Our Drain Cleaning Methods
Professional Snaking & Power Rodding
For minor to moderate clogs, our team uses Spartan drain cleaning machines with precision cutting blades. These tools break through roots, grease, and debris without damaging your pipes. Power rodding, which employs rotating cables and blades, is ideal for cutting through thicker blockages and restoring full flow.
We avoid harsh chemical drain cleaners that can corrode your plumbing — every cleaning method we use is mechanical, environmentally safe, and built for lasting results.
Hydro Jetting (High-Pressure Water Jetting)
For the toughest clogs, nothing compares to hydro jetting. This advanced process uses a pressurized stream of water to scour your entire pipe — top to bottom.
Hydro jetting is especially effective for Seattle-area homes dealing with grease buildup, sludge, and tree root intrusion in older sewer lines.
Unlike traditional cable cleaning, which only cuts a path through debris, hydro jetting cleans the full diameter of the pipe. The jetter is also able to clean a larger diameter pipe than the cleanout would normally allow a cable machine — and we can clean up to 200’ in length.

Hydro jetting is safe for all types of drain lines, from residential kitchens to commercial sewer mains, and helps prevent future clogs by thoroughly flushing away buildup.
When to Schedule a Professional Drain Cleaning
You don’t have to wait for a total blockage to call us. Early warning signs can save you time, money, and stress. It’s time to schedule a professional cleaning if you notice:
- Slow draining sinks, tubs, or showers
- Gurgling noises or recurring backups
- Foul odors near floor drains or sinks
- Unexpected increases in water bills
- Standing water after using fixtures
Ignoring these issues often leads to larger plumbing problems. Our technicians will inspect, clean, and verify your drains — often within the same appointment — so you can get back to your day!

Preventative Maintenance & Routine Inspections
The best way to avoid major plumbing headaches is through routine maintenance. Regular drain cleaning helps extend the life of your pipes, prevent leaks, and reduce costly emergencies.
At Bob Oates, every cleaning includes a complimentary camera inspection. This ensures we’ve fully removed the blockage and gives you a clear picture of your system’s condition.
We also offer seasonal drain cleaning specials for Seattle homeowners, making preventative care both simple and affordable. Because a little maintenance today can prevent standing knee-deep in water tomorrow.
Bob Oates techs always get to the "root" of the problem — like this 300-pound tangle of tree roots pulled from a clogged sewer line to get the drains flowing again.

FAQs About Drain Cleaning Services
What are signs that I need professional drain cleaning?
Common signs include slow drains, recurring clogs, foul odors, gurgling sounds, and sewage backups in tubs and floor drains. Pooling water near downspouts outside the home can also be a warning sign. In homes around Seattle, heavy rain, older plumbing systems, and tree roots can all contribute to sewer line clogs and backups.
What drain cleaning methods do you use?
We use professional equipment such as drain snaking cable machines, augering, and high-pressure water jetting, also known as hydro jetting. These methods remove grease, scale, and debris from pipe walls for a thorough clean. Because many properties in Seattle have older plumbing and every situation is different, we inspect the system first and tailor our approach to the specific issue.
Is hydro jetting safe for my pipes?
Yes, when performed by a trained technician and used on compatible pipe materials. We inspect first to confirm that hydro jetting is appropriate.
How can I prevent future clogs?
Avoid disposing of grease, wipes, hygiene products, and excess food scraps in drains. Use drain strainers and schedule preventive cleaning, especially in older homes or homes with large trees.
How often should drains be cleaned?
Many homes benefit from preventive cleaning every 1 to 2 years. High-use kitchens, older piping, or properties with frequent backups may need service more often.
Will drain cleaning fix a sewer line problem?
Drain cleaning clears blockages, but if the underlying issue is a broken or root-intruded sewer line, a camera inspection and repair plan may be needed.
Do you offer emergency sewer and drain services?
Yes. We provide fast-response emergency sewer and drain services throughout the greater Seattle area, from Edmonds to Tacoma and many places in between. If you are dealing with a sewage backup or serious drain clog, contact us immediately at 206-789-4944 to help prevent further damage.
How quickly can you arrive for service?
Emergency calls are prioritized for the fastest response, typically within 2 hours. For non-emergency calls, we offer same-day or next-day service whenever possible across Greater Seattle and surrounding areas.
How much does drain cleaning cost?
Costs vary depending on the severity and location of the clog. We offer free onsite estimates and upfront, transparent pricing with no hidden fees or surprises. Be sure to check our current specials and coupons.
