How Much Does a Manhole Inspection Cost?
Few companies publish a flat price. Here is what goes into the number so you can compare quotes with confidence.
The Short Answer on Manhole Inspection Prices
Few companies publish a flat price for a manhole inspection. The closest published benchmark is a sewer camera inspection, which national data puts at $125 to $500. A manhole inspection adds structural checks, gas testing and a report on top of that camera work.
Manhole pricing is rarely published as a flat rate because no two structures are alike. Depth, access and what the owner needs from the report all change the quote.
This guide explains what you pay for and how to compare quotes. For service in South Jersey, see our manhole inspection service.
What a Manhole Inspection Covers
A manhole inspection checks the structure itself and the pipes connected to it. The goal is to catch cracks, leaks and blockages before they cause a backup.
The structure
The inspector looks at the walls, the frame and cover, the steps or ladder, and the seals where pipes enter. Cracks, loose bricks and failing joints all get noted.
The connected lines
A camera travels into the pipes that run in and out of the manhole. It shows clogs, root intrusion, sediment and breaks you cannot see from the top.
Gas and safety checks
Sewer structures can hold harmful gases. At The Sewer Kings, inspections include testing for gases like methane and hydrogen sulfide.
The standard behind it
For larger systems, NASSCO’s Manhole Assessment and Certification Program, known as MACP, sets a common way to rate manhole condition. That lets results be compared over time.
Flow and sediment
The inspector also looks at how water moves through the structure. Standing water, heavy sediment or debris at the bottom can point to a blockage downstream.
The cover and frame
A loose, cracked or sunken cover is a safety risk for anyone walking or driving over it. The inspector checks that the frame sits level and the cover seats firmly.
What Changes the Price of a Manhole Inspection
Most of the cost comes down to time, equipment and paperwork. These are the factors that move a quote up or down.
Camera work
A camera run adds cost but shows what a visual check cannot. HomeGuide’s 2026 camera inspection data puts a sewer camera inspection at $125 to $500, with a national average of $280.
Inspection level
NASSCO’s program has two levels. Level 1 is basic, and Level 2 is more detailed. GPRS explains that a Level 1 inspection takes about 15 to 30 minutes per manhole, while a Level 2 with detailed measurements can take 30 to 45 minutes.
Number of manholes
Setup is shared across structures on the same site, so ask for a per manhole price when you have more than one.
Depth and access
A deep manhole, a buried or paved over cover, or one in a busy lot takes more time and safety setup.
Report detail
A quick condition note costs less than a full written report with photos and video for an insurer, buyer or township.
Findings that need follow up
The inspection itself is one price. If the camera finds roots, a crack or a blockage, the repair is a separate quote. Ask how the company handles that before you book.
Emergency timing
An inspection during an active backup takes more setup and often comes at a higher rate than one booked ahead of time.
Manhole Inspections From The Sewer Kings
The Sewer Kings inspect manholes for commercial property managers, landlords and homeowners with private manholes across Burlington, Camden, Gloucester and Ocean counties. Most inspections finish in 1 to 2 hours.
We check the walls, ladder and frame, run a camera through the connected drain lines, and test for sewer gases. Every crack, root intrusion or sediment buildup gets documented.
Older areas matter here. Evesham’s older neighborhoods near Route 73 have clay pipes that crack over time, and manholes often connect a mix of PVC, cast iron and clay. Our cameras show which sections need repair without guessing.
We also offer emergency checks for active backups. Anthony and Mark Papaneri started out on their father’s water and sewer projects, and the crew still answers the phone 24/7.
Every finding comes with clear notes on what we saw and where. If something needs repair, you will know the location and what kind of fix to expect before any work is quoted.
We also look at how the manhole sits in the ground around it. A sunken area around the frame can mean soil is washing into the structure, which is a problem worth catching early.
For property managers, we can inspect several structures in one visit. That keeps setup time down and gives you one clear record for the whole site.
How to Compare Manhole Inspection Quotes
Ask what is included. A fair quote names the visual check, the camera work, gas testing and the kind of report you will get.
Ask how many manholes and connected lines are covered. A low price for one structure is not the same as a price for the whole property.
Ask for footage. Video of the connected lines is the proof that the inspection happened and shows exactly where any repair is needed.
Ask about timing too. Booking an inspection before a known issue becomes a backup is almost always cheaper than calling in the middle of one.
If you manage more than one property, ask whether a regular inspection schedule can be set up. Tracking the same manholes over time makes changes easier to spot.
Keep every report on file. When the next inspection comes, comparing old and new footage shows exactly what has changed.

Manhole Inspection Cost: Common Questions
How long does a manhole inspection take?
A basic structural check can take well under an hour per manhole. With camera work on the connected lines and gas testing, most inspections run 1 to 2 hours. Sites with several manholes take longer.
How often should a manhole be inspected?
It depends on the property and how hard the system works. Commercial sites and structures with a history of backups benefit from regular checks. Inspecting after a backup or heavy rain can catch damage early.
