Bio-One of DC decontamination and biohazard cleaning services


Washington DCMold Remediation

Biohazards and hoarding can create an environment for mold growth. There's no need to risk removing it yourself. Let Bio-One of DC remediate it for you.

You called the right 
team for the job.

Quick Action

It only takes 24-48 hours for mold to colonize. All that’s needed is organic material and water. Typically, excess moisture from floods, leaks, or poor ventilation will do the trick.

Mold is a natural substance that also loves warm, indoor environments. The fungus can get in through doors, windows, HVAC systems, etc. and usually plants itself where no one will see it:

  • Attics and crawl spaces
  • Under sinks
  • Near washer and dryer hookups

Mold can be hazardous. The impacted areas will need to be treated by a professional. If not removed properly, certain health risks may follow:

  • Respiratory complications
  • Skin irritation
  • Severe allergic reaction

Whether it’s removing surface-level spores or tearing down and reconstructing larger areas, it should be done professionally.

Quick actions once the mold is noticed will prevent a lot of damage. We can save you money on damages and the time it would take to repair them. 

Address the Source

Removal of the mold will only get you so far. It came in and grew somehow. At Bio-One, we address the source from which the mold came.

Any highly contaminated items will be disposed of. Our proper containment system will prevent any cross-contamination. However, mold will also be prevented from entering by the same means.

If you’re not addressing the problem, how much help can removal actually be? It’s sure to come back within 24-48 hours.

The Bio-One team did an amazing job cleaning up a hoarding job for me. Within 24 hours of calling they were at the door ready to go. Prices are fair and customer service is beyond top notch. I wouldn’t use anyone else ever again for a cleanup job big or small.

I called Bio-One spoke with Tiny regarding a dear friend's residence without hesitation he explained his company process and said not to worry they could make a difference. I had to write an endorsement for the work this team of men have done; to endure such an undertaking with compassion and encouragement all while diligently purging three levels within the home. Afterwards coming back and sanitizing each area. Not once did I see a look of disgust. Total professionalism exhibited. Tony gave recommendations to continue maintaining a more healthy living environment. If you know of someone in need of this type of service be a friend provide the support and call Bio-One (Tony) will provide courteous professional service. On behalf of my dear friend Thank you so much. Continue doing exceedingly bless work. Ms.G & Robert

BioOne service did an awesome job. In the middle of my critical crisis. I had to make a call to a crime cleaner service. BioOne was one of the top three people to contact. Once I made the called. I explained to him what happen. Tony was extremely professional, kind and courteous. I had to call him a few times. Not once did he get irritated with me. Tony explained the process step by step which help me understand more of what was about to take place. A few hours later he showed up with his technician. They both did an excellent job. I highly recommend BioOne services for all your professional needs.

Besides the extraordinary customer service and professionalism, I am most grateful for Jermaine’s and Tony’s sympathetic manner. The entire Bio-One team went above and beyond to support our condominium community while managing an outrageous hoarding clean-out. Jermaine was in regular contact me and showed tremendous patience with the hovering mother still processing the horrific contaminated scene. Jermaine made two courtesy visits to accommodate the mother’s need to go through items and move heavy objects. Jermaine provided extra disinfectant, treated the area with an anti-COVID product and left an air purifier overnight to appease my smell sensitivity - all free of charge! I received 3 bids and Tony’s estimate was a significantly better value. I hope the universe responds in kind to their generosity - I HEART BIO-ONE!
