Sewer Scope Inspections: What Every Homebuyer Needs to Know
When buying a home, what you can’t see can hurt you. And few systems are more overlooked than the main sewer line. While most buyers focus on kitchens, roofs, and cosmetic finishes, the truth is that thousands of dollars in damage often lurk underground. Sewer Scopes save families thousands of dollars daily across the USA.
A sewer line defect can lead to raw sewage backing up into the home, exposure to dangerous gases, ground contamination, and even structural instability due to sinkholes. That’s why every home inspection should include a sewer scope — and why it should be done by a Certified Full Spectrum Inspector from FSIA.PRO.
What Is a Sewer Scope Inspection?
A sewer scope inspection is the process of inserting a specialized waterproof camera into a home’s main sewer line to visually inspect its condition from the inside. This high-resolution camera feeds real-time video back to the inspector, who is trained to identify various types of defects, blockages, and system failures that may not be visible from above ground.
While a standard home inspector may not perform this service, Certified Full Spectrum Inspectors are trained and equipped to do so. And they know exactly what to look for.
Common Defects Found in Sewer Lines &Why Everyone Needs Sewer Scopes
Sewer lines can deteriorate, shift, and break down over time. Some of the most common defects we discover during sewer scopes include:
-
Offsets – Pipe sections have shifted and no longer align properly, causing flow restrictions and waste buildup.
-
Bellies (Sags) – Low spots where water and waste accumulate, creating stagnant pools and blockages.
-
Cracks and Holes – These allow sewage to leak into the surrounding soil and open the line to root intrusion, erosion, or collapse.
-
Root Intrusion – Tree roots find their way into sewer pipes and expand, eventually cracking the pipe and causing backups.
-
Grease, Scale, and Buildup – Years of use can cause narrowing of the pipe, reducing flow and increasing the risk of clogs.
-
Foreign Objects – Non-biodegradable materials, construction debris, or improperly flushed items can block or damage the line.
Without a camera, none of these defects are visible — until the damage is done.
Health Hazards of Sewer Failures
When sewer lines fail, the consequences extend beyond inconvenience or plumbing bills. A backup or leak can introduce harmful substances into the home, including:
-
Airborne bacteria
-
Methane gas
-
Sulfur and sulfur hydrochloride gases
These contaminants can cause respiratory irritation, headaches, nausea, fatigue, and even long-term health issues with prolonged exposure.
In addition, when sewage floods the interior of a home, it often soaks into rugs, furniture, bedding, and clothing. Many of these items cannot be safely salvaged and must be professionally sanitized or discarded entirely.
Property Damage and Outdoor Hazards
Outdoors, leaks and breaks in the line can saturate the soil, leading to contaminated ground where children and pets play. Worse still, if the defect undermines the surrounding earth, it can cause sinkholes to form. These are not only dangerous for people, but can threaten the foundation of the home itself.
In many cases, homeowners are completely unaware of these risks until they face a full-blown backup or discover severe structural issues.
The High Cost of Sewer Repairs
According to national data, the average cost to repair a sewer line is approximately $7,500. In cases where a full replacement is needed, the cost can easily rise to $15,000 to $30,000, especially if the line runs beneath driveways, mature trees, or other major obstructions.
By contrast, the cost of a sewer scope is minimal — and it provides critical insight that can save thousands. It can also serve as a powerful negotiation tool during real estate transactions.
Why FSIA Certified Inspectors Are Different |Trained &Experienced in Providing Sewer Scopes

-
Professionally certified and vetted
-
Trained in sewer scope and camera technology
-
Experienced in identifying and documenting structural and environmental issues
-
Committed to providing science-based evaluations, not surface-level opinions
When you hire a Full Spectrum Inspector, you get a far deeper look into the home’s safety, stability, and long-term livability.
When Should You Get a Sewer Scope?
We recommend sewer scope inspections in the following situations:
-
Before purchasing any home, regardless of age
-
Homes more than 20 years old (pipes naturally degrade)
-
Properties with large trees near the sewer line
-
Homes with recent plumbing issues or slow drains
-
As part of a Full Spectrum Inspection for buyers, sellers, or investors
Skipping this one service could mean walking blindly into a five-figure repair.
