How Much Does a Sewer Scope Inspection Cost?

Knowing the sewer scope inspection cost is valuable before buying a house. This type of inspection looks at the sewer line located under the ground where the line has cracks, obstructions, and tree roots entering the sewer line.
Buyers may not look at the sewer line because their attention might be drawn to the roof, HVAC system, and electrical aspects of the house. However, investing in an inspection before closing or when plumbing concerns first appear can provide peace of mind and help you avoid costly surprises.

Why Get Sewer Scope Inspections?

A sewer line inspection allows homeowners to detect underground plumbing problems before they develop into major repairs. Since sewer lines are buried beneath the property, issues often remain hidden until multiple fixtures begin showing symptoms.

Sewer line inspection is usually done to:

• Detect tree root intrusion before it clogs the pipe.
• Determine cracks, offset, or a collapse of the sewer line.
• Check old plumbing systems.
• Avoid costly repair jobs.
• Gain confidence before purchasing a property.

How Much Does Sewer Inspection Cost?

The sewer scope inspection cost depends on the property’s size, accessibility, and location.

Factors That Affect the Overall Cost

Several factors determine how much you’ll pay for an inspection.

1. Size of Property and Sewer Line Length

The length of the sewer line affects the amount of inspection time required, thereby increasing the labor cost.

2. Availability of the Sewer Cleanout

In cases where the cleanout is easily accessible, the process will take less time and the costs will be lower.

3. Location and Local Labor Prices

Prices differ depending on location since there are differences in labor charges and demand.

4. Age and Condition of the Sewer Line

Old sewer pipes made of materials like clay, cast iron, or Orangeburg are prone to decay, rust, and roots and eventually require extensive inspection.

5. Emergency or Same-Day Service

Requests for inspections beyond the standard office hours tend to cost more.

When Should You Get an Inspection?

There are several situations where scheduling a sewer scope inspection is strongly recommended.

Before Buying a Home

If you are asking yourself if you should get a sewer inspection done before buying a home in LA, then the answer should be yes. Mainly because problems related to sewer lines could cost you thousands of dollars to fix. A home inspection in Los Angeles is useful as it evaluates the underground system that isn’t typically examined during a standard inspection.

For Older Homes

Many older houses have old sewage lines that have possibly worn out over time. Even if the pipes are working perfectly fine, there could be defects underground.

Recurring Plumbing and Drainage Issues

Recurring drainage issues and bubbling taps are usually a sign of an issue in the sewer main line, not just a simple blockage. This is the reason why many people ask questions about drain backups, which are usually due to roots of trees, broken pipes, or a blockage in the sewer main line. Besides, foul odor from the sewers in your home may suggest leaks in the sewer main line.

Before Major Construction Projects

Checking on the sewer system before installing additional baths and plumbing is crucial for your renovations to go well without any unforeseen surprises.

What’s Included in a Sewer Scope Inspection?

During the inspection, a technician inserts a sewer inspection camera into the sewer line through an existing cleanout. The live video feed allows them to inspect the pipe without digging or damaging the property.

Inspectors typically evaluate:

• Cracks and fractures
• Tree root intrusion
• Pipe separation
• Corrosion
• Grease buildup or black mold growth
• Bellied pipe sections
• Blockages

Sewer Inspection Checklist for Home Buyers

Getting your sewer scope inspection done during the inspection contingency period will give you enough time to assess the condition of the property before making the purchase. In case you already have plans for carrying out the foundation inspection when buying a new home, the sewer scope inspection will definitely give you a broader view of the property’s condition.

Prior to any purchase, take into consideration the following checklist:

• The inspection should be scheduled during the contingency period.
• Confirm that a sewer line camera inspection is included.
• Ask for a written report including pictures or videos of the inspection.
• Check on the age and type of the sewer pipe.
• Inquire if repairs are needed.
• Get estimates for any repairs that are required.
