Mold Removal & Remediation in San Jose, CA
Containment, HEPA filtration, and antimicrobial treatment remove mold colonies at the source and stop cross-contamination through the rest of the home. 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
The valley is dry most of the year. When does the water actually arrive?
In a few atmospheric-river days, usually in January. The rest of the year teaches the ground and the drains nothing. Hardpan sheds the first storm, creeks that have been dry since April fill in hours, and a raised crawlspace over clay fill can stay wet for weeks after the sky has cleared.
What does liquefiable fill have to do with a leak that is not a quake?
The same fill that can liquefy is a poor drain in ordinary weather. Bay-margin clay holds water against a crawlspace or a slab edge. A plumbing leak or a January storm then sits in material that will not let it down, which is why the older core stays damp longer than the alluvial fans toward the hills.
Is a slab from 1976 better or worse than a crawlspace here?
Different failures. A slab hides a supply-line leak until the flooring or a baseboard shows it. A crawlspace shows the water and also sits over clay that never fully dries. Neither assembly was built with a capillary break that this valley's fill actually needs.
