"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"I had a great experience with a drain cleaning service at my home in Los Alamitos. Our main line was backing up, and they were able to get someone out the same day. Our technician Brandon was professional, knowledgeable, and took the time to explain what was causing the blockage and how he was going to fix it. He thoroughly cleaned the drain and made sure everything was flowing perfectly before leaving. You can tell he really cares about doing the job right. I appreciate the honest service, fair pricing, and quick response. I would definitely recommend Brandon to anyone in Los Alamitos who needs reliable drain cleaning service!"

"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."

"I had a great experience with The Sewer Boyz when they came out to locate and repair my sewer line. Jonathan made the whole process smooth and reassuring from start to finish. He took the time to explain how he would locate the line, clearly identified the problem, and walked me through the repair options without any pressure. His knowledge and professionalism immediately gave me confidence. The repair was done efficiently and with great attention to detail, and he made sure everything was working perfectly before leaving. What really stood out was how respectful and personable Jonathan was. He treated my home with care, cleaned up thoroughly, and made sure I understood everything that was done. I truly appreciate his honesty and quality of work. Highly recommend this company. Definitely a 5-star experience!"

French Drains FAQs, answered by experts

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

Yes, frozen pipes can prevent a toilet from working correctly. If the pipes are frozen, water cannot flow, which means your toilet tank won't be able to refill after a flush. This will prevent the toilet from flushing again. Depending on which lines are frozen, the ice can also block the drain pipe, preventing water from flushing away.

As a temporary workaround, you can manually add water to the tank for each flush. To clear a frozen drain pipe, you can try filling the toilet bowl or tank with warm water and flushing to help thaw the ice. However, the best long-term solution is to unfreeze the pipes to get your toilet back in working order.

If you don’t have a sewer cleanout, clearing out clogs can be extremely difficult. You would need to try to clear the clog from sink drains, but it can be harder to reach the clog all the way in the drain line. A sewer cleanout makes it much faster and easier for pros to clear clogs from your main sewer line.

You should inspect and clean your French drain at least once per year to keep it in good working order. Regular maintenance can help identify clogs, buildup, and damage before they become bigger problems, which increases the lifespan of your drain. The frequency with which a drain clogs can depend on factors like the amount of debris, the quality of the installation, and the type of filter used. If your drain accumulates a lot of sediment, it may require more frequent cleaning. It's also a good practice to check the access and exit points after heavy storms. If you notice reduced drainage or any signs of a clog, clean the drain as soon as possible.

The cost to clean a sewer line is about $370, ranging from about $190 to $550 on average. The specific cleaning method and the problem's severity will impact the project's overall cost. Some of the most common sewer line cleaning methods include:

  • Snaking or rodding: $100–$250

  • Hydrojetting: $350–$600

  • Chemical treatments: $600–$1,000

  • Repair or replacement: $1,000–$7,500
