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.

How it works

How a sewer repair goes

Clear steps, no surprises, and your yard put back together when we are done.

1

Camera & locate

We scope the line to see the damage and locate it precisely, so we dig only where needed.

2

Honest estimate

We show you the footage and lay out repair versus replacement, with upfront, flat pricing.

3

Repair or replace

We excavate and fix the section, or replace the line, with traditional or trenchless methods.

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.

Highly recommend John Brown from Clarksburg Plumbing LLC! Yesterday John flushed and descaled our tankless water heater. We've gotten used to waiting and waiting for service people. That's not the case with John. He arrived pleasantly early for both the initial visit (for a no-cost estimate) and for the actual service call. He was personable, knowledgeable, and very patient with our many questions. He really helped us understand the ins and outs of this new-to-us technology of tankless water heaters. We're already recommending him to our neighbors!

I had Clarksburg Plumbing come out for a minor home plumbing repair. Seth and Maddie were on time, friendly, and professional. They provided a free estimate, and I went ahead with the repair. The repairs took just under 2 hours and I was completely satisfied with the service. I will definitely use Clarksburg Plumbing again in the future. Thanks, Seth and Maddie!

I recently used Clarksburg Plumbing for a condo repair of my main water turnoff valve and my outside hose bib. It required coordination with DC Water and the condo, and Clarksburg was extremely helpful, professional, and patient in the process. They came out a few times to evaluate and troubleshoot the issues, and then ultimately performed/made the repairs. Garrett and John Brown were the first to help, both very kind, knowledgable and highly skilled, and then Pablo (along with apprentice Tevon) made the final repairs. Not only did they do a great job, explaining everything to me in the process and checking after the water was restored to the condo, they also helped out one of the other owners that was having a sudden, luckily minor issue, as well. It’s a relief to know that I finally have a plumbing company that I can rely on for any future issues.

We had a fire at our house 3-Jul-2025. Our contractor used Clarksburg Plumbing for all of our plumbing needs as we rebuilt our house. Pablo was with us from the beginning until all work on the house was completed a year later. Pablo was the lead plumber from Clarksburg Plumbing. He worked on the plumbing rough-in in December through February this past winter in bitter cold through the end of July 2026 when work was finally completed. Pablo quietly does his work. It’s clear that he is very skilled but he is not arrogant in any way. Rather, he is very engaging, takes suggestions under consideration and employs them as warranted, and is always kind even when I interrupt his work. Pablo represents Clarksburg Plumbing very well. It was my pleasure working with Pablo.

Properly identified the source of my leak after multiple other plumbers/companies couldn’t figure it out. Were thorough in explaining what they were doing, how they arrived to their determination, and gave advice on how to proceed with next steps that were outside their scope of operations. Thanks Pablo and Tevon

We had a severe blockage in our kitchen sink drain, causing water to back up into both the sink and the dishwasher. Seth and Brady arrived on time, quickly identified the issue, and did an excellent job clearing the kitchen drain. They also fixed the dishwasher drain line, which is now working perfectly. They were professional, efficient, and courteous throughout the process. I highly recommend them to anyone needing plumbing services.

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.
