Should You Get a Sewer Scope with Your Home Inspection?

When you're buying a home, especially an older one, you're likely focused on the big-ticket items: the roof, foundation, HVAC system, or electrical. But there's one crucial system that’s out of sight — and often overlooked — until it becomes a costly problem: the main sewer line.

That’s where a sewer scope inspection comes in.

What Is a Sewer Scope Inspection?

A sewer scope inspection involves sending a specialized camera into the home’s main sewer line to check for issues like clogs, cracks, tree root intrusion, and pipe collapse. The process is quick, non-invasive, and provides video footage of the condition of the underground piping that carries waste from the home to the municipal sewer or septic system.

When Is It Necessary?

While a sewer scope isn’t always included in a standard home inspection, it’s highly recommended in certain situations:

• Older Homes (Built Before the 1980s): Many older homes used clay or cast iron piping that degrades or collapses over time.

• Large Trees Near the Home: Roots are one of the most common causes of sewer line damage.

• Homes That Have Sat Vacant: Lack of water flow can cause debris buildup or dried-out seals.

• Previous Drain or Plumbing Issues: Frequent backups, slow drains, or bad odors may signal a bigger problem.

• Flipped or Renovated Homes: Renovations sometimes overlook or ignore outdated sewer systems.
  

  

What Can a Sewer Scope Reveal?

A sewer scope can identify issues before they become emergencies. Common findings include:

• Tree Root Intrusion: Roots can break through joints and clog pipes.

• Pipe Cracks or Collapses: Often caused by age, shifting soil, or poor installation.

• Bellied Pipes: A sag in the line where waste and water collect, leading to backups.

• Grease or Debris Buildup: Slows drainage and can lead to blockages.

• Illegal or Poor Repairs: Past DIY fixes or incorrect materials.

  
  

Why It Matters

Replacing or repairing a sewer line can cost thousands of dollars — often $5,000 to $25,000 or more. Catching a hidden issue early gives you the chance to negotiate repairs or price reductions before closing, or at least be aware of what you’re buying into.

For the relatively low cost of a sewer scope (especially compared to the potential repair bill), it’s one of the smartest add-ons you can choose during a home inspection particularly if your new home is more than a few decades old or has big trees nearby.
