If you are buying an older home in the Santa Clarita Valley, book a sewer camera inspection during escrow, because a standard home inspection does not look inside the sewer line and the line becomes your responsibility the day you close. The inspection takes an hour or two, and it is the only way to know whether the pipe under the yard is sound, root-filled or broken before the house is yours.
It matters most on homes with mature trees and original clay or cast iron pipe, which describes a lot of Newhall, Canyon Country and older Saugus streets.
Why a home inspection is not enough
A general home inspector runs the taps, flushes the toilets and watches the water drain. That tells you the drains work today. It tells you nothing about the pipe outside the foundation, where most sewer failures happen.
A partly blocked or cracked line can drain perfectly well during a 20-minute inspection, especially in a house that has been empty for weeks. The problems show up after a family moves in and the line carries a full household's water every day.
The buyer inherits the whole lateral
The pipe that carries waste from the house to the public sewer is called the lateral, and in Los Angeles County it belongs to the property, not to the county. County Public Works states that sewer laterals are entirely owned by the property owner they serve, and that the owner is responsible for the entire length, including the portion under the street and street landscaping. County Code 20.24.080 requires the owner to keep it in a safe and sanitary condition (LA County Public Works, Sewer Maintenance customer information).
So a cracked lateral under the street is not the city's problem once you own the house. It is yours, and the cheapest moment to find it is before you sign.
What the camera shows
We feed a camera through the cleanout and run it the length of the lateral, recording as it goes. The footage shows:
- Roots pushing in at pipe joints, the most common find under older lawns with mature trees
- Cracks and breaks in clay or cast iron
- Offset joints, where one section has shifted out of line with the next
- Sags or bellies, low spots where water and waste sit instead of flowing
- Scale and corrosion inside old cast iron, which narrows the pipe
- Pipe material and changes in it, such as a newer plastic repair spliced into an old clay line
The camera signal can be traced from the surface, so any fault is marked on the ground with its distance from the house and its depth. That turns "there may be a problem" into a location and a size of job.
Which homes need it most
Not every house needs one. A home in a newer Valencia or Stevenson Ranch tract with plastic sewer pipe is a lower risk. The case for a camera gets stronger with each of these:
- The home was built before the 1980s, when clay and cast iron laterals were common
- There are large trees between the house and the street
- The sellers mention past drain clearing, or there is a cleanout that looks well used
- Floor drains, a lower toilet or a tub drain slowly or gurgle
- The house has been vacant, so recent use tells you nothing
What it costs, and what drives the price
We do not publish a flat price, because the job varies more than you might expect. What moves it:
- Access. A clear, accessible cleanout is quick. No cleanout, or one buried under a patio, means removing a toilet or creating access first.
- Length of the line. A deep lot with the house set far back means more pipe to run.
- Whether the line needs clearing first. A camera cannot see through a blockage, so a badly blocked line has to be opened before it can be inspected.
- Locating. Marking the depth and position of a fault on the ground adds a little time, and it is what makes the footage useful for a repair quote.
We quote it in writing before we start. Set against the cost of a sewer repair you did not see coming, it is a small line in a home purchase. Our sewer line repair cost guide explains what the repairs themselves involve.
How to use the results in escrow
Ask for a copy of the footage and the written findings, then share them with your agent. Depending on what the camera finds, buyers commonly:
- Proceed as normal when the line is clean, with peace of mind and a baseline for later
- Ask for a repair or a credit when there is root intrusion, a break or a sag, using a written repair quote as the basis
- Plan for maintenance when the line is old but sound, for example periodic root clearing
Book the inspection early in the contingency period. If the footage shows a problem, you want time to get a repair quote before your deadline, not the day before it.
