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.

Water leaking through your basement floor is a good sign of a clogged drain, but another sign of a clogged basement floor drain can include unpleasant odors coming from the drain. Also, hearing gurgling noises when water drains from the basement or having other plumbing fixtures (like toilets or other drains) backing up is a good indicator.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

Snaking a toilet is similar to clearing sinks and bathtubs, but there are unique circumstances where you’d have to drain, disassemble, and remove the toilet to fix the clog. For stubborn clogs in the toilet trap, a toilet auger—designed with a shorter cable and a protective plastic encasing—can navigate the tight bends and clear the clog without risking damage to the porcelain. 

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.
