Is a sewer line camera inspection worth it before you buy?

What a general inspection does not cover

A standard home inspection is visual and non-invasive. The inspector looks at what can be seen without dismantling anything, which by definition excludes a clay or cast iron pipe buried three to six feet under the front garden. The sewer lateral, the privately owned run from the house to the public main, is almost always outside the scope of that report, and in most jurisdictions it is the homeowner's responsibility all the way to the main, sometimes including the portion under the street.

That combination, invisible plus privately owned plus expensive, is what makes it worth a separate look. Very few other defects in a house have all three properties at once.

What the camera actually finds

Root intrusion is the most common finding. Roots enter at joints in clay or at cracks in cast iron, then grow into a mass that catches solids. Early root intrusion is a maintenance item cleared mechanically. Advanced root intrusion accompanied by joint separation is not.

Bellies, where a section has settled into a dip that holds water, are the second. A shallow belly may run for decades with occasional cleaning. A deep one collects solids every time and becomes a recurring bill.

Then there is material. Clay is brittle and jointed. Cast iron corrodes from the inside and scales. Orangeburg, a bituminized fibre pipe installed in the mid twentieth century, deforms into an oval and fails; finding Orangeburg on a scope is close to a guaranteed replacement in the near future. Modern plastic is generally fine unless it was crushed during backfill.

Finally, the camera finds offsets, cracks, previous point repairs, and whether there is an accessible cleanout at all, which matters more than people expect because a lateral with no cleanout is expensive to service before anyone even looks at the pipe.

How to buy the inspection well

Insist on a recorded video and a written report, not a verbal summary at the kerb. You need something a seller, an agent, or a repair contractor can look at.

Ask for the defect to be located and marked on the surface with a depth. A finding described as fifty feet from the cleanout is not actionable. A finding located under the driveway at four feet is, because it tells you what the repair involves.

Be aware of the obvious conflict: the same firm that scopes the line often sells the repair. That is not disqualifying, since the people with cameras are the people with excavators, but it is a reason to get a second opinion on any finding that leads to a large recommendation, and to prefer a firm willing to hand you the raw video.

Where the line is fully blocked, the camera cannot pass and cannot see. In that case the sequence is to clear the line first and then scope it, and a report produced without a full pass to the main is incomplete.

What to do with the result

A clean scope on a fifty-year-old house is genuine peace of mind and is worth what it cost even when it finds nothing.

A finding is a negotiation, not automatically a walk-away. Repairs range from a spot repair on a single joint, through trenchless lining or pipe bursting where conditions allow, to a full open-cut replacement. Which one applies depends on the material, the depth, the length, and what is on the surface above it. Get a scoped repair quote before deciding what the finding is worth in the price.

The one finding that should genuinely slow you down is a lateral that runs under a structure, a mature protected tree, or a neighbouring property, because access is what makes those repairs expensive rather than the pipe itself.
