A sewer scope is one of the most valuable add-on inspections you can get when buying a home in the Portland metro area, yet many buyers have never heard of it. Here is a plain explanation of what it is and why it matters.
What Is a Sewer Scope?
A sewer scope inspection involves running a small waterproof camera on a flexible cable down through a cleanout or drain opening in your home and all the way to the city sewer connection or septic tank. The camera sends live video back to a monitor so the inspector can see the inside of the pipe in real time. The whole process takes about 30 to 60 minutes. You get a recording of the video and a written summary of what was found.
What Problems Can a Sewer Scope Find?
Tree root intrusion is one of the most common findings in older neighborhoods where mature trees are present. Roots from trees and shrubs naturally seek out moisture, find their way into tiny cracks in sewer pipes, and then grow inside, eventually causing blockages or pipe damage.
Pipe deterioration from older clay tile or cast iron pipes can cause cracks, shifting, or collapse. Even a partial collapse creates a low spot where waste collects and causes repeated clogs and eventually sewage backup. Off-grade pipe means the pipe has shifted so it no longer drains properly, creating a dip or belly in the line. Grease buildup and breakage near the street from vehicle weight or ground movement are also common findings.
Why Is This Especially Important in Portland?
Portland has a large number of homes built before 1960, many with original clay tile sewer lines. Clay tile has a long life but eventually fails. Many of Portland’s neighborhoods also have mature trees with aggressive root systems. It is not uncommon to find root intrusion even in homes with no large trees on the property itself.
What Does Sewer Repair Cost?
A simple cleaning can cost a few hundred dollars. A spot repair of a specific section can run $2,000 to $5,000. A full sewer line replacement from the house to the street typically costs $8,000 to $20,000 depending on depth, distance, and whether trenching or trenchless methods are used. Knowing about this before you buy gives you real negotiating power.
How Much Does a Sewer Scope Cost?
