Chester CountyCrime Scene Cleanup

Crime scenes are typically unexpected and never welcomed. When incidents strike, you can count on Bio-One of Chester County to clean up the scene discreetly and professionally.

You called the right 
team for the job.

Competent Crew

Incidents involving a crime scene can be overwhelming and very stressful. At Bio-One of Chester County, we understand this. Our team knows to be discreet and respectful. They understand the magnitude of each situation and will approach it as such. 

Not only will we understand the situation, but we’ll be able to help clean no matter the circumstances. As experts in the field of cleaning, each technician on our crew:

  • Is trained and certified to clean crime scenes
  • Follows all OSHA guidelines
  • Loves the work they do for the community

Our expertise in materials and cleaning techniques means there’s no job too big for us. Once the authorities leave, we’re the first on the scene and we stay until it’s finished.

We’re also available 24/7 to answer any call. You’ll never be left waiting on us. We’ve been a part of the Exton, PA  community for many years now and are proud to help keep it clean. 

Site Restoration

Site restoration is another perk of working with Bio-One. Using advanced technology, our crews can restore your site to its original state. This includes getting rid of odors, disposing of biohazardous material, etc. There’s no limit to what we can’t do. You can quote me, Thomas Gervasio, owner of Bio-One of Chester County on that.

For many people, this is an emotionally taxing time when the focus needs to be elsewhere. You shouldn’t feel responsible to clean up. In some cases, it could even be dangerous if done incorrectly. Let us take care of it so you can focus on what matters.

What an amazing experience. A member of my family has struggled with hoarding disorder for many years. It wasn’t until I came by to visit that I found that it had progressed to the point where her house was extremely dangerous and hardly livable—bags piled to the ceiling in every room, and every desk drawer and cabinet filled to the brim. Some windows were inaccessible and had not been opened in years. I called Bio One to inquire and the owner, Tom, thoroughly answered all my questions and walked me through the process and gave me cost estimates. Over the course of a few days, I watched Tom and his very respectful cleaning team transform her house from a garbage dump into a beautiful home. Bio One literally changed our lives for the better. I highly recommend them. They’re really the absolute best!!

I highly recommend Tom and Bio-One. He was amazing from the first phone call. He handed a delicate situation for us and was very helpful for further recommendations. He was prompt and helpful in resolving the problems. We were in town for only a few days and he was quick to help us resolve all. He went the extra mile and did a great job! Professional, accommodating and very helpful in a stressful situation.

Bio one Chester county Just recently did a job for me. I had dogs that Peed on a concrete floor in the basement. Several other companies were not able to guarantee they could get the smell out. Bio one Was able to. They Took the smell out and were reasonably priced punctual and very friendly. I would definitely recommend Bio-one if you have any type of pet odor or any odor in general.

First time home owners here. We decided to take the safe route before moving into the property and get the house sanitize due to covid 19. I did a Google search for the top best covid cleaning companies and found Bio-One Chester County.

This is my first experience with Bio-One and I can not say enough great things about them. Prompt, nice, hard workers and very detailed!

Tom and his team promptly responded to my need for a home cleaning after a COVID quarantine. They were extremely accommodating despite my last-minute request. They made it to my house within a day of contacting them and kept me updated the entire time. Once at my house, they worked efficiently and even offered to extend their services to sanitize my car. They went above and beyond for me and also happen to be some of the friendliest people I've come across. I would highly recommend Tom and Bio-One!
