How to have the sewer line camera-inspected
A sewer camera inspection sends a waterproof camera down your main line to spot roots, sags, cracks and collapses. It usually takes 30 minutes to an hour and costs about $125 to $350 through an inspector, or $150 to $500 through a plumber. Always ask for the full video.
How a sewer camera inspection works
The pipe from your house to the city main is called the lateral, and in most places it's yours to maintain. Where your responsibility ends depends on your city. It may stop at the property line or run all the way to the main, and a few cities run their own lateral programs, so ask your sewer utility.
The pro feeds a camera on a flexible rod through a cleanout, and a recording shows distance markers along the line. Running water through the pipe helps reveal low spots. Pipe material shapes what they look for:
| Pipe | Common problem |
|---|---|
| Clay | Many joints, where roots get in |
| Orangeburg | Deforms and blisters; replacement is often advised |
| Cast iron | Internal corrosion and scaling |
| PVC or ABS | Durable, but can sag if poorly bedded |
The camera has limits. It can't see the outside of the pipe, the soil around it, or anything past a heavy blockage, and a clean result doesn't guarantee future performance. How often to repeat a scope depends on what the video shows, so ask your plumber.
Sewer camera inspection cost and repair prices
| Job | About what it costs |
|---|---|
| Scope added to a home inspection | $100 to $250 |
| Stand-alone scope by an inspector | $150 to $350 |
| Plumber camera inspection | $150 to $500 |
| Locating and depth marking | Add $50 to $150 |
| No cleanout (toilet pull or roof vent access) | Add $75 to $200 or more |
| Spot repair | $1,100 to $2,800 |
| Pipe lining | $4,500 to $12,000 |
| Pipe bursting | $5,500 to $13,500 |
| Full trenched replacement | $7,500 to $18,000 or more |
These are 2026 national estimates from Inspect and Test (scopes) and AlertPlumber (repairs). Both also earn from referrals, so get local quotes. Standard homeowners policies typically exclude lateral failure as wear and tear. A sewer backup endorsement, about $40 to $120 a year, generally covers resulting water damage but not the pipe.
How to choose a sewer line inspection company
- Consider an inspector who doesn't do repairs, for an independent read.
- Confirm you'll get the full video with distance markers.
- Ask if the scope will reach the city main.
- Check that any repair contractor pulls a permit. Sewer lateral work generally needs one, and someone must call 811 before digging.
Questions to ask during a sewer line inspection
- What's the pipe made of, and does it change along the way?
- How far from the house is each problem?
- Did you reach the main? If not, why?
- Is this a cleaning job, a spot repair or a replacement?
- Would lining work here? It suits cracks and root damage but not significant sags.
Sewer scope red flags
- No video, only a verbal summary.
- Pressure to replace the whole line from the same company that ran the camera. Get a second opinion based on the video.
- A scope that stopped short of the main with no explanation.
- Findings with no distance markers, which make accurate quotes hard.
- A clean report on a line jetted just before the inspection, which can temporarily hide roots.
Call a plumber promptly for sewage backing into floor drains or showers, a strong sewer smell, or a sinkhole over the line.
How to get the most from a sewer camera inspection
- Find the cleanout
Look for a capped pipe in the basement, crawl space or yard. If there isn't one, tell the company when you book, since access costs more.
- Book the scope
Ask for recorded video, a written summary and pipe material noted.
- Watch it live
Stand with the operator and have them narrate what you're seeing.
- Save the file
Keep the video and report with your home records so a future scope can be compared.
- Mark trouble spots
If needed, pay for locating so the depth and position are marked in the yard.
- Get two repair quotes
Send the same video to both companies, and ask each to name the method.
- Check your insurance
Ask your agent about a sewer backup endorsement and what it leaves out.
Who is responsible for the sewer line? More answers
Who is responsible for the sewer line from the house to the street?
Usually the homeowner, though the exact boundary depends on the city. It may end at the property line or at the main. Confirm with your city or sewer utility.
Is a sewer scope worth it when buying a house?
It's a small cost compared with the repair prices above, and a standard home inspection doesn't normally include it. Older homes and lots with mature trees are the obvious cases.
Does homeowners insurance cover a broken sewer line?
Typically not when the cause is wear and tear. A sewer backup endorsement may cover resulting water damage, but generally not the repair to the pipe itself. Check your policy.
