Sewer Cleaning FAQs, answered by experts

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.

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.

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.

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

When hiring a sewer line company, you need to consider more than just the quoted price. Make sure to check that the company or contractor is licensed, certified, and insured to protect you both. Check for positive reviews, and you can even request references for extra peace of mind. 

To find the best contractor, you might also want to consider how long the company has been in business doing sewer line cleaning and if they’ve won any industry awards for their work and service. Review potential contracts closely, and look for transparent pricing.
