"Jonathan Zavala and his team are amazing!! We recently bought a house which we knew needed a little plumbing work. Of course it's every home owner's nightmare when a "little" work turns out to be a lot! We really thought we'd be stuck dealing with plumbing repairs for weeks, but Jonathan and his crew knocked out the major work we ended up needing in mere hours. We also ended up paying 25% less than other plumbers quoted. They even dealt with our nosy and cranky neighbors extremely professionally, which we really appreciated. I am blown away with the efficiency and competence of The Sewer Boyz. Easily the best hire we've made, and I will never hire another plumber again! I told Jonathan he's stuck with us for life now, haha. We will refer all of our friends and family without hesitation. If you are looking for an honest, skilled, fast, and reliable plumber, you won't find a better one than The Sewer Boyz. Just hire them and thank me later :)"

"We had a major sewer main blockage at our home and it turned out to be caused by heavy root intrusion. Mike, the technician, did an excellent job diagnosing the issue quickly and explaining everything in a way that was easy to understand. He showed us what he found and recommended hydro jetting to properly clear the line. Mike was very professional, thorough, and made sure the sewer line was completely cleaned out before finishing. The hydro jetting worked perfectly and everything has been flowing great since. On top of that, the price was very reasonable for the amount of work and the level of service we received. I really appreciate the honesty, quality work, and peace of mind. Highly recommend Mike if you?re dealing with a sewer blockage!"

"Great service and work from Miguel and team. I would hire them again. What originally was a slow draining sewer line turned into a root infested backup. Miguel was able to scope the drain and visualize the root of the problem. They were prepared to start digging and had the tools and supplies on the truck to get the job completed. He clearly explained the discovery, repair, and installation process as well as potential other root intrusion spots. After the dig, the soil and grass was replaced and can hardly tell that any work was done. They also cleaned the dirt/mud on the concrete walk way. Thank you Miguel and team for the great work."

Sewer Cleaning FAQs, answered by experts

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

Homeowners insurance usually doesn’t cover sewer backups because it’s typically an avoidable problem with proper maintenance. The only exception would be if the backup is occurring because of local flooding and only if your city uses a combined drainage system for stormwater and sewage. If that’s the case, your policy should cover any resulting damage.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease. 

Snaking a toilet is similar to clearing sinks and bathtubs, but there are unique circumstances where you’d have to drain, disassemble, and remove the toilet to fix the clog. For stubborn clogs in the toilet trap, a toilet auger—designed with a shorter cable and a protective plastic encasing—can navigate the tight bends and clear the clog without risking damage to the porcelain.
