Company Overview

Roy's service technicians strive for excellence to clear your sewer lines. We are known for being the preferred clog removal service for complex issues.

It all started with Roy and a simple pickup truck.

Over time, we’ve grown our offerings and added specialized vehicles to our lineup. Today, we manage a diverse fleet of service vans for drain cleaning, pumping septic tanks, root removal trucks for eliminating roots from sewer lines, CCTV trucks for assessing pipes from 6 inches to 48 inches, lateral inspection vehicles for inspecting laterals from the city sewer main, and Vactor combination trucks for hydro-flushing and clearing debris.

The founder launched Roy's Sewer Service in 1968 with his wife. As a team, they created a business that has survived the challenges of time and established itself as the preferred sewer and drain cleaning for property owners, commercial clients, and city services. I attended Sonoma State University and served as an accountant in the food service sector before becoming part of the family business in 2012. In 2020, I secured my contractor's license.

I work in the field operating our inspection and cleaning vehicles, maintaining and inspecting sewer systems. The office is run by my grandmother handles the administration, my dad leads the field crews, and my partner manages the pumping of septic tanks, drain cleaning, camera inspections, and operating heavy machinery.

We are excited to be a family-owned company. If you have any questions about our services, feel free to contact the staff and request me, or drop me a line at [email protected].

Two of my three sinks started backing up. I called Roy's Sewer Service Monday morning and by 2:00pm Mark had fixed the problems and made recommendations on how to keep things running in the future, all with a smile, confidence, and professionalism! Thank you Mark for being a huge help!

I don't often write Yelp reviews, but because of the terrific job Roy's did for us this morning, I feel compelled to write this. Overnight, our downstairs bathtub filled up with sewage back-up, which was obviously upsetting to us. We searched through Yelp and NextDoor and Roy's got really good ratings and it appeared that they specialize in sewers and drain repairs. I called this morning and the woman on the phone said they could get someone out today. About ten minutes later she called back and informed us that she had someone on the way. John showed up and immediately went to work to diagnose the problem. He got his rooter/snake machine out of his truck and proceeded to go to our clean-out and start working his way through the pipes. Within about ten minutes he found the problem, removed the blockage and our toilets and tub were back in working order. All was done within 45 minutes. He was fast, efficient and very professional. We're very pleased and will be happy to recommend Roy's in the future.

Thanks for literally NOTHING. My French drain was backing up. You sent a guy, he tried for two minutes to unclog. Ran a snake , that didn't help. Shot some water into the drain. Said he basically had no idea and CHARGED 225.00 !! I feel so ripped off. Nothing worse than paying a lot of money for literally NOTHING. I'd be happy to pay a small fee to come out BUT 225.00?????
Come on that SUCKS.

We have a kitchen sink drain that, without fail, get clogged every 6 months or so. Roy always fixes it for a reasonable price. I highly recommend his service.

Roy's helped us out in a bind. They were able to get people to our house quickly, and communicated about the exact time of their arrival. Ian and Mark were professional, knowledgeable, and hard working. I absolutely recommend Roy's.

Excellent Service!!
We will use Roy's again and again for our sewer Hydro Jetting with a camera to show what's going on underneath in our sewer line. Everything about this company is TOP SERVICE !

They actually came to clean out our sewer line that was not a thorough job from the previous plumber we used. THANK YOU!!

Curtis' ingenious method unplugged kitchen and bathroom sinks within 10 minutes this morning. The plumber who had examined the job yesterday proposed cutting and splicing the section of plugged pipe for $4000. Can you imagine?!
