Gross Filth Cleaning

Gross filth can be difficult and dangerous to clean, as it often contains biohazardous waste. We have the training to remain safe and remove it all. Don’t risk lingering diseases. Let the professionals handle it.

You called the right 
ones for the job.

Bacteria, viruses, and mold are all harmful biohazards that need to be treated professionally. If left alone, each problem progressively becomes worse. At Bio-One, our highly-skilled technicians are trained to go in and remediate any problem of this sort.  

Bacteria & Viruses

We’re surrounded by bacteria everyday. We just can’t see it. Normal exposure is okay, but some forms can be dangerous (Covid-19).

We’re available 24/7 to sanitize and disinfect anything you can think of. Armed with knowledge of the proper products and procedures, we are sure to help alleviate the issue.

Mold

Organic material and water are all that’s needed for this toxic substance to grow. Therefore, mold can pop up anywhere and typically starts in non-visible sites.

We have the proper training to find and eradicate all fungus. Whether that means tearing out and reconstructing areas or simply removing surface level spores, we get the job done. 

Our crews are passionate about their work and truly care for each client. The ultimate goal is to help each person live in a comfortable, safe environment. That is something we can provide.

Bio-One Hoarding is ready to assist you.
Bio-One Hoarding is compassionate to your situation.

We contacted Bio-One after a rodent infestation was discovered at my friend's home. From the first call, they have been fantastic about walking us through the process, helping us locate a reputable company to correct a poor exclusion job done by Terminix and given us numerous suggestions on how to best handle an intolerable situation. I would highly recommend them for anyone who is facing this situation. Each and every team member we have dealt with has been very responsive, extremely professional and genuinely concerned about the best outcome for my friend.

Angela and David helped us regain our lives back. From start to finish they were nothing but caring and compassionate. Their work was outstanding. We wouldn't be where we are today without them. I can't thank them enough for all of the hard work that they did.

I recently hired Bio-One to clean out a relative's 2000 square foot house which they occupied for over 60 years. A lot of "stuff" had accumulated over the years, not only in the house but the shed too. Throw in a case of hoarding by the remaining daughter and her son, along with her sick cat that urinated on the carpeting. Due to the daughter's hoarding, infestation of cockroaches were found throughout the kitchen. Once the house was vacated Bio-One moved in to discard everything not nailed down in the house along with all carpeting. After emptying the house they deep cleaned every square inch including the insides of all cabinets, appliances and bathrooms too. The before and after pictures are a sight to be seen. He (Cuyler) and his team did it four plus days. Yes, we attempted to clean it out ourselves (five adults) but after three weekends and not making a dent, we had no choice. Bio-One sent us daily "progress pictures" along with keeping us in the loop with multiple text messages. His proposal was extremely detailed with what they were to do so there weren't any questions. Totally amazed and would highly recommend.

I have been with Bio One of Mesa for a year and have had the pleasure building up Mesa and the surrounding areas, has been a great experience from helping people in times of need to meeting wonderful people and connecting with folks and being a face of a community when they call I am there, which I never thought that could be possible. I love being a big part of the community & help out when I can! My main lesson I learned here with Bio One is “It’s Not About You! -When people know you care and are there to serve, they will knock down walls for you. Bio One Inc. has always helped out when I needed advice or help with anything. Great professional company!

Quick and very professional. As a realtor over 17 years, this is far the best company to get a house ready for re-sale.
