Drain Cleaning & Clog Removal in Knoxville, TN
Kitchen sinks, showers, tubs, floor drains, and main sewer lines — cleared properly and kept clear, not just pushed downstream.
Symptoms Knoxville homeowners call us about
- Kitchen sink drains slowly or backs up when the dishwasher runs
- Shower or tub fills up around your ankles while you shower
- Multiple drains gurgle or back up at the same time
- Floor drain in the basement backing up during heavy rain
- The same drain clogs over and over no matter what you do
One slow drain often points to a local trap or branch restriction, while several fixtures backing up together raises concern for a larger branch or main sewer issue. A floor drain that backs up during rain can have several possible causes depending on how the home's drainage is configured. The symptom pattern helps narrow the search, but we confirm before assuming.
Still not sure what's going on?
Our AI Plumber can help you narrow it down — describe what you're seeing and it'll walk you through likely causes, safe checks, and whether it's a DIY job or time to call a professional.
What's usually behind these problems
- —Grease and soap buildup in the trap or branch line
- —Hair and debris caught in the trap
- —Food and grease in the kitchen line
- —Main line blockage from roots or partial collapse
- —Vent problem causing slow drainage and gurgling
- —Scale and corrosion in older cast iron lines
We clear the full line, not just a hole through the clog
A cable that pokes a hole through a clog leaves the buildup on the pipe walls — and the clog returns next week. We clear the full line, and when a clog is recurring we camera-inspect to find the real cause: grease, a sag (belly), roots, or a partial collapse.
For grease and scale, hydro jetting scours the pipe wall clean where a snake can't. For a main line, we clear first, then camera to confirm whether a repair is needed so you're not back here next month.
How we diagnose and fix it
- 01Identify the scope
One fixture or the whole house — the pattern tells us whether it's a local clog or a main line problem.
- 02Clear the line
We snake or cable the affected line, clearing the full blockage — not just a hole through it.
- 03Camera when recurring
If a drain clogs repeatedly, we camera-inspect to find the real cause: grease, a belly, roots, or collapse.
- 04Explain the cause
We show you what we found and whether a repair is needed to stop the cycle.
- 05Recommend prevention
We tell you what caused it and how to keep it from coming back.
Clearing the Clog Is Only Part of the Job
- If the same drain keeps clogging after proper clearing, a camera inspection or other deeper evaluation may be worthwhile to look for buildup, a sag, roots, damage, or another underlying cause.
- Chemical cleaners are corrosive, can damage older pipes, and rarely clear the full blockage.
- Hydro jetting scours grease and scale where a snake can't — the right tool for recurring grease clogs.
- If camera findings show structural damage, recurring root entry, or a significant sag, clearing may restore flow temporarily while repair or replacement addresses the underlying condition.
- A clog that affects multiple fixtures at once raises concern for a shared branch, building drain, or sewer-line restriction. Stop using water if fixtures are backing up and have the drainage layout evaluated before assuming the exact location.

Genuine reviews from real service calls — not fabricated.
Camera inspection found tree roots in our sewer line that two other companies missed. Showed me the video, explained the options honestly, and the repair has held perfectly.

Drain Problems We Commonly See in Knoxville Homes
Many Knoxville homes have cast iron drain lines that can develop internal scale and corrosion over time, which may catch debris and contribute to recurring clogs. Camera findings, clearing results, access, leak history, and the overall condition of the system should be considered together before deciding whether maintenance, a spot repair, or broader replacement makes sense.
Mature trees in older Knoxville neighborhoods are a frequent cause of root intrusion in clay and cast iron sewer lines, and the hilly terrain can produce bellies (sags) in lines that collect debris and clog over and over.
