Part 1 of 4

Why a seller cares

A camera down the sewer line finds roots, cracks and bellies that no general inspection can see, and repairs run into the thousands. Buyers of older homes order one routinely, and a finding is usually a seller cost.

Part 2 of 4

A simple example

The scope on your 1962 house finds root intrusion twenty feet out and a small offset joint. A plumber quotes $4,800 to repair the section.

Sewer scope: a simple example
What the camera findsWhat tends to follow
Clear lineNothing; the item closes
Roots, no damageA hydro-jet cleaning, a few hundred dollars
A cracked or collapsed sectionA repair in the thousands, usually negotiated as a credit

The sewer line is out of sight and expensive, which is exactly why buyers look.

Part 3 of 4

What people get wrong

That the city owns the line. The homeowner usually owns it to the main, and its repair is the homeowner's cost.
