"Great! John, the owner was super helpful and nice on the phone. Eased all our concerns. The crew, Phil and Tim, showed up right on time and were able to locate the service caps in the lawn in 10 minutes. They showed me clearly how full the tanks were and clearly explained the problem and the solution. The prices quoted were very fair and there were no surprises. It took around 90 minutes. The job was all done outdoors and when they left you would never know it was done. Very neat and professional. The odors, etc we had were gone and we noticed the drains all flowing more freely. Exactly as they said. So glad we had this done before it became a serious and ugly problem inside the house. We highly recommend Priority Cesspool Sewer and Drain. Thank you!"

"Okay. So there was a problem with the sewage pump, water in tub and toilet would not go down. The first person to show up after contacting Home Advisor was Mikey from BestFlo. Panicked, I said okay, you can do the job. Awhile later he said it was fixed, and walked away following the repair leaving the area a watery mess with the burnt out equipment, and all the lights on. (I?m not going to even mention the dirt tracked into my house from his shoes.) Honestly I was so angry and distraught about the situation (btw - strictly forbidden disposable wipes were the cause of this $1K expensive repair job) that shortly afterward I went to bed, leaving the cleanup to others in the home. The next morning after taking a shower the toilet would not flush properly, and there was overflowing water [AGAIN] from the replaced sewage pump. I called Sunday 4/19 and was told that someone would appear Monday 4/20 btwn 9:30 - 10:30.am. At 10:40 Mikey reappeared, went to examine the area, quickly adjusted something with the plugs, the system restarted, the toilet automatically flushed, and everything appeared fine. No charge for the revisit. The replaced equipment is guaranteed for only a year. :-( In summary, you can use this company if you wish; just read my review once or twice again before making your choice. Needless to say, my review is quite less than enthusiastic."

"We returned from an out-of state Thanksgiving celebration only to find a flooded basement due to a heavily clogged sewer line. We were panicking but Louie responded to our emergency promptly. We found him to be extremely knowledgeable and very professional. He took time to explain the problem and what was needed to solve it and answered all of our questions clearly. It required extreme physical effort for him to clear the sewer drain and it wasn't a pleasant job. But he never gave up until it was done. In doing this he avoided bringing in additional equipment which would add to our cost. His price was fair and he gave us helpful suggestions on how to proceed to the next step in restoring our basement. We are very grateful that we came across him during this emergency and wouldn't hesitate to recommend him to others."

"The two gentlemen from All Island Sewer and Drain arrived promptly, assessed the condition of my sewer main and methodically cleared out the pipe. They provided excellent craftsmanship and service by integrating modern technology (high quality video imaging) with state of the art “electric snake” to clear the blockage. They also identified the source of the problem (a partially ruptured sewer pipe under my lawn) which will be addressed at a later date. Their fees were also very reasonable. The work area was left in pristine condition and I will definitely be calling them back, to make the permanent repairs when I’m ready…truly a first class organization. Thank you also to Dominic for the quick response…my family is grateful 🙏🏽."

"DEFINITELY WORTGY OF A RATING OF 5 STARS ! I am a small business owner that ran into an issue on the job site! We called the Owner AJ directly at 6:00 PM to help our team out while on site of a cleaning job.. a shower/tub combo at a customers house was clogged & we couldnâ t get it to go down no matter what we did ! This company was highly recommended on a local Facebook group weâ re apart of, so we decided to give them a call.. all the whole knowing we would probably get a no sorry we cannot help you at this time type of response because of how late it already was and knowing it would cost a fortune because of it being an emergency.. but we tried it anyway! The owner himself came within 1 hour of the first phone call, he fixed the issue & surprisingly the cost was absolutely no where near what I was expecting! I give 5 stars hands down to this company based off of my own experience! They are very knowledgeable, reasonably priced, reliable, quick and efficient and super kind as well as very good at explaining what the issue is and how to fix it in terms the consumer can understandâ ¦ if I could give more I would! I definitely did not feel pressured or taken advantage of either, which as a woman is always a scare! The owner himself is very friendly, honest & knowledgeable! !! I will definitely be using them again as well recommending them to anyone I can !!!"

Sewer Cleaning FAQs, answered by experts

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

Costs vary by severity and access requirements. Typical pricing ranges from $100 to $350, increasing with complexity or for emergency services.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

Costs range from $200 to $600, depending on the severity of the blockage and access difficulty.
