What a sewer camera inspection shows
A sewer camera inspection puts a waterproof camera on a flexible rod and pushes it through the cleanout toward the street or the septic tank. The plumber watches a screen, records the run and notes the pipe material, joint condition, roots, cracks, offsets and low spots. You receive the findings in plain language.
This is a planned service, and we schedule it when you need information instead of a repair. If the camera finds a problem that needs urgent work, the plumber explains it right away, and our sewer line repair page covers the next steps.
When an inspection is worth booking
Not every house needs a camera. These situations are where the footage saves money.
- You are buying an older home and want to know the lateral's condition before closing.
- A drain has been cleared twice in a year and still slows.
- A cable stopped at a certain distance and could not pass.
- You see roots in the cleanout or smell sewage outdoors.
- A previous repair needs to be confirmed with footage.

How the visit runs
The visit is mostly about getting a clear look, and the plumber keeps the process short.
- Find access. The plumber locates the cleanout or uses a toilet pull if none exists.
- Run the camera. The rod moves in steps while the plumber watches the screen and records distance.
- Locate problems. A locator above ground shows the depth and path of any damage.
- Review the footage with you. You see the same pictures the plumber sees, and the plumber explains what is normal and what is not.
What the plumber looks for on the footage
Each finding has a typical meaning, and the plumber explains how it affects you.
| Finding | What it usually means | What follows |
|---|---|---|
| Roots at a joint | Water leaks out and roots follow | Cutting, then repair or lining |
| Offset joint | Pipe sections have shifted | Spot repair if short, replacement if severe |
| Belly or sag | Water pools in a low spot | Replacement of that section |
| Scale on cast iron | Old pipe is narrowing | Jetting or descaling |
| Clean, intact pipe | No action needed | Keep the footage for your records |
Buying or selling a home in Derry
Real estate in Derry spans very old village houses and later construction, and the age of a home hints at its pipe material. Clay and cast iron appear in older lines, while plastic appears in newer ones. An inspection tells you which you have and what shape it is in, without guessing.
If your house is on a septic system instead of a town sewer, the camera is still useful on the line between the house and the tank. Tell the dispatcher which setup you have when you book. We also serve Londonderry, Windham, Hampstead, Chester and Salem, and most inspections can be scheduled for the same week.
After the inspection: your options
You get a clear price before any repair. If the footage is clean, you pay for the inspection and move on. If it shows a small issue, you can monitor it, and the plumber suggests a timeline. If it shows a failing pipe, the plumber explains repair, lining and replacement, and you can compare quotes using the footage.
Many owners pair an inspection with sewer line cleaning so the camera sees the pipe wall instead of grease. The plumber advises whether that helps your case.
Older houses in the Upper Village are a common reason to look before repairing. See plumbing in East Derry for what the public record says about the area.
Sewer Inspection questions in Derry
Many inspections take about an hour on site. A long line, heavy debris or a hard-to-find cleanout can add time. The plumber tells you the expected time when scheduling.
Ask for it when you book. The plumber can describe the findings and share the recording or still images so a buyer, seller or other contractor can review them.
Often yes. The plumber may pull a toilet or use a roof vent to access the line. If access is hard, the plumber recommends installing a cleanout so future work is easier.
No, it is a planned service, so it does not need an emergency visit. If water is backing up, call the 24/7 line for sewer line cleaning first. A camera check often follows once the line is open.
You decide what happens next. The plumber explains the finding, the risk of waiting and the repair options. Nothing is done without your approval.
