Should You Get a Sewer Scope Before Buying in Cobb County?
Due diligence is short and there is a lot to spend money on. Here is how to decide whether this particular check earns its place on a given house.
Under contract already?
Book it inside the due diligence period. After closing, the same finding is entirely your problem.
- TIME ON SITE
- Usually under an hour.
- NOT INCLUDED IN
- A standard home inspection.
- MOST USEFUL ON
- Houses built before about 1980.
What a standard inspection actually covers
A general home inspection in Georgia is a visual assessment. The inspector looks at what can be seen and operated, which is a genuinely valuable exercise and is not the same thing as looking inside the drainage system.
The sewer lateral, the pipe running from the house to the public main, is not part of it. That pipe is the property owner's responsibility once you buy, it is buried, and replacing a failed one is among the most expensive single repairs a residential property can produce.
A scope is a separate booking, usually an hour, and it is one of the cheaper line items in due diligence. Whether it is worth it depends almost entirely on the age of the house.
When it is clearly worth booking
The strongest case is a house built before about 1980 in this part of the county. That is the era of vitrified clay and cast iron laterals, laid in jointed sections, sitting in Piedmont red clay that moves seasonally between a wet spring and a dry August.
Add mature trees, which south Cobb has in abundance, and the mechanism is simple. Joints open fractionally, moisture escapes, and root systems follow it in. A camera either shows that happening or shows a sound line, and both answers are worth having.
The case weakens considerably on a house built in the last twenty five years on PVC drainage. It is not pointless, since bellies and construction damage exist at any age, but the base rate of serious findings is far lower.
| When the house was built | Likely lateral material | Typical finding rate | Worth booking? |
|---|---|---|---|
| Before 1960. | Vitrified clay, some cast iron. | High for root intrusion and offset joints. | Strongly yes. |
| 1960 to 1980. | Clay or cast iron. | Meaningful, particularly under mature trees. | Yes. |
| 1980 to 1995. | Transitional, often PVC. | Lower, but bellies do occur. | Worth it on a larger purchase. |
| 1995 onward. | PVC. | Low, mostly construction related. | Optional, judgement call. |
| Any age with a history of backups. | Whatever is down there. | High by definition. | Yes, regardless of age. |
| Any age with large trees over the run. | Depends on material. | Higher than the era alone suggests. | Yes. |
What you are buying is a number for the negotiating table. A scope that finds a failing lateral does not stop you buying the house. It gives you a documented, priced defect to raise before closing, which is a very different position from discovering it in month two.
What the camera can and cannot settle
It reliably answers four things. What the pipe is made of, whether there is a blockage and what it consists of, whether a section has dropped out of line and is holding water, and exactly where any fault sits and at what depth.
It does not reliably answer how long the line has left. Condition is visible, remaining life is a judgement, and anyone converting twenty minutes of footage into a confident five year prediction is overselling the tool.
It also usually identifies where the property's responsibility ends and the public connection begins, although boundary questions occasionally need the utility involved to settle properly.
What to insist on when booking one
The last two matter together. A company that can only clean has an incentive to see cleaning, and one that can only sell replacement has the opposite bias.
- That the recording is handed to you, not just described.
- That any fault is located and marked at ground level with a depth noted.
- That the run reaches the connection rather than stopping at the first bend.
- That you are told plainly if the finding is cleaning rather than repair.
- That the inspection charge and any repair quote are kept separate.
- That the plumber is licensed in Georgia and can actually carry out what they recommend.
The local specifics that shape findings here
In Austell and the surrounding south Cobb towns the recurring finding is root intrusion at clay joints rather than collapse. Roots do not attack sound pipe, they follow moisture and oxygen escaping from a joint that has already opened, which is why the repair that ends the cycle is at the joint and annual root cutting is not.
The second recurring finding is a belly, a section that has settled and now holds standing water. Relining will not fix that, because a smooth dip is still a dip, so it is one of the few findings that genuinely requires excavation.
Reading the result without panicking
Not every finding is a deal issue. Grease and scale with no structural fault is a cleaning job and nothing more, and it should be reported that way rather than dressed up.
Root hair through a joint on a fifty year old clay lateral is common, manageable and worth pricing, and it usually leads to jetting and a cutting head followed by a decision about the joint itself. A collapsed section or a significant belly is a different conversation, and it belongs in sewer line repair territory with a real number attached.
If the footage is clean, you have bought certainty on the one part of the property nobody else looked at. The mechanics of how the run is carried out are set out on our camera inspection page.
Georgia amendments to the adopted plumbing code require cleanouts on building sewers, which is why most houses here have an accessible access point. If a property genuinely has none, that is itself worth knowing before you buy, because every future clearance becomes harder and more expensive.
Quick answers
Buyer questions about sewer scopes
Can the seller refuse to allow a sewer scope?
Access is negotiated like any other inspection, and it is normally arranged through the same channel as the general inspection during due diligence.
A refusal is itself information. It is not proof of a problem, but it is a reasonable thing to weigh.
What if the house has no accessible cleanout?
The camera can sometimes be run through an interior access point instead, though it is slower and less convenient. Where access has to be created, that changes the cost and you should be told before anything happens.
The absence of a cleanout is worth noting in its own right, since Georgia's adopted code requires them on building sewers and every future clearance is harder without one.
Is a scope worth it on a house built in 2010?
Less so. PVC drainage of that age rarely produces the root and joint failures that drive most findings, so the base rate is low.
It is still a judgement call on a large purchase, and it becomes worthwhile if there are mature trees over the run or any history of drainage complaints.
If the scope finds a problem, can I use it to renegotiate?
That is exactly what the footage is for. A documented, located fault with a repair quote attached is a concrete item rather than a vague concern, which is a much stronger position.
Keep the recording regardless of what you decide, because it also becomes your baseline record after closing.
