Mold Removal & Remediation in Rialto, 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
The ground here drains fast. Why is the bottom of the wall wet after a storm?
Because the water reached the wall before it reached the ground. Fan gravel does absorb water quickly, but a February storm on a flat lot lays down a sheet of runoff faster than the surface can take it, and that sheet crosses the yard and rides along the slab edge. Where a patio is poured against the house, rain also splashes off the concrete onto the plate line. The wall gets wet first; the gravel gets the leftovers.
What is a weep screed and why does it keep coming up on older stucco houses?
It is the metal strip at the bottom of a stucco wall that lets water behind the stucco drain out. On many 1970s tracts the stucco was run down over it or the grade was raised above it, so water that gets behind the wall covering has nowhere to go and sits against the framing. The house looks fine from outside. The fix is at the plate line, not on the surface, which is why it gets missed.
Does the wind season have anything to do with moisture?
Indirectly. The dry wind events that come off the mountains in autumn and winter bake stucco to the point where it is fully dry and slightly porous, and the first Pacific storm after one of them lands on a wall that drinks water rather than shedding it. The same rainfall on stucco that has been sitting in normal humidity does less. Watch the first storm after a wind week, not the wettest one.
