Deep Cleaning

You shouldn’t be embarrassed by asking for help. This is what we do. Whether it’s a few rooms or the whole house, Bio-One will clean without passing judgement.

You called the right 
ones for the job.

With the proper techniques, we can save many items that may have appeared lost. Because it’s far cheaper to restore than replace, we specialize in rejuvenation.

Our professional cleaning staff has been trained and certified on this very topic. The restoration we offer is just one benefit of our decluttering and deep cleaning services.


The first step of any cleaning process is to declutter. At Bio-One, we take a very compassionate, knowledgeable approach.

We understand that clutter isn’t garbage and shouldn’t be treated as such. Our crews will always treat your home and property with respect. We simply aim to organize items and remove those that are unwanted to clear room for living.

Deep Clean

Our deep clean services typically follow up decluttering. It’s an extremely thorough process. We clean and sanitize any affected areas that need attention. The places that aren’t part of a typical cleaning routine:

  • Underneath heavy appliances (fridge, washer, dryer)
  • Inside typical appliances (oven, microwave)
  • Walls, ceilings and floors
  • Windows and doors

There’s no limit to what a deep clean can look like. We work for you. In our 20+ years of experience, we haven’t forgotten that. So, whatever you want done, will be done.

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

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.

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.

Cory and his team are the best! They responded to an overwhelming job on short notice and did a great job! They hauled 5 26 foot dumpsters off the property. We called on a follow up to assist with construction trash the contractor didn’t haul away and he was there within two hours to help. His prices are reasonable and more importantly, they work with integrity and protect your family interest, protecting valuables as best they can. Hire these guys, they are Great workers.

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.

I recently decided to switch out furniture and flooring in my living room. The original 20 year old carpet had been subjected to many spills and pet "messes". Ryan and Kristi came to my house and carried away two, also 20 year old, couches and a cabinet I didn't like very much anyway. Once they got the carpet and pad up the stench of urine from various pets was horrible. They were very informative and meticulous about applying product to the floors to get the odor out. They paid special attention to areas that were especially stained. They laid down plastic over the area so the product could get into the wood. Ryan came back the next day to remove the plastic and the check for my satisfaction. The price for all of this was very reasonable and I plan to call them as I move on to the next room. Very professional and skilled!
