Bio-One Boise is a Certified Mold Remediation Contractor. Mold is commonly discovered during the home inspection as part of a real estate deal. Mold will often grow in places such as attics or crawlspaces within 24-48 hours of a moisture event. To familiarize you with the process, flip through the pics to see some of the steps taken during a recent mold remediation. In this instance, mold was discovered behind an old radiator when replacing the HVAC system.


  1. Demolition – The best treatment for mold is removal. Any porous substance affected by mold will need to be removed, while hard surfaces and structural elements can often be treated.mold behind drywall
  2. Mold Behind Drywall – What lies on the surface may be just the “tip of the iceberg.” If the mold has been growing for an extended period of time, spores/hyphae are densely populated, coverage is expansive, and/or the affected drywall is mushy, then it is likely that more mold is growing in the wall cavity. There was only a little bit of mold on the exterior base of this wall, but we found mold growing on the insulation and studs several feet up.biocide sanding hepa vacuuming
  3. Biocide/Sanding/HEPA Vacuuming - First on Step 3 is the use of a fungicide. Bio-One has a proprietary chemical that kills mold on contact and stops its growth. Second is scrubbing with an abrasive material, like a wire brush or belt sander. Various blasting methods can also be used. The last part of Step 3 is HEPA vacuuming to capture mold spores as small as 0.3 microns that were disturbed during the scrubbing process. (An air scrubber and proper containment is also necessary to prevent cross-contamination).encapsulation
  4. Encapsulation - This is the final step of the mold remediation process. It involves sealing the previously contaminated area to cover stains and deter future mold growth in the remediated area. If air tests and sampling are going to be taken, this is done prior to encapsulation to confirm the area has been restored to Condition 1.
