When you have mold, making the correct decisions right away is critical. Whether it’s mold in your home, school, place of work or apartment there are many factors to consider. Are you going to be involved in a Mold Lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need Post Mold Remediation Testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It’s important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages & property damages require different environmental tests to prove your case in court.

"The body was found during a police wellness check. CSI was called by the local police department to transport the body. Once that was done, the floorboards of the room where the deceased was located needed to be removed and a bio-hazard barrier applied to the room. All of the clothing, bedding, towels, mattresses, cloth-covered furniture, window treatments, etc. had to be removed from the entire house. Walls and remaining furniture had to be sanitized. Floorboards were replaced and new carpeting installed. The only reason I didn't give them an A on Punctuality is because the work took longer than I expected. Warning to make sure everything you want to keep is on their written list. I "lost" things I thought were on the list, but with the chaos of the death, etc. they never got onto the list."

SERVPRO of Evergreen Park / South Chicago City is a trusted leader in the restoration industry. We provide 24-hour emergency service and are dedicated to responding faster to any size disaster. With the training and expertise to handle your restoration and cleaning needs, we’re locally owned and operated and can respond immediately to your emergency.

"ServPro South brought in a team of 8 workers, who scrubbed the surfaces throughout the first floor with special soot removing chemicals: the ceiling, the walls, the furniture that had not melted, and even the 65 luggage-sized lockers--inside and out-- that we use for the Ujima Storage Project, which enables homeless youth to access safe storage options for their personal belongings. They also brought in 6 air cleaning machines, which vacuumed the air 24 hours a day for four days. When they started, the ceiling was black from all the smoke that had collected there. When they left, it was white! The air smelled fresh and clean with no trace there had ever been a fire. Thanks to ServPro, we were able to partially re-open the shelter just in time for the 14 day, sub-zero cold snap that we had in early January 2018, and we were able to provide the youth a safe, warm bed, a restroom and meals."

FAQs for biohazard remediation projects in Marengo, IL

There are several instances where household biohazard cleanup would be needed. All in all, anytime an event can potentially expose people to chemicals, pathogens, or viruses, a biohazard cleanup company must be called. These events can include:

  • Sewage backup

  • Unattended death or crime scene after death

  • Virus decontamination

  • Medical waste disposal 

  • Animal waste disposal 

  • Odor control   

  • Hazardous chemical removal

The cost of biohazard cleanup averages between $3,000 and $5,000 for most homeowners. Some services, like sanitizing high-traffic areas or sanitizing surfaces from a virus, cost closer to $1,500. However, other circumstances, like the extensive cleanup after a major sewer backup, could cost as much as $25,000. 

While a biohazard cleanup sounds like a scary process, knowing what to expect can help ease your concerns and set you up for success. It’s good to note that more than one professional might be needed depending on your situation, but that will be determined during the assessment. What you can expect during a home biohazard cleanup is the following:

  • Assessment: The first step in this process is for a biohazard cleanup professional to assess the damage. They create a report that includes the biohazard safety level, the needed damage cleanup, and the time it should take to complete the project. 

  • Setup: The cleanup professional prepares the site to prevent cross-contamination and reduce toxicity risk. This process can include tarping and creating decontamination zones. 

  • Removal of surface contamination: Any contaminated materials are removed from the area, starting with large materials followed by small ones. The professional can assess any floor-related damage once everything is removed from the site. 

  • Salvaging items: The biohazard cleanup professionals assess which items can be saved and which are contaminated beyond the point of saving. Those deemed unsafe will be disposed of immediately. 

  • Waste disposal: The next step is carefully disposing of the hazardous waste. Your professional will place the contaminated items in specific containers to keep the contamination from spreading.   

  • Disinfection: The house will be disinfected and odor-neutralized. Even more minor details, like light switches and bulbs, will be disinfected so that they do not recontaminate the area in the future. 

  • Restoration: Once the decontamination is complete, the last step is to restore the home. This includes repairing the damage to flooring, walls, or even the home's foundation.  

Most homeowner’s insurance policies can help cover the cost of biohazard cleanings for specific events. Biohazard events like unattended death, infectious disease, and medical emergency are generally covered, as are flooring and drywall repairs. It’s best to check with your insurance company to see what is specifically covered.

One of the best ways to prepare for a home biohazard cleanup is not to touch anything. Do not remove belongings, even if they are of value or importance, from the area as they are likely contaminated. It’s essential not to use any cleaning products of your own, as the cleaning company will be using chemicals that could interact with your products. 

One thing you can do to prepare is take pictures of your space and belongings that need to be cleaned, especially if you plan on filing a claim with your insurance company. In addition, take time to make a list of items that are valuable, sentimental, or otherwise important. The cleanup company must evaluate these belongings to make sure they are safe.
