Mold Removal & Remediation in Ontario, 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
Fontana is ten miles east. Why isn't the Fontana Fan the story?
Fontana sits on Lytle and San Sevaine, plus Kaiser slag. This city sits on Cucamonga and San Antonio Creek fans. February's totals can look similar; the canyon mouths are different. A stain here traces to Cucamonga underflow, not to Kaiser fill.
A short wet season on the fan. How does a 1980 slab still wick in February?
Because February is a quarter of the year, and the covering has been baking since April. Gaps that were tight in November take the first flash on the fan. A dry climate does not stay sealed; it opens and then soaks all at once.
Cucamonga is boxed in concrete. How is there still water under the pad?
The box took the surface. It did not take the cobble. Cucamonga alluvium still carries underflow beside the lining, and a 1980 pad on that gravel wets from below with no overtopping. Looking at the channel walls will miss the job under the floor.
