"Everyone I contacted (this is my second experience with them) has been friendly and ready to help. Technician arrived early, diagnosed the problem, performed the work, even showed me with a camera that the entire main sewer line was cleaned. Worth my time and money, will use them again (old house)."

"I got a call from Kyle around 4:55 pm. He said he was able to come out around 7 pm, keep in mind, Hyper Flow closes at 5 pm. Kyle came out of his way after hours, ran a camera through my sewer line, snaked out the line, and then showed me on the camera the second time that the line was clearish. My main sewage line has been building up for a few years. Kyle gave me 3 different estimates for futures maintenance. I have already made an appointment for Kyle to come back out and do some more work. He is very up front, honest, and caring. He isn't just trying to get paid, Kyle is aware that life happens and works with customers to do what works best financially for the customer at the time of the job. I would recommend Kyle and Hyper Flow to anyone who is looking for a plumber with years of experience and has the best intrest for his customers."

"We called on a Saturday for emergency service and within about 45 minutes the plumber had arrived. He used a roto-rooter type tool to clean out the sewer line. The work was done well and the plumber was very friendly and professional."

"I hired GoldStar to replace the main sewer pipe two weeks ago. I am very impressed by the excellent customer service I received. After I talked to Tran, he did an accurate measurement in a day or two and provided a very reasonable quote. Once I gave the green light to proceed, he got the work scheduled and coordinated with the two inspectors required for the project. Although there was something unplanned like any project that happened onsite, the worker told me honestly, and Tran took care of it without fuss. The payment options are very smooth as well. The quality looks good from the layman's eye. I trust the inspectors did their job to validate. More importantly, I am glad GoldStar does it. The bottom line: if you need an honest contractor to do a similar job, I highly recommend GoldStar."

Sewer Cleaning FAQs, answered by experts

Even with a high-resolution camera, what you're looking at on the screen may not be recognizable to the untrained eye. Your plumber should be willing to walk you through the video and explain what they found. With high-res images, bright lighting, and self-leveling technology, you should get clear, steady views of the pipes that make up your plumbing system.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

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.

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.

Roto-Rooter does not charge by the hour, so the quote you get after your in-person consultation should cover the whole project. This includes the time it takes a technician to get to your house and the time it takes to complete the job. For context, a plumber will charge anywhere from $45 to $200 per hour, but you may also pay a service fee or flat fee.
