Sewer Line & Mainline Repair in Greater Cincinnati
Water line or sewer mainline issues? Queen City Plumbing uses camera inspection to pinpoint the problem before touching a shovel — then gives you a flat-rate quote for repair or replacement. No guessing, no unnecessary excavation.
Water Main & Sewer Line Repair
Mainline repairs are high-stakes jobs — they affect your whole home's water supply or drainage, and they often involve excavation. We approach every job with a camera inspection first so we know exactly what we're dealing with. That means accurate quotes, targeted work, and no costly surprises mid-job.
Camera Inspection First
We run a camera down your main before proposing any repair. You see exactly what we see — the blockage, the crack, the root intrusion, or the collapse. No digging based on guesswork. Learn about our sewer camera inspections →

Mainline Repair Questions
Signs include multiple drains backing up at once, gurgling sounds from toilets when other fixtures run, sewage smell in the yard or basement, wet spots or sinkholes in the yard above your sewer line, or unexplained spikes in your water bill. Any of these warrant a camera inspection. Call 513-540-4575 and we'll diagnose it.
In most cases the homeowner owns and maintains the sewer lateral, the line that runs from the house out to the public sewer main. The exact dividing point depends on your city or sewer district, so check with them if you're unsure. If we find a problem, we'll show you on the camera where it is along the line and give you a flat-rate quote for the repair.
It varies significantly based on the type and extent of the problem. We won't know the right number until we run the camera. What we commit to is giving you a flat-rate quote before any work begins — no open-ended billing.
