"I called and they came out the same day.  They arrived a little later than expected, but they did call to let me know they were running late.  Steve and his helper were clean and very friendly.  I would use them again and give their number to my friends."

Sewer Cleaning FAQs, answered by experts

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.

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.

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.

In most cases, drain cleaners will not clear a clogged sewer line, and they’re likely to damage your plumbing. Sewer lines are several inches wide, meaning any material that clogs it will need to be large. Drain cleaner can work on small clogs, but it usually won’t clear a larger one in a sewer main. Drain cleaners can also easily damage and corrode your plumbing with prolonged contact, and a clog will keep the cleaner in contact with the pipes for an extended period. Hire a professional sewer cleaner instead for a safe fix.
