"Rooting ended up being difficult. Worker hung in there until he solved the problem. Methodicial in approaching the problem, communicated well, clean. Showed up on time. Neighbors gave recommendations, but none of them were available. My wife entered information through Angies List to find someone and I received a call fairly quickly to my surprise. This experience was well worth the value. I will use Aurora Sewer Cleaning again."

"The technician was very thorough in checking to see if any subflooring had been damaged by the leak, and he explained in detail what needed to be done and gave me an estimate before starting work. I was very pleased by his solving the problem quickly. I was also pleased that the company contacted me about its plans and by the technician asking me if he could come earlier than he was scheduled as he had finished another job faster than expected. I really wanted my problem fixed quickly, so I was pleased by this request."

"Repair guy was nice and did good work. Was not told ahead of time that I would need to pay 408 dollars for essentially hooking up a wet vac to the end of a pipe and turning it on for thirty seconds Expected to pay $200 Actual payment was $493 Line codes from the invoice S-Service Call $85.00 S-Blow Out Condensate Drain $408.00 DESCRIPTION OF WORK / RECOMMENDATIONS from vendor Condensate pvc drain clogged with sludge & slime. Cleared condensate drain with nitrogen & vacuum. Unit draining properly after repair. 0ppm co reading. No gas leaks found. Customer recently had a cc completed. All ok at departure. Recommendation is that if you need this service performed is to get a quote in writing from the vendor ahead of time or just get a shop vac and do it yourself. Will not recommend although would like to hear vendor response as to how this poor customer experience could work better. (UPDATE): The Vendor has reached out to try and mitigate the cost and is much appreciated."

"There was a guy here for about 10 days re-piping my house.  They managed to not rip through my floors or ceilings to get the job done, I was impressed.  Patrick, the owner, stopped by a few times also to make sure the work was being completed.  I highly recommend them."

FAQs for drain clog or blockage clearing projects in Seneca, IL

Snaking a simple clog near a tub, toilet, or sink often takes about five minutes. Deeper blockages along the main line can stretch the job to a few hours because the pro must feed extra cable and may need a camera to confirm the pipe is clear. Either way, specialized tools help pros work quickly and keep your drains running for the long haul.

Aggressive snaking can scratch pipes, push debris deeper, or even crack older lines. That risk is low with an experienced plumber who matches the cable size to the pipe and eases the snake through bends instead of forcing it. If you’re unsure of your technique—or your pipes are already fragile—calling a licensed pro is the safest, and often cheapest, move.

Start with simple barriers: mesh screens on every tub, shower, and sink keep hair, food bits, and jewelry out of the pipes. Skip harsh chemicals; a monthly flush with hot (not boiling) water clears light buildup without damaging plastic lines. Finally, practice smart disposal—no grease, wipes, or kitty litter down the drain—and schedule routine cleanings if you have older plumbing.

Roto‑Rooter typically charges a flat $160 to $450 for standard snaking, which may include a quick sewer inspection and basic clean‑out. Exact pricing depends on the clog’s location and complexity. Repairs or part replacements fall outside that flat fee, so ask for a line‑item estimate if your tech spots broken pipe sections or recommends additional work.

Most liquid cleaners rely on caustic chemicals that eat through hair and grime—but they also erode metal and even some plastics over time. Repeated use strips protective pipe coatings and can leave you with leaks or premature failures. If hot water or a plunger doesn’t help, call a plumber for mechanical removal instead of pouring more chemicals down the line.
