Pre-buy sewer camera inspection — the one check buyers skip
Standard general home inspections do not include a sewer scope. On a 1920s–1970s South Bay home, this is the single most financially consequential inspection you can add. A failing sewer lateral costs $8,000–$18,000 to replace (see our trenchless sewer lining cost guide). A camera inspection runs $150–$350. The math is obvious.
Common pre-buy camera findings in National City, Chula Vista and greater San Diego:
- Orangeburg lateral — tar-impregnated wood-fiber pipe installed through the 1970s that deforms into an oval and collapses. If the camera shows an oval-shaped pipe, expect a replacement quote. See what Orangeburg pipe is.
- Clay joints with root intrusion — common on 1940s–60s construction with mature trees. Mild cases line fine; severe cases need pipe burst.
- Cast-iron channeling — the bottom of the pipe has corroded through. Walls that remain are thin.
- Bellies — a section has sagged below grade and waste pools in it. Chronic clogs.
A pre-buy camera finding is a legitimate negotiation lever — buyers typically ask the seller for a credit or a repair before closing. We provide the footage specifically so you can share it with your agent.
Recurring-clog diagnosis — when to stop clearing and start looking
If a plumber snaked your main line and three months later it is backing up again, the clog never really went away. The cable punched through — the pipe is still obstructed. A camera tells you *why*:
- Roots. How dense, which joint, do we need to cut annually or line permanently?
- Belly. Is this a slow-collapse Orangeburg situation or a shallow sag we can live with?
- Collapse. Is the pipe actually missing a section? Replacement is the only answer.
- City-side block. Is this on your side of the tap or the city's? Who pays?
The camera settles the question. Then the quote is based on evidence.
Insurance-driven camera inspections
Standard California homeowners insurance does not cover sewer lateral replacement unless you have a Service Line endorsement (see our California sewer insurance guide). When filing a sewer-backup claim, the adjuster typically asks for:
- Camera footage of the lateral
- A written cause-of-loss statement
- Marked location of the failure
- Our C-36 license and insurance information
We provide all four as part of a documented inspection — adjusters accept it.
What the camera cannot do
A sewer camera is not a leak-detection tool for pressurized supply lines (water pipes). For hidden supply-side leaks we use acoustic and thermal leak detection, which is a different diagnostic.
A camera also cannot see through standing water. If your line is actively backed up, we clear it first (drain cleaning or sewer backup response) and then camera afterward to find the root cause.
