About Us

I was a dunderhead and thew a package of mothballs into the attic to evict squirrels. It evicted the squirrels but came close to evicting me. I needed to have the mothballs removed from my attic or else move to a hotel. Matt Gregg took care of the problem within minutes. He arrived exactly on time, followed the instructions as to how to access my house from the alley, and greeted me with a smiling handshake, which in the era of Covid has become a luxury. The whole process took 30 minutes. Matt showed me the bucket of attic mothballs and answered my prayers, and believe me I was praying. Note to self: NEVER throw mothballs into the attic. Bio-One is a big company that usually does horrible jobs like crime scene cleanup, so I was incredibly lucky they had the time to restore my life in my house. Thank you Matt Gregg, and thank you Bio-One.

Positive: Professionalism, Punctuality, Quality, Responsiveness My Aunt has had a terrible issue with hoarding and after 7 years we finally were able to convince her to let someone deal with it. Mark and his Charity were phenomenal in dealing with her and understanding the challenges of dealing with someone who is dealing with a mental health issue. They were very professional and accommodating and supportive during the process and for the most part took care of everything that we were dealing with. I recommend them for any cleaning needs! Services: Standard cleaning, Deep clean

Positive: Professionalism, Punctuality, Quality, Responsiveness My dad was in the hospital so they came and took care of his home so I could take care of them. Thank you all so much. Service: Deep

They came in and helped me de-clutter and clean up. They were so fast and amazing and patient with me. What would have taken me months, they did in a day! Could not recommend them enough!! Thanks for your help, Bio-one!!

Andrew and his team went above and beyond to take care of our multifamily building. Andrew was very communicative and supportive as we made it through an unexpected sewer clean up. I'll be forever grateful for the Bio-One's quick response. Since I managed the process from another state, flawless communication was a must! Andrew provided exactly that! Top tier service!

Bio-One DC was very responsive to my request and questions. They not only confirmed they could handle removing all the empty boxes and other things that had piled up in an apartment during the pandemic, but could do some deep cleaning too. They offered a work date for the next day, but since it was during the weekend and was sooner than I could accommodate, they schedule it when it was convenient for me. There was excellent communication before and during the work. Jermaine, Larnell, and River were very kind about the situation and very helpful in getting the job done quickly. Thank you. If you are in DC area, especially if you need to schedule something quickly, Bio-One is recommended.

After struggling to get someone to help us clean out a cluttered home, Mark was referred to us by a satisfied customer. He was very responsive and was able to come right out and give us a quote. They arrived promptly when they were scheduled. The job was done in the 2 days that were quoted. Most importantly, the entire crew was very understanding of the emotional needs surrounding a clean out of this kind. We appreciate all of the care, compassion, and patience given by Mark, Charity, and Gabriel!! We couldn't have done it without you!!! I would definitely use them again or recommend them to anyone!!! Sincerely - Bobby

I was very happy with the work done in my grandmother's building. The men that came to work were a blessing to me and my family. Very satisfied and would use there services again. Luis Gonzalez

I was in the middle of remodeling my place when the rains in May showed I had problems in my roof. Water started to run down from the ceiling on the walls. Making puddles on the floor. My insurance (Farmers Insurance) recommended I hired a company to read the mosture on the walls. They gave me the name of two companies, but after reading their reviews I decided to look for other companies. I found Bio-One and gave tem a call. Armond answered the phone and the next day him and another worker inspected the house and by that evening I had a report to send to my insurance. Unfortunately, they found lots of moisture. We open the walls and found some mold. The next day Armond was there for three consecutive days cleaning and removing the mold. When I went to inspect the job I was very pleased with the results of his work. Every day he kept me informed, and took photos of the progress. I recommend Bio-one of Oceanside highly. They are on time and, they communicated on a daily basis, and are very professional.
