The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

Your sewer pro will take about an hour to complete your sewer line camera inspection. However, if your home does not have cleanout access and the pro needs to remove the toilet to access the sewer line, the time to completion will take longer. Note that this estimated time does not include the time for repair, drain cleaning, or any other services you may need. 

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

Depending on the home, wastewater either goes into a septic tank and seeps back into the backyard or is sent via sewer system to a local sewage-treatment plant. Septic systems naturally separate different components of the waste so that it can naturally and safely disperse it. They are usually reserved for homes not served by a municipal sewage department (like rural homes). A treatment plant, on the other hand, speeds up that process through screening and purification.
