Why a Sewer Scope Inspection Matters When Buying a Home in West Michigan

Tony Hernandez October 30, 2026

When buying a home in Grand Rapids, Grandville, or anywhere throughout West Michigan, most buyers understand the importance of having a professional home inspection. They want to know about the roof, foundation, furnace, electrical system, and plumbing.

But there's one important part of the home that buyers sometimes overlook: the underground sewer line.

It's something you can't see during a typical home showing, and problems with it can potentially cost thousands of dollars to repair.

As a Realtor serving West Michigan, I've seen firsthand why a sewer scope inspection can be one of the most valuable additional inspections a homebuyer chooses.

What Is a Sewer Scope Inspection?

A sewer scope inspection involves inserting a specialized camera into a home's sewer line to examine the condition of the underground piping.

This allows an inspector to identify potential problems such as tree roots growing into the pipes, blockages, cracks, deteriorating materials, or sections of pipe that have shifted or become damaged.

Unlike a standard home inspection, which generally focuses on the visible and accessible components of a property, a sewer scope provides a closer look at something hidden underground.

And just because the sinks drain properly and the toilets flush doesn't necessarily mean the sewer line is in good condition.

Three of My Buyers Discovered Sewer Problems in the Past Year

Over the past year, I've had three different buyers whose sewer scope inspections revealed clogging inside the sewer lines.

In all three situations, additional drain-cleaning work was necessary to clear the pipes, followed by further inspection to evaluate their condition.

These weren't necessarily problems anyone would have noticed while walking through the homes.

The plumbing appeared to be functioning, but the camera inspections told a different story.

That's why I believe these inspections are so important.

A sewer scope can uncover problems before buyers take ownership of a property, giving them an opportunity to investigate the issue and determine what needs to happen next.

A $4,700 Sewer Repair Discovered in Grand Rapids

One particular transaction really demonstrated the value of having a sewer scope performed.

During the inspection process for a home in Grand Rapids, a sewer scope revealed an issue with the sewer system that required approximately $4,700 in repairs.

Fortunately, in this particular case, the City of Grand Rapids covered the cost of the repair.

That's not something buyers should automatically expect. Responsibility for sewer repairs can vary depending on the location of the problem, the circumstances, and the municipality's policies.

But imagine if that inspection hadn't been performed.

The buyer might have purchased the home without knowing there was an issue underground.

Instead, the problem was identified during the inspection process, allowing it to be addressed before it became an unexpected expense.

That's a perfect example of why spending a little extra money on an inspection can potentially save a buyer thousands of dollars.

Are Sewer Scope Inspections Only Necessary for Older Homes?

Older homes throughout Grand Rapids and West Michigan can be particularly susceptible to sewer line problems.

Some have aging clay or cast-iron sewer pipes that can deteriorate over time. Tree roots can also enter pipes through cracks or joints, eventually restricting the flow of wastewater.

However, newer homes aren't necessarily immune.

Construction debris, improper installation, damaged piping, and other issues can sometimes affect newer sewer systems as well.

While the age of a home is certainly something to consider, I wouldn't make that the only deciding factor when determining whether to have a sewer scope inspection.

How Much Does a Sewer Scope Inspection Cost?

A sewer scope inspection generally costs a few hundred dollars, although the exact price depends on the inspection company, property, and accessibility of the sewer line.

It's important to understand that a sewer scope is typically an additional service and isn't automatically included in a standard home inspection.

When you consider that significant sewer line repairs can cost thousands of dollars, the additional expense may be well worth it.

Of course, no inspection can guarantee that problems won't develop in the future. However, a sewer scope can provide valuable information about the condition of the line at the time of inspection.

What Happens if the Sewer Scope Finds a Problem?

Discovering a sewer issue doesn't necessarily mean you should walk away from purchasing the home.

It means you have more information to work with.

Depending on the findings, buyers may want to have a licensed plumber evaluate the issue, obtain repair estimates, or request additional inspections.

In some situations, the problem may be resolved with a relatively straightforward drain cleaning.

In others, more extensive repairs may be necessary.

Depending on the terms of the purchase agreement and the inspection contingency, buyers may also have an opportunity to negotiate repairs or other solutions with the seller.

The important thing is discovering the problem before closing, when there may still be an opportunity to address it.

My Advice to West Michigan Homebuyers

I've helped buyers purchase homes throughout Grand Rapids, Grandville, and communities across West Michigan, and one thing I've learned is that a thorough inspection process can make a tremendous difference.

A home can look beautiful on the surface while still having issues that aren't immediately visible.

That's why I encourage buyers to consider the additional inspections available to them, including a sewer scope.

After having three buyers discover sewer line problems in the past year, including one situation involving a $4,700 repair, I've seen the value of these inspections firsthand.

Buying a home is a major investment. Understanding what you're purchasing, including what's happening underground, can help you make a more informed decision and potentially avoid expensive surprises.
