We just noticed an Allen Key was left behind on our kitchen counter. The price was considerably more than I expected. When we sold our electrical business in 2023 our service charge for two men in a stocked truck was $175 for the first 30 minutes and the same for each additional hour plus materials. Material prices have skyrocketed since then ( I check them at Home Depot every now and then. We weren't paying $4.00 a gallon for gas either.

We have trusted Clarksburg Plumbing for a few years and they always send someone out quickly and fix our problem quickly.! Today was the same! Charlie came to our house to look at one of the pipes coming from the hot water heater that was spraying water. He was able to diagnose the problem quickly and give us two options to choose from to fix it. Charlie’s knowledge of plumbing was evident in how he explained the problem and the options to fix it. After we chose the option we wanted, he began his work to fix it. His expert skills and abilities were evident in his amazing work. Charlie is also very respectful and kind, and easy to talk to. We highly recommend Clarksburg Plumbing and especially Charlie for all your plumbing needs.

An Exceptional Professional Who Sets the Standard for Quality Service! I highly recommend Charlie without reservation! He did an outstanding job today completing repairs to my home following a water leak, and his level of professionalism, expertise, and workmanship exceeded my expectations. Charlie is the kind of professional every homeowner hopes to encounter. He approached the repairs with care, precision, and an obvious commitment to getting the job done right. His attention to detail, knowledge, efficiency, and pride in his work were evident throughout the entire process. He didn't just complete the repairs; he demonstrated a level of accountability and dedication that gave me confidence in the quality of the work being performed in my home. I would specifically request Charlie again and recommend him to anyone without a second thought. If you are fortunate enough to have him assigned to your home, you can expect someone who takes his work seriously, respects your property, and delivers quality service. He represents the kind of professionalism and customer care that builds trust and distinguishes a company from its competitors. Charlie is an incredible asset to his organization, and his work deserves to be recognized by both management and customers. Companies build their reputations through employees who consistently demonstrate this level of skill, integrity, and commitment. Charlie, thank you for an exceptional job! You didn't just meet expectations; you set a standard worth recognizing. I would recommend your services in a heartbeat!

A terrific, reassuring experience getting me through a broken sewer line emergency which required digging up and replacing 20 ft of cracked, aging sewer line that had a belly. Everyone I worked with at Clarksburg was professional, competent, and efficient. The price was reasonable as well . Special shout out to my excavation crew: Noah, Markell, and Deybis headed by Jason. Thanks to Garrett and Cris who did my initial emergency intervention, snaking and diagnosis, Teyvon, John and Brady who helped with the hydrojetting, camera, and advice on how to prevent recurrence before pipe replacement. On a previous occasion, I had a great experience with Tyler who checked for a toilet leak and caulked. Finally, I greatly appreciated the comforting attention of the excellent reception staff Charlotte and Katie. Much appreciated Clarksburg Plumbing!

I had an absolutely wonderful experience with Clarksburg Plumbing LLC, and especially with Seth. From the moment he arrived, he was professional, respectful, knowledgeable, and quite frankly, a breath of fresh air. I was extremely nervous about the situation because my leak was below the main water shutoff valves, and the water had to be turned off at the street. Seth immediately put me at ease and assured me that everything was going to be okay. Rather than just putting together a temporary solution, he wanted to make sure he ordered the exact parts needed to do the job properly. Seth told me he expected to have the correct part and be able to return on Wednesday to complete the repair. On Tuesday afternoon, the office called to let me know the part had arrived and confirmed that Seth would be back Wednesday morning between 8:00 and noon. Seth was at my door at 8:10 AM! I was genuinely impressed. He completed the repair carefully, explained everything he was doing, and was extremely conscientious about properly turning the water back on, opening the faucets in the house, and making sure everything was working exactly as it should. What impressed me most, though, was Seth himself. He has a wonderfully calm, professional demeanor that made a very stressful situation so much easier for me. I sincerely appreciate the care he took with my home and the respect he showed me throughout the entire process. Clarksburg Plumbing is very fortunate to have someone like Seth representing their company. I would absolutely recommend them and Seth!!

I had a great experience with Tyler when he came out to replace our toilet flushing system. From start to finish, Tyler was incredibly courteous, professional, and knowledgeable. He walked me through what needed to be fixed, answered all my questions patiently, and completed the job efficiently. It’s rare to find such high-quality service and attention to detail. Everything is working perfectly now, and he left the work area completely clean. I highly recommend Tyler for any plumbing needs!

Absolute best plumbers I have ever used. Needed them a few times recently and each time they were so professional, kind and resolved each problem the first time around. This last issue took them several hours to fix. They explained everything along the way and gave a very fair price for a lot of work. They also work very cleanly! I will never use another plumber! I wanted to add a new review but I could not so I am editing my previous one. I had to use Clarksburg Plumbing again today and like last time, they were exceptional. I was fortunate enough to have John and Madeleine as my service technicians. I will always request them going forward. They are kind, professional and knowledgeable! I am sure the company knows how fortunate they are to have them as part of their team!

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.
