Drain cleaning in Knoxville, TN typically costs between $194 and $260, depending on where the clog is and how it is reached. A single-fixture clog is cleared with a hand auger at that drain; a main line backup is cabled through a cleanout, and a line that keeps clogging gets a camera run to find the cause.
Updated October 2026
One Clogged Fixture or the Whole House
The first question is how many drains are affected. One slow sink or tub is a clog in that fixture's branch, usually hair, soap or grease, and it clears from that drain. Water backing up in a tub when the toilet flushes, or in a floor drain when the washer empties, means the main line is blocked, and that's cleared from a cleanout.
Most clogs clear with a cable. When the same drain clogs again within months, a camera inspection shows whether roots, a sag or a broken joint is behind it, and high-pressure jetting is often the better cure for grease.

Kitchen Sink Clog
Kitchen clogs are grease and food: fat goes down warm and sets up a few feet into the drain, then catches everything else. Disposals make it worse when they are used for peels, rice or coffee grounds. We clear the line past the trap arm with a cable sized for the branch, not just the trap, and flush it with hot water. If the clog sits where the kitchen line joins the main, both sides of a double sink back up at once, and that tells us where to work.
Bathtub and Shower Drain
Tub and shower drains clog with hair and soap scum that build up in the first foot of pipe, often wrapped around the stopper linkage itself. Many clear just by pulling the stopper and cleaning it, so we start there. Past that, a drum auger through the overflow reaches the trap and the branch beyond. If a tub drain gurgles or rises when a toilet flushes, the problem is further down the line and belongs with the main, not the tub, however clean the stopper looks.
Main Line Clog
A main line clog backs water up at the lowest drain in the house: a basement floor drain, a first-floor tub or shower. The fix is a larger cable machine through the outdoor cleanout, or through a roof vent or pulled toilet when there is none. Once the line is open, we run water to confirm flow and ask when it last happened. A main that clogs more than once a year is telling you something about the pipe, and a camera run turns that guess into an answer.
Floor Drain Backup
Basement and garage floor drains back up for two reasons: a clog in the main line below them, or a clog in the floor drain's own trap from dirt and debris. Water that comes up when the washer drains points to the main. Water that sits in the drain and goes nowhere points to the trap. Floor drains also dry out and let sewer gas in when nothing ever runs down them, so a cup of water poured in every few weeks keeps the trap sealed and the basement smelling normal.

Drain Clogs You Can Try Before Calling

| Job | Reasonable DIY? | Why |
|---|---|---|
| Plunging a sink or toilet | Yes | Use a flange plunger on toilets and seal the overflow on sinks |
| Cleaning a tub stopper | Yes | Most hair clogs sit on the stopper linkage |
| Chemical drain openers | No | Rarely clear a full clog and are hard on old pipe |
| Main line with sewage backing up | No | Stop using water; it needs a cleanout and a large cable |

Drain Cleaning Questions From Knoxville Homeowners
Are chemical drain cleaners safe for my pipes?
They are hard on older metal pipe and rarely clear a full clog, and they make the job hazardous for whoever clears it next.
Why does my drain clog every few months?
Grease buildup, roots or a sag in the line. A camera run shows which one.
Can you clear a drain without a cleanout?
Yes, through a roof vent or a pulled toilet, which takes longer. Adding a cleanout helps every future call.
Is the garbage disposal to blame?
Often. Peels, rice, pasta and coffee grounds pack the line below it.
Can drain cleaning damage pipes?
A properly sized cable does not. Fragile old pipe is handled carefully and inspected first.
How do I prevent kitchen clogs?
Keep grease and starchy scraps out of the sink, and run hot water after the disposal.
