Mold Removal & Remediation in San Bernardino, CA
Containment, HEPA filtration, and antimicrobial treatment eliminate mold colonies at the source and prevent cross-contamination throughout the property. Mold remediation removes affected porous materials and corrects the moisture source that allowed growth. The work is done under containment with HEPA filtration so spores are not carried into unaffected rooms, and the area is cleared only once the underlying moisture problem has been resolved.

Remediation is the step after the assessment, not before it. A local pro establishes how far the growth extends and what is feeding it, because removing what is visible while the moisture source is still running puts the same colony back in the same wall. Texas and several other states also set a square-footage point above which the work has to be done by a licensed remediator — the service note below covers where that line falls in this city.

Frequently asked questions
Cajon Pass is a freeway. Why would it wet a house in Del Rosa?
The pass is also a storm funnel. Pacific cells hit the San Bernardino front, squeeze through Cajon, and drop on the wash as a flash. Del Rosa sits on that fan. The freeway did not invent the path; it followed it. A February stain on the valley floor is often mountain water that never used the street.
The Santa Ana is in concrete. Is the wash still in the crawl?
The box took the surface. It did not take the gravel. Lytle and Cajon alluvium still carry underflow beside the lining, and a 1973 pad on that cobble wets from below with no overtopping. Looking at the channel walls will miss the job under the floor.
A few winter storms on Cajon alluvium. How is this not a desert pad?
Because almost a quarter of it lands in February, on ground that was a river. A dry climate opens the stucco all summer; the pass then soaks the wash in a few days. The annual total is modest. The delivery is not.
