Of all the sewer costs a homeowner encounters, this is the smallest and the one most worth paying. It is also where the cheapest option is most often a false economy, because an inspection you do not receive footage from has not really told you anything.
What the market data shows
Published 2026 figures put Maryland sewer camera inspections at roughly $250 to $500. Nationally, most homeowners with a straightforward residential scope land somewhere in the $175 to $450 range.
Montgomery County specifically reads higher. HomeAdvisor’s data for Potomac shows a typical range of roughly $280 to $1,150 — a spread that reflects exactly the local conditions we see: older properties, deeper connections and laterals where the cleanout was buried during landscaping decades ago.
Add-ons such as recorded footage, emergency scheduling or combining the inspection with jetting are commonly reported in the $150 to $800 band depending on scope.
What moves the price
- Whether there is an accessible cleanout — the big one. Without it, access has to be created first.
- Run length, and how many branches need a separate pass.
- Whether the line has to be cleared before the camera can advance past a blockage.
- Whether you need a formal written report, for example for a real estate transaction.
- Depth and access, which in this county vary far more than people expect.
When it costs nothing
Camera inspection is included with our sewer line services — the diagnostic pass before the work and the verification pass afterwards. If you proceed with a repair, the inspection that informed the quote is part of the job.
It can also be booked entirely on its own with no obligation. Plenty of people book one purely to get a second opinion on somebody else’s replacement quote, and that is a completely reasonable use of it.
What a proper inspection includes
The word "inspection" is doing a lot of work in some quotes. At minimum, what you pay for should get you:
- A full-length run from cleanout to the public main — not just the first few feet
- Surface locating and depth marking of anything found
- The recorded footage, handed to you to keep
- A written summary in plain language rather than trade shorthand
- A straight answer on whether anything actually needs doing
The value in proportion
Put this number next to the decisions it informs. An inspection is a small fraction of a spot repair, a smaller fraction of a lining job, and a rounding error against a full replacement that published data puts in five figures.
It is the difference between a scaled cast iron line being descaled and the same line being replaced unnecessarily. Before buying an older home, it is the difference between negotiating a lateral repair into the purchase price and inheriting it. Spending it is almost always the cheap decision.
Before you buy a house
A standard home inspection does not cover the sewer lateral. Buyers routinely assume otherwise, and in a county where a great deal of the housing stock predates 1980, that assumption is expensive.
Booking a scope during the inspection contingency keeps any finding negotiable. Discovering the same defect after settlement means paying for the whole thing yourself.
