Sewer & Septic Scope Services in Illinois
When purchasing or maintaining a home, some of the most expensive problems are the ones you can’t see, especially those hidden underground. At AA Marshall Home Inspection Services, our Sewer and Septic Scope in Illinois are designed to uncover issues within your home’s wastewater system before they turn into costly repairs.
While a standard home inspection evaluates visible plumbing fixtures and systems, it does not assess the condition of underground sewer lines or septic systems. That’s where our specialized inspection comes in, giving you a complete picture of your property’s health from the inside out.
What Is a Sewer Scope?
A sewer scope involves inserting a high-resolution waterproof camera into the home’s main sewer line through an accessible cleanout. This camera travels through the pipe, providing real-time video footage of the line’s condition.
This process allows our inspectors to identify hidden problems such as:
- Tree root intrusion
- Cracks or fractures in the pipe
- Pipe misalignment or “bellies”
- Corrosion or deterioration
- Grease buildup or blockages
- Collapsed or damaged sections
Without this inspection, these issues can go undetected until they cause serious backups or failures.
What Is a Septic System Inspection?
For properties that rely on septic systems, we perform a detailed evaluation of all major components, including:
- Septic tank condition
- Drain field performance
- Sludge and scum levels
- Pump operation (if applicable)
- Signs of leaks or system failure
Septic systems require regular maintenance, and an inspection helps ensure the system is functioning efficiently and safely.
Why Sewer & Septic Scope Are Essential
Avoid Costly Repairs
Sewer line repairs or replacements can cost thousands of dollars. Identifying problems early allows you to address them before they escalate.
Protect Your Investment
Whether you’re buying or selling a home, a sewer or septic scope provides valuable insight into the property’s overall condition.
Prevent Health Hazards
Damaged sewer lines or failing septic systems can lead to sewage backups, contamination, and serious health risks.
Gain Negotiation Power
For homebuyers, inspection results can be used to negotiate repairs or pricing with the seller.
Common Sewer Line Problems We Detect
Tree Root Intrusion
Tree roots naturally seek moisture and can infiltrate even small cracks in sewer pipes, eventually causing blockages or breaks.
Pipe Deterioration
Older homes often have sewer lines made of clay, cast iron, or Orangeburg, which are prone to deterioration over time.
Blockages & Buildup
Grease, debris, and foreign objects can accumulate in pipes, restricting flow and leading to backups.
Structural Damage
Shifting soil, ground movement, or heavy loads can cause pipes to crack, collapse, or become misaligned.
Signs You May Need a Sewer or Septic Scope
Even if you’re not buying a home, there are warning signs that indicate potential issues:
- Slow draining sinks, tubs, or toilets
- Frequent plumbing backups
- Unpleasant odors around drains or yard
- Soggy or unusually green patches in the yard
- Gurgling sounds in plumbing fixtures
If you notice any of these signs, a sewer or septic scope is highly recommended.
