A sewer inspection sends a waterproof camera through the pipe between your house and the street, and records what it sees. It shows roots, cracks, offset joints, sags, scale and blockages that no one can judge from above ground. Licensed plumbers book it as a same-day appointment when available. Take note of any symptoms before the visit, such as slow drains, gurgling and sewer odors, so the plumber knows where to look.
Questions people ask before booking a sewer camera inspection
Most residential lines take under an hour once the camera has access through a cleanout. A long run, a line that needs cleaning first, or a locate afterward adds time. The plumber tells you the expected scope and gives a clear price before work starts.
Ask for one when you book. A recording and a short written note of what was found, with distances from the entry point, are what a buyer, seller, insurer or repair contractor will want. If a plumber will not provide either, ask why.
A camera shows the inside surface. It cannot measure how strong the pipe wall is, and it cannot see past a full blockage or a collapse. It also cannot tell you whether a stoppage sits in the public main. For that, ask Milton Water and Sewer.
Sometimes. Heavy grease, scale or water sitting in the pipe blocks the lens. The plumber may run a cable or a gentle flush first. That is a separate step, and you should know before the visit whether it is included in the price.
It can show a crack, an open joint, or roots entering at a seam, which often means water is escaping. It cannot prove how much is leaking. If you suspect a pressurized water line is leaking, that is a leak detection question, not a sewer one.
Usually the buyer, during the inspection period. You can ask the seller for access and pay for it yourself. A recording gives you evidence to negotiate on price or repairs. Check your purchase contract for the deadline and ask your attorney about timing.
Yes, when a building has repeated backups or before a purchase. The recording shows whether the pattern comes from tenant habits or pipe damage, and tells you whether cleaning will hold or repair is the better spend.

(617) 752-0573Slow drains, gurgling or a sewer smell, but nothing is clearly broken
When several fixtures drain slowly or the yard smells of sewage, guessing at the cause wastes money. A drain cleaning might not be enough, and an expensive dig might not be needed. A sewer inspection with a camera answers the question first.
Buying an older Milton home? Look at the sewer before closing
The Town of Milton Housing Production Plan reports that about 75 percent of Milton homes were built before 1960, and the median age is 71 years. Pipes from that era may be cast iron, clay or fiber, and they can crack, shift or collapse long before the house shows any sign of trouble. A repair found after closing is yours to pay for.
For that reason, a camera recording during the buyer's inspection period is a sensible step on an older house. If the footage shows damage, you can ask the seller to fix it, lower the price, or walk away. If it shows a sound line, you close with real information.
What the footage can show
| On screen | What it usually means | Typical next step |
|---|---|---|
| Dark, rough, flaking walls | Scale or corrosion in cast iron | Clean, monitor, or line if still round |
| Fine hairlike strands at joints | Roots entering a seam | Cut roots, then repair or line the joint |
| Standing water in a low stretch | A belly where the pipe has sagged | Monitor, or replace that section |
| Joint offset or gap | Pipe sections have shifted | Spot repair |
| Pipe wall missing or oval | Collapse or fiber failure | Replacement |
| Smooth clean wall, steady flow | Healthy line | No action beyond good habits |
A plumber who gives you only a verbal verdict and no recording makes it hard for another contractor to compare.
Questions about sewer inspection? Call a plumber
Licensed plumbers are dispatched day and night, and you hear the price before work starts.
What a locate does
A locate pairs the camera with a transmitter in the camera head. A receiver above ground picks up the signal and shows the depth and the path of the pipe. The plumber marks the spot with paint or a flag.
This matters if a repair needs excavation, because it keeps the trench to the damaged section. Digging still needs a call to Dig Safe at 811, at least 72 business hours before, and the locate does not replace that call.
How the visit goes
Find the cleanout
Most inspections enter through the cleanout. Without one, a toilet may be pulled.Run the camera
The camera moves toward the street while the plumber watches and records.Note distance and depth
Each defect is logged with its distance from the entry and, if located, its depth.Explain the findings
The plumber shows what was found and what, if anything, needs doing.Provide the record
You leave with the recording and notes you need for a buyer, seller or contractor.
What to ask for, and what the camera cannot do
Request a few things when you book:
- A complete recording of the run from the entry point to the street connection.
- A written note listing each defect with its distance from the entry.
- Depth and surface location of any defect that may need digging.
- A plain statement of whether the line is clear to the end or the camera was stopped.
- The pipe material, as seen on the screen.
What affects the price of a sewer inspection
A clear price comes before work starts. These drivers shape it.
Access
A working cleanout is quick. Pulling a toilet to get in takes longer.
Length of the run
A longer line to the street takes more time and cable.
Cleaning first
A heavily coated or blocked line needs clearing so the lens can see.
Locate and report
Marking depth and writing notes add steps beyond a basic look.
Standard homeowners policies usually do not pay for inspection as a maintenance step, and wear or gradual damage is commonly excluded. Policy wording decides, so read it or ask the insurer.
After the inspection
If the line is clean, keep it that way. If it needs work, sewer line repair or sewer line cleaning follows, and we also serve Canton next door.
