Testing & Assessment
Mold Inspection & Testing in San Bernardino, CA
An assessment establishes whether mold is present, where it is growing, and how far it extends — before anyone quotes removal. 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.
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
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.
