and cleaned up the work area extremely well after the job was done. The office also amended our invoice to remove a line item that was in our estimate, but didn’t need to be done after all. We are extremely happy with Clarksburg Plumbing from the estimate to completion!

Was very Satisfied with Garret Kline work on our water heater at earth animal Riverstone. As I helped him he taught me a lot and showed me somethings here and there of industrial water heaters. My boss was very satisfied he got our plant back in production and overall very satisfied. Especially since we stayed together till almost 9:30pm installing everything. Very good tech and very professional with his job and for these reasons we are glad to say that any plumbing needs our company has we will be calling Garret for he is our go to plumber.

Looking forward to working with Clarksburg Plumbing and John again on regular maintenance for the home. And I am comforted to know that I have John and his team available to me in case of emergencies. Thanks John !

We contacted Clarksburg Plumbing to have the drain and faucet connected for our new powder room sink. Plumber and apprentice were on time. The drain pipe had to be replaced to connect to new sink location. The apprentice completed the work with instruction and supervision. I only gave four stars because they were onsite for approximately 30 minutes and charged us $641. They were professional, and cleaned up after themselves. I just felt like perhaps we should have gotten a second quote. it seemed expensive but I haven't had plumbing work done in several years.

#1 call for the #2 pipe. Ben and his assistant promptly connected a new cast iron riser to my existing sewer lateral, keeping my project in progress. I’m doing my own plumbing in the bathroom and have pro tools and experience, but this tie-in was a job for a real pro and I’m glad I called them in. With a wife and 3 daughters, every day on our water system is a heavy flow day, and downtime needed to be minimized. As an engineer I ask lots of questions and he was patient and answered them. Bravo Zulu!

I called that morning, they had someone (Tyler) out that same morning. Mind you, this was for a routine job. Tyler arrived; listened to my long, drawn out explanation. He diagnosed it within minutes, explained the issue, how he would fix it, and got to work. He also let me explain an additional issue I was having but instead of charging me to fix it, advised me to take the issue to the company that has lifetime warranty. 10/10 would recommend and use again!

We’re homeowners in Upper Marlboro, MD, and after the 2026 snowstorm we woke up to a near-overflowing sump pump and water seeping into our basement; every homeowner’s nightmare. Even after replacing the pump, water kept coming through the foundation, the sump pump was running every 90 seconds, and a pool of water formed along our backyard property line. After a waterproofing company heard water moving under the foundation, we called Clarksburg Plumbing, and everything changed. Their specialized team arrived the very next morning. We received a text ahead of time introducing our specialist, Franklin, and his expertise, which immediately put us at ease. He and his team (Cris, Colton and Deybis) were kind, calm, and incredibly knowledgeable. They quickly identified a break in our exterior water line. From there, Clarksburg Plumbing handled everything; utility markings, inspections, and the repair, efficiently, cleanly, and professionally. The issue was resolved, and our peace of mind restored. We’re truly grateful and would recommend Clarksburg Plumbing without hesitation to any homeowner in Upper Marlboro dealing with unexpected water issues.

We had Clarksburg Plumbing replace our main water line from the street into our home. Franklin, Chris and Colton arrived about 8:45am and started right to work. By a little after 12noon the new waterline was installed and leak-free. They used the trenchless method so they only had to dig up a small area of the yard to connect the new line to WSSC. The guys did a great job! They were very courteous, explained everything they were doing and answered all of our questions. The inside work area was spotless when the job was complete and the hole in the yard was fenced for safety until the inspection. Two days later Omar and Tavon arrived to fill in the excavated soil after the inspection. They made sure to tamp and pack the soil well. The sod was placed on top and they also spread grass seed on the area. The job was completed quickly and they did a great job! We highly recommend Clarksburg Plumbing !

Good questions

Frequently asked questions

Quick answers to what homeowners ask us most.

It depends on the clog and the method needed, but we always give upfront, flat pricing before any work begins, so you approve the price first. Drain cleaning is one of our more affordable services. Call us for a quick estimate.

Replacement usually makes sense when you have repeated backups, multiple cracks or heavy root intrusion, a collapsed line, or older Orangeburg or cast iron pipe. We run a camera inspection first and give you an honest repair versus replace recommendation.

If you notice hard water spots, scale on fixtures, dry skin, an odd taste or smell, or you are on well water, filtration can help. We test your water and size the right system for your home.

Yes. We are available 24/7 for plumbing emergencies across Clarksburg and the surrounding area. Call 301 972 2223 any time and a real neighbor will help.
