PLUMBING
Why You Should Always Scope the Sewer Before Closing
A standard home inspection covers the interior plumbing — faucets, fixtures, water pressure, and visible pipes. But what about the underground sewer line that carries waste from your home to the city main? That’s where a sewer scope inspection comes in.
What Is a Sewer Scope?
A sewer scope is a video inspection of the main sewer line. A waterproof camera is inserted into a cleanout access point and pushed through the pipe, capturing live video of the interior. The inspector looks for:
- Root intrusion — tree roots are the #1 cause of sewer line problems
- Cracks or breaks — from ground movement, age, or heavy traffic overhead
- Bellied sections — low spots where waste can pool and clog
- Offset joints — misaligned pipe sections from shifting soil
- Grease buildup or blockages — common in older homes
Why It Matters
Sewer line repairs are among the most expensive home repairs you can face. Depending on the extent of damage, costs can range from $3,000 for simple repairs to $15,000 or more for full line replacement, especially if the line runs under a driveway, landscaping, or structure.
The main sewer line is not visible during a standard inspection. Without a scope, you have no idea what condition it’s in — and problems may not show symptoms until the line backs up completely.
Older Homes Need Extra Attention
Homes built before the 1980s often have clay or cast iron sewer lines, which are more prone to cracking and root intrusion than modern PVC pipes. If you’re buying a home that’s 40+ years old, a sewer scope is especially important.
What Does It Cost?
A sewer scope inspection typically runs between $150 and $300. That’s a small price to pay for the peace of mind — and potential negotiating power — it provides. We offer sewer scope as an add-on to any home inspection.
