We diagnose it with a camera, then repair or replace it across Clarksburg and Montgomery County, with traditional excavation or trenchless methods that protect your yard.

The basics

Repair or replace, decided by camera

Your main sewer line carries everything from the house out to the city sewer or your septic system, and when it fails, no amount of drain cleaning will keep it clear for long. We start with a camera inspection so we can see the real condition: a single break, root intrusion, a sagging belly, or a line that has reached the end of its life. Then we recommend the honest fix, a targeted repair or a full replacement, using traditional excavation or, where it fits, trenchless repair that needs far less digging.

4

Backfill & restore

We backfill, compact, and restore the area as close to how we found it as possible.

Catch it early

Signs of a failing sewer line

Sewer problems only get worse and messier. Spot these early and you have more, cheaper options.

Repeated sewer backups

A main line that backs up again and again, especially in the lowest drains, is failing, not just clogged.

Multiple drains affected

When tubs, toilets, and floor drains all gurgle or back up together, the main line is the cause.

Sewage odor in yard or home

A persistent sewage smell can mean a cracked or broken sewer pipe leaking underground.

Soggy or sunken spots in the yard

Wet patches, extra-green grass, or sinkholes over the line often mean a break leaking below.

Slow drains everywhere

Whole-house slow drainage points to a restriction or damage in the main sewer line.

Old clay, cast iron, or Orangeburg pipe

Older Maryland homes often have pipe materials that crack, corrode, or collapse with age.

Think it's your sewer line? Let's camera it and find out.

What we find

Why sewer lines fail

This is a real sewer pipe we pulled out, completely choked with tree roots. Roots are the number one cause we see, but lines also fail from age, corrosion, shifting soil, and sagging bellies that trap waste. A camera inspection tells us exactly which it is.

Built for Maryland homes

Why this matters here

Many homes across Clarksburg, Damascus, and Montgomery County are old enough to still have clay, cast iron, or even Orangeburg sewer pipe, and they are surrounded by mature trees hunting for water. That combination is exactly what cracks and clogs sewer lines, which is why we always scope before we dig.

  • Get a camera inspection if backups keep coming back
  • Know your pipe material, especially in older homes
  • Address root intrusion before it collapses the line
  • Ask about trenchless to save your yard and driveway
Less digging

Ask about trenchless

For many sewer lines, we can repair or replace with little or no digging. See how it works on our dedicated trenchless page.

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.

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

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!

Good questions

Sewer line FAQ

What homeowners ask us most about sewer repair and replacement.

It depends on the condition of the pipe. A single break or rooted section can often be spot repaired, while a collapsed, badly sagging, or widely deteriorated line usually needs replacement. We camera the line first and show you the footage so the decision is clear.

The most common causes are tree root intrusion, age and corrosion of clay, cast iron, or Orangeburg pipe, cracks from shifting soil, and bellies that sag and trap waste. A camera inspection identifies exactly which it is.

Not usually. We locate the problem precisely with a camera so we dig only where needed, and for many lines we offer trenchless repair or replacement that requires little or no digging.

Traditional repair excavates down to the pipe to fix or replace it. Trenchless uses one or two small access points to reline or replace the pipe with minimal digging. We offer both, and cover trenchless in detail on its own page.

A spot repair can often be done in a day, while a full replacement may take longer depending on length, depth, and access. We give you a clear timeline with your estimate.

A properly installed modern sewer line can last 50 years or more. We use durable materials and proper bedding so the repair outlives the problem.

We serve Clarksburg, Germantown, Gaithersburg, Rockville, Damascus, Potomac, North Bethesda, and the surrounding Montgomery and Frederick County area.
