"We recently had a service call by Mid-Westchester Sewer & Drain. Initially, the technicians were Gustavo and Mekhi and, when additional equipment was required, the owner of the service, Vinny, arrived with it. Over the course of several hours they snaked the outside water pipes from both ends, viewed the interior of the lines with a cable-mounted camera, and then flushed the lines with high-pressure water. They were prepared, professional, efficient, friendly and competent and we would recommend them without reservation."

"We had banging & whistling noise from steam radiator pipes and the very old (but good) oil boiler during very cold days. He diagnosed what needed to be done. It was a serious amount of work, replacing a very old, badly corroded pipes and regular cleaning of the boiler. We could have had serious flooding if this had not been noticed and replaced it. Unlike other person's diagnosis, he knew exactly what needed to be done. It took three days to finish everything. He was very professional, experienced and very thorough and we are so relieved to have oil boiler /steam radiator running smoothly. Keeping an old house is an on-going job and it was so nice to have someone work very professionally. He offered warranty as well, so we know he is there for us should there be any issues. Recommend him highly!"

Sewer Cleaning FAQs, answered by experts

Outdoor plumbing issues are no less serious or urgent to fix than interior plumbing problems. These problems may require excavation and lawn repair due to the plumbing often being buried underground. The most common outside plumbing problems include:

  • Clogged landscape drainage: $200–$1,000

  • Clogged sewer lines: $60–$250 per linear foot

  • Corroded or rusted pipes: $1,500–$15,000+

  • Leaking drain lines: $200–$1,000

  • Leaking water mains: $300–$4,000+

  • Septic system failure: $600–$3,000+

  • Tree roots in pipes: $200–$1,000

  • Well pump failure: $350–$1,500

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

It's advisable to have your sewer line inspected every three to five years to ensure its proper functioning and detect any potential issues early on. However, the frequency of inspections can vary based on factors such as the age of your sewer system, the type of pipes used, and your property's location. If you notice any warning signs like slow drains, foul odors, or sewage backups, it's essential to schedule an inspection promptly, regardless of the regular maintenance schedule. 

It is generally safe to stay in a house that smells like sewage for a short time, but you should get the problem fixed as soon as possible. While the level of sewer gas is usually low enough to only cause minor symptoms, prolonged inhalation can lead to headaches, nausea, or respiratory irritation. High levels of gas exposure can be more dangerous, and high concentrations of methane—a component of sewer gas—can pose an explosion risk in enclosed spaces. If you smell sewer gas in your home, ventilate the area and call a professional to locate, assess, and fix the problem, as it will not go away on its own.

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.
