Beaverton, Oregon—recognized for its environmentally minded community, vibrant arts, and lush natural surroundings—deals with an ongoing challenge from its damp climate. With ~43 inches of annual rainfall and humidity levels often exceeding 70%, mold can develop quickly in homes throughout Hawthorne, Sellwood, Beaverton, and other neighborhoods.
As of September 25, 2025, Beaverton’s year-to-date rainfall stands at 19.02 inches, modestly below the historical average, yet moisture continues to be a constant threat.

In Hillsboro, Oregon, weather patterns like cool, rainy seasons and persistent humidity can drive indoor moisture that fuels mold growth—especially around crawl spaces, basements, and attics. Near landmarks such as local neighborhoods and watershed areas, homes often experience microclimates (wind-driven rain, coastal fog, or temperature swings) that trap moisture behind walls and under floors. Proactive ventilation, vapor barriers, and humidity control are essential to prevent mold spread and protect indoor air quality.

1 – Using containment and negative air pressure, we remove any building materials severely saturated or whose structural integrity has been compromised.
2 – Keeping containment and negative air in place, we set up drying equipment like fans and dehumidifiers to thoroughly dry any building materials still showing moisture.
3 – After all remaining structural materials are dry, we use a HEPA vac for horizontal surfaces, then wipe down and clean all surface areas using an antimicrobial.
4 – After all surfaces are wiped down and thoroughly cleaned, we apply our patented dry-fog sterilization process-a two-part treatment that kills and sterilizes any remaining mold spores and applies a long-term preventative, making all surfaces inhospitable to mold growth.
This process is complete top tier remediation. It ensures safe, effective mold elimination with containment, thorough drying, antimicrobial cleaning, and advanced sterilization and an encapsulating coating for long term prevention.
