When drains slow down, gurgle, or back up, the problem is usually somewhere you can't see — inside the sewer lateral running from your house to the street or septic connection. Guessing at the cause from inside the house leads to wrong fixes: snaking a line with a collapsed section, or replacing a line that only needed cleaning. A sewer camera inspection removes the guesswork entirely. The camera travels the line and puts the inside of your pipe on a monitor in real time. Here's what it finds.
1. Tree root intrusion
The most common find in established neighborhoods. Roots seek moisture, find tiny openings at pipe joints, and grow into dense masses that catch paper and waste. The camera shows exactly which joints are invaded and how severe the blockage is — information that decides between a cleaning and a repair.
2. Cracked or broken pipe
Shifting soil, heavy loads above, and simple age crack sewer pipe. The camera reveals fractures ranging from hairline cracks to fully collapsed sections, and the footage markers record exactly how far from the access point the damage sits — so any excavation targets one spot.
3. Bellies: sagging sections
A belly is a low spot where the pipe has settled, letting water and solids pool instead of flowing away. Bellies cause chronic slow drains and recurring clogs in the same fixtures. On camera, standing water in an otherwise dry line is the giveaway — and the footage shows precisely where the sag begins and ends.
4. Offsets and separated joints
Where two pipe sections meet, ground movement can shift them apart, creating a lip that snags waste. Older clay and cast-iron lines are especially prone to joint separation. The camera shows the step or gap clearly, and the severity determines whether it needs lining, spot repair, or replacement.
5. Blockages and grease buildup
Kitchens send grease down the drain, and grease cools, hardens, and narrows the pipe from the inside. The camera distinguishes a soft grease blockage (often clearable with jetting) from a hard obstruction or structural problem — a distinction that matters enormously for the fix.
6. Scale and corrosion
Cast-iron sewer lines corrode from the inside out, building up rough scale that catches debris and eventually eats through the pipe wall. The camera shows the pitted, flaking interior surface long before it fails completely — early warning that a replacement conversation is coming.
What the camera sees in different pipe materials
The footage tells a different story depending on the pipe's era. Clay tile lines — common in older Summerville homes — show root intrusion at the joints first, with the roots growing denser at each successive joint downstream. Cast-iron lines show interior corrosion: rough, flaking walls that narrow the pipe and snag debris, sometimes with channels worn into the bottom. PVC and other plastic lines, where present, generally show fewer material failures — problems there are usually bellies from poor bedding or offsets from ground movement. Knowing the material before the camera goes in sets expectations for what the footage is likely to reveal.
What happens during the inspection
The technician feeds the camera through an existing cleanout or pulled toilet — no digging. You watch the live feed together as the camera travels the line, with distance markers tracking its position. The visit typically ends with recorded footage and a plain-language explanation of what's normal, what's not, and what (if anything) needs attention.
What a camera can't tell you
An honest note: cameras see the inside of the pipe, not the soil around it. They can't measure how much pipe wall remains in a corroded line, and they can't see a leak that's outside the pipe. For those questions, other methods apply. But for diagnosing what's happening inside the drain, nothing beats a direct look.
When Summerville homeowners should get one
Consider an inspection with recurring clogs in the same drain, gurgling fixtures, sewage odors, soggy patches over the lateral's path, or before buying an older home — a failed lateral is one of the priciest surprises in real estate. It's also the smart first step before any sewer repair quote, so the work targets the real problem. Call +1 843-936-8115 — open 24 hours.
