We are locally based, indoor air quality consultants who test the air and dust to find the sources of building problems that can cause health symptoms. We do not use subcontractors. Jeffrey C. May, Principal Scientist, and Connie L. May, Office Manager, work together as a team and are co-authors of four books on indoor air quality, published by The Johns Hopkins University Press. Jeff is a Certified Indoor Air Quality Professional (AEE) and a Certified Mold Inspector and Assessor (ESA). Fees are job based.

"If it would be possible I could give more than 5 stars. Jeff and Connie are very nice people and incredibly knowlegable specialists. They went above and beyond, conducting inspection of our house. I invited them because of presence of mold and odors. The house was thoroughly inspected not only for those problems we concerned of, but for all other possible hazards. Jeff and Connie spent as much time at our house as it was needed to complete all the aspects of required inspection. Each room, even every little space, furnace, AC unit, stove, refrigerator were inspected. Shortly after appointment I got detailed reports with photos and multiple very helpful recommendations. Now we know what exactly should be done in the house and outside in order to eliminate negative issues found by Jeff who is an expert in all aspects, related to different systems of house. Jeff and Connie are very kind and intelligent people. It was a real pleasure to spend several hours with them at our house. This appointment was life-changing for us. I highly recommend May Idoor Air Inspections to all who would like to make sure that environment of living places is safe."

Biohazard remediation services FAQs

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.
