Sewer Cleaning FAQs, answered by experts

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.

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.

Your home has a few telltale signs of a sewer line problem. If you notice multiple plumbing fixtures (toilet, sink, or shower drains) appear to be clogged, call a plumber ASAP. Also, if water appears in the tub or shower when you flush the toilet, you likely have a sewer line issue. A sulfur (rotten eggs) smell and bubbling or gurgling noises at the drain also warrant a check. And keep your eyes peeled for changes to the yard, such as a new indentation or mysteriously soggy grass.
