Do I Need a Sewer Line Inspection Before Selling?

Getting Ready to Sell and Wondering About Your Sewer Line

We recently got a call from a homeowner — let’s call him Jake — who was in the middle of selling his house. He told us he’d already left a message about a sewer line inspection and hadn’t heard back yet, and he was starting to feel the pressure of his August 1st deadline.

Jake said, “I need a sewer line inspection for the purposes of selling a house. And I’ll need a written report for the sale paperwork.” That is something we hear a lot from sellers who are trying to stay ahead of any surprises during escrow.

We walked Jake through what a sewer line inspection involves, why it matters so much during a home sale, and how to get ready so the process is smooth and fast. If you are wondering whether you should do the same before listing your home, this post is for you.

What Is a Sewer Line Inspection, Exactly?

When homeowners call us about “a sewer inspection,” they sometimes picture us just lifting a cleanout cap and having a quick look. In reality, a proper real-estate sewer inspection is a camera inspection of the main sewer line that runs from your house out to the city connection or septic tank.

Here is what we typically do for a home sale inspection:

• Locate access – We find the best entry point (usually an exterior cleanout, sometimes a roof vent or basement access).
• Run a camera – We send a specialized waterproof camera through the line to visually inspect the pipe from the inside.
• Record video and notes – We document the condition, measure the distance to any issues, and note materials and connections.
• Provide a written report – Just like Jake requested, we prepare a written summary that you or your agent can include in the sale paperwork.

This is not a replacement for a general home inspection — it is a deep dive into one of the most expensive systems to repair or replace.

Do You Really Need a Sewer Inspection Before Selling?

In many areas, the answer is increasingly yes — or at least, it is strongly recommended. Some cities or utility districts even require a sewer compliance inspection before a property can change hands.

Even when it is not legally required, there are three big reasons we encourage sellers to do it proactively:

• Avoid last-minute surprises – If a buyer’s inspector finds root intrusions, breaks, or sags in the line, you could suddenly be facing a big credit or repair request under tight escrow timelines.
• Strengthen your negotiating position – Coming to the table with a recent, clear sewer report makes buyers more confident and can reduce back-and-forth over repairs.
• Plan repairs on your terms – If the inspection finds something, you can decide whether to fix it, offer a credit, or adjust the listing price in a calm, planned way instead of in crisis mode.

Jake’s main concern was timing: “Can we get this done and have a report in time for my August 1st deadline?” Because he reached out early, we were able to schedule him with plenty of breathing room. That is what we always recommend — don’t wait until you are already in escrow.

What We Look For During a Home-Sale Sewer Inspection

When we perform a sewer line inspection tied to a home sale, we are focused on the issues most likely to affect a buyer’s decision or a lender’s requirements. Our camera inspections typically look for:

• Root intrusion – Tree roots breaking into joints or cracks.
• Cracks and breaks – Structural damage that could lead to leaks or collapse.
• Bellies or sags – Low spots where waste and water collect, causing frequent clogs.
• Offsets and separations – Sections of pipe that have shifted out of alignment.
• Corrosion or deterioration – Especially in older clay, cast iron, or Orangeburg lines.
• Improper connections – Unpermitted tie-ins or transitions that may not meet code.

We then translate all that technical detail into something a buyer, seller, and agents can easily understand: overall condition, any immediate concerns, and recommended next steps.

How to Prepare Your Home for a Sewer Line Inspection

Jake asked what he needed to do before we came out. Preparing takes just a little effort, but it makes the visit quicker and more efficient. Here is what we usually ask sellers to do:

• Clear access to cleanouts – If you know where your exterior cleanout is, make sure it is not buried under mulch, dirt, or stored items.
• Secure pets – We often need to walk around the yard and near the house; putting pets in a safe space keeps everyone comfortable.
• Know your deadlines – Like Jake’s August 1st target, tell us up front if you have inspection or contingency dates so we can schedule accordingly.
• Gather prior reports – If you had a sewer inspection in the past, we can compare current findings to see what has changed.

In most cases, you do not need to be home the entire time as long as we have access to the cleanout and any required interior areas. Many sellers coordinate access through their real estate agent.

What Happens After the Inspection?

Once we complete the camera work, we typically:

• Review major findings with you (or your agent) in plain language.
• Deliver a written report and, if needed, video files for your records.
• Outline repair options and approximate ranges if we found problems.

Some sellers, like Jake, just want reassurance that the line is in good shape and documentation to show buyers. Others discover issues and need to decide whether to repair before listing, give a credit, or disclose and negotiate. Our goal is to equip you with clear information so you can make those decisions confidently.

Thinking About Selling? Plan Your Sewer Inspection Early

If you are preparing to sell and wondering, “Do I really need a sewer line inspection before I list?” our answer is that it is one of the smartest, most cost-effective steps you can take — especially for older homes, properties with big trees, or any house that has had slow drains or backups in the past.

By scheduling early, making sure you will get a written report for your sale paperwork, and preparing your property for easy access, you can avoid stressful surprises and keep your home sale on track from the first showing to closing day.
