Diagnosed & fixed
Repair or full replacement
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.
What we do
Sewer line services
From a single broken section to a full replacement, diagnosed with a camera and fixed right.
Sewer Line Repair
Targeted excavation and spot repair of broken, cracked, or offset sections of your sewer line.
Sewer Line Replacement
When a line is collapsed, badly rooted, or past its life, we replace it with modern, long-lasting pipe.
Camera Inspection
We scope the line first so you see exactly what is wrong and only pay to fix what is actually broken.
Root Intrusion Removal
Tree roots are the number one sewer killer. We clear them and repair the damage they cause.
Trenchless Option
Less digging, less yard damage. See our dedicated trenchless sewer repair page for how it works.
Sewer Cleanout Installation
Adding or upgrading a cleanout so future service and camera access is fast and affordable.
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.

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.
The crew that does the hard digs
A crew you are glad to let in
Sewer work is where experience matters most. Our own trained, background checked crew handles excavation, repairs, and full replacements every day, and we leave your yard as close to how we found it as we can.

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 needed a water valve installed for my new fridge and a new faucet installed in upstairs bathroom. Seth was amazing. He came out and really listened to me and my concerns. We even called the company that was going to deliver my new fridge so he would have a better understanding of what he needed to do his job. It made me feel at ease with the whole process. He is even coming back later in the week to install new fridge once it’s delivered. I will absolutely call them again.

Amazing experience with Clarksburg Plumbing LLC! Our well pump needed replacement. Seth showed up right on time, was very professional, knew what he was doing and pricing was fare (they showed me all estimates upfront and explained everything). Any future plumbing needs and Clarksburg Plumbing will be my first call. I’ll also ask for Seth by name if I can get him!!

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!

Seth was absolutely amazing! He was very courteous and knowledgeable about his profession. He arrived on time and worked the entire time. He kept me in the loop the entire way as to what he was doing. He diagnosed two leaks within our toilet system and readily fixed them. Clarksburg Plumbing should be honored to have such an amazing employee as him.
Good questions
Sewer line FAQ
What homeowners ask us most about sewer repair and replacement.
How do I know if I need a sewer line repair or a full 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.
What causes sewer lines to fail?
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.
Do you have to dig up my whole yard?
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.
What is the difference between traditional and trenchless sewer repair?
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.
How long does a sewer line repair take?
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.
How long should a new sewer line last?
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.
What areas do you serve?
We serve Clarksburg, Germantown, Gaithersburg, Rockville, Damascus, Potomac, North Bethesda, and the surrounding Montgomery and Frederick County area.
