Testing & Assessment
Mold Inspection & Testing in Rialto, CA
An assessor determines whether mold is present, identifies where it is growing, and measures how far it has spread — before any remediation quote is issued. A mold inspection locates moisture and growth that a room-level look would miss, reading wall cavities, subfloor, and the areas behind finished surfaces. The result is a scope: what is affected, what has to come out, and what is driving the moisture.
The pro who inspects is the pro who quotes
Most people reach this page after noticing something rather than after something broke: a smell that returns, a stain that spreads, a room that feels damp. An inspection answers what is actually there and where the moisture comes from, which is the information every later decision depends on. Several states, Texas among them, keep assessment and remediation as separate licensed roles specifically so the party identifying the problem is not the party selling the fix. Nothing here is medical advice — if you have health questions, those are for a clinician.

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.
