Expert Sewer & Drain Cleaning in Sunnyvale & The South Bay
From slow drains to major backups —restore your flow with Hydro Jetting and Rooter Service.
Our Diagnostic Approach
Stop Worrying About Backups
Don't guess what the problem is. We use advanced HD sewer cameras to diagnose the problem instantly without unnecessary digging. Whether it’s tree roots, grease buildup, or a collapsed line, we show you exactly what’s going on before we start work.
Hydro Jetting & Rooter Service
The Ultimate Clean for Clogged Drains.
Hydro-jetting is the most powerful way to clear stubborn blockages. Unlike snaking, which just punches a hole in the clog, our high-pressure water system scours the full diameter of the pipe, cutting through roots and flushing out sludge, grease, and debris.
Why Choose Hydro Jetting?
-
Like-New Pipes: Restores flow to the day they were installed.
-
Root Removal: Cuts through invasive roots that cause backups.
-
Safe & Effective: Cleans up to 150 feet of line without damaging your pipes.
-
Preventative: Identifying issues now prevents emergency sewer pipe blockage later.

FAQ
This section answers common questions.

How do I know if I need Hydro Jetting or Repiping?
If your pipes are structurally sound but clogged with grease or roots, hydro jet drain cleaning is usually sufficient. However, if the pipe has collapsed or is heavily corroded, trenchless pipe repair is the cost-effective, long-term solution.
-
What causes sewer line backups in the Bay Area?
The most common issues we see in Sunnyvale and Santa Clara are tree root intrusion into older clay pipes, grease buildup from kitchens, and shifting soil affecting pipe alignment.
