When buying a home, most buyers focus on the structure, electrical, plumbing, and HVAC systems—but one crucial area often goes overlooked: the sewer line. A sewer scope inspection is a specialized service that can save homebuyers thousands of dollars by identifying hidden issues before closing. But is it worth the extra cost? Let’s explore what a sewer scope inspection is, why it matters, and when you should consider adding it to your home inspection checklist.
What Is a Sewer Scope Inspection?
A sewer scope inspection involves using a small, high-resolution camera attached to a flexible cable that is inserted into the home’s sewer line. This camera provides a real-time video feed, allowing the inspector to assess the condition of the sewer pipes, identify blockages, and check for damage or deterioration.
Why Are Sewer Scope Inspections Important?
Many homebuyers assume that if the plumbing inside the house works, the sewer system is in good shape. However, sewer line issues are often hidden underground, making them impossible to detect without a camera inspection. Here are a few reasons why a sewer scope inspection is valuable:
Detects Blockages & Clogs – Tree roots, grease buildup, and debris can cause slow drainage or full blockages.
Identifies Pipe Damage – Cracks, corrosion, or collapsed pipes can lead to costly repairs.
Prevents Expensive Repairs – Sewer line replacements can cost anywhere from $3,000 to $30,000
Provides Peace of Mind – Knowing the sewer system is in good condition helps buyers make informed decisions.
When Should Buyers Get a Sewer Scope Inspection?
Not every home needs a sewer scope inspection, but it is always recommended, definitely consider getting one if:
The Home is Over 20 Years Old - Older homes often have clay or cast-iron pipes that deteriorate over time.
There Are Large Trees on the Property - Tree roots can invade sewer lines, causing blockages or breakage.
You Notice Slow Drains or Plumbing Issues - Gurgling sounds, backups, or frequent clogs can indicate a problem.
The Home Has a History of Sewer Issues - Previous backups or repairs could signal ongoing problems.
It’s a Fixer-Upper or a Foreclosed Property - Unoccupied or neglected homes may have hidden sewer damage.
New Build Homes- Sometimes builders forget to connect the home's sewer line to the main city line.
What Happens if Problems Are Found?
If the inspection reveals issues, the next steps depend on the severity of the problem:
Minor Issues (small clogs or debris) – These can often be cleaned out with professional drain cleaning.
Moderate Issues (tree roots, minor cracks) – May require hydro jetting or pipe relining to prevent further damage.
Severe Issues (collapsed pipes, major blockages) – A full sewer line replacement might be necessary, and buyers may negotiate repairs with the seller.
Final Verdict: Is It Worth It?
A sewer scope inspection typically costs between $200 and $250, a small price compared to the potential cost of sewer line repairs or replacements. If you’re buying an older home, notice plumbing issues, or just want peace of mind, investing in this additional inspection can save you from major headaches down the road.
Before purchasing a home, be sure to ask your home inspector about sewer scope inspections—it could be the best decision you make!
