"We have an older home with older ductwork. We had Spencer and Brayton out and they cleaned and sealed our ductwork. They did a great job. Professional, great communication, attention to detail. They reduced our air leakage by 86%. We noticed an immediate difference in improved airflow, our cold spots are no longer cold spots. Thanks!"

Sewer Cleaning FAQs, answered by experts

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

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. 

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

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.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.
