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.

Compassion. Experience. Respect.

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.

    WHY CHOOSE Bio-One of Pacific North West

    We are here for you when you need us the most

    Organic material and water are all that is needed for mold to grow. Mold spores are ubiquitous, so excess moisture in an indoor environment is usually the cause. Common causes of excess moisture include floods, plumbing leaks, and poor ventilation resulting in increased relative humidity levels. Addressing the source of moisture is the first step in the remediation process.

    Common areas to check for mold are:

    • Attics
    • Crawlspaces
    • Bathrooms
    • Under sinks
    • Washer/Dryer hookups

    Under the right conditions, mold can begin to colonize within 24-48 hours. It is imperative to dry out any floods or plumbing leaks right away. When exposed to water, the mold spores quickly grow – the spores may enter your house through doors, windows, or your HVAC system. Mold is present almost everywhere both indoors and outdoors.

    Bio-One Nw technicians can quickly stop and remove the fungus that occurs naturally in areas subjected to humidity, condensation, water leaks and insufficient ventilation. Hiring a professional mold removal company is critical as inadequate removal, remediation and treatment of mold spores can lead to health risks that include respiratory complications, skin irritation and severe allergic reactions.

    Our Bio-One Nw team properly contains areas infested with mold and discards any household or business items that have been highly contaminated, whether that entails tearing out and reconstructing areas or less thorough mold removal procedures. The remediation may include minor or major repairs, dependent on the level of mold damage.

    Bio-One Nw crews are available 24/7 and provide mold remediation services and other cleanup services for properties such as residential homes, vehicles, communities, and businesses. If prevention fails, Bio-One Nw can be there to remediate the mold in a safe and contained way to prevent the spores from travelling to other areas of the home.

    I want to give a huge shout out to the Bio-One team for the amazing job they did for a family member’s basement. To give you an idea of the horrific state of the basement, let me say two words…. Hoarder and Rats. After getting Pest Control in to eradicate the rats, I called Bio-One to see what they could do to help. Sean was amazing at getting a team out to the house and reassuring me that they could take care of everything. Because of the magnitude of the items to be removed and the clean up afterwards, Sean sent out a team of four. These guys are incredible. I can’t say enough about Jason, Travis, Joe and Jaz. These guys worked hard, quickly and efficiently and even though this was really nasty, heavy, and hard work, I never saw anyone slacking. Everyone, from Sean in the office to the guys in the field (Jason, Travis, Joe and Jaz) were professional, kind and courteous. Just as Sean promised, they took care of everything, from getting rid of all the items from 60 years of hoarding, cleaning/vacuuming up EVERYTHING, and disinfecting the entire basement from top to bottom. I am so appreciative of all they did, and I would give them more than 5 stars if possible.
