Mainline Rooter & Sewer Line Repair in Ontario, CA
At A&A Plumbing and Rooter Service, we’ve been clearing and repairing main sewer lines since the early 1970s. With decades of experience and a commitment to evolving with the latest technology, we offer efficient and affordable solutions for mainline backups, root intrusions, and pipe damage across Ontario and the surrounding Inland Empire.
Old-School Experience Meets New-School Tools
Back in the day, we measured snake cables and used a stethoscope to find pipe rattles. Today, we pair that experience with advanced sewer inspection cameras and underground locating equipment. This hybrid approach gives us pinpoint accuracy — so we can diagnose issues, give precise repair quotes, and minimize guesswork (and costs).
What We Fix
- Mainline root intrusion and blockages – Tree roots naturally seek moisture and can invade your sewer line through cracks or joints, causing slow drainage, backups, or complete blockages.
- Offset or collapsed sewer lines – Shifting soil, ground movement, or poor installation can cause pipes to break or misalign, disrupting flow and making cleaning tools ineffective until repaired.
- Pipe degradation or corrosion – Cast iron and other older piping materials can corrode, flake, or break down over time, reducing flow capacity and increasing the chance of leaks or full failure.
- Sewer backups into homes or yards – When a clog or break prevents wastewater from draining properly, it can back up into sinks, tubs, or even flood outside through cleanouts or low points.
- Recurring drain problems and slow flow – If you’re repeatedly dealing with slow drains or gurgling sounds, it often points to deeper mainline issues like buildup, partial blockages, or bellies in the line.
Our Repair Options
After a sewer camera inspection, our mainline technician will show you the issue and walk you through repair options that fit your budget:
- Spot Repair – Cut out and replace the damaged section
- Trenchless Pipe Bursting – Break and replace the pipe with minimal digging
- Pipe Lining – Insert a new epoxy liner into the existing pipe for a no-dig repair
Transparent Estimates, Honest Service
We don’t believe in surprises when it comes to pricing. That’s why we show you the issue on video and give you an upfront estimate before any work begins. Whether it’s a simple fix or a full trenchless repair, we’ll give you smart, cost-effective options.
