DenverTeargas Cleanup

Teargas residue doesn’t clean itself and takes months to subside if not properly removed. Although rarely fatal, many health risks arise from the residue. Let us clean it for you to avoid further complications.

You called the right 
team for the job.

Teargas is tricky stuff. Unlike other substances, it doesn’t just fade away. It takes months for the effects to subside.

Action must be taken. However, because everything is coated in the residue, cross contamination is likely. Professionals are recommended when dealing with teargas.

Cleaning Technology

Using the newest technology available, we can stay ahead of potential problems caused by this agent. By properly removing any hazardous residue and preventing cross contamination, no harm will be done.

Regardless of a personal or business setting, we are trained and certified for this very scenario. 

Health Risks

Exposure to teargas prompts many health risks. Skin irritation is commonly reported immediately after exposure. The longer the exposure, the more serious the problem:

  • Respiratory issues
  • Motor control loss
  • Heart damage
  • Liver damage

With an agent such as teargas, it’s important to act quickly. We make it our job to eliminate the risk of long-term exposure for you.

Community Outreach

We’ve been a part of the Littleton, CO community for many years now and are proud to help keep it clean and safe. We strive to make a difference in your lives.

The team helped my family member tame two years of long-Covid clutter in two days. From our first contact with Gregg to the end of the process, we were treated with dignity and understanding. Our only regret is that we didn't call sooner!

Bio-One made a very difficult situation much easier. A relative had a communicable disease and passed away in the house but was not discovered for some days. Bio-One not only cleaned and sanitized all surfaces but also removed carpeting. Since hoarding was a problem, they helped with saving documents and valuables and disposing of the rest. Their charges were reasonable and they helped with the insurance. They solved in a few days a problem that would have take my family weeks deal with.

Gregg and the cleanup team assigned were kind, considerate, and efficient. A relative had died and had not been discovered for several days. We appreciated the timely response and efficient removal of contaminated materials. Their approach made a terrible situation as quick and simple as possible.

Most helpful and thoughtful company! I called to ask for an estimate on getting a meth test done on my recovered stolen vehicle and the owners were so knowledgeable and kind! They gave me advice on the steps to take before getting the test done as to not waste my time or money on the testing. They were so compassionate and caring! HIGHLY RECOMMEND THIS COMPANY! :)

We are renting a house that was previously occupied by hoarders, so I contacted Gregg and his team at Bio-One to come out and look at the property. To my delight and surprise, Gregg was open and honest and let us know that his services were probably not going to be the most cost efficient for our needs - he recommended another cleaner and was honest about saving us hundreds, if not thousands, of dollars. While I didn't use Bio-One's services, I would recommend them 100 times over for their excellent customer service and best business practices!
