Buying a home is one of the biggest investments you’ll ever make. While most buyers understand the importance of a standard home inspection, there’s one area often overlooked: the sewer line. A sewer scope inspection is a simple, affordable step that can save you from thousands of dollars in surprise repairs.
What Is a Sewer Scope Inspection?
A sewer scope inspection uses a specialized camera to examine the inside of your home’s sewer line. The inspector feeds the camera through a cleanout or access point, and it travels through the pipes all the way to the city connection or septic tank.
This gives a clear video of the pipe’s condition — showing cracks, blockages, root intrusions, or even collapsed sections.
For a deeper look at how frequent sewer line problems like blockages, leaks, or line breaks can affect homes and safety, check out the EPA’s Sanitary Sewer Overflows (SSOs) page.
Why It Matters for Homebuyers
The sewer line is buried underground, which means you can’t see its condition during a walk-through or traditional home inspection. Unfortunately, when problems exist, repairs can cost anywhere from $3,000 to $20,000+ depending on the damage.
Getting a sewer scope inspection before closing allows you to:
- Identify hidden issues before you buy.
- Negotiate repairs or replacements with the seller.
- Avoid moving in only to face a costly sewer emergency.
Common Problems Found in Sewer Scope Inspections
- Tree root intrusion – roots naturally seek water and can break into pipes.
- Cracked or collapsed lines – common in older clay or cast iron pipes.
- Blockages – grease buildup, foreign objects, or broken pipe sections.
- Outdated materials – Orangeburg, clay, or corroded cast iron often need replacement.
Who Should Get One?
Every buyer should consider a sewer scope, but it’s especially important if:
- The home was built before 1980.
- Large trees are near the sewer line.
- You notice slow drains, gurgling toilets, or foul odors.
- The home has a history of sewer backups.
Bottom Line
A sewer scope inspection is a small investment that provides peace of mind and protects you from unexpected, expensive repairs. If you’re buying a home in New Jersey, scheduling one is one of the smartest moves you can make before closing.
