Proudly serving Southeastern Wisconsin, I'm Scott Nelson, I am the owner-operator-inspectors for Criterion Home Inspectors LLC. We take pride in our work & do whatever we can to help home owners insure they maximize the return on their investment. The cost of each job is determined by the square footage of the area to be inspected. Travel charges are not incurred. Visit our website for more testimonials.

"When I started working real-estate for family and friends in the Eastern part of Wisconsin, a dear friend and referral partner realtor, of mine, recommended Criterion Home Inspectors. I met Scott and was immediately impressed. I had outstanding inspectors back in South Central Wisconsin that had set the bar for HIGH expectations. Scott hit that bar and I've never looked back. Anytime my other inspectors are on vacation, I always give Scott for the opportunity to come over to do the inspection because I know he is going to have integrity, be straightforward, doesn't the report to cover his butt, not an alarmist, and definitely NOT a 'dollar' store inspector. He explains things in layman's terms to the buyers,(and sellers for pre sale inspections) answers all their questions. And if he doesn't know something, he says so and that he will find out, and DOES. Just a great guy and resource for new buyers and seasoned realtors. We highly recommend Scott!!"

"The project went very well! Mike is terrific. The crew came as scheduled. Explained what they would be doing and did a nice job.The first part of the project involved trenching the basement floor along the three walls. This was the dusty and loudest part of the work since they use electric jack hammers. Make sure you cover everything. They did a great job cleaning up the area they worked in but you will still have dust. We had a minor problem and came to a mutual agreement for solution. Nice people to work with, great job!"

FAQs for biohazard remediation projects in Jefferson, WI

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.
