If your toilet gurgles, your floor is mysteriously damp, or your kitchen sink keeps backing up no matter how many times it's "snaked" — the problem usually isn't where you think it is. It's somewhere in the 30 to 80 feet of drain line running under your house, and the only way to actually see it is to put a camera down there.
For a limited time, Element Service Group is offering free sewer line camera inspections to homeowners across the Triangle — Raleigh, Cary, Apex, Chapel Hill, Durham, Wake Forest, and Fuquay-Varina.
Here's what we've found in the last few months alone.
"My living room floor was wet — there was no leak anywhere I could see." (Chapel Hill)
A Chapel Hill homeowner noticed water seeping up through their living room floor. No visible plumbing fixture nearby. No obvious leak.
When our plumber Nick ran a sewer camera down the kitchen drain, the image stopped about 16 feet in — buried under the slab. We removed a 3-foot section of flooring and concrete and found the real culprit: a 2-inch PVC drain line packed with hardened grease, blocking the line completely and forcing wastewater sideways into the subfloor.
We cleared the line with pressurized water, milled the inside of the pipe for a clean run, ran a second camera pass to confirm it was spotless, and tested the flow.
What the camera saved them: trying to fix this without one would have meant tearing up a much larger section of floor — guessing where the blockage was. The camera narrowed it to a single 3' × 3' cut.
Pro tip from our crew: if your floor is wet and there's no visible leak, the drain line is the first place we'd look — long before anyone tears up your floors.
"Our toilets gargle every few days. It's been going on for months." (Cary)
A Cary homeowner had two toilets — master bath and hall bath — that would gurgle roughly once a week. No backup. Just the noise.
Nick and Bernard ran water through every fixture and couldn't reproduce a backup, which is exactly what told them the issue was intermittent — most likely a partial obstruction or venting problem somewhere in the main sewer line. A camera inspection was the only way to find it without guessing.
If you hear gurgling from your toilet or shower drain, especially after running the washer or dishwasher, it almost always means air is being pulled through your traps because something downstream is restricting flow. That can be roots, a partial collapse, or a sag in the line where water is pooling.
A camera tells you which one — before you spend money on a fix that doesn't address the real problem.
"Our cast-iron pipes are over 50 years old — should we be worried?" (Cary)
Short answer: probably yes.
A Cary homeowner suspected leaks in their cast-iron drain system. We sent a camera through and what we saw was the inside of a pipe that looked more like a coral reef than plumbing — heavy rust scaling, active corrosion, and a flow capacity reduced by more than half.
Cast-iron drain lines installed before the mid-1970s typically last 50–80 years. Once corrosion advances, you're looking at routine backups, sewer gas leaks, and eventually a collapse. We recommended replacing all the cast-iron piping in the crawlspace and the main sewer line out to the city tap with PVC — bringing the home up to current NC code in the process.
The camera turned a "should we worry?" into a documented decision. The homeowner could see exactly what they were dealing with, take it back to their seller for reimbursement negotiations, and move forward with eyes open.
"There's a sewer smell in the house and I can't find where it's coming from." (Cary)
A Cary homeowner noticed a faint sewer gas smell and slight floor damage. The camera traced it to a screw hole in a 3-inch PVC drain stack — someone had driven a screw straight through the pipe at some point, probably during a remodel. Sewer gas was leaking out of a hole the size of a pencil.
Nick repaired the section, retested the system, and the smell was gone the same day.
Without a camera, this is the kind of thing that takes a week of trial-and-error to find.
"We had a full-property drainage problem. Toilets, sinks, everything." (Apex)
An Apex homeowner was experiencing slow drainage across the entire house. A sewer camera traced it to a section of underground line that had been completely overtaken by tree root intrusion — the line was effectively wrapped in a fibrous mat from the inside.
Our team Nick and Travis excavated 4 feet down, replaced the drop service, installed a new sanitary tee and standpipe, and added a permanent clean-out cap so future inspections wouldn't require digging.
Roots find any crack in your line — and once they're in, they grow. A camera shows you exactly how far gone things are, and where to dig.
Why we're offering this for free
Most of the homeowners we meet have already spent money trying to fix a drain issue before anyone actually looked inside the pipe. They've paid for repeat snake-outs. They've paid for "we'll just dig and see." They've paid for repairs that didn't solve the real problem.
A camera inspection takes about 30–45 minutes and tells you, with video evidence, exactly what's happening under your house. No guessing. No upsell. If we don't find anything, you owe us nothing.
We're doing this because (a) we want homeowners in the Triangle to make decisions with real information, and (b) when we do find something, we'd rather you have us on the shortlist to fix it.
When to call us for a free camera inspection
Book one if any of these sound familiar:
- A toilet, tub, or sink that backs up repeatedly — even after snaking

- A home built before 1975 with original cast-iron drain lines
- Trees within 20 feet of your sewer line — especially mature oaks or maples
- You're buying or selling a home and want documentation of the line's condition
What's included
- Up to 100 feet of camera run through your main sewer line
- A live walk-through of what we see, in plain English
- Photos and video clips of any issue, sent to you afterward
- A written assessment with options — repair, monitor, or nothing needed
- Zero pressure. Zero obligation.
Where we offer this
Free camera inspections are available across our full Triangle service area — Raleigh, Cary, Apex, Chapel Hill, Durham, Wake Forest, Fuquay-Varina, and surrounding communities.
Frequently asked questions
How long does a camera inspection take?
Usually 30–45 minutes from arrival to walk-through. Longer if we find something worth documenting in detail.
Is it really free? What's the catch?
No catch. We'll inspect up to 100 feet of your main sewer line and send you the footage afterward. If we find an issue, we'll give you a written estimate to fix it — but you're under zero obligation to use us.
What if the camera can't get past a blockage?
That's actually useful information — it tells us roughly where the problem is. We'll quote a clearing option separately if you want us to keep going, but the initial inspection stays free.
Do you do trenchless repair if you find something?
For many situations, yes. We'll walk you through repair vs. replacement vs. lining options depending on what the camera shows.
Do I need to be home?
Yes — we want to walk you through what we find on the spot, on a screen, while we're still on-site.
