"This sewer line project required a few days from camera work to excavation, replacement of pipe, installation of an additional clean-out, backfill and clean up of not only our excavation area, but consideration of our neighbor's shrub close to the work area. Chris and Ryne, the company supervisors/representatives, provided knowledgable and detailed information prior to, during and upon completion of the work. They were professional and exceptionally courteous in person, to our neighbors, and over the phone. This was especially important as one of us was out of state during the project, and the other had to leave early for another trip out of state. That meant the final inspections and details were handled by the guys for us. Excellent work, start to finish!"

"Our downstairs toilet, shower and sinks were backing up. We called Drain Pro and they arrived shortly after to look at the problem. They scoped the sewer line with a camera and found a big blockage that was caused by roots. They were able to clear the blockage. Everything is now working great. We will have them back in the future to re pipe the area where the roots have started coming thru. This company is great!!!"

"Pipers contacted us by phone immediately after we submitted a repair request on Labor Day late morning for a clogged sewer line. We set up an appointment for early evening, at which time I mentioned we had intended to celebrate family birthdays that evening. About an hour later Pipers called and said they adjusted their schedule so they could arrive mid-afternoon, which they did. The back-up was cleared and we were so grateful to be able to join our family that evening. Pipers had to remove and reinstall the basement toilet. They cleaned up the area after the work was completed (the bathroom looked better than when they arrived). A great ending to what was a not so great beginning to Labor Day. We will definitely use Pipers for the more extensive work that needs to be done."

"I had a clogged drain that no amount of plunging could get rid of. I called several companies. I initially went with Mr Rooter because they were the only ones that could make it out that same day. Glad I did. The technician was very pleasant and he took his time to explain all the steps he was doing and let me watch as he put a camera down the drain and showed me on the screen where the clog was and all the build-up in the pipes. He then brought in a high pressure washer and I watched on the screen as he cleaned the pipes all the way down to where it joined up with the main sewer line. I initally thought the estimate was a little high, but not after watching all that they (his supervisor also showed up after an hour to help out) did."

"Diagnostician/Estimator and Plumbing team were just excellent. Sewer work and team very good, but also very pricey. Repairs on system were well done - crawlspace access area was damaged to extract the old sewage tank. Damage is still being repaired by homeowner. Harts rebated some cost to cover access damage. All Harts team members were fully vaccinated, wore masks, and were great to work with. Harts completed work within 1 day within quoted costs. New sewer pump alarm system system malfunctioned right after the install was finished - Harts sent a repair tech out to fix it on next day - excellent service - fixed the twisted tank float problem - no charge. Building inspector noticed new sump pump was tilted and alarm wiring was not properly affixed to the house - minor issues, I would hire Harts again but negotiate hours and pricing ."

"Very happy with CTC Lights work. They decommissioned my failing septic system and connected me to SCWSD sewer. Coty was very knowledgeable of all the legal requirements and kept me informed thru the whole process. They were very respectful of my landscaping and left it in better shape than before."

"Hot water tank went out. Platinum came out same day, and installed a tankless unit, and just in a few hours we are back to having hot water again. Very professional, friendly, and did a great job cleaning up, and taking away the mess. Best of all, these guys know what they re doing...will use them again in the future for any other plumbing project we have."

Sewer Cleaning FAQs, answered by experts

A sewer line should be cleaned at least once every 18 to 22 months. The process takes about 30 minutes or up to 5 hours, depending on the size of the line, how easy it is to access, and how long it’s been since the previous cleaning. If your sewer line hasn’t been cleaned in a couple of years or you don’t even know the last time it’s been cleaned, it’s time to call a pro.

Professional tools include drain snakes, hydro jets, cameras for line inspection, and enzymatic or chemical cleaners for dissolution.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

In most states, companies that perform sewer cleaning services don’t need specific licensing, but you should always ensure you hire a licensed and certified plumber to get the work done. You can use our state licensing tool to check whether the potential sewer cleaning company holds a plumber’s certification and license. Hiring a certified sewer cleaning services guarantees that the work will be done safely, there won’t be additional damage done to your home, and the problem will be fixed.

Yes. Sewer cameras are invaluable tools that can help pros safely diagnose problems with your septic system. Without a camera to look into your system, septic issue diagnoses would be a combination of guessing and past experience. However, a camera can help confirm ideas that your pro may already have about what’s wrong.
