The basics
The line that brings your water in
Your water line carries fresh water from the city main or your well into the house. When it leaks or breaks underground, you might see low pressure, wet or sunken spots in the yard, discolored water, or a spike in your bill, and sometimes no water at all. We pinpoint the problem first, then repair the bad section or replace the line, using traditional excavation or trenchless methods that spare your yard and driveway.

Catch it early
Signs of a failing water line
Water line problems waste water and money and only get worse. Spot these early for more, cheaper options.
Low or dropping water pressure
Weak flow throughout the house can mean a leak or restriction in the main water line.
Soggy or sunken spots in the yard
Wet patches, extra-green grass, or sinkholes over the line often mean a leak underground.
A spike in your water bill
A sudden jump with no change in use usually means water is escaping from the line.
Discolored or rusty water
Brown or rusty water can signal a corroding or failing line, common in older pipe.
No water at all
A full loss of water points to a major break or a failed main or service line.
Old or undersized pipe
Aging galvanized, poly, or undersized lines crack, corrode, and restrict flow over time.

What we find
Why water lines fail
Water lines do not last forever. Most failures we see come from corrosion in older galvanized or copper pipe, ground that shifts and settles, freeze damage in harsh winters, and aging poly or undersized lines that crack under pressure. We confirm the cause before we dig.
- Corrosion in galvanized and older copper pipe
- Cracks from shifting soil and settling
- Freeze damage during Maryland winters
- Aging poly and undersized service lines
Built for Maryland homes
Why this matters here
Many homes around Clarksburg, Damascus, and Montgomery County still run on aging galvanized or poly water lines, and our freeze-thaw winters are hard on buried pipe. Whether you are on WSSC water or a private well line, a failing line wastes water and money, so we locate it precisely and fix it right.
- Watch for pressure drops and unexplained bill spikes
- Know your pipe material, especially in older homes
- Insulate exposed lines before freezing weather
- Ask about trenchless to save your yard and driveway
Less digging
Ask about trenchless
For many water lines we can replace with little or no digging. See how it works on our trenchless page.
The crew that does the hard digs
A crew you are glad to let in
Water line work means digging, and digging means experience matters. Our own trained, background checked crew handles repairs and full replacements every day, and we put your yard back as close to how we found it as we can.

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!

We thank Clarksburg Plumbing again for superior, high quality and friendly service! ----- Clarksburg Plumbing visited us last week to repair an external spigot that had been leaking. The work involved creating a little inside access panel. Within and without, a nice, neat job by Charlie and his understudy apprentice, Chris. Problem solved and happy campers here! ----- UPDATE: Plumber John Brown presented himself on time and got right to work replacing my Mom's ancient leaky kitchen faucet with a new store-bought one that I provided. During the process, Mr. Brown detected and showed me two other problem areas contributing to the water leaks: a cracked drain pipe and then rusted threads on the sink trap. He efficiently and expertly repaired all three elements to our full satisfaction. Plus, John is a super nice guy, completely honest and classy enough to laugh at all my corny jokes! The next time you need any plumbing work in your home or business, I strongly endorse John Brown and anyone on the Clarksburg Plumbing team! UPDATE 2: John and his understudy Maddie visited, and quickly solved the problem of a pinhole leak in copper tubing leading from our hot water heater. He advised us on other plumbing needs, for which we have scheduled and will otherwise follow-up. Thank you Clarksburg Plumbing for your top quality people - John Brown in particular - and performance.

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.

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.
Good questions
Water line FAQ
What homeowners and businesses ask us most about water line repair and replacement.
How do I know if my water line is leaking?
Common signs are a drop in water pressure, an unexplained spike in your water bill, soggy or unusually green patches in the yard, discolored water, or hearing water running when nothing is on. We use leak detection to confirm and pinpoint it.
Should I repair or replace my water line?
A single break or leak in an otherwise sound line can be spot repaired. If the line is old galvanized or poly, corroded throughout, or has repeated failures, replacement is the better long-term value. We show you the findings and the honest math.
Do you have to dig up my whole yard?
Not usually. We locate the problem precisely so we dig only where needed, and for many water lines we offer trenchless replacement that requires little or no digging.
What is the difference between traditional and trenchless water line replacement?
Traditional replacement excavates a trench to reach the line. Trenchless pulls a new line through with one or two small access points, sparing your driveway and landscaping. We offer both and recommend what fits your property.
Do you repair commercial water lines too?
Yes. We handle water line repair and replacement for businesses, rentals, and multi-unit properties, with minimal disruption to your operations.
How long does a new water line last?
A properly installed modern water line can last 50 years or more. We use durable materials and proper bedding so the repair outlasts the problem.
What areas do you serve?
We serve Clarksburg, Germantown, Gaithersburg, Rockville, Damascus, Potomac, North Bethesda, and the surrounding Montgomery and Frederick County area.
