Sewer Cleaning questions, answered by experts

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.

The type of clog in your sewer main determines the required cleaning method. Different types or methods of sewer main cleaning require various tools like chemicals, mechanical removal, or a combination of both. Some of the most common types of sewer main line cleaning include:

  • Minor debris removal: $100–$600

  • Tree root removal: $100–$1,000

  • Trenchless pipe repair: $60–$250 per linear foot

  • General line repairs: $1,000–$4,000

  • Full pipe replacement: $3,000–$25,000

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.

Professionals use augers, hydrojetting equipment, and cameras for precise clearing and inspection.

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.
