Why Every Home Buyer Should Get a Sewer Scope Before Closing

When buying a home, most people focus on inspections for the roof, foundation, and electrical systems. However, one critical inspection that often gets overlooked is a sewer scope inspection. While it may not be the most glamorous part of the home-buying process, it can save you from unexpected and costly repairs down the road.

What Is a Sewer Scope Inspection?

A sewer scope is a specialized inspection where a small camera is inserted into the home's main sewer line to check for any issues, such as blockages, tree root intrusion, cracks, or collapsed pipes. The process is quick, typically taking less than an hour, and can reveal hidden problems that are otherwise impossible to detect during a standard home inspection.

Why Is a Sewer Scope Important?

1. Unseen Damage Can Be Costly

A home's sewer line is underground, meaning problems often go unnoticed until major issues arise. A damaged sewer line can lead to sewage backups, water damage, and even structural issues. Repairing or replacing a sewer line can cost anywhere from $3,000 to $25,000, depending on the severity of the problem.

2. Tree Roots Can Be a Hidden Threat

Many older homes have clay or cast iron pipes, which are especially vulnerable to tree root intrusion. Over time, roots can grow into the pipes, causing blockages or even breaking them apart. A sewer scope inspection can detect early signs of this problem before it leads to a major failure.

3. Older Homes Often Have Aging Sewer Lines

If you're buying a home built before the 1980s, the sewer system may be outdated and prone to deterioration. Many older homes still have Orangeburg pipes, which are made of a paper-based material that collapses over time. Even newer homes can have issues if poor materials or improper installation were used.

4. Newer Homes Aren't Immune to Sewer Problems

Even newly constructed homes can have sewer issues. Construction debris, improper connections, or poorly installed lines can cause blockages or misalignments. A sewer scope can ensure that everything is functioning properly before you finalize the purchase.

5. It Can Be a Negotiation Tool

If a sewer scope reveals issues, you can negotiate with the seller to cover repair costs or lower the purchase price. Many buyers who skip this inspection only discover problems after moving in—when they’re stuck footing the bill.

How Much Does a Sewer Scope Cost?

A sewer scope inspection typically costs between $200 and $500—a small price to pay compared to the potential thousands you could spend on repairs. It’s a worthwhile investment for peace of mind.

The Bottom Line

A home’s sewer line is one of the most critical (and expensive) components of a property. Without a sewer scope inspection, you could be buying a house with a major plumbing disaster waiting to happen. Before closing on your home, make sure to schedule a sewer scope—your future self (and your wallet) will thank you!
