If any of these match what's happening at your home, call us — we can usually diagnose over the phone and tell you whether it's worth coming out same-day.
Sewage smell inside the house
Multiple drains backing up or gurgling
Soggy or unusually green patch in the yard
Toilet bubbles when the washing machine drains
Drains back up after heavy rain
Recurring main-line clogs
Sewer flies (drain flies) appearing indoors
Unexplained high water bill (broken pipe underground)
Most common causes
Tree root intrusion (very common in Salem)
Older Salem homes often have clay or cast iron sewer lines that are 40–80 years old. Tree roots find tiny cracks, enter the line, and grow — eventually blocking flow. Snaking clears them but they grow back. Long-term options are spot repair, pipe lining (no-dig), or full replacement depending on pipe condition.
Collapsed or bellied sewer line
Ground settling or poor original installation can cause a section of sewer line to sag (belly) or collapse. Bellies create low spots where waste pools and clogs repeatedly. Collapses block flow entirely. Camera inspection identifies the location; spot excavation or pipe lining repairs it.
Separated or offset joints
Clay sewer pipes installed before the 1970s often had hubbed joints that separate over decades of ground movement. Waste can leak out and roots can grow in. Usually spot repair is sufficient — full replacement isn't always needed.
Broken or missing cleanout
A sewer cleanout is an access point for inspecting and clearing the line. Many older Salem homes don't have one or have a buried/broken one. Adding a proper cleanout makes future maintenance vastly easier and is worth doing when we're already on-site.
Dry trap (if smell but no backup)
Sewer smell in a rarely-used bathroom or floor drain usually means the trap has dried out and the p-trap seal is gone. Running water to refill the trap fixes it. Always rule this out before assuming a main-line problem.
Sewer line problems sit in the category of "expensive to ignore, embarrassingly cheap to catch early." A $350 scope can tell you whether your 1970s home's clay sewer line is healthy or holding on by a thread — before a main line clog ruins your Sunday.
How to tell if the smell is a main line issue or something simpler
A sewer smell in a rarely-used bathroom, a basement floor drain, or a guest bathroom is almost always a dry trap. Pour a gallon of water down the drain — if the smell goes away, that was it.
A sewer smell near a toilet, especially if it's strongest when you flush, is usually a failed wax ring. Moderate repair, not a main line problem.
A sewer smell combined with slow drains throughout the house, gurgling, or backups is the real deal — that's when we scope the main line and find out what's actually going on.
Why you want to see the video
We give you the camera recording. Every time. It means:
You know exactly what's wrong with your line
You can get a second opinion if you want one
If you sell the house, you have documentation for the buyer
You never wonder whether the problem was as bad as we said it was
This is one of the places where we part ways from plumbers who work commission-based: we'd rather show you a minor root intrusion and recommend a $500 cleaning than sell you a $9,000 pipe line you don't need.
Here's how we work the job
We rule out easy causes first — dry traps, vent pipe issues, wax ring failures
We scope the main line with a camera and record the findings
We locate the exact spot of the problem with a sonde (surface locator)
We present options: another cleaning, spot repair, pipe lining, or replacement
You see the video before you decide. No pressure for bigger fixes than you need.
What it typically costs
Sewer camera scoping in Salem runs $350–$500 (often credited toward any repair). Spot repair typically $2,500–$5,500. Pipe lining (trenchless) $4,500–$9,000 per line, depending on length. Full replacement $6,500–$14,000 depending on depth, length, and property access. Every job quoted after scoping.
Frequently asked questions
Why does my house smell like sewage sometimes?
The most common cause is a dry p-trap in a rarely-used drain — floor drain, guest bathroom sink, basement shower. Every fixture has a trap that holds water to block sewer gas from entering the home. If the water evaporates, the seal is gone. Running water for 30 seconds in that fixture refills the trap. If the smell persists, the next suspects are a failed toilet wax ring, a vent pipe issue, or a break in the sewer line itself — which is when scoping makes sense.
Should I buy a house with an old cast iron or clay sewer line?
Not without scoping it first. A sewer line replacement in Salem can easily cost $8,000–$15,000 — that's a negotiating chip or a deal-breaker depending on condition. We do pre-purchase sewer scopes for buyers; it's one of the best inspection dollars you can spend on an older home.
What is pipe lining (CIPP) and is it worth it?
Cured-in-place pipe lining is a trenchless repair method where we insert a flexible epoxy-saturated liner into your existing sewer pipe, inflate it against the walls, and let it cure. The result is essentially a new pipe inside the old one with no trenching required. It's worth it when: the existing pipe is mostly intact, the path runs under hardscape or landscaping you don't want to tear up, and the line is under 80 feet. It's not worth it if the pipe is collapsed or severely bellied.
How often should I have my sewer line inspected?
For homes with mature trees or known root issues, every 2–3 years. For homes with modern PVC sewer lines, every 5–7 years or if you notice symptoms. For pre-purchase inspections, always.
What should I NOT flush?
Wipes (even 'flushable' ones), feminine products, paper towels, dental floss, food scraps, grease, coffee grounds, kitty litter, and hair. Only human waste and toilet paper should be flushed. This alone prevents most of the residential sewer clogs we see in Salem.
