we're here to help.
Our team conducts a thorough mold inspection in Bellevue, WA, using moisture meters, thermal imaging tools, and air sampling tools before any mold removal begins. We also identify visible and non-visible contaminants behind the drywall, in the ductwork, and under the flooring to determine the origin of the moisture and, therefore, the area of remedial work.
Our team seals the contaminated zone using reinforced plastic sheeting and runs negative air pressure machines to prevent spores from spreading. HVAC registers within the zone are sealed to prevent spores from circulating through the ventilation system during removal.
Technicians use HEPA vacuum cleaners to remove spores from the surface, then apply EPA-approved antimicrobial substances to kill spores at the material level. The porous materials that cannot be decontaminated safely are removed, and the waste is disposed of in accordance with the relevant regulations. Removal of mold in molding in Bellevue includes other safety measures to prevent secondhand exposure.
Once the surface is cleaned, commercial-grade HEPA air scrubbers run through the area to remove spores that may have been floating in the air until the spore count is acceptable again. It is an obligatory process in the restoration of mold-damaged areas that complies with Bellevue regulations and determines the space's suitability for use again.
After the space has been cleared for testing, our team allows structural repairs to be made, records the source of moisture, and provides the entire remedial record to your insurer or property disclosure.
