A home inspection rarely includes the sewer line — and on an older Westside house, that’s exactly where a five-figure surprise can hide. A quick camera scope before closing tells you what you’re really buying.

A sewer inspection before buying a house sends a camera down the property’s sewer line to reveal its condition before you close — roots, cracks, bellies, or a collapse. On an older home it’s one of the smartest pre-purchase checks, because a failed line is a five-figure repair the standard home inspection won’t catch.
Most buyers get a general home inspection and assume it covers everything. It rarely covers the sewer line — the buried lateral that carries waste from the house to the city main. On an older home, that line can be the single most expensive thing to fail, and you won’t know its condition unless someone puts a camera in it.
Sewer inspection before buying a house — A sewer inspection before buying a house is a pre-purchase sewer camera scope of a property’s sewer lateral, done during escrow to document the line’s condition before the sale closes.
If a scope turns up damage, the good news is that most Westside lines can be fixed with trenchless sewer repair rather than a dug-up yard — but you’ll want that priced before you close, not after.
The full lateral from the house to the city connection, on camera. See our sewer camera inspection.
You get options and a flat-rate quote — often CIPP lining — to negotiate before closing.
It’s quick, and it fits inside a normal escrow timeline.
We fit the scope into your inspection window so findings inform the deal.
Through an existing cleanout, or by pulling a toilet if there’s no cleanout.
We run the camera the full length and record the condition.
We mark the depth and spot of roots, cracks, bellies, or collapse.
You get footage and a plain-language summary for your agent.
If there’s damage, you get a flat-rate repair number to negotiate with.

| What we find | On camera | What it means for the deal |
|---|---|---|
| Roots | Fine roots at a joint | Negotiate descaling / lining |
| Belly | Standing water in a low spot | Negotiate excavation or re-grade |
| Collapse | Crushed or caved pipe | Major — negotiate replacement |
If the scope finds damage, our trenchless sewer repair cost guide helps you price it, or start with the no-dig sewer repair overview.
A pre-purchase sewer scope is inexpensive next to what it protects — a small, fixed fee against a repair that can run five figures. Pricing depends mainly on access: an existing cleanout keeps it simple, while pulling a toilet adds a little. It’s among the cheapest insurance you can buy in a home purchase.
If the scope finds damage, we fold the findings into a flat-rate repair quote — see trenchless sewer repair cost — so you can negotiate with a real number.
A buyer loves a 1948 Mar Vista bungalow and is days from closing. The home inspection was clean, but no one has looked at the sewer.
New Pro scopes the lateral and finds roots and a cracked section on camera, with footage and a written summary delivered same day.
The buyer negotiates the seller into covering the repair — turning a hidden five-figure liability into a line item in the contract.
The Bottom Line
The sewer line is the most expensive thing a standard home inspection misses. On an older Westside home, a quick scope before closing is cheap insurance: either you get peace of mind, or you get leverage. Both are worth far more than the scope costs.
On an older home, yes. The sewer line isn’t part of a standard home inspection, and a failed line is a five-figure repair. A quick camera scope before closing either confirms it’s sound or gives you leverage to negotiate.
Usually not. A general home inspection covers visible systems, not the buried sewer lateral. A separate camera scope is the only way to see the line’s real condition.
It’s a small, fixed fee relative to what it protects — dependent mainly on access. An existing cleanout keeps it simple; pulling a toilet adds a little. We quote it up front.
You get footage, a written summary, and a flat-rate repair quote you can bring to the negotiation — so the cost can become the seller’s responsibility before closing.
Yes. We schedule it inside your inspection window so the findings can inform the deal before it closes.
Usually under an hour, and you get the footage and summary the same day.
