How Do You Get Rid of Sewer Smell After A Sewage Backup?

Sewage backup is a common problem that can occur in any residential or commercial property, and it can cause significant damage, posing health risks, and leave an unpleasant odor that lingers long after the backup has been cleaned up. Cleanup is most effective when completed by a professional restoration company, and they will be able to help you get rid of any smelly odors that persist. A restoration company will understand the importance of eliminating sewer smell after a sewage backup. In this blog, we will share some of the steps we take to identify the source of the odor, remove it, deodorize the affected area, and conduct tests to ensure that the odor has been completely eliminated.

Cleaning Up After A Sewage Backup

Sewage backup can occur in any home or business. It can be caused by a variety of factors, including heavy rain, blocked pipes, or malfunctioning septic tanks. When sewage backs up, proper cleanup is the most important thing.  A proper cleanup will help eliminate any foul odors. Here is how we make sure the stench doesn’t linger.

Step 1: Identify the Source
The first step in getting rid of sewer smell after a sewage backup is to identify the source of the odor. In most cases, the smell is caused by bacteria and other microorganisms that thrive in the sewage. These microorganisms release gasses that create the foul odor. Our restoration team will perform a thorough inspection of the affected area to determine where the odor is coming from. We'll also check for any other potential sources of odor, such as mold or water damage, that could be contributing to the problem.

Step 2: Remove the Source
Once we've identified the source of the odor, the next step is to remove it. This may involve removing contaminated materials, such as carpet, furniture, or drywall, that cannot be salvaged. We'll also use specialized cleaning products and equipment to disinfect the affected area and eliminate any remaining bacteria or other microorganisms that may be contributing to the odor.

Step 3: Deodorize the Area
After the source of the odor has been removed, the next step is to deodorize the area. Our restoration team will use a variety of specialized techniques to deodorize the affected area, depending on the severity of the odor and the type of materials involved. Some of the techniques we may use include:

  • Thermal fogging: This involves using a machine that heats up deodorizing chemicals and disperses them into the air. The chemicals bind to the odor molecules, neutralizing them and eliminating the smell.
  • Ozone treatment: This involves using an ozone generator to produce ozone, which reacts with the odor molecules and breaks them down into odorless compounds.
  • Air scrubbing: This involves using a machine that filters the air, removing odor molecules and other contaminants.

Step 4: Monitor and Test
After the deodorization process is complete, we'll monitor the affected area to ensure that the odor has been completely eliminated. We may also conduct air quality tests to confirm that the air is safe to breathe and that there are no remaining contaminants present.

Of course, the best way to avoid bad odors due to a sewage backup is to prevent sewage backup and protect your home. Here are some important to take preventative measures: 

  1. Avoid flushing anything except approved tissue products down the toilet, do not rinse hair down the bathroom sink, and do not dispose of grease or food scraps down the kitchen drain.
  2. Adopt a regular cleaning and maintenance schedule to keep your plumbing system functioning optimally.
  3. Install a backflow preventer and a sump pump alarm to alert you to sewage backups.
