Testing & Assessment
Mold Inspection & Testing in San Jose, 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
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.
