"They called quickly to determine the problem and they set the appointment for the same day. The problem was quickly diagnosed, and instead of charging us for unneeded parts, they took care of the problem with a simple cleaning of some sensors and adjusting the thermocouple. They then took the time to explain the best way to keep the furnace running and to prevent further service calls. That is what customer service is all about."

Sewer Cleaning FAQs, answered by experts

When hiring a sewer line company, you need to consider more than just the quoted price. Make sure to check that the company or contractor is licensed, certified, and insured to protect you both. Check for positive reviews, and you can even request references for extra peace of mind. 

To find the best contractor, you might also want to consider how long the company has been in business doing sewer line cleaning and if they’ve won any industry awards for their work and service. Review potential contracts closely, and look for transparent pricing.

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.

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

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.

There is conflicting advice on whether to leave a baking soda and vinegar mixture in a drain overnight. Some sources suggest it can be effective for tough clogs, recommending that you flush the drain with warm water in the morning as part of a monthly cleaning routine. However, other experts advise against leaving the mixture in for extended periods, as its caustic nature could corrode drainpipes if used too often or left in for too long.
