Why I Always Recommend a Sewer Scope When Buying a Home

When buyers think about inspections, they usually picture the roof, HVAC, or foundation. The sewer line rarely comes to mind. In my experience as a Tucson real estate agent, that underground pipe can become one of the most expensive surprises a buyer faces.

That is why I always recommend getting a sewer scope during the inspection period.

It is a small add-on that can prevent a very big problem later.

What Is a Sewer Scope?

A sewer scope is a camera inspection of the main sewer line that runs from the house to the city connection. An inspector inserts a small waterproof camera into the line and records the condition of the pipe.

The camera travels through the pipe and shows what is happening underground. You can see cracks, buildup, roots, or other issues that would otherwise stay hidden.

Most general home inspections do not include this service automatically. Many inspection companies offer it as an optional add-on.

In Tucson, that add-on usually costs around $75 when bundled with a home inspection.

Why a Sewer Scope Is Important

Sewer lines stay out of sight, so many buyers assume they work fine. Unfortunately, that is not always the case.

I have seen deals fall apart because of sewer problems. Repairs can become very expensive if the main line fails.

In many cases, a full sewer line replacement can cost $10,000 or more (sometimes much more!).

A sewer scope gives buyers information before closing instead of after moving in.

Sewer Scope Issues in New Construction Homes

Many people assume new construction homes do not need a sewer scope. I still recommend one every single time.

New homes can have sewer issues too. There have been cases where sewer systems were not connected at all. That means sewage ran directly under the home. I have also seen warped pipes, construction debris inside the line, and even cement blocking sections of pipe.

Builders move quickly, and mistakes happen. A quick camera inspection can catch those problems early.

Sewer Scope Issues in Older Homes

Older homes can develop different types of sewer problems over time.

Tree roots often grow into pipes while searching for water. Mineral buildup can slowly restrict the flow inside the line.

Pipes can also crack, shift, or collapse as the ground settles.

A sewer scope makes these problems visible before they become a major repair.

Two Ways to Get a Sewer Scope

Buyers usually have two options for getting a sewer scope.

The first option is adding it through the home inspection company. Many inspectors offer the service for about $75 as an additional inspection item.

Inspectors typically provide the video footage but not repair quotes.

If the scope shows a problem, you can send that video to a plumber for an estimate.

The second option is hiring a plumber directly. In the Tucson area, plumbers usually charge $100 to $175 for a sewer scope inspection.

This option costs more, but plumbers can often provide repair quotes on the spot if they find a problem.

My Advice as a Tucson Realtor

After years in real estate, I have learned one simple rule: Always get a sewer scope.

It does not matter if the home is brand new or fifty years old. That small inspection can reveal hidden issues that might otherwise cost thousands of dollars after closing.

When buyers ask me which inspections are worth the extra cost, this one always sits near the top of my list.

Spending $75 now can protect you from a five figure repair later. That is an easy decision in my book.
