Cohasset trenchless sewer repair
We line Cohasset sewers through one planned access point instead of a trench along the whole pipe. Our camera recording shows where that access goes and how much of your sewer the liner renews.


One opening or a trench
We open one access point, not your whole Cohasset sewer route.
Excavating your sewer means digging along its full length to reach the pipe. Lining needs access at one end of the run we renew: an existing cleanout when your pipe allows it, or one planned opening where our equipment connects to your sewer.
We choose that point from your recording and show it to you before anything is opened. Your lawn, driveway, landscaping or basement floor along the rest of the route stays in place.
Excavation. A trench along the length of your sewer to remove the pipe.
Access opening. One planned point where our equipment connects to your pipe.
Our recording. It shows where that point goes and how far the liner reaches.
Slide across these pipes to see what one access point lets us renew.
We renew your lined run from its end and leave the old pipe in the ground.




We renew corroded cast iron without digging it up.We descale your pipe from the access point, then cure the liner against its wall.
Our Back Bay job
We planned one floor opening for a lateral under a finished Back Bay floor.
In the Back Bay the owner’s cast iron lateral ran under a finished floor, and excavating it would have meant opening the floor along its route. We mapped the lateral with our camera, planned one access opening for our equipment, then lined it from inside and reinstated its connections. We plan your access opening the same way.
That job is in Boston, not in Cohasset. It shows how we decide where one opening goes before we make it.
We line your Cohasset sewer from one access point in five steps.

We record your sewer from a cleanout.
We map your sewer’s route, depth and condition to choose the access point.
Hydro jetting
We clean your pipe from that access.
Jetting clears roots and scale so your liner seats against the old wall.

We connect our inversion drum at the access point.
Our drum feeds the resin-saturated liner into your sewer from that one point.
Curing the liner
We cure your liner along the run.
The resin hardens into a new pipe wall while the ground along your sewer’s route stays in place.

We record the result and close the access.
You see the finished run on our recording, and we close the access point as we agreed with you.
These findings decide where your Cohasset access goes.
Some problems can be lined from a cleanout; others need an opening at a particular spot.
Camera inspection
Roots are entering your joints.
We clear and line them from a cleanout when one gives us a straight run.
Camera inspection
An offset sits partway along your sewer.
If our liner can pass it, the access stays at the end of the run; if not, the offset needs its own repair.
Camera inspectionSpot repair first
Part of your sewer has collapsed.
That section needs an opening at the collapse for a spot repair before we line the rest.

Cohasset sewer rules
Cohasset’s sewer board licenses the drain layers who repair your service.
Cohasset runs its own sewer department and is not an MWRA sewer community. Its Board of Sewer Commissioners issues the Drain Layer’s License needed for locating, relocating, modifying, upgrading, repairing and connecting sewer services, and no work on your sewer service connection or lateral starts until you, as the property owner, have a connection permit from the board.
An access opening for our equipment is a small, planned hole; excavating your whole sewer is a trench along its route. When your recording shows a lateral we can line, we tell you where any opening goes and what Cohasset needs before it is made.
Owners describe how we treated their homes and yards.
Our customers rate us 5.0 out of 5 from 56 Google reviews.
We had original 100 y/o cast iron under our basement slab and Boston Pipe Lining handled the stretch from the house to the street. It was 12 feet underground which would have been astronomically expensive to dig. The price was fair and they were extremely professional. Travis and his team were in and out in less than three hours and there was not a single issue with the process. I'd strongly recommend them.
Richard R.Google review, We had a GREAT experience with Boston Pipelining Company! From my initial outreach to the completion of the project they were absolutely terrific. They were professional and showed great respect for my home and property. Probably the BEST experience I've had in a long time -- no issues or concerns whatsoever!
Linda W.Google review, Boston Pipe Lining Company came quickly to assess the situation and give me a quote, and got my sewer line fixed quickly with no hassle. It took far less time than I expected for them to line my pipe. Travis was very friendly and honest.
Tim B.Google review,
We work in Cohasset and the South Shore towns around it.
We inspect, clean and line your Cohasset sewer.
We answer questions about access openings in Cohasset.

How big is an access opening?
Its size depends on your pipe’s depth and the equipment we connect. In Charlestown we tied our inversion drum into the sewer through an opening in a tiled basement floor instead of opening the slab along the run.
Is my Cohasset home on the town sewer?
Cohasset’s sewer department publishes a sewer district map. If your home drains to a septic system, tell us, because the pipe we would record runs from your house to your tank.
Who restores the area around the opening?
We agree the location and the restoration of any opening with you before work starts, so you know what will be opened and how it is closed.
Ask us where your Cohasset access would go.
Tell us your address, where your cleanouts are and what covers your sewer’s route.
